A study was undertaken to evaluate the suitability of four types of amine modified charcoal filter canisters (cartridge) for use with gas masks (respirators) by measuring emissions of triethylamine (TEA) and diethylamine (DEA). Sampling and analysis methods for TEA and DEA were validated and optimized to ensure accurate measurement at low levels. A total of 88 air samples were taken by the validated methods to measure concentrations of TEA and DEA emitted from gas mask canisters during simulated use in an environmental chamber. Samples were collected on a mannequin equipped with a breather pump and also on human volunteers. Very low levels of TEA and moderately low levels of DEA emissions were measured during the simulations. The C7 (KOH-TEA-BPL/ASC3T) gas mask canister giving the lowest emission has been selected for use by the Canadian Forces. The potential health hazard from TEA and DEA for soldiers using the gas masks, under normal conditions, based on estimated use of one to two days per month, for a maximum of 4 hours/day for a normal working lifetime, was considered to be minimal and acceptable.
通过测量三乙胺（TEA）和二乙胺（DEA）的排放量，开展了一项研究以评估四种胺改性活性炭滤毒罐（滤芯）与防毒面具（呼吸器）配合使用的适用性。对TEA和DEA的采样及分析方法进行了验证和优化，以确保在低浓度水平下进行准确测量。采用经过验证的方法共采集了88份空气样本，以测量在环境舱模拟使用过程中防毒面具滤毒罐排放的TEA和DEA浓度。样本在配备呼吸泵的人体模型上以及人体志愿者身上采集。模拟过程中测量到TEA排放水平极低，DEA排放水平为中等偏低。已选定排放最低的C7（KOH-TEA-BPL/ASC3T）防毒面具滤毒罐供加拿大军队使用。基于每月估计使用一至两天、正常工作寿命期间每天最多使用4小时的情况，对于使用防毒面具的士兵而言，在正常条件下，TEA和DEA带来的潜在健康危害被认为极小且可接受。
