Remote camera observations revealed that the nestlings died shortly after consuming sand lance (Ammodytes hexapterus), a fish species known to biomagnify
 have shown that mayflies Centroptilum triangulifer (Ephemeroptera) feeding on periphyton organisms are able to biomagnify
Large number of experiments proved that PBDEs including BDE-209 persist in the environment for long time (de Wit 2002), and bioaccumulate and biomagnify
as they move through the food chain (Law et al.
Numerous of these chemical contaminants are persistent polyhalogenated aromatic hydrocarbons known to bioaccumulate and biomagnify
as they move through the aquatic food web, affecting species associated with aquatic systems, including humans (GIESY et al., 1994; PEREIRA, 2004).
The succeeding lower bio concentration factor, in higher trophic animals, indicates that thorium will not biomagnify
in the aquatic environment.
Although it can persist in sediments and accumulate in sediment-dwelling organisms, it does not biomagnify
through the food chain.
The only known metals to biomagnify
in aquatic organism are methylmercury and possibly selenium (PARAMETRIX, 1995 apud ICMM, 2007).
Therefore, copper does not bioaccumulate or biomagnify
in aquatic or terrestrial food chains." He is quick to point out, though, that point source emissions should be avoided and thus containment and handling of waste from vessel dry-dockings or pleasure craft maintenance is important.
These compounds have great affinity for fatty molecules what makes it easier to be accumulated in the fat tissue of organisms; as a consequence they can be biomagnify
along the food chain, where its degradation products are more toxic or permanent than the original compound (Henao et al.
Many contaminants biomagnify
up food webs to reach significant concentrations in top predator species.
Any form of Hg can be converted to methylmercury by natural means and then bioaccumulate and biomagnify
as it progresses through aquatic food webs.
