What are the harmful effects of pesticides?
Pesticides can cause short-term adverse health effects, called acute effects, as well as chronic adverse effects that can occur months or years after exposure.
Examples of acute health effects include stinging eyes, rashes, blisters, blindness, nausea, dizziness, diarrhea and death..
How can we control pesticide pollution?
Substitute non-resistant plants with pest-resistant ones. Reduce the need for pesticides by using substitutes such as biological control of insects or natural predators which are harmless to the crop. In cases of limited pest infestation, traps or manual removal could substitute for pesticides.
What are the 4 types of pesticides?
Pesticides can be grouped according to the types of pests which they kill:Insecticides – insects.Herbicides – plants.Rodenticides – rodents (rats and mice)Bactericides – bacteria.Fungicides – fungi.Larvicides – larvae.
How long do pesticides stay in the environment?
These are low (less than 16 day half-life), moderate (16 to 59 days), and high (over 60 days). Pesticides with shorter half-lives tend to build up less because they are much less likely to persist in the environment. In contrast, pesticides with longer half-lives are more likely to build up after repeated applications.
What are the most harmful pesticides?
Fungicides were the most toxic from concentrations 300–600 times lower than agricultural dilutions, followed by herbicides and then insecticides, with very similar profiles in all cell types. Despite its relatively benign reputation, Roundup was among the most toxic herbicides and insecticides tested.
What causes pesticide pollution?
Another factor affecting pesticide pollution of water is rainfall, as high levels of rainfall increase the risk of pesticides contaminating water. Movement into bodies of water occurs when runoff, after rainfall, moves through areas that have been sprayed with pesticides.
