大气氟污染源附近食桑昆虫中氟的积累和分布

对大气F污染源附近野桑蚕，桑赤蠖和桑蚕体内的氟化物含量和器官分布进行了研究，结果表明，污染源附近食桑昆虫体有较高的氟化物含量，且食桑昆虫体的氟化物含量随着离污染源的距离增大而降低，野桑蚕，桑赤蠖和桑蚕的氟化物含量与桑叶的氟化物含量有极显著的线性正相关性，食桑昆虫不同器官间的氟化物积累量也存在较大差异，其消化管是食桑昆虫的主要氟化物积累器官。

Fluoride accumulation and distribution in mulberry insects near fluoride pollution sources.

Fluoride accumulation and the relative fluoride loading of different body parts in wild mulberry silkworm (Bombyx mandarina M.), mulberry geometrid (Pathonandria atrineata B.), and mulberry silkworm (Bombyx mori L.) near fluoride pollution sources were studied. Comparison of the fluoride content of insect bodies and mulberry leaves showed that insects collected from polluted sites had increased fluoride accumulation. The digestive tract of the insect had much higher fluoride content than the other parts of the body and was considered to be the important organ of fluoride accumulation. There were also wide differences in fluoride accumulation between different insect species within the same polluted site. The highly significantly correlation between fluoride contents of wild mulberry silkworm, mulberry geometrid, and mulberry silkworm with that of the mulberry leaves on which they were collected was found.
