Effects pesticide use
Multiple kinds of studies are used to understand what levels of pesticides are harmful.
Effects of pesticides on the environment and human health
Pesticide can affect fetuses in early stages of development, in utero and even if a parent was exposed before conception. By understanding the difference in toxicity levels of pesticides, a user can minimize the potential hazard by selecting the pesticide with the lowest toxicity that will control the pest. Check equipment for leaks and malfunctions before use to minimize the potential for accidental spills. Because there are many kinds of potential pests, there are several kinds of pesticides. The focus is broader than on a specific pest, considering a range of pest control alternatives. Want to support us in our work to replace pesticides with safer alternatives? This list is not comprehensive, but it illustrates two important concepts. The chronic toxicity of a pesticide is more difficult than acute toxicity to determine through laboratory analysis. While pyrethroids are among the least toxic pesticides to humans, they are an excitatory nerve poison and known carcinogen. Rodenticides: Important for controlling destruction and contamination of crops by vermin and rodent-borne diseases. This article focuses on pesticide residues, or the pesticides found on the surface of fruits and vegetables when they are purchased as groceries.
Herbicides: Also known as weed killers, these improve crop yields. Pesticides that are classified as highly toxic Toxicity Category I on the basis of either oral, dermal, or inhalation toxicity must have the signal words DANGER and POISON printed in red with a skull and crossbones symbol prominently displayed on the front panel of the package label.
Fetal DDT exposure reduces male penis size in animals and can produce undescended testicles. Copper sulfate: Destroys fungi and some weeds. Immediate symptoms may not be severe enough to prompt an individual to seek medical attention, or a doctor might not even think to ask about pesticide exposure.
Tyrone Hayes of UC Berkeley to study the environmental impacts of atrazine. Food that is sold or donated such as food aid should comply with pesticide regulations, in particular with maximum residue limits.
In some cases, a pest insect that is controlled by a beneficial predator or parasite can flourish should an insecticide application kill both pest and beneficial populations.
