浙江省环境放射性监测站与秦山核电厂辐射环境测量比对

本文介绍国家环保局为验证秦山核电厂的辐射环境监测数据而安排的比对测量结果，比对范围涉及秦山核电厂常规监测的主要项目和核素，比对双方为浙江省环境放射性监测站与秦山核电厂。比对结果表明：除土壤中γ核素，水体中＾３Ｈ和气溶胶中＾９０Ｓｒ的双方数据存在明显偏差外，其余符合较好。     

How much does Environmental Tobacco Smoke Contribute to the Building Symptom Index?

Environmental tobacco smoke (ETS) has been identified as one of the factors associated with the symptoms of the sick building syndrome (SBS). We investigated the role of ETS in an office building during the phased introduction of a smoking ban. Over a two-year period we measured symptoms using a validated questionnaire, environmental nicotine levels and salivary cotinine as a biological marker of nicotine absorption in a stratified systemic sample of 375 office employees (91% response rate). In addition, 26 persons from a non-smoking office were studied as a control group. This report describes the findings derived from a cross-sectional analysis of the initial baseline data. Amongst the validated nonsmokers, symptoms increased with increasing nicotine exposure from ETS (r= 0.165 p < 0. 01), supporting the role of ETS in the SBS. Smokers reported significantly fewer symptoms than non-smokers, as has been found before, but were exposed to higher levels of airborne nicotine as expected. We suggest that this factor, along with the misclassification of smoking status, may have obscured an association between ETS exposure and the SBS in previous studies. An analysis of the findings after implementation of the smoking ban should provide further information on how much of the SBS is attributable to ETS in this study population.     

环境安全的合成基钻井液

合成基钻井液是国外90年代出现的新型钻井液,其各项性能与油基钻井液相近,普遍优于水基钻井液,能提高钻速,缩短钻井时间,降低钻井总费用,还能避免环境污染,特别适用于海上钻井。目前已开发并使用过的合成基钻井液有酯基钻井液、聚α-烯基钻井液和醚基钻井液。
