摘要

To discuss the maternal-fetal transfer of persistent organic pollutants (POPs) in viviparous fish, the whole-body burdens of POPs were determined in gravid surfperches from Otsuchi Bay, Japan, and in their fetuses. The concentrations were 2.75-15.5 times higher in the maternal tissue. To compare the characteristics of the maternal-fetal transfer between species with different gestation systems, reports on the striped dolphin and long-finned pilot whales were studied. The transfer rates of POPs in surfperches were 0.6-6.0%, while in marine mammals they were 3.0-9.4%. The difference in transfer rates may derive from the difference in their reproductive systems. On the other hand, as in marine mammals, selective transfer of POPs was seen in surfperches. The transfer rates were higher in less hydrophobic compounds such as dieldrin, and lower in more hydrophobic compounds such as DDTs. A new transfer factor is also discussed which instantly indicates the difference in the concentrations between mother and fetus. (c) 2005 Elsevier Ltd. All rights reserved.
