Environmental Hazards

When a toxin is introduced to a food chain, the negative affect will get worse as you go up trophic levels. (mice affected a little, hawks affected a lot). This describes...

• Biomagnification
• Eutrophication
• Bioremediation
• Overexploitation

DDT is a pesticide that kills mosquitoes. If a small amount gets into the water it will bioaccumulate.  This will result in

• small fish have a larger concentration of DDT than large fish
• large fish having a larger concentration of DDT than small fish
• water having a larger concentration of DDT than the fish that live in the water

What are some examples of social hazards?

• Smoking
• Drugs
• Overeating
• All of the above

The process of measuring the chance that an environmental hazard will cause harm is called 

• toxicology
• epidemiology
• dose-response relationship 
• risk assessment

Living next to a factory that pollutes the air and smoking cigarettes are both examples of _________________ hazards.

• biological
• physical
• social
• chemical

Viruses, bacteria, and other organisms in the environment that harm human health are classified as

• biological hazards
• social hazards
• chemical hazards
• physical hazards

Environmental hazards that result from where we live, our jobs, or our lifestyle choices are called

• physical hazards
• chemical hazards
• biological hazards
• social hazards

A substances' toxicity depends not just on what it is, but also

• on whether it was produced naturally or by people.
• what its scientific name is.
• how much of it a person is exposed to.
• where it is found in the environment.

The four main categories of environmental hazards are

• biological, social, human, and disease
• chemical, biological, allergen, and pollution
• physical, emotional, biological and biomagnified
• chemical, biological, social, and physical

Toxicology deals primarily with what types of hazards? 

• biological and social 
• both chemical and physical 
• Option 3  human-made 
• natural disasters
