Which is one of PBH's five areas?

• A. Agricultural Sciences
• B. Environmental Sciences
• C. Health Policy and management
• D. Biostatistics

Answer: (B)

Public health practice organizes its disciplines into five major areas, and Environmental Sciences is one of them. This area focuses on how the environment and environmental exposures—from air and water quality to housing, workplace safety, and climate-related factors—shape population health. Understanding this area helps public health professionals assess environmental risks, design interventions to reduce harmful exposures, and advocate for policies that create healthier environments for communities. While other fields like Agricultural Sciences, Biostatistics, and Health Policy and Management are important to public health, the option here aligns with the Environmental Sciences domain, which is identified as one of PBH’s five areas.
