Special Substance Can Cope with Lead in the Soil

The advantage of the manganese compound tested is that it should not additionally burden the environment and is not poisonous for plants. The successful laboratory test is being verified in the field laboratory near Příbram. Within sight of the chimney, which produced contaminants in the past such as lead and zinc, the research team monitors the data from sensors measuring leakage of toxins into groundwater. The highest contamination of heavy metals is twenty centimetres below the surface. The scientists will work in the field laboratory at least another two years. Only then it will be possible to answer the question whether this sorbent captures and stabilizes heavy metals sufficiently.
