Mudsnails and sediments from an electronic waste recycling region in South China were chosen to study the polybrominated diphenyl ethers (PBDEs) bioavailability of mudsnail in different ambient levels. Significant (p < 0.05) correlations of biota-sediment accumulation factor (BSAF) versus the reciprocal of PBDE concentration in sediment (1/Sed) occurred in all quantitative PBDE congeners except BDE-209, showed that the BSAFs of PBDEs in mudsnails were increased with reciprocal increasing ambient levels. The BDE-183 correlation of mudsnail versus sediment (r = 0.580) was much lower than the correlation of BDE-209 versus BDE-183 in mudsnails (r = 0.812), indicated the main source of BDE-183 in mudsnails was from the debromination of higher brominated PBDEs.
选取中国南方某电子垃圾回收区域的泥螺和沉积物，研究不同环境水平下泥螺对多溴二苯醚（PBDEs）的生物可利用性。除BDE - 209外，所有定量PBDE同系物的生物群 - 沉积物积累因子（BSAF）与沉积物中PBDE浓度的倒数（1/Sed）均存在显著（p < 0.05）相关性，表明泥螺中PBDEs的BSAFs随环境水平倒数的增加而增加。泥螺与沉积物中BDE - 183的相关性（r = 0.580）远低于泥螺中BDE - 209与BDE - 183的相关性（r = 0.812），这表明泥螺中BDE - 183的主要来源是高溴代PBDEs的脱溴作用。
