What is It?
-Phosphorous is a nutrient; essential for plant growth.
-Phosphorous in our environment is found as inorganic phosphates and organic phosphates.
Why is it in the environment?
-The organic form is found in living plants, animals, and animal by-products.
-Inorganic Phosphorous is found in soil particles as well as in certain household detergents.
-Phosphorus is a limiting and increased levels of Phosphorous will result in eutrophication- the immense growth of aquatic vegetation due to excessive nutrients.
-Fertilizers, pesticides and cleaning compounds are the most prevalent causes of phosphorus contamination in surface waters.
How does it affect water quality?
-Agricultural run-off and other non-point source pollution contribute to eutrophication.
-The increased plant growth causes a depletion of oxygen in the water due to the heavy oxygen demand and reduced dissolved Oxygen.
How does it affect adults?
-It has not been shown that Phosphorous adversely effects human health.
How does it affect children?
-It has not been shown that Phosphorous adversely effects human health
What are the EPA regulations?
-Phosphates should not exceed .05 mg/l if streams discharge into lakes or reservoirs.
-.025 mg/l within a lake or reservoir.
-And .1 mg/l in streams or flowing waters not discharging into lakes or reservoirs to control algal growth.
