Abstract
SURVEYS of heavy metal pollution using bryophytes have produced valuable information about lead levels in the environment. Hypnum cupressiforme Hedw., Hylocomium splendens (Hedw.) B. and S., Pleurozium schreberi (Brid.) Mitt., and Sphagnum magellanicum Brid. have been used to demonstrate regional gradients of lead and other non-ferrous metals in Sweden1–4, and high levels of lead and other metals have been found in Hypnum cupressiforme downwind from the Swansea urban industrial complex5. Centres of large urban areas, where pollution-sensitive pleurocarpous mosses are absent but where high levels of lead might be expected, have not been studied.
