摘要

This communication presents the probable sampling and preservation artifacts in arsenic analysis of natural groundwater. It has particularly scrutinized the standard method of sampling and preservation of arsenic, where the sample is to be acidified with concentrated HNO3 until a pH of less than 2. It has also ascertained the efficacy of sample container material in preserving the original arsenic concentration. Arsenic losses due to preservation imperfections will adversely affect the results and their interpretation from the public health point of view. The communication also discusses that proper sampling and preservation could be the most neglected part of the whole regulation and could be the cause of under-reporting of arsenic contrasted with a higher incidence of arsenic ailments in the population, particularly in the Third World.
