1. Uses:

• Atrazine is a widely used herbicide, primarily for controlling broadleaf and grassy weeds in corn, sugarcane, sorghum, and other crops.
• It works by interfering with photosynthesis in plants, ultimately killing them.

2. Human health hazards:

• Potential endocrine disruptor, meaning it may interfere with hormonal systems.
• Classified as “possibly carcinogenic to humans” by the International Agency for Research on Cancer (IARC).
• Linked to birth defects, low birth weight, and other developmental problems in some studies.
• May cause skin irritation and eye damage.

3. Environmental hazards:

• Highly persistent in the environment, meaning it breaks down slowly and can accumulate in soil and water.
• Toxic to aquatic life, including fish, amphibians, and invertebrates.
• Can contaminate drinking water sources.

4. Potential safer alternatives:

• Mechanical weed control: Tilling and other methods to physically remove weeds.
• Mulch: Suppresses weed growth by blocking sunlight and preventing germination.
• Cover crops: Fast-growing plants planted between cash crops to compete with weeds for resources.
• Bioherbicides: Naturally occurring substances that kill specific weeds.
• Herbicides with lower toxicity and environmental impact: Several newer herbicides are being developed with improved safety profiles.
