Accumulation and translocation of lead and cadmium in Lyophyllum decastes.
Lyophyllum decastes (L. decastes) is a very precious edible mushroom. With simple structure, mushrooms have been proved to have the phenomenon of accumulating heavy metals. To investigate the accumulation and transfer of L. decastes to heavy metals and the effects of heavy metals on agronomic traits and yield, we used lead (Pb) and cadmium (Cd) inhibitory test for L. decastes. The results indicated that the addition of Pb and Cd affected the growth of aerial mycelium, and thus decreased the growth rate of mycelia. At a Cd concentration of 50 mg L-1, the mycelium reached its maximum tolerance concentration, but the maximum tolerance concentration of the mycelium had exceeded 1500 mg L-1. The addition of Pb and Cd led to the deterioration of agronomic traits and the decrease of yield. At the same concentration (20 mg kg-1), the negative effects of Cd on agronomic traits and yield were greater than that of Pb. The BAF values of the pileus and stipes under Pb treatments were < 1, which indicated that L. decastes was the bioexcluders of the elements Pb. The TF values were all greater than 1 under Cd treatments, indicated that the transfer ability of Cd was strong. This advancement has enhanced our knowledge of how heavy metals accumulate and distribute in mushrooms. The transfer ability of Cd was strong.
期刊介绍：
Environmental Geochemistry and Health publishes original research papers and review papers across the broad field of environmental geochemistry. Environmental geochemistry and health establishes and explains links between the natural or disturbed chemical composition of the earth’s surface and the health of plants, animals and people.
Beneficial elements regulate or promote enzymatic and hormonal activity whereas other elements may be toxic. Bedrock geochemistry controls the composition of soil and hence that of water and vegetation. Environmental issues, such as pollution, arising from the extraction and use of mineral resources, are discussed. The effects of contaminants introduced into the earth’s geochemical systems are examined. Geochemical surveys of soil, water and plants show how major and trace elements are distributed geographically. Associated epidemiological studies reveal the possibility of causal links between the natural or disturbed geochemical environment and disease. Experimental research illuminates the nature or consequences of natural or disturbed geochemical processes.
The journal particularly welcomes novel research linking environmental geochemistry and health issues on such topics as: heavy metals (including mercury), persistent organic pollutants (POPs), and mixed chemicals emitted through human activities, such as uncontrolled recycling of electronic-waste; waste recycling; surface-atmospheric interaction processes (natural and anthropogenic emissions, vertical transport, deposition, and physical-chemical interaction) of gases and aerosols; phytoremediation/restoration of contaminated sites; food contamination and safety; environmental effects of medicines; effects and toxicity of mixed pollutants; speciation of heavy metals/metalloids; effects of mining; disturbed geochemistry from human behavior, natural or man-made hazards; particle and nanoparticle toxicology; risk and the vulnerability of populations, etc.
