Why is phosphorus bad for the environment?
Phosphorus is bad for the environment because it causes eutrophication. Excess phosphorus leaching from agricultural land gets into aquatic systems and causes eutrophication. The overabundance of phosphorus in the water system causes accelerated growth of algae which in turn causes anoxic events where oxygen become so depleted that it kills aquatic life in the affected body of water.
Why is phosphorus important to plants?
Phosphorous is required in the human body for the formation of bones and teeth. It forms 1% of the body by weight. It is also required by plants and is thus a major component of fertilisers. HOWEVER too much phosphorus in the soil can be leached and run away into rivers or other water supplies causing pollution. (Although plants need phosphorus they do find it hard to take it up, so large amounts will stay in the soil).

What can phosphorus tell us about the condition of water?
Phosphorus is usually considered the “limiting nutrient” in aquatic ecosystems, meaning that the available quantity of this nutrient controls the pace at which algae and aquatic plants are produced. In appropriate quantities, phosphorus can be used by vegetation and soil microbes for normal growth. However, in excess quantities, phosphorus can lead to water quality problems such as eutrophication and harmful algal growth. Some aquatic resources, such as wetlands, naturally serve as sinks for phosphorus found in sediments or dissolved in water. However, since phosphorus generally occurs in small quantities in the natural environment, even small increases can negatively affect water quality and biological condition.

Why is phosphorus not likely to spread?
White phosphorus is not likely to spread, because it reacts with oxygenfairly quickly. When phosphorus ends up in air through exhausts it will usually react with oxygen right away to be converted into less harmful particles. However, when phosphorus particles are in air they may have a protective coating that prevents chemical reactions.
How does white phosphorus enter the environment?
White phosphorus enters the environment when industries use it to make other chemicals and when the army uses it as ammunition . Through discharge of wastewaterwhite phosphorus ends up in surface waters near the factories that use it.
Why are phosphates low in the ocean?
The reason lies partly within the insolubility of aluminumand calciumphosphates , but in any case in the oceans phosphate is quickly used up and falls into the deep as organic debris. There can be more phosphate in rivers and lakes, resulting in excessive algae growth. For further details go to environmental effects of phosphorous.
How long does phosphorus stay in water?
In water, white phosphorus is not reacting with other particles that quickly and as a result it will accumulate in the bodies of aquatic organisms. In soil phosphorus will remain for several days before it is converted into less harmful substances. But in deep soils and the bottom of rivers and lakes phosphorus may remain for a thousand years or so.
How did humans change the phosphate supply?
Humans have changed the natural phosphate supply radically by addition of phosphate-rich manures to the soil and by the use of phosphate-containing detergents. Phosphates were also added to a number of foodstuffs, such as cheese, sausages and hams.
What is the difference between white phosphorus and red phosphorus?
White phosphorous is the one manufactured industrial; it glows in the dark, is spontaneously flammable when exposed to air and is deadly poison. Red phosphorous can vary in colour from orange to purple, due to slight variations in its chemical structure. The third form, black phosphorous, is made under high pressure, looks like graphite and, like graphite, has the ability to conduct electricity.
Why is the phosphor cycle disrupted?
Due to the constant addition of phosphates by humans and the exceeding of the natural concentrations, the phosphor cycle is strongly disrupted. The increasing phosphor concentrations in surface waters raise the growth of phosphate-dependent organisms, such as algae and duckweed.
Why is phosphorus important for the body?
