Fertilizers/pesticides

Contamination of waters with ai senic occurs as a result of a number of industrial activities such as treatment of industrial wastes, fertilizers, pesticides production, mining, metal smelting etc. and natural processes (e.g. weathering of minerals, volcanic and biological activities). [Pg.208]

The preparation of soils for crops, planting, and tilling raises dust as a fugitive emission. Such operations are shll exempt from air pollution regulations in most parts of the world. The application of fertilizers, pesticides, and herbicides is also exempt from air pollution regulations, but other regulations may cover the drift of these materials or runoff into surface waters. This is particularly true of the materials are hazardous or toxic. [Pg.509]

As we moved away from natural and manual inputs to produce crops, other inputs of machinery, fertilizer, pesticides, herbicides and fuel, many of a chemical nature, commercial or cultural energy was used as a replacement. The commercial or cultural energy has come primarily from a fossil fuel base. The approximate amount of energy to provide for these inputs is given in Table I. [Pg.328]

Established in 1894, AOAC International is an independent association of scientists and organizations in the public and private sectors devoted to promoting methods validation and quality measurements in the analytical sciences. AOAC has a mission to ensure the development, testing, validation, and publication of reliable chemical and biological methods of analysis for foods, drugs, feed-stuffs, fertilizers, pesticides, water, forensic materials and other substances affecting public health and safety and the environment. [Pg.267]

Isocyanates are important chemical feedstock for the manufacture of fertilizers, pesticides, and various forms of polyurethane (1-4). The current isocyanate synthesis process involves phosgenation of amines. [Pg.471]

Agricultural fertilizers, pesticides, and fungicides (Nriagu 1979c Thornton 1979 Ma 1984 ATSDR 1990 Roncero et al. 1992 Alva et al. 1995). [Pg.129]

Other chemical products (SICs 284, 285, 287, and 289) consist of some 6,175 corporations whose primary business is the manufacturing and marketing of soaps and detergents surfactants specialty cleaning, polishing, and sanitary preparations perfumes, cosmetics, and other toilet preparations paints, varnishes, enamels, and other allied products fertilizers, pesticides, and other agricultural chemicals and adhesives and sealants, explosives, printing ink, and other specialty chemicals and chemical preparations. [Pg.50]

Nitrates, produced from ammonia or urea, include a variety of nitrogen-based compounds used to make fertilizers, pesticides, and explosives, and they are highly... [Pg.65]

Phosphorus in the subsurface originates from a natural parent material or anthropogenic application on land surface (e.g., fertilizers, pesticides, surfactant products, sludge, and effluents). This element may be found in inorganic or organic forms, which are in a dynamic equihbrium with dissolved P in the subsurface liquid phase. [Pg.313]

The B S Research, Inc., B S Achieve-B S Industrial technology uses microorganisms (B S Industrial) with emulsifier and nutrients (B S Achieve) to treat contaminated soil and water. According to the technology developer, the technology degrades hydrocarbons, chlorinated solvents, polychlorinated biphenyls (PCBs), fertilizers, pesticides, and other hazardous organic compounds. [Pg.383]

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). [Pg.714]

Ag-Chcmicals Fertilizers, Pesticides, Herbicides, Insecticides, Soil Conditioners, Aglime, Dolomite, Trace Minerals, N-P-K raw Materials... [Pg.359]

Water Over-exploitation of groundwater has led to a decrease in the level of groundwater in many agricultural regions of Asia, North Africa, the Middle East, and the U.S.A. The impact of sewage, fertilizers, pesticides, oil product remains, heavy metals, stable phosphor-organic compounds and radioactive substances has led to a substantial decrease of groundwater quality. [Pg.105]

Kinetics of reactions in soil and aquatic environments is a topic that is of extreme importance and interest. Most of the chemical processes that occur in these systems are dynamic, and a knowledge of the mechanisms and kinetics of these reactions is fundamental. Moreover, to properly understand the fate of applied fertilizers, pesticides, and organic pollutants in soils with time, and to thus improve nutrient availability and the quality of our groundwater, one must study kinetics. [Pg.219]

Industrial catalysts have made it possible to utilize and enjoy many new products in the areas of plastics, transportation, clothing, detergents, food supply, and construction. The production of most polymers involves catalysis either in polymerization or in monomer synthesis. Improved fuels, tires, and construction materials have revolutionized the transportation industry in this century. Synthetic fibers are widely used in clothing and carpets. Biodegradable detergents are available for inexpensive cleaning. Fertilizers, pesticides, and herbicides have been used to increase crop yields to feed a growing world population. [Pg.95]
