Because of their large fat deposits and position at the top of the marine food chain, Shaw points out, "all marine mammals are bioaccumulating large quantities of environmental pollutants." Indeed, it's because of these properties, Osterhaus says, that "if any kind of adverse effects were to be expected, then [marine mammals] are the first you'd expect to see them in."
A particular focus is put on fish consumption, because fish are a major route of exposure to bioaccumulating contaminants (Turyk et al.
An important exception to this observation is methylmercury, which also possesses known bioaccumulating and toxic properties, and is the primary target of many published fish consumption guidelines (FDA 2004; Ontario Ministry of the Environment 2011).
In other parks, phthalates typically used in the production of paper cups and Styrofoam containers were bioaccumulating in fish.
If natural products are bioaccumulating in the same manner as industrial compounds, Teuten noted, then some marine animals have been exposed to these natural chemicals for many years.
The fact that dust can be a source of exposure to flame retardants was first revealed by investigations into why compounds associated with polybrominated diphenyl ether (PBDE) flame retardants were bioaccumulating in people's bodies.
PentaBDE poses a risk to the environment, is bioaccumulating and has been found in breast milk in increasing concentrations.
The long-lived, late-maturing, and benthic lifestyle of sturgeon may make them particularly susceptible to the actions of persistent bioaccumulating pollutants (DeVore et al.
1998; Van Der Kraak 1998), and many of these bioaccumulating toxicants have been detected in sediments and fish from the Columbia River [Foster et al.
"This shows that pollution levels in the ocean are at such a bad level that even filter feeders are bioaccumulating some kinds of contaminants," says Frank Cipriano, director of the Conservation Genetics Laboratory at San Francisco State University.
Discussions and presentations emphasized the involvement of bioaccumulating, primary organochlorine contaminants such as PCBs, DDTs, and other pesticides, as well as exposure to metals and metal-containing organics such as methylmercury and organotins.
Long-abandoned North American gold mines and contemporary small-scale artisanal mines in the Amazon are an ongoing source of mercury, which is bioaccumulating in food fish.
