Dear Margaret,
 
Bioaccumulation is a well defined term - which can also be understood as raising the concentration in the body of the substance in question.

As an example mercury is often bioaccumulated - in soil bacteria, plants, animals and humans, maybe due to extensive burning of coal. Bioaccumulation is the result of taking-up more then releasing. Low levels of bioaccumulation may have eventually no visible effects, repeated exposure with higher levels will surely lead to serious adverse health effects.
 
Despite this, repeated exposure to hazardous chemicals with no or low bioaccumulation potential will also lead to long term effects by damaging the organism each time when exposed. In addition genetic defects and alike will automatically lead to long term effects.
