摘要

Nineteen pairs of air and seawater samples collected from the equatorial Indian Ocean onboard the Shi-yan Ⅰ from 4/2011 to 5/2011 were analyzed for PCBs and HCB. Gaseous concentrations of Σ_(ICES)PCBs (ices: International Council for the Exploration of the Seas) and HCB were lower than previous data over the study area. Air samples collected near the coast had higher levels of PCBs relative to those collected in the open ocean, which may be influenced by proximity to source regions and air mass origins. Dissolved concentrations of Σ_(ICES)PCBs and HCB were 1.4-14 pg L_(-1) and 0.94-13 pg L_(-1), with the highest concentrations in the sample collected from Strait of Malacca. Fugacity fractions suggest volatilization of PCBs and HCB from the seawater to air during the cruise, with fluxes of 0.45-34 ng m~(-2) d~(-1) and 0.36-18 ng m~(-2) d~(-1) respectively.
