1997). The impact on the non-target organisms depends on the pesticide’s chemical properties such as its toxicity, solubility, mobility and persistence. The pesticide’s environmental impact is also dependent on the method, quantity and time of application, as well as, the nature of the surrounding environment.

The decisive factor for assessing the environmental impact of pesticides is not so much the amount of pesticide used, but rather the potency or potency equivalence of the effect in question. When applied in low doses, today’s highly potent pesticides may be just as environmentally hazardous as previous generations of pesticides for which ...

A pesticide is any substance used to kill, repel, or control certain forms of plant or animal life that are considered to be pests. Pesticides include herbicides for destroying weeds and other unwanted vegetation, insecticides for controlling a wide variety of insects, fungicides used to prevent the growth of molds and mildew, disinfectants for preventing the spread of bacteria, and compounds ...

What Is Chemical Pollution | Environmental Pollution Centers

Examples of Chemical Pollutants. Chemical pollutants mostly result from various human activities like the manufacturing, handling, storing, and disposing of chemicals. These occur in industrial places and activities such as oil refineries, coal power plants, construction, mining & smelting, transportation, agricultural use of pesticides and insecticides, as well as household activities.

A probabilistic analysis reveals fundamental limitations ...

Comparing risks among pesticides has substantial utility for decision makers. However, if rating schemes to compare risks are to be used, they must be conceptually and mathematically sound. We address limitations with pesticide risk rating schemes by examining in particular the Environmental Impact Quotient (EIQ) using, for the first time, a probabilistic analytic technique.

Environmental Effects of Lawn Treatment

Pesticide leaching depends, in part, on the chemical and physical properties of the pesticide. For example, a pesticide held strongly to soil particles is less likely to leach. Solubility is another factor because a pesticide that dissolves in water can move with water in the soil.

Naphthalene - National Pesticide Information Center

The half-life of naphthalene in the environment may range from less than one day in air to over 80 days in soil. Can naphthalene affect birds, fish, or other wildlife? Naphthalene was considered moderately toxic to several species of fish, water fleas, and Pacific oysters.

Four herbicides and two insecticides were linked to increased risk of renal cell carcinoma in people licensed to apply pesticides, according to authors of a study published June 12 in Environmental Health Perspectives.The study is the largest and most comprehensive investigation of pesticide use and kidney cancer, said scientists at NIEHS and the National Cancer Institute (NCI).

Fungicides, Herbicides, and Insecticides

Pesticide residues on plants degrade to harmless byproducts over time. Toxicity varies among pesticide products, however, as does the amount of time necessary for degradation. The toxicity of pesticide residues has been tested and, in some cases, restrictions have been placed on the use of a product.

The Impact of Water Quality on Pesticide Performance

Pesticide Performance Since water normally is used to deliver the chemical to the tar-get pest, it should be considered the foundation for the applica-tion process. Whether the water is from a well or from a lake, stream, or pond, it may be the deciding factor between ineffective and op-timum product performance. Turbidity. Suspended, posi-

Pesticide residues in food - World Health Organization

The toxicity of a pesticide depends on its function and other factors. For example, insecticides tend to be more toxic to humans than herbicides. The same chemical can have different effects at different doses (how much of the chemical a person is exposed to). ... Global impact.
