Abstract/Contents:"Mosses have been used as biomonitors of atmospheric pollution for some years, but few studies have been carried out on the effect of NOₓ emissions from traffic dnsities were collected from urban and rural sites in the walls or roofs next to roads exposed to different traffic densities were collected from urban and rural sites in the UK. The shoots were sampled for total N, their stable isotope ¹⁵N/¹⁴N content (δ¹⁵N) and heavy metal content (Pb, Zn). There was a lack of correlation between tissue total N and traffic exposure, but a very good correlation between traffic exposure and tissure δ¹⁵N. Plants collected near motorways or busy urban roads had δ¹⁵N values ranging between +6 and -1%ₒ, while in rural areas with hardly any traffic these ranged from -2 to -12%ₒ. In a separate survey of mosses, the average δ¹⁵N of shoots from busy roadsides in London was +3.66%ₒ, whereas from samples collected from farm buildings near poultry or cattle pens it was -7.8%ₒ. This indicates that the two main atmospheric N sources, NOₓ and NHₓ, have different δ¹⁵N signatures, the former tending to be positive and the latter negative. Tissue concentrations of both Pb and Zn show a strong positive correlation with traffic exposure, with Zn in particular being greater than Pb. The results are discussed with regard to the use of moss tissue Zn as a means for monitoring or mapping polution from vehicles, and of δ¹⁵N as an aid to distinguish between urban (NOₓ) and rural (NHₓ) forms of N pollution."
