Mercury and heavy metal profiles of maternal and umbilical cord RBCs in Japanese population.

abstract：:Ecological risk assessment is defined both in theory and in practice. To do it properly, we need to know what targets we are protecting, but these targets are not always obvious and clearly defined. The pragmatic approach, used most generally in the context of environmental protection legislation, is the risk quotient...
