Geographic variation in the prevalence of respiratory disease between communities has been used to incriminate air pollution at low concentrations in the production of disease. Though demographic factors and the design and conduct of survey research affect the validity of these observations, there are other complex factors which are often neglected. From several community studies planned or conducted by the authors, illustrations will be given of the effect of the following six frequently neglected factors: the reliability of the air pollution monitoring network; the validity of the air pollution monitoring network; the competing effect of differential migration of population; the competing effect of occupational pollution of members of the population; the competing effect of socioeconomic factors; and the competing effect of personal air pollution—tobacco smoking. 相似文献

The goal of this study was to evaluate cadmium and lead accumulation ability of in vitro cultures biomass containing selected edible mushroom species derived from the environment (Laetiporus sulphureus, Imleria badia) and those of commercial origin (Agaricus bisporus). Atomic absorption spectrometry was used to evaluate the content of Cd(II) and Pb(II) on the medium supplemented with Cd(II) or Pb(II), each of them at the same concentration of 5·10?5 M. The highest concentration of Cd(II) ions was determined in the biomass from L. sulphureus in vitro cultures, while the highest concentration of Pb(II) ions was found in the biomass from A. bisporus in vitro cultures. The greatest Cd(II) and Pb(II) accumulation ability in mycelium per dry weight was shown for L. sulphureus. Among the test species, biomass of A. bisporus showed the lowest ability for the bioaccumulation of Cd(II); however, comparable ability for the remediation of Pb(II) was provided by the biomasses from A. bisporus and I. badia in vitro cultures. The results confirm the possibility of using these mushroom species for remediation and indicate the relationship between bioaccumulation of heavy metals and the test species. 相似文献
