What is the purpose of Environmental Risk Assessment?

The purpose of Environmental Risk Assessment is primarily to estimate the impact of hazardous substances on the environment. This process involves identifying potential hazards, assessing their likelihood of occurrence, and evaluating the potential consequences of exposure to these substances. It helps in understanding how different pollutants can affect ecosystems, wildlife, human health, and the environment at large, allowing for informed decision-making regarding environmental management and regulatory measures.

In the context of risk assessment, it is critical to analyze various factors, such as the toxicity of the substances, the pathways through which they may spread, and the vulnerability of the ecosystems or populations affected. This comprehensive understanding helps to prioritize risks and allocate resources effectively for mitigation efforts.

Other options, while related to environmental science, do not specifically address the primary aims of Environmental Risk Assessment. Developing new environmental policies may be an outcome of risk assessment findings, but it isn't the direct purpose. Assessing wildlife populations focuses on biodiversity and conservation rather than the specific impacts of hazardous substances. Evaluating the sustainability of energy sources addresses a broader aspect of environmental stewardship but again diverges from the focused goal of estimating risks posed by specific harmful agents.
