Which of the following is a hazard of pesticides?

• A. Human poisoning
• B. Extended shelf life
• C. Improved crop coloration
• D. Increased pollinator activity

Answer: (A)

Pesticides are toxic chemicals, so the most immediate hazard they pose is to human health through exposure. When people inhale, touch, or ingest pesticide residues—during mixing, loading, applying, or just being in a treated area—they can develop poisoning. Symptoms vary by product but can include dizziness, headaches, nausea, sweating, or more serious effects like respiratory distress or nerve system issues with certain types of pesticides. This is why proper training, following the label, using personal protective equipment, and keeping people and pets out of treated zones are essential safety steps.

The other outcomes described are not hazards to people. Extended shelf life is a product quality attribute, not a health risk. Improved crop coloration and increased pollinator activity are potential agricultural effects or benefits, not dangers to human health.
