摘要：The present study was conducted to find out effect of PFOS on survival,activity,growth and organ structure of the melania snail,Semisulcospira gottschei. Experimental groups were composed of one control condition and four PFOS exposure condition (0.1,0.5,1.0 and 5.0 mg/L). After 16 week exposure,survival rate and activity were not significantly influenced at the two lower exposure groups,0.1 and 0.5 mg/L,but they were significantly reduced in 1.0 and 5.0 mg/L groups. Total weight and meat weight rate (MWR) were reduced in PFOS exposure group in comparison to control group. Also,histological degenerations such as acidification of mucous,necrosis and split of muscular fiber bundle,atrophy of anterior pedal gland were recognized in the foot. Hepatopancreas showed the atrophy and degeneration of the digestive cell,vacuolation of digestive gland and closure of lumen in digestive gland.
