摘要: Nieboer et al. (1978) and Richardson (1981) have given a comprehensive summary of the range element levels found in lichens. The data they present show tremendous concentration ranges correlating with different or contrasting environments particular 10–100 fold increases metal concentrations near ore smelters. origin elements lichen thalli is twofold: from particulate atmospheric “fallout” ionic solutions. latter may be delivered to thallus either directly as rainfall indirectly surface runoff.
