Acid precipitation is now regarded as a serious problem in some European and Asian countries. Its major cause or source is __________________.

  1. discharge of effluents into neutral or slightly alkaline land where the acidic components precipitate

  2. emissions of sulphur oxides and nitrogen oxides from thermal power plants and burning the fossil fuels; these oxides dissolve in atmospheric water vapour and fall back on earth as acid rain

  3. natural carbondioxide released during respiraion of living organisms dissolves in water, forming carbonic acid which is chief contributor to acidity in rain water

  4. chloroflurocarbons readily react with various chemicals near the earth's surface, producing acidic intermediates which cause acid precipitation
