Environmental Pollutants refers to substances or agents that contaminate air, water, soil, or other natural systems and may affect ecosystems or human health. This skill involves understanding the sources, properties, movement, and impacts of these pollutants in work settings such as environmental monitoring, compliance, risk assessment, and remediation planning. It is applied to identify pollutant hazards, support control measures, and inform decisions that reduce environmental contamination.

Environmental Science refers to the study of the interactions between the physical, chemical, and biological components of the environment and the impact of human activities on these systems. This skill encompasses the analysis of environmental data, assessment of ecological health, and development of strategies for sustainable resource management. Knowledge of Environmental Science is used to address environmental challenges, inform policy decisions, and promote conservation efforts through research and interdisciplinary collaboration.

Environmental Toxicology refers to the study of the effects of chemical pollutants on the environment and human health. This skill encompasses the assessment of toxic substances, their sources, and their impact on ecosystems and organisms. Knowledge of Environmental Toxicology is used to evaluate risks, develop regulations, and implement strategies for pollution control and remediation to protect environmental and public health.

The Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) is a federal law that regulates the manufacture, distribution, sale, and use of pesticides. It requires companies to register their pesticides with the Environmental Protection Agency (EPA) and meet certain safety standards. FIFRA also establishes rules for pesticide labeling, packaging, and storage. Compliance with FIFRA regulations is important to protect human health and the environment. Understanding and navigating FIFRA regulations requires specialized knowledge and expertise.

Human Health Risk Assessment refers to the systematic process of evaluating the potential adverse health effects resulting from exposure to hazardous substances or situations. This skill involves identifying hazards, assessing exposure levels, and characterizing risks to inform decision-making and public health policies. Knowledge of Human Health Risk Assessment is used to prioritize health interventions, guide regulatory actions, and develop strategies for risk management in various environments, including occupational, environmental, and community settings.
