This study aids in the broader understanding of the complex mechanisms that influence harmful algal bloom progression in bodies of water rich in organic nutrients such as phosphorus and nitrogen, and points to the direct need to reduce nutrient pollution in the face of both urban and agricultural development.

«We also found that most palms do not need any phosphorus in their fertilizer to be healthy, and by not applying this element, we can eliminate one possible source of water pollution in Florida,» said Broschat, a faculty member at UF's Fort Lauderdale Research and Education Center.

«In 40 % of Europe's lakes the water quality does not meet the demands of EUs Water Framework Directive, mainly due to phosphorus pollution.

ref Specifically, reducing land - based sources of pollution (nutrient runoff and sedimentation) has been identified as an important approach to address acidification in coastal waters because nutrients like phosphorus and nitrogen and land - based carbon inputs can increase the acidity of coastal and oceanic waters.

Phosphorus pollution causing algal blooms in Lake Erie alone has reduced the lake's tourism value by $ 4 billion; shoreline properties by another $ 700 million.

Inefficient nitrogen and phosphorus use in agriculture, along with industrial pollution, underpin the environmental challenges listed above.

Concerted efforts to reduce nitrogen and phosphorus pollution from industry, improve the efficiency of their use in agriculture, and enhance their availability for use in fertilizer in food - insecure regions would have multiple benefits, including a reduction of climate risks.

The opportunities for improvement are even greater in rapidly developing economies such as China, which now uses much more nitrogen and phosphorus fertilizer much less efficiently than either the United States or Europe, and at a much higher cost in pollution and human health.

However, we are a long way from achieving an equitable, efficient, and sustainable use of nitrogen and phosphorus in agriculture, and we are not close to reducing nitrogen and phosphorus pollution to tolerable levels.

Agricultural runoff, in combination with increased water temperatures, has caused considerable non-point source pollution problems in recent years, with increased phosphorus and nitrogen loadings from farms contributing to more frequent and prolonged occurrences of anoxic «dead zones» and harmful, dense algae growth for long periods.

But pollution also covers hundreds of chemicals which are fine or even beneficial at low levels but which if released in large quantities or in problematic circumstances cause «harm» — like phosphorus (grows your veges but also leads to toxic cyanobacterial blooms which kill cattle), nitrogen (grows crops kills many native species of plants and promotes weed growth costing farmers), copper (used as an oxygen carrier by gastropods but in high concentrations kills the life in sediments which feed fish), hormones like oestrogen (essential for regulating bodies but in high concentrations confuse reproductive cycles especially with marine life) or maybe molasses from a sugar mill (good for rum but when dumped into east coast estuaries used to cause oxygen sag in estuaries leading to massive fish kills).

Over 60 % of American coastal rivers and bays have been negatively impacted by phosphorus pollution, and there are currently at least 166 coastal «dead zones» in the United States.

Nutrients like phosphorus and nitrogen are necessary for plant growth, but excess nutrients in a water system can cause a dangerous form of pollution known as eutrophication.
