Hairspray and aerosol spray cans contain very toxic chemicals that when released into the atmosphere become gas and cause air pollution. As these gases rise up they can cause harmful effects to the ozone layer, which in turn causes an increase of UV-B light that causes global warming on earth.
Does Hairspray destroy the ozone in your apartment?
He also said using hairspray in his apartment, “which is all sealed,” would prevent any ozone-depleting substances from escaping into the environment. But these chemicals would still make their way out, multiple experts told us.
Is Hairspray bad for the environment?
Many countries began phasing out the ozone-depleting substances in hairspray in the late 1980s, but these regulations wouldn’t affect the quality of hairspray. He also said using hairspray in his apartment, “which is all sealed,” would prevent any ozone-depleting substances from escaping into the environment.
Is Hairspray still made with chemicals?
But these chemicals would still make their way out, multiple experts told us. Hairspray is made up of chemicals that make hair stiff and a propellant. Hairspray and many other aerosols used chlorofluorocarbons as propellants until many major countries began phasing out these chemicals after the signing of the Montreal Protocol in 1987.
What happens to CFCs in Hairspray?
Rather than assume, as others had, that CFCs had no effect on the environment, Rowland and Molina decided to scientifically examine the question of what happens to CFCs released into the atmosphere. What they found would not only alter the contents of hairspray, but would also earn them a Nobel Prize and change environmental policy the world over.

What sprays damage the ozone layer?
The chemicals used to propel product in aerosol bottles were called CFC's (Chlorofluorocarbons). In the 1970's scientists discovered that CFC's were accumulating in the environment, and depleting the earth's ozone layer. The U.S. banned CFC's in the 1970's.
What products harm the ozone?
The main uses of ozone depleting substances include:CFCs and HCFCs in refrigerators and air conditioners,HCFCs and halons in fire extinguishers,CFCs and HCFCs in foam,CFCs and HCFCs as aerosol propellants, and.methyl bromide for fumigation of soil, structures and goods to be imported or exported.
Are aerosols bad for the ozone layer?
One of the worst aerosol environment effects is air pollution. VOCs, contained in traditional aerosol cans affect the environment by constantly contributing to the formation of ground-level ozone.
Does hair spray contribute to air pollution?
Common household cleaners and aerosol sprays, such as hairspray, contain pollutants called VOCs, which stay in the air that you breathe. Carpets and furniture are great at holding onto small particles and dust.
What destroys ozone the most?
Ozone Depletion. When chlorine and bromine atoms come into contact with ozone in the stratosphere, they destroy ozone molecules. One chlorine atom can destroy over 100,000 ozone molecules before it is removed from the stratosphere. Ozone can be destroyed more quickly than it is naturally created.
What damages ozone most?
The best-known and most abundant of the ODS are the CFCs . A single atom of chlorine from a CFC can destroy 100,000 or more molecules of ozone. Ozone depletion only stops when the chlorine randomly reacts with another molecule to form a long-lived, stable substance.
Is perfume harmful to ozone layer?
Each spritz of your perfume contains "volatile organic compounds (VOCs)." Once you spray, the VOCs react with sunlight and other chemicals in the atmosphere to form ozone pollution, NOAA explains. VOCs can also be damaging to your health.
Is aerosol hairspray bad for the environment?
Hairspray and aerosol spray cans contain very toxic chemicals that when released into the atmosphere become gas and cause air pollution. As these gases rise up they can cause harmful effects to the ozone layer, which in turn causes an increase of UV-B light that causes global warming on earth.
Are hair sprays bad for you?
When used as directed, hairspray is minimally toxic. Unintentional eye contact, inhalation, or ingestion of small amounts of hairspray might produce minor irritating effects. Irritation should improve by rinsing the eyes or mouth or getting fresh air. Deliberate swallowing or inhaling hairspray can be very dangerous.

Does hairspray cause lung problems?
Compared with control cells, the hairspray-exposed macrophages showed increased numbers of lysosomes as well as lipid vacuoles. These findings indicate that hairspray can induce pulmonary lesions.
Does hairspray cause global warming?
It turns out that most aerosols are cooling — that is to say, they reflect the sun's energy back out into space. There is only one aerosol — soot, also known as black carbon — that actually helps contribute to global warming by boosting the warming effects of greenhouse gases in the atmosphere.
How does aerosol affect the atmosphere?
Aerosol particles affect the Earth's climate by acting as the seeds on which clouds form. More aerosol particles can lead to more, but smaller, cloud droplets. This may reduce the rain that falls from that cloud. Aerosol particles also shape the climate as they circulate in the atmosphere.
How does aerosol affect the environment?
What do aerosols do to climate? Aerosols influence climate in two primary ways: by changing the amount of heat that gets in or out of the atmosphere, or by affecting the way clouds form. Some aerosols, like many kinds of dust from ground-up rocks, are light-colored and even a little bit reflective.

Aerosol Sprays Do Not Damage the Ozone Layer - Today I Found Out
Myth: Aerosol sprays damage the Earth’s ozone layer. This misconception stems primarily from the fact that, originally, aerosol cans used chlorofluorocarbons as a propellant. Chlorofluorocarbons were also used commonly in refrigerators, air conditioners, and for many industrial applications. Chlorofluorocarbons were particularly popular because they are non-flammable, non-toxic, and non ...

How do CFCs destroy the ozone layer? - LifeGate
Fortunately, chlorine has “natural enemies” as well, such as methane (CH4). Thanks to them, the natural ozone layer could recover over 50 years, as long as CFCs are no longer used on a global level.
What are the VOCs in sprays?
The state of California is now regulating consumer products that contain VOCs—and aerosol sprays are not the only targets: Fingernail polish , perfumes, mouthwashes, pump hair sprays, and roll-on and stick deodorants also emit them.
Is shaving cream good for the environment?
Of course, just because those deodorant sprays and shaving cream cans aren’t depleting the ozone layer doesn’t mean they are actually good for the environment. They still contain hydrocarbons and/or compressed gases notorious for their contribution to global warming.
Do aerosols contain CFCs?
According to the industry trade group, the National Aerosol Association, aerosol manufacturers in Europe and other parts of the world initially did not follow the lead of U.S. industry in substituting alternative propellants for CFCs. “The fact that aerosols made in underdeveloped countries may contain CFCs has caused confusion in press reports and in the public mind about the stratospheric ozone/aerosol link,” reports the group. Other countries have also switched out ozone-depleting propellants with non-depleting forms because they signed 1987’s Montreal Protocol, a landmark international agreement signed by 191 countries with the goal of phasing out the production and use of CFCs and other ozone depleting chemicals. Scientists report that that the phase out of the chemicals is now about 90 percent complete.
Can you use CFCs in aerosol spray?
now use propellants—such as hydrocarbons and compressed gases like nitrous oxide—that do not deplete the ozone layer. Aerosol spray cans produced in some other countries might still utilize CFCs, but they cannot legally be sold in the U.S.
When was aerosol spray invented?
The aerosol spray can has a storied history in the United States. First invented in the 1920s by U.S. Department of Agriculture scientists to pressurize insect spray, American soldiers eventually used the technology to help ward off Malaria in the South Pacific during World War II.
What happens when CFCs float up into the stratosphere?
But when CFCs float up into the stratosphere, they react with UV rays, Maguire said. The reaction cleaves off one of the chlorine atoms of a CFC molecule, which in turn can react with ozone, breaking it down, he said. The problem is that after chlorine breaks down one ozone molecule, the chlorine is "spit out" and keeps going, breaking down more and more molecules of ozone, he said.
What is the purpose of CFC in hair spray?
CFC molecules, which are made up of chains of carbon atoms with chlorine and fluorine atoms attached, acted as a propellant to force the liquid hair spray out of the can and disperse it into the air, Maguire told Live Science. Otherwise, hair spray would just be a liquid, he said.
What happens when CFCs are used in products?
Eventually, when CFCs were being used in products, the rate of ozone breaking down was higher than the rate of ozone being formed , he said.
How does HCFC change chemistry?
But the extra hydrogen atom an HCFC molecule changes its chemistry in a way that lets the whole molecule be broken down and destroyed, Maguire said. Unlike CFC molecules, which can each break down many molecules of ozone, if HCFC molecules get up into the stratosphere, they might break down one ozone molecule, but then they would stop, he said.
When were CFCs first discovered?
The compounds were first developed the 1930s , Maguire said. At that time, scientists thought CFCs didn't react with any other compounds, he said. Researchers figured the substance was basically inert, he said. It wasn't until decades later that scientists realized CFCs react with ozone molecules, he said.
What product did Donald Trump use to grieve?
At a rally on Thursday in West Virginia, presidential candidate Donald Trump aired grievances over a product that appears to play a role in his daily life: hair spray.
Does chlorine break down ozone?
The problem is that after chlorine breaks down one ozone molecule, the chlorine is "spit out" and keeps going, breaking down more and more molecules of ozone, he said. The more CFCs there are in the atmosphere, the more ozone is broken down, Maguire said.
What are the differences between CFCs and HFCs?
But HCFCs are about 5 percent to 10 percent as potent at depleting ozone as CFCs, while HFCs are generally not thought of as ozone-depleting substances.
Why is hairspray not like it used to be?
Trump said “hairspray’s not like it used to be” because chemicals in it that affect the ozone layer have been banned. Many countries began phasing out the ozone-depleting substances in hairspray in the late 1980s, but these regulations wouldn’t affect the quality of hairspray.
Why are CFCs bad for the environment?
To be clear, CFCs are detrimental to the environment for at least two reasons — they efficiently deplete ozone and they are potent greenhouse gases. That is, they contribute to global warming. HFCs, on the other hand, do not contribute to ozone depletion directly and efficiently like CFCs.
How many times has Trump made claims about hairspray?
Trump has made claims about hairspray and the ozone layer at least three times. Back in 2011 in Sydney, he implied the “eight-inch concrete floors” and “eight-inch concrete walls” of Trump Tower would prevent hairspray from “destroying the ozone that’s 400 miles up in the air.”. In December 2015, at a campaign rally in Hilton Head Island, ...
How many ozone molecules can a chlorine atom break up?
In fact, Molina discovered that one chlorine atom could start a chain reaction that would lead to the break up of around 100,000 ozone molecules. First off, a CFC molecule doesn’t have 400 miles to travel to reach the ozone layer, as Trump claimed in 2011.
How many countries have signed the HCFC protocol?
First signed by 46 countries, the protocol now has close to 200 signatories, including the United States.
How far above Earth's surface is the stratosphere?
The stratosphere spans 5.5 to 30 miles above the earth’s surface. Second, a depleted ozone layer is no small matter. A weakened ozone layer leads to an increase in ultraviolet radiation, which then brings about higher rates of skin cancer, cataracts and immune system problems in human populations.
How long does hairspray last?
The Verge reports a single CFC molecule can last for as much as 20 years and can destroy 100,000 ozone molecules.
Do hairsprays have CFCs?
The treaty forced many companies to change how they make products to avoid things like CFCs. This means today's hairsprays don't have CFC ... but also don't have the same holding power as in the 80s, explains Chemical Processing. We're not out of hot water yet, however.
How did Lovelock find CFCs?
looking for these chemicals in the air would be a good test. Using an instrument he’d designed himself, he detected CFCs in the haze, confirming its human- made origins. However, what really piqued his curiosity were the results on clear days. According to his hypothesis, on clear days, when the air was coming from over the Atlantic without having passed over an urban area for thousands of miles, CFCs should be close to undetect- able. Surprisingly, he was easily able to detect CFCs even on pristine days. Wanting to know if CFCs were building up in the atmosphere everywhere, Lovelock brought his instrument on a sea voyage from England to Antarctica, taking measurements all along the jour- ney. Wherever he traveled, he found CFCs. Lovelock presented his findings in 1972 at a scientific meeting that aimed to bring together meteorologists and chemists—two sets of researchers which, up to this point, had mixed very little. There, his observa- tions caught the attention of Sherwood Rowland, a chemist at the University of California, Irvine. Rowland was curious about what happened to these chemicals once they were released into the atmo- sphere. Even very stable chemicals can react under the right conditions; for example, even stainless steel will react when it’s exposed to salty water and high tem- peratures. Rowland wanted to know what the right conditions were for CFCs to react and what effects this might have.
What caused the ozone loss in Antarctica?
Based on her expertise in modeling atmospheric chemistry and air movements, Solomon suspected that some unknown chemical processes involving CFCs or CFC products were causing these losses. Racking her brain for something that might be missing from the models, Solomon re- called an unusual phenomenon that occurs in Antarc- tica: high-altitude clouds of ice particles, called polar stratospheric clouds (Fig. 24), that form in the ozone layer. Curious, she and colleague Rolando Garcia (Fig. 23, right), a fellow atmospheric scientist, built an atmospheric model that in- cluded these polar clouds, with the ice particles providing a solid surface on which reactions could occur. This seemingly small change in the hypothesis led to big changes in the results—the model was now predicting a large ozone loss. It looked like the presence of these tiny ice crystals made the destruc- tion of ozone from CFCs much more efficient. With some prelimi- nary results in hand, Solomon contacted Rowland. As it happened, Rowland was also wondering what would happen if solid surfaces were added into atmospheric models. Through laboratory experi- ments, he had already found that some key reactions (e.g., the re- lease of destructive chlorine from ozone-friendly chlorine nitrate) occurred more readily on the surface of solids like glass and Teflon—and by extension, perhaps also ice from polar clouds. Since Rowland was on a similar track to Solomon and Garcia, they decided to collaborate. With their proposed reac- tions, they explained how ice particles from the seemingly harmless clouds could not only free ozone-destroying chlorine, but also tie up the chemicals that could take chlorine out of com- mission, like nitrogen dioxide (Fig. 25). The model they created with these reac- tions was able to match the Antarctic ozone observations, but more evidence was needed to determine if the ice clouds were really to blame for the ex- tent of ozone destruction in Antarctica.
What was the ozone reading in 1982?
CFCs. In 1982, his ozone reading showed a dramatic dip—around 40%. Rather than being alarmed, he was skeptical of the data and thought it must be an instrument malfunction. The machine was notoriously difficult to keep working in the severe Antarctic cold, and this particular instrument was old. Besides, he reasoned, NASA scientists had satellites collecting atmospheric data from all over the world, and they hadn’t reported any anomalies. Farman’s instrument was ground-based and only had one data point—the part of the at- mosphere directly above it. Surely NASA’s thousands of data points would have revealed a drop in ozone if there had been one. Farman ordered a new instrument for next year’s measurement. But the following year, Farman still found a drastic decline. He dug up his old data and found that the decline had really started back in 1977 (Fig. 21). Now Farman suspected that something odd was happening strictly over Halley Bay, leaving other areas unaffected. So the next year, his team took measurements from a location 1,000 miles northwest of Halley Bay. Even there, a large decline in ozone occurred. The mounting evidence was undeniable. Farman decided it was time to publish his data. Why hadn’t NASA’s satellite caught this plunge in ozone levels? Much to their chagrin, NASA scientists realized that they did have data indi- cating ozone loss but had overlooked it. Since their satellite recorded data 24 hours a day, it supplied scientists with information much fast- er than they could analyze it. To deal with this deluge, a data process- ing program had been set up to filter out all measurements below or above cut-off values that were considered to be impossible for actual ozone measurements. This program was based on the assumption that these “impossible” measurements were due to instrument malfunc- tions. The two groups of scientists (Farman’s group and the NASA group) looked at the same data, but interpreted them differently because of their data analysis techniques. Farman’s group concluded that the data reflected real changes in ozone, while the NASA group had conclud- ed that the data reflected an instrument problem. Farman’s evidence showed NASA’s group the problem with their data analysis procedure. When NASA sci- entists reanalyzed their Antarctic measurements, they discovered a gigantic hole in the ozone layer—a re- gion of depleted ozone the size of the United States (Fig. 22)! Our protective shield from solar radiation had already been damaged even more than scientists had thought possible. The ozone depletion in Antarc- tica was real, but why was it so much larger than any of the models had predicted?
What is the chemical that destroys ozone?
The object of attention was chlorine monoxide (Fig. 16)—one of the products of ozone destruction. Since there is no other known source of chlorine monoxide, find- ing this chemical in the upper atmosphere would strongly support the idea that chlorine is destroying ozone (Fig. 17). However, the amount of chlorine monoxide scientists were looking for was miniscule—it would be like trying to detect a single drop of dye in an Olympic-sized swimming pool full of water. The task was even more challenging because the sensitive instruments necessary to detect the molecules had to be ballooned up into the atmosphere, take measure- ments quickly, and survive the parachute ride back down to earth (Fig. 18). De- spite these difficulties, atmospheric scientist James Anderson succeeded in getting
What caused Molina and Rowland to revise their hypothesis?
New observations in the lab caused Molina and Rowland to revise their hypothesis. However, the updated hypothesis incorporating nitrogen dioxide still led them to expect significant ozone depletion.
What is the reaction between chlorine monoxide and nitrogen dioxide?
In the presence of another molecule to serve as a catalyst (not shown), nitrogen dioxide (NO2) and chlorine monoxide (ClO), a byproduct of the breakup of ozone molecules by CFCs, react to form chlorine nitrate (ClONO2). Sherwood and Molina found that chlorine nitrate did not break down in the atmosphere as quickly as they had thought—could the formation of this molecule actually decommission ozone-damaging chlorine atoms? Figure 15. Researchers needed to incorporate nitrogen dioxide into the hypothesis—but they weren’t sure how it would affect the expectations generated by the hypothesis. Would we still expect to see significant ozone depletion?
What happens to CFCs as they drift upwards?
At low alti- tudes, much solar radiation has been filtered out by the atmosphere, but at high altitudes, solar radiation is much more intense. From his understanding of chem- istry, Molina knew that once any molecule got high enough, strong solar radiation would break it apart (Fig. 5). Using atmospheric scientists’ discoveries about air movement, Molina calculated that it would take somewhere between 40 and 150 years for a CFC molecule to randomly diffuse up to the height where it would be broken down by solar radiation, releasing a chlorine atom in the process. To find out what would become of this chlorine atom, Molina searched through other scien- tists’ publications to see what atmospheric molecules would be near this chlorine atom when it split off. Among the many possibilities, one molecule stood out: ozone—three oxygen atoms linked together. Molina learned that chlorine would react catalytically with ozone—meaning that the chlorine atom could act like an axe, encouraging a reaction that chops up ozone without hurting the chlorine at all. In fact, a single chlorine atom could destroy around 100,000 ozone molecules (Fig. 6)! Molina wasn’t sure how big a difference this would make in the atmosphere, so he compared effects of CFCs to natural ozone deple- tion mechanisms investigated by other researchers. He found that CFCs could lead to even more ozone destruction than the natural mechanisms did! Sounding the alarm The ozone layer protects Earth from dangerous UV radiation (Fig. 7)—which can cause mutations. In humans, a depleted ozone layer would likely mean high- er rates of skin cancer, cataracts, and immune system problems. Further, an in- crease in UV radiation could affect plants and marine ecosystems in unpredictable ways—which could, in turn, trigger other ecological changes. Because it seemed that CFCs could destroy our protective ozone shield, Molina and Rowland were alarmed! But they were also skeptical: if this ozone destruction were actually going on, why hadn’t atmospheric scientists discovered it already? After checking their calculations, they decided to consult a colleague in atmospheric chemistry and learned that, only a few months earlier, researchers had found the same chlorine- ozone interaction in the exhaust from space shuttles—a very small cause of ozone destruction compared to CFCs. After being assured that their findings warranted serious concern, Molina and Rowland published their work.1Then, to increase the likelihood that action would be taken on these disturbing results, they took their findings to the news, media, and policymakers, calling for a ban on the production and use of CFCs. But they didn’t stop there …
