change of gases, burning fuels.

One of the main

ingredients in the

formation of ground-

level ozone and acid rain.

Sulfur dioxide SO2 gas

Crude oil, metals ( aluminum, copper,

zinc, lead, iron)

Refineries, cement manufacturers,

metal processing facilities.

Contributes to acid rain and acidic

streams.

Lead Metal found naturally in the environment.

Motor vehicles, industrial sources.

Ozone O3 Gas

Created by nitrogen oxides and volatile

organic compounds in the presence of

sunlight.

Bad at ground level

Effects Ecosystems
