Levels of metals were assessed in topsoil, dust, leaves, grass, lichen and bark from the Kruger National Park using electrothermal atomic absorption techniques. It was found that dust, lichen and bark reflected the levels of air pollution better than grasses or leaves of trees. It is suggested that the difference in levels of accumulated metals in the bark or lichens could be used as an indicator of air pollution in remote areas.
利用电热原子吸收技术对克鲁格国家公园表土、灰尘、树叶、草、地衣和树皮中的金属含量进行了评估。研究发现，灰尘、地衣和树皮比草或树叶更能反映空气污染水平。研究表明，树皮或地衣中累积金属含量的差异可作为偏远地区空气污染的一个指标。
