Sulfur Dioxide(SO2)
The release of SO2 to the atmosphere is the primary cause of acid rain in the world.
Fossil fuel combustion at electric power-generating plants accounts for about70% of
the emissions.
Coal, Oil, and all other fossil fuels naturally
contain some sulfur.
Volcanic eruptions are another more localized natural source of SO2
SO2 + OH. HSO3.

1. 대기오염
우리가 살고 있는 지구에는 대기라는 층이있다 우리가 숨쉬고 활동할 수 있는 것은 대기가 존재하기 때문이다 그러한 대기를 살리고 보존하기 위해 우리 5조는 대기 오염과 그방책에대해 애기해 보기로 했다.우성 대기 오염의 정의에 대해서 알아보도록 한다

Several countries including Canada, Finland, Norway, and Sweden agreed with the regulations and reduction of the output of CFCs. Conversely, the EU didn’t consent to them as the biggest producing group. Some were reluctant to participate in this move, but it widely turned out to be that if a country disregards the protection of the ozone l

The clothes and skin of animal handlers such as farmers, standing water, and uncooked food scraps and feed supplements containing infected animal products can harbor the virus as well. Cows can also catch FMD from the semen of infected bulls. Control measures include quarantine and destruction of infected livest
