青岛市采暖期PM2．5与大气能见度的关系

利用青岛市大气综合观测站的研究性监测数据,分析了2011年采暖期PM2.5和能见度的相关性,结果表明：①能见度在≤3km时,对应的PM2.5浓度超出0．250mg／m^3,属于严重污染;②PM2.5浓度对能见度的影响存在一临界区域,当PM2.5浓度低于该临界区时能见度会随PM2.5浓度减少迅速改善,临界值大致位于PM2.5浓度为0．100mg／m^3处;③相对湿度小于85％时,能见度与PM2.5浓度呈显著负相关。其中,相对湿度在60％-70％时,能见度与PM2.5浓度之间的相关性最好,PM2.5对能见度的影响最直接。     

化工装置停工放空过程中VOCs排放及估算方法

通过分析化工企业典型开、停车过程的排污节点,表明停车过程中大气挥发性有机污染物主要来自装置退料结束后挂壁、底部滞留和内部空间蒸气等滞留在设备内部的残余物料。在总结化工装置停工放空过程中大气挥发性有机物来源的基础上,讨论并提出大气污染排放量估算方法。

Enhancing corporate compliance with worksite safety and health legislation

Introduction: A 2-year prospective study evaluated the effectiveness of a managerial training program to enhance corporate compliance with statewide worksite safety and health regulations. The program offered participants information about regulatory requirements and emphasized organizational and environmental strategies for reducing occupational injuries and illnesses. Objectives: To assess the effects of a train-the-trainer program on business managers' knowledge of statewide occupational safety and health legislation and on levels of corporate compliance with regulatory requirements. Methods: Forty-eight small- and medium-sized companies participated in the training sessions during the first year of the study. These firms were compared with 46 control companies that did not receive the training until the conclusion of the study. Results: Participation in the program was associated with higher levels of corporate regulatory compliance 12 months after the training sessions were held (controlling for baseline levels of corporate compliance with the regulations). Program effects on compliance levels were mediated by posttraining changes in managers' knowledge of regulatory requirements. Conclusions: The REACH OUT training program raised managers' awareness of and corporate compliance with statewide worksite safety and health regulations. Impact on Industry: Smaller companies face greater challenges than larger ones in developing and maintaining worksite safety and health programs. Barriers to regulatory compliance, especially in small- and medium-size companies, should be identified and removed to enhance the efficacy of these programs.     

针铁矿及腐残质对水体重金属离子的吸附作用

采用针铁矿、腐殖质,针铁矿－腐殖复合微粒对重合微粒对重金属离子进行了吸附－解吸实验。结果表明它们对Cu^2 ,Zn^2 有强烈的吸附作用。针铁矿对Cu^2 和Zn^2 的吸附边界pH值分别为4．3和5．8,且吸附率可达95％以上。腐殖质对Cu^2 和Zn^2 的吸附边界pH值分别为4．1和5．6,且在pH值为8时,吸附率可达96％以上。针铁矿与腐殖形成的稳定复合微粒不仅对重金属离子具有良好的吸附作用,还具有均匀性好和沉降稳定的特点,可用于土壤修复和含重金属离子的污水的处理。
