Abstract: | Bromoform (tribromomethane, CHBr3), one of the trihalomethanes, is a chlorination byproduct in cooling water of power plants and industrial complexes. We used the distribution of bromoform in seawater to monitor the movement of cooling water from the Youngkwang Nuclear Power Plant (YNPP) located on the West Coast of Korea. Bromoform concentrations were highest, 124 g l–1, in surface water near the outlet of YNPP and decreased linearly with distance from the outlet, mimicking the dissipation of cooling water discharged from the power plant. This byproduct of chlorination is thus a potential tracer of coastal water masses, due to its conservative behavior in the cooling water, low natural background in seawater, and easy analytical detection. |
