The heavy metals arsenic (As), cadmium (Cd), nickel (Ni), and lead (Pb) are measured as a concentration in PM10, in compliance with the CAFE Directive and 4th Daughter Directive. Filters are sampled for PM10 and then digested in the lab and analysed by ICP-MS.
The EU legislation requires that results are presented as a yearly average. The results below are presented as an average of the sampling dates so far. Check the relevant site log for additional information.
The latest available results for Heavy Metals are:
Nickel
