As workers in medicine, food science, and advanced manufacturing have learned, pristine disposable gloves are an innate source of chemical contamination from the moment they are first donned. Given the typically low extent of chemical contamination on the surface of gloves post-manufacture, many fields overlook, or simply discount, this source of transferable chemical evidence. However, forensic science should not adopt this approach. Instead, the trace chemical signatures left after handling objects while wearing different brands and types of disposable gloves could provide new avenues of forensic intelligence when assessing crime scenes. Similarly, an appreciation of the potential for disposable gloves to transfer innate chemical residues is an important consideration when surface analyses of evidence are envisioned. This review summarises past reports of chemical transference originating from pristine gloves drawn from the fields of medicine, food science, and material science, as well as the few examples highlighting the implications of such events for forensic investigations. Correlations between the chemical identities of the contaminants and the material of glove manufacture are provided here where known, with energy-intensive chemical extraction of glove material, and passive transference of chemical residues through simple contact, both explored. Finally, discussions pertaining to the implications of disposable glove residues, coupled with opportunities for future research, are outlined.
正如医学、食品科学和先进制造业的工作人员所了解的那样，从一次性手套首次使用的那一刻起，它们就是化学污染的固有来源。鉴于手套在制造后表面的化学污染通常程度较低，许多领域忽略或简单地排除了这种可转移化学证据的来源。然而，法医学不应采用这种方法。相反，在处理物体时戴不同品牌和类型的一次性手套后留下的痕量化学特征，可以为评估犯罪现场提供新的法医学线索。同样，当设想对证据进行表面分析时，应该充分认识到一次性手套可能转移固有化学残留物的潜力。本综述总结了过去来自医学、食品科学和材料科学领域的关于原始手套中化学转移的报告，以及少数几个突出此类事件对法医学调查影响的例子。在这里，提供了已知的污染物化学性质与手套制造材料之间的相关性，同时还探讨了通过能量密集型化学提取手套材料和通过简单接触被动转移化学残留物的情况。最后，概述了与一次性手套残留物相关的影响以及未来研究的机会。
