Bioaccumulation of Nonylphenol Isomer in Metaphir eguillelmi and Its Influence on Growth
摘要
Abstract
A laboratory experiment was conducted using 14 C-tracer to investigate bioaccumulation of 14 C—p353—NP in Metaphire guillelmi and its influence on growth of the worm. Results show that after 96 days of exposure, the concentration of 14C—p353—NP in Metaphire guillelmi was measured to be 4.45~6.79 mg·g-1(wet weight)with BSAF being in the range of 0.95-1.89. In the 14C—p353—NP-treated groups, earthworms exposed to 14C—p353—NP, 128、160 and 200 mg·kg-1 in concentration were inhibited significantly in growth ( P<0. 05 ) . Bioaccumulation of14 C—p353—NP in Metaphire guillelmi and its inhibitory effect on growth was closely related to concentration of 14 C—p353—NP in the soil and duration of the exposure and their interaction ( P<0.001) . It was found that 14 C—p353—NP might keep on accumula-ting in Metaphire guillelmi, and inhibiting its growth till it reached up to its sublethal concentration (≤200 mg·kg-1). The findings of the research may serve as basic data for assessment of bio-toxicity and ecological risk of p353—NP in soil.关键词
