兰州市环境保护自身能力建设问题与对策分析

环境保护自身能力建设既是实现环境保护规划目标所应具备的物质及智力能力要素的总和,又是实现污染减排目标的重要保障。虽然兰州市环保自身能力建设取得了不少成绩,但随着兰州市经济的发展和环境污染的加剧,大气环境监测网络建设水平较低、环保信息化建设相对滞后、各县、区环境监测、监察机构标准化建设水平不高、依法管理环境的能力不强等问题就逐一凸现出来。因此,为实现新时期环保工作的各项目标,就必须采取增加环保投入、提高人员素质、加强环境监管力度、提升信息能力建设水平等措施从硬件能力建设和软件能力建设两个层面来提高兰州市环保自身能力建设水平,保证经济的可持续发展。     

Amalgam in Dentistry A Health Hazard for Dental Personnel?

In a cross sectional study done in 1993 among dental personnel in Norrbotten, self-reported prevalence of muscular pain, headache, tremor, insomnia, irritation, impaired memory and depression, as well as information regarding different mercury exposures were collected Mercury exposures were determined as “number of amalgam fillings in teeth,” “years in practice,” “insufficient ventilation at work,” “total number of amalgam removed, produced and polished per day,” and “working in dental clinics.” As controls, physicians and nurses from the same geographical area were selected. The correlation between symptoms and different mercury exposures was calculated using logistic regression. The results suggested a higher prevalence of muscular fatigue and tremor for female dental personnel compared to controls Controls reported a lower prevalence of symptoms with increasing number of amalgam fillings in teeth. There was no correlation between the number of amalgam fillings handled per day and symptoms for dental personnel. Male dental personnel associated muscular fatigue headache, impaired memory, and depression with increased handling of amalgam in the clinic’ whereas the female dental personnel associated the same symptoms with the number of amalgam fillings in teeth. The strongest correlation was found between symptoms and insufficient ventilation at dental clinics for dental personnel.
