摘要：

The US Environmental Protection Agency's requirement that drinking water samples collected for lead analysis be acidified at the time of collection poses two problems: (1) restrictions on mailing nitric acid and (2) safety concerns associated with the possible handling of nitric acid by nontechnical persons. A study was undertaken that showed that acidification could be delayed up to 14 days and that analysis could then be carried out after waiting 28 h, without loss of lead.
