Diazinon
Diazinon is an organophosphate insecticide used to control a wide variety of insect pests. It works by inhibiting acetylcholinesterase, an enzyme crucial for nerve function in insects and other organisms. This inhibition leads to an accumulation of acetylcholine at nerve synapses, causing overstimulation, paralysis, and ultimately, death.
Diazinon has been used extensively in agriculture, horticulture, and residential pest control. Common applications have included controlling insects on crops such as fruits, vegetables, and field crops, as well as in gardens, lawns, and homes. It has been formulated into various products, including granules, liquids, and dusts.
Due to concerns regarding its toxicity to humans, wildlife, and the environment, particularly its impact on aquatic organisms and birds, diazinon has been subject to increasing regulation and restrictions in many countries, including the United States and the European Union. Certain uses have been phased out, and alternative pest control methods are often recommended.
Exposure to diazinon can occur through inhalation, ingestion, or skin absorption. Symptoms of exposure can range from mild effects such as nausea, dizziness, and sweating, to more severe effects like respiratory distress, seizures, and coma. Proper handling, storage, and disposal are essential to minimize risks associated with its use.
Environmental persistence varies depending on factors such as soil type, temperature, and moisture. Diazinon can contaminate soil and water, posing risks to non-target organisms. Mitigation strategies include following label instructions carefully and considering integrated pest management (IPM) approaches to reduce reliance on chemical insecticides.
