The effects of pesticides on human health depend on the toxicity of the chemical and the length and magnitude of exposure. [97] Farm workers and their families experience the greatest exposure to agricultural pesticides through direct contact. Every human contains pesticides in their fat cells.
However, the effects are tested a single pesticide at a time and there is little information on the possible synergistic effects of exposure to multiple pesticide traces in the air, food and water on human health. [16] While pesticide use is commonly associated with agriculture, pesticides are also used as part of public health interventions to ...
Small pesticide exposures have been shown to have an impact on young children's neurological and behavioral development. [47] Researchers have studied the effects of pesticides on children as opposed to adults, finding children's immature organs and bodies are more susceptible to health effects. [47]
The word pesticide derives from the Latin pestis (plague) and caedere (kill). [5]The Food and Agriculture Organization (FAO) has defined pesticide as: . any substance or mixture of substances intended for preventing, destroying, or controlling any pest, including vectors of human or animal disease, unwanted species of plants or animals, causing harm during or otherwise interfering with the ...
Carson accuses the chemical industry of intentionally spreading disinformation and public officials of accepting industry claims uncritically. Most of the book is devoted to pesticides' effects on natural ecosystems, but four chapters detail cases of human pesticide poisoning, cancer, and other illnesses attributed to pesticides. [27]
Health consequences from exposure to soil contamination vary greatly depending on pollutant type, the pathway of attack, and the vulnerability of the exposed population. Researchers suggest that pesticides and heavy metals in soil may harm cardiovascular health, including inflammation and change in the body's internal clock. [17]
Environmental epidemiology is a branch of epidemiology concerned with determining how environmental exposures impact human health. [1] This field seeks to understand how various external risk factors may predispose to or protect against disease, illness, injury, developmental abnormalities, or death.
Where high annual rates of phosphorus fertilizer are used, this can result in uranium-238 concentrations in soils and drainage waters that are several times greater than are normally present. However, the impact of these increases on the risk to human health from radionuclide contamination of foods is very small (less than 0.05 mSv/y).
