Fertilizer pollution source

Almost any chemical not arising from natural sources is a pollutant in water. Agricultural wastes from fertilizers and pesticides are the major pollution sources nationally. Fertilizers add nutrients that promote algae growth whose decay can cause the lake or river to become anaerobic through the overall reactions... 

A last application of the previous reference (Thomas et al., 2005) was the study of pollution sources of lake Brome (Southern Quebec) from its tributaries, giving useful information related to agricultural pressure (manure spreading), wastewater management (urban runoff discharges) or golf management (use of fertilizers and pesticides). 

One study compared the effects of living near a fertilizer factory on the respiratory health of 8-9-year-old children (Gomzi and Saric 1997). The study found that the air quality near a fertilizer plant was within acceptable limits for most of the measurement period, with only a few fluctuations beyond acceptable limits. While these fluctuations correlated somewhat with health parameters measured on children living nearby, the rate of respiratory disease was more influenced by indoor air pollution sources than by... 

In a fertilizer plant, the main source of potential air pollution is dusts and fiunes from spills, operating upsets, and dust emissions. It is essential that tight operating procedures be in place and that close attention be paid to constant cleanup of spills and to other housecleaning measures. 

Describe typical sources and types of air emissions resulting from fertilizer manufacturing. What are some pollution prevention practices used in this industry What are some of the emission control devices used and for what purposes ... 

Lead may also interact detrimentally with aquatic life. Once lead deposits in soil, it sticks to soil particles and is only displaced by rain water, ending up in water sources where it affects the aquatic life. Some plants accumulate Pb from both contaminated soils and water sources or more specifically water in the rhizosphere. Besides, contaminated soils are liable to remain polluted with lead this will affect soil fertility.3,4 The fact that large changes in the lead content of soil are required to produce changes in the aerial parts of the plants as compared to changes in aerial lead concentration is closely reflected in the leaf lead concentration. Accumulation of Pb in grasses remains a potential hazard to livestock.3... 

Introduction and setting The purpose of this study was to identify and quantify the sources of heavy metals, especially lead, in soils and plants of the Lower Guadiana River basin and thereby model the potential mobility of lead. Other than direct pollution from mining, the main sources of heavy metal pollution in the environment are by diffuse pollution (Callender, 2004). In agricultural areas this can include lead from the use of pesticides, fertilizers and municipal sludge (Alloway, 1985). Metals can be attached or associated with different mineral phases in the soil, this along with environmental parameters determinesthe availability to plants. 

As previously mentioned, fertilizer manufacturing may create problems within all environmental media, that is, air pollution, water pollution, and solid wastes disposal difficulties. In particular, the liquid waste effluents generated from phosphate and mixed and blend fertilizer production streams originate from a variety of sources and may be summarized [17,27] as follows (a) ammonia-bearing wastes from ammonia production (b) ammonium salts such as... 

Water pollution results from a number of sources including agricultural runoff, erosion, industrial wastes, domestic wastes, and road runoff. Water pollution can be classified as either point source or nonpoint source. Point source pollution is emitted from a specific, well-defined location such as a pipe. Nonpoint sources refer to pollutants dispersed over a wide area from many different areas. A sewer pipe would be an example of a point source and fertilizer runoff from a field would represent nonpoint source pollution. 

Potassium carbonate is used in the chemical industry as a source of inorganic potassium salts (potassium silicates, potassium bicarbonate), which are used in fertilizers, soaps, adhesives, dehydrating agents, dyes, and pharmaceuticals. Potassium carbonate used to make potassium lye produces soft soaps, which are liquids or semisolids rather than solids. Other uses of potassium carbonate includes use as a fire suppressant in extinguishers, as a C02 absorbent for chemical processes and pollution control, an antioxidant in rubber additives, and in pharmaceutical formulations. 

Pollutants derived from nonpoint sources run-off from agricultural lands (fertilizers, pesticides, humic materials), run-off from urban areas (salt, poly aromatic hydrocarbons [PAHs], asbestos), atmospheric fallout (particulates containing sulfate, nitrate, heavy metals, PAHs, and chlorinated organics). 

Eutrophication. Thus far N has been discussed in terms of its prominence as an acidic anion (i.e., as N03 ). As in terrestrial ecosystems, inorganic forms of N also act as nutrients in aquatic systems, and a possible consequence of chronic N loss from watersheds is the fertilization of lakes and streams. Establishing a link between N deposition and the eutrophication of aquatic systems depends on a determination that the productivity of the system is limited by N availability and that N deposition is a major source of N to the system. In many cases the supply of N from deposition is minor when compared to other anthropogenic sources, such as pollution from either point or nonpoint sources.
