We reported in 2003 that exposure to metals on laundered shop towels (LSTs) could exceed toxicity criteria. New data from LSTs used by workers in North America document the continued presence of metals in freshly laundered towels. We assessed potential exposure to metals based on concentrations of metals on the LSTs, estimates of LST usage by employees, and the transfer of metals from LST-to-hand, hand-to-mouth, and LST-to-lip, under average- or high-exposure scenarios. Exposure estimates were compared to toxicity criteria. Under an average-exposure scenario (excluding metals’ data outliers), exceedances of the California Environmental Protection Agency, U.S. Environmental Protection Agency, and the Agency for Toxic Substances and Disease Registry toxicity criteria may occur for aluminum, cadmium, cobalt, copper, iron, and lead. Calculated intakes for these metals were up to more than 400-fold higher (lead) than their respective toxicity criterion. For the high-exposure scenario, additional exceedances may occur, and high-exposure intakes were up to 1,170-fold higher (lead) than their respective toxicity criterion. A sensitivity analysis indicated that alternate plausible assumptions could increase or decrease the magnitude of exceedances, but were unlikely to eliminate certain exceedances, particularly for lead.

评估洗过的毛巾可能接触到的金属。

我们在 2003 年报告说,接触到洗过的店巾 (LST) 上的金属可能会超过毒性标准。来自北美工人使用的 LST 的新数据记录了新洗过的毛巾中持续存在的金属。我们根据 LST 上的金属浓度、员工对 LST 使用情况的估计以及金属从 LST 到手、手到口和 LST 到嘴唇的转移,评估了潜在的金属暴露,低于平均水平 -或高曝光场景。将暴露估计值与毒性标准进行比较。在平均暴露情况下(不包括金属的数据异常值),铝、镉、钴、铜、铁可能会超过加州环境保护局、美国环境保护局和有毒物质和疾病登记署的毒性标准,和铅。这些金属的计算摄入量(铅)比它们各自的毒性标准高出 400 多倍。对于高暴露情况,可能会发生额外的超标,高暴露摄入量(铅)比各自的毒性标准高出 1,170 倍。敏感性分析表明,替代合理假设可以增加或减少超标的幅度,但不太可能消除某些超标,尤其是铅。
