Explain the concept of bioaccumulation and its relevance to soil pollutants.

• Bioaccumulation is the process of reducing pollutants in living organisms, making them less harmful to the environment.

• Bioaccumulation refers to the gradual build-up of substances, such as pollutants, in living organisms, and it is relevant to soil pollutants as they can be absorbed by plants and accumulate in the tissues of animals, posing health and ecological risks.

• Soil pollutants do not pose any risk of bioaccumulation in living organisms.

• Bioaccumulation only occurs in water bodies and has no relevance to soil pollutants.

Discuss the role of microorganisms in soil remediation.

• Microorganisms have no impact on soil remediation

• Microorganisms break down pollutants and contaminants in soil through biodegradation and bioremediation.

• Microorganisms release more pollutants into the soil

• Microorganisms contribute to soil pollution

What are the key lessons learned from the Love Canal tragedy in terms of environmental policy and public health protection?

• Loose environmental regulations, burying hazardous waste in the ground, and excluding community involvement

• Strict environmental regulations, proper disposal of hazardous waste, and community involvement

• Relaxing environmental regulations, improper disposal of hazardous waste, and ignoring community involvement

• No need for environmental regulations, dumping hazardous waste anywhere, and excluding community involvement

Which Malaysian agency is primarily responsible for managing and enforcing soil pollution regulations?

• Malaysian Agricultural Research and Development Institute (MARDI)

• Department of Environment (DOE)
