Both PFOS and PFOA persist indefinitely in the environment, bioaccumulate in humans and animals over long periods of time, and biomagnify as they are consumed up the food chain.
Other associated toxins which can transform into BMAA were present, but did not biomagnify up the food chain i.e.
(2014) warned of the fact that small concentrations of heavy metals in the environment are already a serious risk, especially for species chain moles (such as man) since heavy metals have the capability to bio-accumulate and biomagnify in the ecological pyramid.
These chemicals accumulate in lipophilic tissues, biomagnify through the food chain and have been found globally, even in regions where they have never been used [5].
MeHg is the only form of mercury to biomagnify in food webs, reaching concentrations in predatory species such as shark, tuna, and swordfish that are at least a million times higher than seawater (Lavoie et al.
Importantly, Se can biomagnify in ecosystems [63] and it has been suggested that 4 ppm of selenium in plants is the tolerance limit for animals and levels above 5 ppm could be a concern [64].
Inorganic mercury in aquatic environment is transformed by microorganism into methyl mercury which is lipophilic and biomagnify in the food chain.
The substances present in e-waste have the capacity to bioaccumulate and biomagnify along the food chain.
When carnivorous fish consume toxic herbivorous fish, the toxins can accumulate in them as well, allowing the toxins to biomagnify up the coral reef food chain.
The main reason behind this rapid lose is that Cr(VI) not only cumulated in tissues during aquatic organisms growth (bioaccumulation) but also biomagnify up the food chain and thus fish faced both metallic stress as well as starvation.
over time, biomagnify, causing widespread, long-term, and severe damage
This variation may be attributed on one hand, to their habitats and on the other hand to their inherent abilities to biomagnify the heavy metals.
