摘要

在室内环境中故意释放剧毒化学品后,如果与有毒化学品本身的行为密切相关,则可以使用低毒模拟物进行现场演习,以评估补救措施。化学战剂(CWA)模拟物已根据其化学结构相似性和相关物理化学性质的适用性进行了鉴定。然而,没有报道将模拟物参数的测量结合起来的研究,如表面的持久性、采样能力和去污阶段的降解能力,从而可以量化实地演习的成功程度。使用选定数量的CWA模拟物进行了实验研究,以评估这些差距。有机磷农药马拉硫磷被发现是一种适合用于现场演习的模拟物,模拟高持久性神经毒剂VX的释放,因为它具有高持久性,使用标准分析设备进行有效的表面采样和分析,以及在不同氧化性去污剂存在下的原位降解。

Evaluation of Malathion, DIMP, and Strawberry Furanone as CWA Simulants for Consideration in Field-Level Interior Building Remediation Exercises

Evaluation of Malathion, DIMP, and Strawberry Furanone as CWA Simulants for Consideration in Field-Level Interior Building Remediation Exercises

Field-level exercises with the purpose to assess remediation following the deliberate release of a highly toxic chemical in an indoor environment can be conducted using low(er) toxicity simulants if they are closely linked to the behavior of the toxic chemical itself. Chemical warfare agent (CWA) simulants have been identified on their suitability based on chemical structural similarities and associated physical and chemical properties. However, there are no reported studies that combine measurement of simulant parameters like persistence on surfaces, ability to sample for, and capability to degrade during the decontamination phase such that the level of success of a field-level exercise can be quantified. Experimental research was conducted to assess these gaps using a select number of CWA simulants. The organophosphate pesticide malathion was found to be a suitable simulant for use in field-level exercises that simulate the release of the highly persistent nerve agent VX based on its high persistence, effective surface sampling and analysis using standard analytical equipment, and the in situ degradation in the presence of different oxidizing decontaminants.

期刊介绍: The Journal of Chemical Health and Safety focuses on news, information, and ideas relating to issues and advances in chemical health and safety. The Journal of Chemical Health and Safety covers up-to-the minute, in-depth views of safety issues ranging from OSHA and EPA regulations to the safe handling of hazardous waste, from the latest innovations in effective chemical hygiene practices to the courts'' most recent rulings on safety-related lawsuits. The Journal of Chemical Health and Safety presents real-world information that health, safety and environmental professionals and others responsible for the safety of their workplaces can put to use right away, identifying potential and developing safety concerns before they do real harm.
