Other agrochemicals, such as fertilizers, can also have negative effects on the environment. The negative effects of pesticides are not just in the area of application. Runoff and pesticide drift can carry pesticides into distant aquatic environments or other fields, grazing areas, human settlements and undeveloped areas.
Health effects of pesticides may be acute or delayed in those who are exposed. [1] Acute effects can include pesticide poisoning, which may be a medical emergency. [2] Strong evidence exists for other, long-term negative health outcomes from pesticide exposure including birth defects, fetal death, [3] neurodevelopmental disorder, [4] cancer, and neurologic illness including Parkinson's disease ...
Rachel Carson's 1962 environmental science book Silent Spring brought about the first major wave of public concern over the chronic effects of pesticides. Those who reside close to agriculture land are negatively impacted by pesticide drifting. [ 48 ]
It is one of the most negative effects of pesticide application. Drift can damage human health, environment, and crops. [1] [2] Together with runoff and leaching, drift is a mechanism for agricultural pollution. [3] Some drift results from contamination of sprayer tanks. [4] Farmers struggle to minimize pesticide drift and remain productive. [5]
Management practices, or ignorance of them, play a crucial role in the amount and impact of these pollutants. Management techniques range from animal management and housing to the spread of pesticides and fertilizers in global agricultural practices, which can have major environmental impacts.
Pesticide degradation is the process by which a pesticide is transformed into a benign substance that is environmentally compatible with the site to which it was applied. Globally, an estimated 1 to 2.5 million tons of active pesticide ingredients are used each year, mainly in agriculture .
Phytotoxicity describes any adverse effects on plant growth, physiology, or metabolism caused by a chemical substance, such as high levels of fertilizers, herbicides, heavy metals, or nanoparticles. [1] General phytotoxic effects include altered plant metabolism, growth inhibition, or plant death. [2]
Runoff and pesticide drift can carry pesticides into distant aquatic environments or other fields, grazing areas, human settlements and undeveloped areas. Other problems emerge from poor production, transport, storage and disposal practices. [18] Over time, repeat application of pesticides increases pest resistance, while its effects on other ...
