The most commonly observed health effects in people exposed to extremely high levels of PCBs are skin conditions, such as chloracne and rashes, but these were known to be symptoms of acute systemic poisoning dating back to 1922.
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 ...
Toxic chemicals called PFAS are in pesticides sprayed on food and included in pet flea treatments and home bug repellants, a new study found. Toxic ‘forever chemicals’ found in pesticides used ...
PCBs are toxic to fish at high doses, and associated with spawning failure at low doses. Human exposure occurs through food, and is associated with reproductive failure and immune suppression. Immediate effects of PCB exposure include pigmentation of nails and mucous membranes and swelling of the eyelids, along with fatigue, nausea, and vomiting.
Two serious food contamination accidents were caused by PCB oils used in heat exchangers. [1] The PCB oil leaked to rice bran oil consumed by thousands of people in Japan (Yusho disease 1968) and Taiwan (Yu-cheng disease 1979). The toxic effects have been attributed to dioxin-like PCBs and PCDFs.
The third type of poisoning is a long-term low-level exposure, which individuals are exposed to from sources such as pesticide residues in food as well as contact with pesticide residues in the air, water, soil, sediment, food materials, plants and animals. [1] [2] [3] [4]
Dioxins enter the general population almost exclusively from ingestion of food, specifically through the consumption of fish, meat, and dairy products since dioxins are fat-soluble and readily climb the food chain. [22] [23] Children are passed substantial body burdens by their mothers, and breastfeeding increases the child's body burden. [24]
Aldicarb is a carbamate insecticide which is the active substance in the pesticide Temik. It is effective against thrips, aphids, spider mites, lygus, fleahoppers, and leafminers, but is primarily used as a nematicide. [2] Aldicarb is a cholinesterase inhibitor which prevents the breakdown of acetylcholine in the synapse.
