| Those effects are exacerbated in piscivorous species, because of the tendency of PCBs to biomagnify at upper trophic levels. |
| Any form of Hg can be converted to methylmercury by natural means and then bioaccumulate and biomagnify as it progresses through aquatic food webs. |
| But even after grappling with the concept of potentially harmful natural products, I was still captivated by the idea that some natural products could biomagnify. |
| Each of these compounds are important contaminants in biological systems as they readily bioaccumulate and biomagnify in the food chain. |
| Remote camera observations revealed that the nestlings died shortly after consuming sand lance, a fish species known to biomagnify saxitoxin. |
| Therefore, copper does not bioaccumulate or biomagnify in aquatic or terrestrial food chains. |
