%X Phosphine in Lake Taihu sediment cores were monitored by a GC/NPD method,coupled with cryo-trapping enrichment technology.Results show that phosphine is universally detected in sediment cores,its concentration ranges from 0.15ng/kg to 36.1 ng/kg.The concentration of phosphine varies with different sampling sites and depths.Representative microorganisms(aerobic bacteria,anaerobic bacteria,actinomycete,inorganic phosphobacteria and organic phosphobacteria) in surface sediments were also identified.The amount and distribution of microorganisms positively correlate with different contamination and salty levels of the samples.A markedly positive linear correlation between the concentration of phosphine and the numbers of inorganic phosphobacteria could be observed(R2=(0.817,) n=6).There is not a correlation between phosphine level and organic phosphobacteria quantities.
