According to Newman’s a professor of biotechnology and phytoremediation at the State University of New York in Syracuse algae could help to clean the area near Fukushima Daiichi. Phytoremediation is a process of cleaning the environment with the use of plants. And that is where algae come in. This area is not completely known but it is rapidly developing.

Three years ago, a territory in Japan has been swept down due to the earthquake and tsunami. As a result of that, the nuclear power plant has been crashed and since then it is leaking radiation straight into the ocean endangering lives of both Japanese and international community.

Cleaning up the area and water is a long and complicated process. Japanese government is using various possible means to deal with the situation. Now the scientists came up with an idea that phytoremediation could help.

Phytoremediation is a process of cleaning the environment with the use of plants. And that is where algae come in. This area is not completely known but it is rapidly developing.

“There’s been quite a bit of research in this area looking at heavy metals, pesticides, chlorinated solvents, explosive compounds and radioactive compounds,” Newman says.

It has been established that certain plants can suck up the chemical substances, such as cesium and strontium, which are produced by nuclear plants. Algae exist in Japan and there have already been studies by Japanese scientists, like Yoshihiro Shiraiwa, a professor of plant physiology and metabolism and provost of the faculty of life and environmental sciences at Japan’s University of Tsukuba.

He along with his team tested 200 species of local microalgae and they have chosen one specific strain that is the most effective at cleaning the area.

“In our test,” Shiraiwa says, “more than 90 percent of radioactive cesium was removed by this microalgae.”
