Results Inbreathe and dermal exposure to THMs in reclaimed water were the main ways of exposure for occupational worker and general populations in road clearing and public garden virescence in Beijing.

结果 再生水中氯仿、一溴二氯甲烷、二溴一氯甲烷、三溴甲烷的浓度分别为0.875~108、0.06~11.0、未检出～5.82、未检出～3.04μg/L。再生水回用于道路压尘、公园绿化，人群通过吸人和皮肤两种途径暴露于再生水，吸人暴露为主要途径，其消毒副产物THMS中。

We have developed a simple and easy-handling procedure for copper-catalyzed cyanation of aryl halides using K4[Fe_6] as the cyanide source. The present procedure has ligand- and base-free advantages, and was accomplished under the conditions of exposure to the air without degassing of the solvent.4. We carried out the selective control of preparation for phenyl ether and phenol from iodobenzene with 10 mol% of Cu_2·H_2O as the catalyst under the condition of exposure to air.
