These chemicals not only can kill wild animals, but can also disrupt hormones in animals, affecting behavior and the ability to reproduce. ... Some persistent pesticides can build up in the bodies of animals, including humans. The natural enemies of pest insects can also be killed by pesticides.

What pesticides are most likely to cause harm to wildlife?

Malathion, an insecticide registered for use in the US since 1956, is likely to cause harm to 97% of the 1,782 mammals, birds, fish, reptiles and plants listed under the Endangered Species Act. Malathion is commonly used to treat fruit, vegetables and plants for pests, as well as on pets to remove ticks.

What happens when pesticides are sprayed on crops?

Pesticides can contaminate soil, water, turf, and other vegetation. In addition to killing insects or weeds, pesticides can be toxic to a host of other organisms including birds, fish, beneficial insects, and non-target plants.

Who is most affected by pesticides?

Some people are more vulnerable than others to pesticide impacts. For example, infants and young children are known to be more susceptible than adults to the toxic effects of pesticides. Farm workers and pesticide applicators are also more vulnerable because they receive greater exposures.

How herbicides affect animals?

When birds eat worms and insects, pesticide residues move up through the food chain. When herbicides kill plants regarded as weeds they remove vital sources of food and shelter for wild species, adding to pressure on them to relocate, alter their diet, or starve.

How do pesticides affect plants and animals?

Pesticide exposure can be linked to cancer, endocrine disruption, reproductive effects, neurotoxicity, kidney and liver damage, birth defects, and developmental changes in a wide range of species. Exposure to pesticides can also alter an organism's behavior, impacting its ability to survive.

What animals affect pesticides?

As vertebrate species, reptiles and amphibians are also at risk of pesticides. Though less is known about the effects of pesticides on reptiles and amphibians, these animals have been known to fall victim to pesticide poisoning. Blue-tongue lizards, for example, often consume rat bait and die of internal bleeding.

Why farming chemicals are bad?

Conventional agricultural practices are polluting soils, rivers and oceans with large amounts of harmful agricultural chemicals. ... Such chemicals are used to obtain maximum yields, but when the algae die the bacteria uses up all of the oxygen in decomposing it, thus creating an oxygen dead (or hypoxic) zone[sc:3].

How do pesticides affect our food?

Very small amounts of pesticides that may remain in or on fruits, vegetables, grains, and other foods decrease considerably as crops are harvested, transported, exposed to light, washed, prepared and cooked. The presence of a detectible pesticide residue does not mean the residue is at an unsafe level.

How do pesticides affect plants?

Pesticides can be absorbed by plants through the leaves and roots. Pesticides that are taken up by plants can move (translocate) to other parts of the plant. Herbicides that are taken up by the plant (systemic herbicides) often are designed to interfere with the plants development by mimicking plant hormones.

How do pesticides affect groundwater?

Pesticides reach groundwater through runoff and leaching. ... Leaching pesticides can move with the infiltrating water through the soil profile to the water table. The closer the water table is to the surface, the greater is the risk that it may become contaminated.

Are pesticides in food harmful?

Coming into contact with large amounts of pesticides can be harmful. Although most produce contains some level of pesticide residue, food testing ensures that the levels of pesticides are low enough to not pose a risk to human health.

What are the harmful effects of pesticides on the environment?

Pesticides secrete into soils and groundwater which can end up in drinking water, and pesticide spray can drift and pollute the air. The effects of pesticides on human health depend on the toxicity of the chemical and the length and magnitude of exposure.

What is the useful effect of insecticide?

Humans have attained important benefits from many uses of insecticides, including: (1) increased yields of crops because of protection from defoliation and diseases; (2) prevention of much spoilage of stored foods; and (3) prevention of certain diseases, which conserves health and has saved the lives of millions of ...
