Pollution reached such an alarming extent that even places that no one could have thought of ended up affected by it. Although one might regard them as inaccessible, even marine life in deep sea trenches are victims of pollution.
Researchers look at life forms from these trenches and found in them toxic chemicals that have been banned worldwide since 1970s. The largest percentages discovered were of polychlorinated biphenyls (PCBs), but many other pollutants were discovered even 10 kilometers below sea levels.
The deep sea trenches whose sea life was found to contain alarming amounts of toxic pollutants are the Mariana Trench, located 1,300 kilometers away from Japan, or the Kermadec Trench, 1,500 kilometers from New Zealand.
Dr. Alan Jamieson is one of the researchers that took place in the study of pollutants. He stated that the fact they found pollutants even at such depths indicated what long-term effects pollution can have on Earth and that they could reach even remote areas. We have to be careful since toxic pollutants can resist entire decades.
The researchers informed that the pollutant levels found in deep sea trenches was comparable to the levels in the most industrially polluted area in Japan. Suruga Bay is regarded as one of the most polluted areas in the Pacific Ocean.
They will continue the research on how this waste is affect marine life in deep sea trenches and how it ended up in such remote areas in the first place. So far, they identified as causes accidents, leaks from landfills, or even deliberate garbage dumping. The pollutants could have either drifted down into the sea or came from dead animals who consumed the toxic waste.
The pollutants are, of course, not biodegradable, so they accumulate and cause environmental hazards. Not even in the stomachs of dead animals do they degrade. Among the animals that consume pollutants are many species of crustaceans from the Mariana Trench. This is one of the most polluted deep sea trenches, with 50 times the average quantities of PCBs.
Pollution is a problem that greatly expanded and reached places no one would have thought of as accessible. People should be more aware of the effects of pollution and should be careful with what they throw away, where they do it, and think more of the environment.
