A first long-term (2 years) field experiment indicated how As and other metal(loid) contaminants can be released from As-rich copper smelter flue dust after deposition in contrasting soils. Up to 72% of As was leached out from the flue dust after incubation. The majority of As became highly mobile and could represent a risk for individual environmental compartments (soil, water).
