What should be done with surplus pesticides or containers that have inorganic chemicals like mercury or lead?

Surplus pesticides or containers that contain inorganic chemicals such as mercury or lead must be handled with extreme caution due to their hazardous nature. These substances pose significant environmental and health risks if not disposed of properly.

The correct approach is to ensure that such materials are neither incinerated nor buried. Incineration of inorganic chemicals can release toxic emissions into the atmosphere, potentially harming air quality and contributing to environmental contamination. Similarly, burying these hazardous materials can lead to leachate, which can contaminate soil and groundwater, posing serious risks to ecosystems and human health.

Proper disposal often involves contacting local waste management authorities or hazardous waste programs that can provide guidance on safe disposal practices. This ensures that the materials are processed in a manner that mitigates any potential hazards associated with their toxic properties. Proper disposal is critical for protecting public health and the environment.
