Lima, Jan 5: 

Those who are worried over the pollution of lakes in Bengaluru can try to contact this scientist who has done a wonderful job in reviving polluted wetlands in Peru in just 15 days using nanotechnology and has now planned to clean up the famous Lake Titicaca at Peru-Bolivia border and Huacachina lagoon which is located in the middle of a desert in Peru.

   마리노 모리카와 박사는 자신이 개발한 나노 기술로 페루의 오염된 호수를 청정지역으로 만드는 모습을 보여주고 있다.

그는 며칠 동안에 걸쳐 페루의 오염된 습지를 복구했다.

벵골루 호수의 오염에 대해 우려하는 사람들은 나노기술을 이용해 페루의 오염된 습지를 되살리기 위해 15일 만에 일을 훌륭하게 해냈고, 현재는 페루-볼리비아 국경에 있는 유명한 티티카 호수와 페루의 사막 한가운데 있는 후아카치나 석호를 청소할 계획이다.

마리노 모리카와 스페인 통신사 아겐시아 EFE에 관한 보고서에 따르면 마리노 모리카와는 리마 북쪽에 위치한 샹카이 지역의 약 50헥타르를 포함하는 생태계의 엘 카스카조에게 2010년에 회복될 수 있도록 도와준 두 가지 발명기술을 내놓았다. 모리카와는 그 환경사업을 위해 자신의 자원과 돈을 마련했다. 엘 카스카조를 복원한다는 생각은 어렸을 때 낚시를 하러 간 곳이며 수질 상태가 매우 안 좋았다고 모리카와가 EFE에게 말했다.

Marino Morikawa According to a report on Spanish news agency Agencia EFE, Marino Morikawa came up with two inventions that helped El Cascajo, an ecosystem covering roughly 50 hectares in Chancay district located north of Lima, to undergo recovery in 2010. Morikawa came up with his own resources and money for the cause. The idea of restoring El Cascajo came from a call from Morikawa's father who told him that it was there where they went for fishing when the scientist was a child and that it "was in very bad condition," Morikawa told EFE. 

Morikawa, who has a degree in environmental science from Tsukuba University in Japan, visited the wetlands and "found a dump for sewage ringed by an illegal landfill where migratory birds fed" and the swamp was covered by water-borne plants.

"Morikawa set out to find a way to decontaminate the wetlands without using chemicals, and his first invention was a micro nanobubbling system, which consists of bubbles 10,000 times smaller than those in a soda beverage and remain in the water between four and eight hours," the EFE report said. Morikawa later said the bubbles trap and paralyses viruses and bacteria, destroy them as well as make them evaporate.

He also designed biological filters with clay to retain the inorganic pollutants that adhere to the surfaces. The results began to show in a fortnight which otherwise would have taken six months to get fulfilled in laboratory. Morikawa gave Nature its due saying he only gave it a boost to speed up the recovery process. The wetlands were soon populated by migratory birds that used to throng El Cascajo earlier while flying from Canada to Patagonia. Morikawa then helped recovery of 30 habitats around the world and now eyes recovery of Lake Titicaca, the largest lake in South America located at a height of over 13,000 feet above the sea level.
