The dead cetaceans, predators at the very top of the maritime food chain, would have picked up the toxins from shellfish and smaller animals which accumulate pollutants, Lenghaus said.

Coastal cetaceans not only pick up chlorinated hydrocarbons, but also accumulate other industrial pollutants such as heavy metals.

M. importuna and other edible mushrooms may accumulate pollutants when growing in contaminated areas.

Mushrooms growing in polluted locations can accumulate pollutants such as heavy metals.

Because they are so efficient at filtering water, they tend to accumulate pollutants and toxins.

Like many other lakes, Memphremagog is faced with accumulating phosphorus, sediments, and other pollutants from a variety of sources.

Unfortunately, the big marine species that people like to catch, the big stripers and larger bluefish, are just the fish people shouldn't be eating because they've been accumulating pollutants.

Stormwater Stormwater runoff is generated when rain and snowmelt do not soak into the ground but flow over land or impervious surfaces, accumulating pollutants that could adversely affect water quality.

Marine top predators like porpoises and seals accumulate pollutants such as heavy metals, PCBs and pesticides in their fat tissue.

As the runoff flows over the land or impervious surfaces, including paved streets, parking lots, and building rooftops, it accumulates debris, chemicals, sediment and other pollutants.
