“Moss capable of removing arsenic from contaminated water has been discovered by researchers from Stockholm University. Within just one hour, it reduces water arsenic to levels harmless enough for consumption. The study has been published in the journal Environmental Pollution.

In the northern part of Sweden, water from mining areas is often contaminated by . The aquatic moss Warnstofia fluitans, which grows in northern Sweden, has the ability to quickly absorb and adsorb arsenic from water. The discovery allows for an environmentally friendly way to purify water of arsenic. One possible scenario is to grow the moss in streams and other watercourses with high levels of arsenic.

“We hope that the plant-based wetland system that we are developing will solve the arsenic problem in Sweden’s northern mining areas,” says Maria Greger, associate professor at the Department of Ecology, Environment and Plant Sciences at Stockholm University and leader of the research group.
