How do pesticides affect the environment?

    Pesticides can kill beneficial soil bacteria, earthworms, snails, birds, frogs, fish and other valuable species. Water in urban rivers, creeks and ponds have also contained pesticides that came from lawn care items. This leads to the water being dangerous to mess with.

    Pesticides, along with killing valuable species, can get into the water supply. By spraying too much pesticides, the runoff can leech into the ground water or into nearby streams and other water supplies. Pesticides can be very dangerous if ingested and each animal higher on the food chain gets a bigger percentage of the pesticide (bioaccumulation).

    In addition to killing valuable species and affecting the water supply, there is some research which indicated pesticides contribute to air pollution. For instance, in an EPA study (first link below), there existed a higher concentration of pesticides within people’s homes than “can be explained by recent pesticide use in those households” with other possible sources including “contaminated soil or dust that floats or is tracked in from outside”. 

    Pesticides can also be sources of volatile organic compounds (VOCs), which can contribute to ground-level ozone. Ground-level ozone can be “harmful to human health and vegetation when present at high enough concentrations” (see the second link below).
