STUDIES ON THE ACCUMULATION OF HEAVY METALS AND THEIR EFFECT ON THE GROWTH AND METABOLISM IN EDIBLE FUNGI
重金属在食用菌中的富集及对其生长代谢的影响

The absorption and accumulation of heavy metals in edible fungi and the effects of heavy metals on the growth and the metabolism of edible fungi were investiga- ted.The results showed that Lentinus edodes,Pleurotus membrancens,Flammulina velueipes and Auricularia auricula accumulate Hg,As,Ni,Cd,Cu,Zn,Pb to various degrees.Among the heavy metals tested,Hg was highly accmulated by edible fungi.But the accumulation of Pb was weak.The examination of edible fungi from different producing areas in Fujian pro- vince indicated that the content of heavy metals in the fruiting bodies of all edible fungi were below the hygienical standards. Heavy metals mentioned above were harmful to the growth and yield of edible fungi,es- pecially Hg and As.They could activate Vitamin C oxidase and inhibit cellulase.
