BIOXII16: ENVIRONMENTAL ISSUES
345250 atoms added to the stratosphere by have
1 Permanent and continuous effect on levels.
2 Temporary and discontinuous effect in levels.
3 Temporary and continuing effects on Ozone levels.
4 Permanent and continuing effects on Ozone levels.
Explanation:
atoms added by CFCs to the stratosphere, have permanent and continuing effects on Ozone levels, because atoms are not consumed in the ozone degradation reaction as they act as catalyst.
