Environmental Health The air we breathe; the water we drink; the complex interactions between human genetics and our surroundings. How do the built and natural environments influence our health and how can we reduce risk factors? These environmental risk factors can cause diseases such as asthma, cancer, and food poisoning. Specialists from chemistry, toxicology, engineering, and other disciplines combine their expertise to answer these important questions. Environmental health studies the impact of our surroundings on our health. Because environmental health is so broad in scope, it is often broken down in academic and professional settings in areas of contact and medians. These areas are: air quality food protection radiation protection solid waste management hazardous waste management water quality noise control environmental control of recreational areas housing quality vector control
