Phosphorus

Phosphorus Plants
Facilities using electric furnaces to produce elemental phosphorous for commercial use, such as high grade phosphoric acid, phosphate-based detergent, and organic chemicals use.

Phosphorus: An essential chemical food element that can contribute to the eutrophication of lakes and other water bodies. Increased phosphorus levels result from discharge of phosphorus-containing materials into surface waters.

phosphorus
An element essential to the growth and development of plants, but which, in excess, can cause unhealthy conditions that threaten aquatic animals in surface waters.
photodegrade ...

P phosphorus
Definition (english only)
It is an essential component of living systems and is found in nervous tissue, bones and cell protoplasm.

fixed phosphorus
(1) Phosphorus that has been changed to a less soluble form as a result of reaction with the soil; moderately unavailable phosphorus.

total phosphorus. The sum of all phosphorus forms.
total residual chlorine. The amount of available chlorine remaining after a given contact time. The sum of the combined available residual chlorine and the free available residual chlorine.

macronutrients nutrients needed in relatively large amounts, such as phosphorus, calcium, magnesium, potassium, sulfur, nitrogen, chlorine, and sodium
macrophyte a large plant, as opposed to small and microscopic plants such as algae ...

Soil organic matter serves as the primary source of three important plant nutrients: nitrogen, phosphorus, and sulfur. Soil organic matter compounds serve as binding agents, which aggregate smaller soil particle into larger, more stable units.

Compost is rich in plant nutrients such as nitrogen, phosphorus and potassium and acts as a sponge to help retain moisture. Adding compost to soil and covering the soil with mulch helps to protect the soil and enable it to produce nutritious food.

For water-quality investigations the various forms of nitrogen and phosphorus are the nutrients of interest.

Biosolids contain nitrogen and phosphorus along with other supplementary nutrients in smaller doses, such as potassium, sulfur, magnesium, calcium, copper and zinc. Soil that is lacking in these substances can be reclaimed with biosolids use.

Sandstorms blowing west off Africa take phosphate out towards the Atlantic Ocean and even as far as South America. This phosphate may be an important source of phosphorus in phosphorus-limited biomes. [U. Brunner and R.

Nutrients: Elements (e.g., nitrogen and phosphorus) and trace elements (including sulfur, potassium, calcium, and magnesium) that are essential for the growth of organisms.

Enrichment: The addition of nutrients (e.g. nitrogen, phosphorus, carbon compounds) from sewage effluent or agricultural runoff to surface water, greatly increases the growth potential for algae and other aquatic plants.

Pesticides that contain phosphorus; short-lived, but some can be toxic when first applied.
Organophyllic
A substance that easily combines with organic compounds.

A group of organic (carbon-containing) insecticides that also contain phosphorus. Although they do not have a long life, some can be very toxic when first applied. Malathion and Parathion are organophosphates.

phosphates Certain chemical compounds containing phosphorus.
phosphorous An element that, while essential to life, contributes to the eutrophication of lakes and other bodies of water.

Eutrophication: degradation of water quality due enrichment by nutrients, primarily nitrogen (N) and phosphorus (P), which results in excessive plant (principally algae) growth and decay.

Organophosphates: Pesticides that contain phosphorus; short-lived, but some can be toxic when first applied.

When the addition of nutrients, such as nitrogen and phosphorus, from sewage effluent or agricultural runoff to surface water, greatly increases algal growth.
Erosion ...

Any treatment of sewage that goes beyond the secondary or biological water treatment stage and includes the removal of nutrients such as phosphorus and nitrogen and a high percentage of suspended solids. (See primary, secondary treatment.)
Advection ...

The addition of nutrients (e.g., nitrogen, phosphorus, carbon compounds) from sewage effluent or agricultural runoff to surface water, greatly increases the growth potential for algae and other aquatic plants. However, too much can be harmful.

Nutrient- Any substance assimilated by living things that promotes growth. The term is generally applied to nitrogen and phosphorus in wastewater, but is also applied to other essential and trace elements.

Using reclaimed water has many benefits. It conserves drinking water, is less expensive, and contains higher levels of nitrogen and phosphorus, which help fertilize plants.

Advanced wastewater treatment The removal of any dissolved or suspended contaminants beyond secondary treatment, often this is the removal of the nutrients nitrogen and/or phosphorus.

by development of an environment rich in nutrients and consequent proliferous plant production. Man-made eutrophication of inland water courses and shallow coastal waters is caused by excessive discharge of nutrients, especially phosphorus (P) and ...

During the later stages of eutrophication the water body is choked by abundant plant life due to higher levels of nutritive compounds such as nitrogen and phosphorus. Human activities can accelerate the process.

Central nervous system effects (including transient effects on mood or performance and pre-senile dementia such as Alzheimer's disease).
Peripheral nervous system effects (such as the inhibitory effects of organophosphorus compounds on synaptic ...

Bodies of water naturally contain nutrients such as phosphorus and nitrogen which are essential to plant growth.
