[Assessment of an extraction-photometric method of determining mercury in urine]

Experimental trials of the extraction photometry of the urine mercury have shown that this method is not sensitive enough to detect the mercury concentrations in human urine in health. Even if the mercury concentrations are detectable with this method, the results are unrepeatable because of the inadequacy of the extraction technique. This makes extraction photometry unacceptable for measuring the urine mercury concentrations at clinical laboratories.
