Atmospheric pollution deposits, largely consisting of soot, were removed from sycamore leaves growing downwind of a coking plant, and added to soil. Increases in plant available S-ions (S₂O₃²⁻; S₄O₆²⁻ and SO₄²⁻) and N (NH₄⁺ and NO₃⁻) occurred due to the action of soil micro-organisms on the deposits. Although the detrimental effects of air pollution on plant growth have been previously emphasised, supply of nutrients resulting from the microbial transformation of particulate pollutants may prove important to the growth of pollution-resistant plant communities.
