 For instance, in one trial, it was found that M. x giganteus absorbed 52% of the lead content and 19% of the arsenic content in the soil after three months.The absorption stabilizes the pollutants so they don't travel into the air (as dust), into ground water, neighbouring surface waters, or neighbouring areas used for food production.If contaminated miscanthus is used as fuel, the combustion site need to install the appropriate equipment to handle this situation.
