Source:
Env. Concern:

Back 9

Chlorofluorocarbons

Health Concern: Causes cataracts and skin cancer
Source: Aerosols
Env. Concern: Eats away at ozone and causes holes

Front 10

Hg

Health Concern:
Source:
Env. Concern:

Back 10

Mercury

Health Concern: Reductions in motor skills and dulled senses of touch, taste, and sight.

Source: A big source of mercury into our air is from facilities and vehicles that burn fossil fuel. it can then be carried airborne hundreds of miles before falling back to earth through rain, snow, and dry depositions. which it then ends up in our rivers and lakes and accumulate in the fish that we consume.

Env. Concern: Ultimately, mercury ends up in the sediments, fish and wildlife, or evades back to the atmosphere by volatilization. Mercury is affecting our food life and water life as well as the air we breathe. Which is dangerous for everyone.

Front 11

What are the two classes of toxic chemicals? Give examples of each.

Back 11

Heavy metals: lead, mercury, arsenic, tin, copper, zinc. These are water soluble

Chemical compounds: pesticides, cleaning products, chemical sprays. can be synthetic or organic. These cause environmental damage like bioaccumulation and biomagnification
