几种重金属对皱纹盘鲍血细活性氧产生的影响

体外条件下利用化学发光法定量地研究了不同种类和不同浓度的重金属:Cr、Cd、Hg、Pb、C和Zn对皱纹盘鲍血细胞吞噬时活性氧产生的影响。结果表明,不同种类和不同浓度的重金属浸泡急性处理皱纹盘鲍血细胞都不同程度地抑制了血细胞吞噬时的化学发光,表明重金属能够抑制皱纹盘鲍血细胞吞噬活动中的活性氧(ROS)的产生,而且这种抑制作用随着重金属浓度的增加而加强。不同的重金属抑制强度不同,从强到弱以次为Hg>Cd>Cu>Pb>Cr>Zn。研究表明六种重金属中,Hg对皱纹盘鲍血细胞的免疫毒性最大。

Effect of leachate recycling and inoculation on the biochemical characteristics of municipal refuse in landfill bioreactors

Activity development of key groups of enzymes involved in municipal refuse decomposition was measured in laboratory landfill bioreactors with and without leachate recycling and inoculation for about 210 days.The results showed that the enzymes(amylase,protease,cellulase,lipase and pectinase)were present in fresh refuse but at low values and positively affected by leachate recycling and refuse inoculation.The total average of cellulase activity in digesters D3 operated with leachate recycling but no inoculation,D4 and D5 operated with leachate recyling and inoculation was much higher than that in digesters D1 and D2 without leachate recycling and inoculation by 88%-127%,117%-162%and 64%-98%.The total average of protease activity was higher in digester D4 than that in digesters D1,D2,D3and D5 by 63%,39%,24%and 24%,respectively,and the positive effect of leachate recycling and inoculation on protease activity of landfilled refuse mainly was at the first two months.The total average of amylase activity was higher in digesters D3,D4 and D5 than that in digesters D1 and D2 by 83%-132%,96%-148%and 81%-129%.During the early phase of incubation,the stimulatory effect of inoculation on lipase activity was measured,but refuse moisture was the main factor affecting lipase activity of landfilled refuse.The inoculation,initial and continuous inoculation of microorganisms existing in leachate,was the mainly stimulatory factor affecting pectinase activity of landfilled refuse.
