The ozone layer needs protection against the indiscriminate use of _.
Correct answer: B. Refrigerants and high-flying jets
- A. Fungicides, insecticides, bactericides, and medicines
- B. Refrigerants and high-flying jets
- C. Atomic explosions and industrial wastes
- D. None of these
Explanation
Many common refrigerants and aerosol propellants are chlorofluorocarbons (CFCs), which are the primary cause of ozone depletion. Additionally, the exhaust from high-flying jet aircraft can release nitrogen oxides directly into the stratosphere, which also contributes to ozone destruction.

About Environmental Chemistry
Atmospheric pollution includes smog, acid rain, greenhouse gases, ozone depletion and the effects of carbon monoxide, sulfur oxides, nitrogen oxides and particulate matter. Water pollution covers sewage, industrial waste, eutrophication and treatment stages, while green chemistry focuses on reducing hazardous substances, waste and energy use through safer, more efficient processes.
