| Popis | On Zugspitze (2670 m a.s.l.), Alps, higher concentrations were observed during a winter than during a summer measurement campaign of PAHs, chlorobenzenes (43.6 vs. 2.0 pg/m3) and DDTs (3.7 vs. 1.2 pg/m3), while hexachlorocyclohexanes and PCBs were found at similar levels. The PCB, HCH and DDT levels are among the lowest ever reported from outside the Arctic. Photochemical lifetimes corresponding to kOH < 1.5 are found for ppDDT, kOH < 0.75 for ppDDE and kOH < 1.0 (1012 cm3/molec/s) for ppDDD. |
