In this study, 10 mosquito coils manufactured in China were obtained in Suriname, South America, where they are used extensively. The coils were analyzed for organics (allethrin, permethrin, and butylated hydroxytoluene) and heavy metals (Cr, Co, As, Cd, and Pb) by GC-MS and ICP-MS, respectively. Allethrin was the only target organic compound detected in all mosquito coils with concentrations ranging from ~1900 to ~4500 µg/g. The concentrations of heavy metals varied as follows (in µg/g): Cr: 2.9-9.4, Co: 0.1-1.2, Cu: 0.7-16.1, Se: 0.10-0.4, Ni: 2.1-5.8, As: 0.10-2.2, Cd: 0.10-0.2, and Pb: 1.1-3.6.
在本研究中,从南美洲苏里南收集了10种中国制造的蚊香,当地广泛使用这些蚊香。分别通过气相色谱 - 质谱联用仪(GC-MS)和电感耦合等离子体质谱仪(ICP-MS)对蚊香中的有机物(炔丙菊酯、氯菊酯和丁基化羟基甲苯)和重金属(铬、钴、砷、镉和铅)进行分析。在所有蚊香中检测到的唯一目标有机化合物是炔丙菊酯,其浓度范围约为1900至4500μg/g。重金属浓度变化如下(单位:μg/g):铬:2.9 - 9.4,钴:0.1 - 1.2,铜:0.7 - 16.1,硒:0.10 - 0.4,镍:2.1 - 5.8,砷:0.10 - 2.2,镉:0.10 - 0.2,铅:1.1 - 3.6。
