Acid Rain

Causes

• Burning of fossil fuels
• smelting of metals in old industrial plants
• exhast fumes

Acid deposition consists of dry deposits of pollutants - sulphur Dioxide and Nitrogen Oxide
They mix with precipitation to produce wet deposits of sulphuric acids, nitric acid and compounds of ammonia (acid rain)

Effects

• Damage to conifers - yellowing of needles and strange branching patterns
• Acidification of lakes and streams - killing aquatic life reducing biodiversity
• leaching of toxic metals (aluminium) from soil into rivers &lakes also killing fish - also reduces nutrient content of soils so plants can't grow
• Decay of building…
