Previous Year Question
In India, the use of carbofuran, methyl parathion, phorate and triazophos is viewed with apprehension. These chemicals are used as
pesticides in agriculture
preservatives in processed foods
fruit-ripening agents
moisturising agents in cosmetics
Correct Answer: A
Detailed Solution
Carbofuran, methyl parathion, phorate and triazophos are pesticides used to control insects in agriculture.
They are mainly insecticides and have been used to control pests on different crops.
Carbofuran is a carbamate pesticide.
Methyl parathion, phorate and triazophos are organophosphate pesticides.
These chemicals control insects by interfering with the normal functioning of their nervous systems.
Carbamate and organophosphate pesticides can inhibit the activity of the acetylcholinesterase enzyme.
Excessive or improper exposure may cause headaches, dizziness, vomiting, breathing difficulties and severe neurological effects in humans.
Agricultural workers may face a particular risk of exposure while mixing, spraying and cleaning equipment.
Residues of these pesticides may contaminate soil and water.
They may also harm birds, pollinators, aquatic organisms and other non-target species.
Their toxicity and environmental impacts cause their use to be viewed with apprehension.
Pesticides must be used according to the approved crop, prescribed dose, waiting period and safety instructions.
Personal protective equipment and safe storage reduce the risk of accidental exposure and poisoning.
Integrated Pest Management combines biological control, crop rotation and need-based chemical use to reduce dependence on pesticides.
These chemicals are not food preservatives, fruit-ripening agents or moisturising substances used in cosmetics.
