Studied volatile species, including their structure and boiling points, calculated total trapping efficiencies, and observed reactions products and structures after trapping and transformation in concentrated nitric acid.

aBoiling point at 1 atm befficiency using a 30 mL·min−1 N2 gas flow, summed over three impingers, standard deviation from triplicate experiments.Abbreviations: dimethyl selenide (DMSe), dimethyl diselenide (DMDSe), dimethyl sulfide (DMS), dimethyl disulfide (DMDS), monomethyl arsine (MMA), dimethyl arsine (DMA), trimethyl arsine (TMA), dimethyl selenoxide (DMSeO), methane seleninic acid (MSeA), dimethyl sulfoxide (DMSO), methane sulfonic acid (MSA), arsenate (As[V]), monomethyl arsonic acid (MMAA).

1大气压下的效率测定采用30 mL·min⁻¹的氮气气流，结果以三个冲击式采样瓶的总检测值计，数据为三次重复实验的标准偏差。缩写说明：二甲基硒（dimethyl selenide, DMSe）、二甲基二硒（dimethyl diselenide, DMDSe）、二甲基硫（dimethyl sulfide, DMS）、二甲基二硫（dimethyl disulfide, DMDS）、一甲基胂（monomethyl arsine, MMA）、二甲基胂（dimethyl arsine, DMA）、三甲基胂（trimethyl arsine, TMA）、二甲基亚硒砜（dimethyl selenoxide, DMSeO）、甲烷亚硒酸（methane seleninic acid, MSeA）、二甲基亚砜（dimethyl sulfoxide, DMSO）、甲烷磺酸（methane sulfonic acid, MSA）、砷酸盐（arsenate, As[V]）、一甲基胂酸（monomethyl arsonic acid, MMAA）。
