六六六在水环境中转移、积累和归趋研究——2.斜生栅藻和裸腹溞对六六六的积累
TRANSPORT AND FATE OF BHC IN AQUATIC ENVIRONMENT 2. BHC ACCUMULATION IN SCENEDESMUS OBLIQUUS AND MOINA
-
摘要: 斜生栅藻和裸腹搔对六六六的积累系数分别为213和32(以湿重计);它们的死体也同样能积累六六六。在氧化塘或其他富营养化的水体中,浮游生物在六六六由水向底泥转移中起着载体的重要作用。Abstract: Studies show that aeeunmlation factor of Scenedesmus oiliquus and Moina was 213 and 32 (wet weight), respectively. Dead bodies of organisms also accumulated BHC. The concentration of BHC in organisms was dependent on both the concentration of BHC in water and the biomass of algae and zooplankton. These organisms play an important role in the transport of BHC from water to bottom sediments.
