| Abstract: | The long-term storage behavior of mercury and methylmercury at ng 1?1 levels in sea water was studied at pH 4.0, 6.0, 8.0 and 10.0, and with 2% (v/v) hydrochloric or nitric acid added. Partial complexation and disappearance of mercury and methylmercury were observed; some of the lost mercury became detectable (by cold-vapour atomic absorption spectrometry) after prolonged storage. |
