What are the effects of sulphur dioxide on human body?
Sulfur dioxide affects human health when it is breathed in. It irritates the nose, throat, and airways to cause coughing, wheezing, shortness of breath, or a tight feeling around the chest. Those most at risk of developing problems if they are exposed to sulfur dioxide are people with asthma or similar conditions.
What are the natural sources of sulfur dioxide?
Volcanic activity and fossil fuels are the main natural sources of sulfur dioxide in the environment. Sulfur dioxide is the most harmful gaseous pollutant which has adverse effects on our environment and human health. It causes air, water, and soil pollution in our environment. The structure of sulfur dioxide molecule contains sp 2 hybridized ...
What happens when sulphur reacts with water?
Sulfur does not react with water. If you put the two together, the sulfur will float on the surface of the water or at best, the sulfur will get wet. If you want sulfur to react with water you must first react sulfur with oxygen to form SO [math]_2.math] S + O [math]_2[/math] → SO [math]_2[/math]
What are the symptoms of sulfur dioxide?
Sulfur dioxide irritates the skin and mucous membranes of the eyes, nose, throat, and lungs. High concentrations of SO 2 can cause inflammation and irritation of the respiratory system, especially during heavy physical activity. The resulting symptoms can include pain when taking a deep breath, coughing, throat irritation, and breathing difficulties.

What are the environmental effects of SO 2 and other sulfur oxides?
At high concentrations, gaseous SOx can harm trees and plants by damaging foliage and decreasing growth.
What can deposition of particles do to a stone?
Deposition of particles can also stain and damage stone and other materials , including culturally important objects such as statues and monuments.
What is SO 2?
SO 2 is the component of greatest concern and is used as the indicator for the larger group of gaseous sulfur oxides (SO x ). Other gaseous SO x (such as SO 3) are found in the atmosphere at concentrations much lower than SO 2 .
What is sulfur dioxide?
Sulfur dioxide causes reduced ventilatory function, bronchoconstriction, and sulfite sensitivity. Sulfur dioxide raises the odds of respiratory depression and subsequent death. Sulfur dioxide may trigger the onset of severe skin allergies and eye damage. Sulfur dioxide is particularly detrimental to the respiratory system’s overall health.
What is the source of sulfur dioxide in the air?
The article also notes that sulfur dioxide contamination in the air stems from various human activities including copper smelting and the burning of coal and oil.
How long does it take for sulfur dioxide to cause respiratory depression?
According to a San Francisco Chronicle article , up to 10 percent of asthma patients may negatively react to the air pollutant. Even relatively short exposure to sulfur dioxide may lead to respiratory depression and subsequent death. The scientific community warns that exposure to the toxic chemical between 10 minutes and several hours may raise ...

How does sulfur dioxide affect the environment?
Even small amounts of sulfur dioxide can harm plants and trees and slow down their growth, so farmers have fewer crops to harvest.
What effect does sulfur dioxide have on the environment?
Sulfur dioxide can have serious effects on our environment. It is absorbed by soils and plants, affecting our land and water ecosystems, and it can even be captured within and below clouds, which increases the chance of acid rain.
Where does sulfur dioxide come from?
However, it is found naturally in the environment and we use it in a wide variety of ways — from preserving yummy fresh fruit to cleaning our toilets with bleach!

What are some products that contain sulfur dioxide?
Common products containing sulfur dioxide include foods, such as dried fruit, preserved fruit, food preservatives, as well as wine, bleach, disinfectant and fumigants which are used to control pests.
What industries emit sulfur dioxide?
Industries that carry out activities such as wood pulping, paper manufacturing, petroleum and metal refining and metal smelting, especially of ores containing sulfides, such as lead, silver and zinc, all emit sulfur dioxide into the air. Fossil fuel combustion, such as in coal-burning power plants, also emits sulfur dioxide.
What are some of the other sources of sulfur dioxide?
What are some of the other sources? Textile bleaching, wineries, and fumigation, where fruit growers and farmers spray their crops to keep insects away, are also sources of sulfur dioxide. What effect does sulfur dioxide have on the environment? Sulfur dioxide can have serious effects on our environment.
How does sulfur dioxide affect national parks?
Sulfur dioxide can convert to acids in the atmosphere and come down from the atmosphere in rain, snow, or fog, or as dry particles. This atmospheric deposition can damage vegetation, affect soils, acidify lakes and streams, and ruin memorials, buildings, and statues at our national cultural monuments.
What is sulfur dioxide?
Sulfur dioxide (SO 2) is a colorless, reactive air pollutant with a strong odor. This gas can be a threat to human health, animal health, and plant life.
What are the NPS sulfur dioxide health advisories?
A SO 2 air pollution advisory program was created at Hawai'i Volcanoes NP to deliver timely information about possible unhealthy air pollution conditions that could affect the health of visitors, island residents, and park personnel. Using the Environmental Protection Agency (EPA) air quality index, the NPS SO 2 health advisories for Hawai'i Volcanoes NP help you understand what local air quality means to your health. The air quality index is divided into six levels of health concern:
How much sulfur dioxide is in Kilauea?
The Halema'uma'u plume in Kilauea Crater at Hawai'i Volcanoes NP contains extremely high levels of sulfur dioxide, about 500-1,000 tones/day. The NPS sulfur dioxide advisory program alerts the public and park staff if air quality conditions reach unhealthy levels.
Can sulfur dioxide be harmful?
When possibly unhealthy sulfur dioxide pollution happens, your chances of being affected increase with high levels of activity and the length of time you are active outdoors. If your planned activity has long or heavy physical exertion and the sulfur dioxide levels are high, you may want to limit or stop your activity.
