For decades, many chemical companies, as well as US military personnel, have treated the waters on the shores of the southern California as a toxic place of dumping, creating 14 places where chemicals were deposited as DDT.
-
Some of those barrels of toxins around them created Hale -like circles, which indicate that hazardous material has leaked from the barrels.
-
In a new study, which analyzes these halas, they found that they mimicked the most extreme environment on Earth-to-beyond hydrothermal openings and caused alkaline waste interacting with magnesium and a concrete-like crust called Brucite.
Since 1930 Until 1970 Several government agencies have confirmed the dumplings of hazardous substances, including chemicals such as DDT and other caustic waste, 14 places on the shores of California. By Los Angeles TimesAt the time, the idea was that “dilution was a solution of pollution”, basically the use of the world’s oceans, to reduce harmful chemicals to a million parts of harmless parts (PPM).
The idea was not implemented by plan – an unpleasant perspective with about half a a million Barrels are still underwater today.
Armed with remotely controlled vehicle (ROV) Subastian, located on board the Mesearch Land Falkor, scientists at the UC San Diego Scripps Institute of Oceanography looked more closely at these barrels with ocean floor and found something suffering. Of many of them emanates the ghostly halo, offering something went out into the ocean environment. In a study published in the magazine Connection of the National Academy of Sciences (PNA)The authors describe in detail the results of humanity widely despite the ocean ecosystems.
Meanwhile, researchers hoped to find DDT concentration – pesticide, which is the main chemical antagonist of Rachel Carson’s book The silent spring, and whose use is now illegal in the US – they instead learned that halas were made of alkaline caustic waste that forms an extreme environment. The team says Halos mimics areas such as hydrothermal openings.
“DDT was not the only thing that was thrown in this part of the ocean, and we only have a very broken idea of what was thrown there,” Johanna Gutleben, co-author of the investigation, said in a press release. “We only find what we are looking for, and so far we have been mostly looking for DDT. No one has thought about alkaline waste before and may have to start looking for other things.”
Hala formed a thick, concrete -like crust that ROV was difficult to assemble using Coring devices. Instead, Subastian relied on a robotic hand to tear the pieces for further analysis. Studies show that when alkaline waste leaked from the structures, its reactions with magnesium in sea water created a brucite, a mineral form of magnesium hydroxide. Where this high pH material meets with sea water at the edges of the sea, it forms calcium carbonate – chalk, the outer edge of the halo.
“It is shocked that after 50 plus you are still seeing these consequences,” said Paul Jensen, another co-author of the investigation in a press release. “We cannot quantify the environmental impact, not knowing how many of these structures with white hala are there, but it clearly has a local effect on microbes.”
Unfortunately, removing these ecological disasters is not easy, as the ocean floor is likely to be created by sediment, which further spread contamination throughout the water column. The best hope is to investigate DDT pretended sediment and see what microbes could break down the chemical and slowly clean this short -sighted, human disaster.
Whether its DDT, caustic waste, microplasty, trash or other types of waste, thinking about the ocean as a dumping of the world is the one that unfortunately is still alive and well to this day.
