“…Bryophytes and lichens are especially effi cient in absorbing elements directly across their surfaces because they have neither epidermis or cuticle layer, nor roots [156]. Not surprisingly, therefore mosses and lichens are widely used as biomonitors of metals (see also Section 5.2).…”

“…With the exception of the aquatic and semiaquatic mosses, nearly all mosses rely on the atmosphere for most of their nutrients (Tyler, 1990 ;Steinnes et al, 1994 ;Soares & Pearson, 1997), *Author for correspondence (fax j44 20 7380 7096 ; e-mail john.pearson!ucl.ac.uk).…”

Traffic exposure increases natural ¹⁵N and heavy metal concentrations in mosses

Mosses have been used as biomonitors of atmospheric pollution for some years, but few studies have been carried out on the effect of NO x emissions from traffic on moss tissue N. Eight species of moss (102 samples) growing on 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 "&N\"%N content (δ"&N) 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 tissue δ"&N. Plants collected near motorways or busy urban roads had δ"&N values ranging between j6 and k1=, while in rural areas with hardly any traffic these ranged from k2 to k12=. In a separate survey of mosses, the average δ"&N of shoots from busy roadsides in London was j3.66=, whereas from samples collected from farm buildings near poultry or cattle pens it was k7.8=. This indicates that the two main atmospheric N sources, NO x and NH x , have different δ"&N 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 pollution from vehicles, and of δ"&N as an aid to distinguish between urban (NO x ) and rural (NH x ) forms of N pollution.

“…Bryophytes in particular have been employed over the past decades as biomonitors for the assessment of airborne pollutant deposition, including heavy metals (Harmens et al, 2007;Rühling and Tyler, 1969;Tyler, 1990), radionuclides (Sawidis et al, 2009;Sumerling, 1985), persistent organic pollutants (Carlberg et al, 1983;Migaszewski et al, 2009) and nitrogen (Poikolainen et al, 2009;Solga et al, 2006;5 Wilson et al, 2008). Characteristics of mosses make them excellent subjects for biomonitoring.…”
