Air pollution
♦️ Acid rain
👉 Acid rain results when gaseous emission SOx & NOx interact with water vapour and sunlight and are chemically converted to strong acidic compounds (H2SO4 & HNO3) along with other organic and inorganic chemicals.
👉 If pH of rain less than 5.6 is called acid rain
♦️ Global warming
🔸 The major green house gases
👉 Carbon dioxide :- 57%
👉 Methane :- 12%
👉 Nitrous oxide :- 6%
👉 Chlorofloro carbon (CFC) :- 25%
♦️ Ozone layer depletion
👉 Primary reason of ozone layer depletion is CFC
