From the Mariana trench, noted elevated levels of toxic pollution
Source:
The Results of a new study published in the journal Nature Ecology and Evolution, point to the "extremely elevated levels" of toxic contamination on the ocean floor of the Mariana trench, often known as one of the most remote places on the planet. The most dangerous thing in this case describes the so-called "persistent organic pollutants" (POPs), which since the 1930s and the 1970s, was used in the production of lubricants for engines and refractory materials. Gravity and many years of ocean waste disposal of these dangerous chemicals down to a depth of 11 kilometers.
The Harm from POPs immediately obvious for several reasons. One of them is that these chemicals are dangerous not only for humans but also for fish and mammals. Exposure to these substances over time can cause serious illnesses, birth defects and ultimately death. But it's not even the worst. The fact that the information contained in these substances toxins do not break down naturally in nature. Moreover, POPs can accumulate in fatty tissues of organisms, and this, in turn, suggests that they are able to advance further in the food chain and impress more and more living organisms.
"We continue to consider the deep ocean as one of the most remote from human influence, but our recent studies show a bleak picture: soon we will have to reconsider this opinion," — says Alan Jamieson, lead author of the study persistent organic pollutants discovered in the Mariana trench.
"the discovery of such high levels of these contaminants only once again confirms the opinion about the horrible negative impact on the planet in the long term can carry a human activity".
It Should be noted that this is not the first case of detection of negative consequences of human impact on the world's deepest ocean trench. A year earlier in the journal Nature has published an article which provided evidence for the presence of other dangerous pollutants near the Mariana trench. This news, in turn, came just a month after publication of the results of research scientists of the University of Oxford, which to find still untouched by human civilization on our planet.
