We face countless environmental hazards every day. To better understand them, we can think of them as falling into four categories: physical, chemical, biological, and cultural. Physical hazards are physical processes that occur naturally in the environment.

There are four primary categories of food safety hazards to consider: biological, chemical, physical, and allergenic. Understanding the risks associated with each can dramatically reduce the potential of a foodborne illness.

Though there are many different chemicals in air pollution, this lesson will focus on the six most common types: lead, nitrogen oxide, ozone, particulate matter, carbon dioxide, and sulfur dioxides. These can be in the form of solids, liquids, or gases.

There are two broad types of hazards associated with hazardous chemicals, which may present an immediate or long-term injury or illness to people. These are health hazards and physiochemical hazards. Many chemicals have both health and physicochemical hazards.

Environmental hazards increase the risk of cancer, heart disease, asthma, and many other illnesses. These hazards can be physical, such as pollution, toxic chemicals, and food contaminants, or they can be social, such as dangerous work, poor housing conditions, urban sprawl, and poverty.

The four main types of sustainability are human, social, eco- nomic and environmental. These are defined and contrasted in Tables 1–4. It is important to specify which type of sustainability one is dealing with as they are all so different and should not be fused together, although some overlap to a certain extent.
