- Data of the urban background and farm site was not available due to equipment failure on the sampling days chosen for the in vitro toxicity testing. Values of trace metals represent the total of the soluble and insoluble metal fraction. PAH, polycyclic aromatic hydrocarbon, represents the total of 18 PAHs: naphthalene, acenaphthalene, acenaphthene, fluorine, phenanthrene, anthracene, fluoranthene, pyrene, benzo(a)anthracene, chrysene, benzo(b)fluoranthene, benzo(k)fluoranthene, benzo(e)pyrene, benzo(a)pyrene, indeno(1,2,3-cd)pyrene, dibenz(a, h)anthracene, benzo(ghi)perylene, and coronene. EC, elemental carbon; OC, organic carbon. - below detection limit
