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 ...

The environmental effects of pesticides describe the broad series of consequences of using pesticides. The unintended consequences of pesticides is ...
Bacillus thuringiensis (or Bt) is a gram-positive, soil-dwelling bacterium, the most commonly used biological pesticide worldwide. B. thuringiensis also occurs naturally in the gut of caterpillars of various types of moths and butterflies , as well on leaf surfaces, aquatic environments, animal feces, insect-rich environments, flour mills and ...
Pesticides tracked into the home from family members increase the risk of exposure. Toxic residue in food may contribute to a child's exposure. [98] Epidemiological studies have reported adverse effects of certain pesticides at current levels of exposure on children's cognitive development. [99] The chemicals can bioaccumulate in the body over ...
The effects of pesticides at high concentrations on human health is a thus a matter of much study, resulting in many publications on the toxicology of pesticides. However the maximum residue limits of pesticides in food are low, and are carefully set by the authorities to ensure, to their best judgement, no health impacts.
Farmers and everyone in surrounding areas of pesticide poisoning are exposed and at risk of all the long term effects. [45] The neurotoxicity of certain pesticides has been implicated as a potential contributing factor to the development of neurodegenerative diseases, raising concerns about their long-term impact on human health.
