The feasibility of using two different microwave-based sample preparation methods was investigated to determine the total and water-soluble trace metal fraction in airborne particulate matter. The extraction techniques were then applied to urban particulate matter of different sizes in order to evaluate their bioavailability of associated trace metals. While a combination of HNO3-HF-H2O2 was used for the total trace metal fraction of particulate matter, water was employed for the microwave… CONTINUE READING
