Definition: Dieldrin was produced as an insecticide from the 1950s to 1970, and was widely used as pesticide for corn, cotton, and citrus crops. Dieldrin was also used for mothproofing clothes and carpets. Advantages: - (BENEFITS):Aldrin and dieldrin were mainly used as insecticides. They were applied to treat crops for protection against pests. They were also used to exterminate termites. https://www.hss.gov.nt.ca/sites/hss/files/resources/contaminants-fact-sheets-aldrin-dieldrin.pdf - for humans: EFFECTS IN HUMANS. Human poisoning from aldrin and dieldrin is characterized by major motor convulsions. Other effects include malaise, incoordination, headache, dizziness, and gastrointestinal disturbances. The seizures have developed with and without other symptoms of poisoning. https://www.ncbi.nlm.nih.gov/books/NBK217623/#:~:text=EFFECTS%20IN%20HUMANS ,without%20other%20symptoms%20of%20poisoning. - Why was it banned?: Because of concerns about damage to the environment and potentially to human health, EPA banned all uses of aldrin and dieldrin in 1974, except to control termites. In 1987, EPA banned all uses. https://volusia.floridahealth.gov/programs-and-services/environmental-health/local-inves tigations/_documents/aldrin.pdf Disadvantages - https://www.sciencedirect.com/topics/agricultural-and-biological-sciences/dieldrin General - Produced by humans, don’t occur in natural environment - Aldrin and Dieldrin = similar POPs - Applied to crops to treat from pests - Banned in several parts of world - POP levels become higher as we move up food chain (biomagnification) - Toxic to humans at high level - Exposure: eating contaminated foods, inhaling contaminated air, contact with skin - Exposure to aldrin and dieldrin at low levels over a long period of time is not a human health hazard. - Can be ingested through animals – food we eat https://www.hss.gov.nt.ca/en/services/contaminants-environnementaux/aldrin-and-dieldrin Advantages - The benefits of eating traditional foods outweigh the risks from contaminant exposure - Protection of crops Disadvantages - Bad for health, stays in food chain - Damage to environment and potentially human health - Toxicity – central nervous system, irritability, tremors, convulsions - Linked to increased risk of breast cancer https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=&ved=2ahUKEwi9uJ-skZ SCAxX63QIHHTkpABYQFnoECBIQAw&url=https%3A%2F%2Fwww.ncbi.nlm.nih.gov%2Fbook s%2FNBK217623%2F&usg=AOvVaw2jSWczELuBGoApGRRvkLqm&opi=89978449
