In total, 41 compounds were analyzed which includes 16 PAHs, 16 deuterated PAHs used as internal standards (IS) and 9 PCBs. Up to three MRM transitions per compound were employed wherever possible ...

Recent tests of the sediment, located in a section of lake bottom known as Area 1, found alarmingly high concentrations of PCBs and PAHs -- both highly toxic pollutants and 100 percent fatal to ...

An EFSA model calculation (EFSA 2016a) shows that the daily intake of PCBs and PAHs through the consumption of contaminated microplastic particles in mussels can only increase by 0.006 % for PCBs ...

The compounds, which include notorious chemicals such as polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs), settle in river sediments and make fish and shellfish unsafe ...

As Wainstein’s study suggests, perhaps not. The otters she analyzed in the lower Duwamish have some of the highest concentrations of PCBs and PAHs ever recorded in wild river otters.

The tests found elevated levels of PCBs and PAHs at two locations: one in sediment closest to the water intake site, and the second at the furthest location from the water intake pipe, Princic said.

As Wainstein’s study suggests, perhaps not. The otters she analyzed in the lower Duwamish have some of the highest concentrations of PCBs and PAHs ever recorded in wild river otters.

"Plastic lasts a very long time in the environment," Liu said. "Our preliminary data shows higher concentrations of PCBs and PAHs in nurdles. It's concerning." 3. Citizen volunteers are helping ...

PCBs and PAHs are classified as carcinogens by the National Institutes of Health. The state has not reported any contamination on the Little People's College day care property at 52 Donald St.
