Abstract
Premature pupping in California sea lions has been noted on the breeding islands since 1968. Organochlorine pesticides and polychlorinated biphenyl residues were two to eight times higher in tissues of premature parturient females and pups than in similar tissues of full-term parturient females and pups collected on San Miguel Island in 1970.
摘要
自1968年以来，在繁殖岛屿上就已注意到加利福尼亚海狮早产的情况。1970年在圣米格尔岛采集的早产母兽和幼崽组织中的有机氯农药和多氯联苯残留量，比足月产母兽和幼崽的类似组织中的残留量高出两到八倍。
