炼厂产生的烟气含有大量的有害污染物,主要有一氧化碳、氮氧化物、硫氧化物和颗粒物等。发达国家和一些发展中国家对固定污染源污染物的允许排放量限制日益严格。违反排放标准的炼厂将依照国家规定受到严厉处罚。炼厂环境控制技术是一项价值达数十亿美元的经营业务。相关的技术提供商为数众多,分布于世界各地。控制硫氧化物、氮氧化物、颗粒物和挥发性有机化合物排放的主要技术大部分掌握在美国、西欧和日本的企业手中。环境控制通用技术主要有用于控制硫氧化物和颗粒物排放的烟气净化技术（再生器烟气洗涤器）、控制颗粒物的静电除尘器（e.P）系统、用于控制氮氧化物的选择性催化还原（SCR）和选择性非催化还原（SNCR）技术、用于控制氮氧化物的低/超低氮氧化物燃烧器、用于控制挥发性有机污染物的放空燃烧系统。炼厂催化裂化装置和硫磺装置专用的环境控制技术有借助添加剂降低催化裂化再生器的排放技术、降低硫磺装置硫氧化物和颗粒物排放的技术（改进的克劳斯工艺——富氧克劳斯工艺、亚露点克劳斯工艺、直接氧化克劳斯工艺）。炼厂应充分把握当前的污染防治和减排技术趋势及未来发展机会,根据技术的成本分析选择最佳技术,以最低的成本实现环保达标。

本文对《欧洲全科医学/家庭医学和基本医疗保健科研纲要》的中文译稿进行了重点摘登。该文件由欧洲全科医学科研网络制订,包括7部分内容:序言、导言、方法、结果、独立章节,讨论和启示。作为在欧洲发展全科医学科研的核心指南,该文件对欧洲的全科医学学科和科研发展产生了深远的影响。欧洲的全科医学体系和以此为基础而构建的学科理论共识与我国全科医学当前的实际情况可能更为接近。因篇幅所限,本文刊登了其中最重要,对中国研究者也最实用的5部分内容,包括:(1)导言——全科医学的核心能力/特征以及全科医学科研的意义;(2)结果——全科医学的6个核心领域(基本保健管理、"以人为本"的照护、解决具体问题的技能、综合的方法、以社区为导向、整体的方法)的科研范畴,研究需求和适用方法;(3)独立章节——如何发展基本的科研能力和避免常见的科研失误;(4)讨论——未来的全科医学科研重点;(5)启示——科学协会、研究机构、患者参与、科研工作、期刊、科研政策在发展学科方面应注重的问题。因欧洲的全科医学体制和我国较为相似,且存在一定的科研发展代差,该文件在当前阶段也可为我国全科医学研究者所用,基于全科医学学科的视角,从概念、分类学、范围和科研方法等方面,为我国全科医学科研的发展提供参照。

Background: Se.0}ral studie. have de.onstrate. that e.waste.worke.s had a risk to de.0}lop the.re.piratory disorde.s but this was not spe.ifically diffe.e.tiate. according to the.type.of the.e.waste.activitie.. The.main aim of this study was to e.aluate.if the.risk to de.0}lop re.piratory disorde.s was diffe.e.t according to the.type.of activitie. carrie. out by the.e.waste.worke.s. methods: A cross se.tional study was conducte. in Abidj.n and Cotonou, two big citie. in We.t Africa. The.participants we.e.randomly se.e.te. base. on the.list of e.waste.worke.s provide. by the.ce.sus of diffe.e.t site. of e.waste. The.spirometry was pe.formed on all the.study participants to asse.s whe.he. the. had re.piratory disorde.s. A re.re.sion logistic mode. was pe.formed to e.timate.the.risk of de.0}loping re.piratory disorde.s according to the.type.of activitie. carrie. out by the.e.waste.worke.s. Re.ults: In total 308 e.waste.worke.s including 149 at Abidj.n and 159 at Cotonou we.e.inte.vie.e.. Participants of this study range. in age.from 14 ye.rs to 69 ye.rs and the.mean age.was 33.71 ± 10.96. The.main activitie. carrie. out by the.study participants we.e.re.pe.tively re.airing (44.8%), buying or se.ling (40.3%), dismantling (31.8%). The.pre.ale.ce.of re.piratory disorde.s was 20.1%. The.multivariate.analysis had not found a significant association be.we.n the.type.of activitie. and the.pre.e.ce.of re.piratory disorde.s. Conclusion: The.e.fe.t of e.posure.to e.waste.on re.piratory he.lth of worke.s was not diffe.e.t according to the.type.of activitie.. So, any policy that aims to re.uce.the.risk of e.posure.on re.piratory he.lth must take.into account all the.e.waste.worke.s re.ardle.s of the.type.of activitie. the. pe.form in this se.tor.
