Organophosphates are NOT much more harmful to man.

• A. Not sure
• B. True
• C. False
• D. Depends on exposure

Answer: (B)

The key idea here is that harm from pesticides depends on exposure, not just the chemical’s inherent toxicity. Organophosphates inhibit acetylcholinesterase, which can cause serious, life‑threatening effects in people if exposure is high or occurs via dangerous routes (inhalation, dermal contact, or ingestion). However, the level of risk to humans is largely determined by dose and exposure conditions. When organophosphates are used according to label directions, with proper protective equipment, ventilation, and safe handling, the actual risk to people is managed and may not be much higher than that of many other pesticides. That context—controlled exposure and safety measures—explains why the statement can be considered true in a safety/occupational context.
