Specifies the determination of mercury in two parts which use either tin(II)chloride or sodium tetrahydroborate as reducing agent. The methods described in clauses 4 and 5 are suitable for the determination of mercury in water, for example in ground, surface and waste waters, in the concentration range from 0,01 µg/l to 1 µg/l. Higher concentrations may be determined if the water sample is diluted. The total mercury content of water is determined after digestion of the sample. If only soluble mercury compounds are to be determined, a filtration step using a 0,45 µm membrane filter is applied prior to digestion.
