This is an extract from dissertation on Biomagnification:
Every year millions of people get cancer and it’s a major problem in the United States that many people do not like to think about because of how it could impact their lives! Some of these cancers can be linked to a process known as biomagnification, or biological magnification. Biomagnification is a result of bioaccumulation and they are related, yet very different (McGrath 78). These two terms, biomagnification and bioaccumulation, are processes that are causing more damage to the environment than most people think. There are many pollutants that affect these processes and they are commonly dumped into waterways or released into the air. Some of these common pollutants are DDT, PCBs, Polynuclear Aromatic Hydrocarbons (PAHs), lead, and mercury. These pollutants are catastrophic for Mother Nature, as well as humans. Biomagnification is a serious dilemma for life on Earth because it only takes a few pollutants to eventually concentrate to very high levels of toxicity in animals, including humans, after they have consumed lower-level organisms that have been previously contaminated with harmful pollutants.
