重点区域环境空气质量监测方案与评价方法探讨

我国区域性大气污染问题频频发生,成为当前亟待解决的重大环境问题。区域联防联控工作需要建立相应的区域空气质量监测体系和评价方法,这对已有的监测体系提出了新的要求。在区域监测体系中需要增加臭氧、细粒子等区域性污染物及其前体物的监测,同时设立区域监控点使监测网络覆盖面由城市建成区拓展到广大近郊及农村地区。采用移动式柱浓度监测和卫星遥感监测等多样化监测手段结合超级空气站来增强区域综合监测和源解析能力。在区域内搭建监测信息共享平台和实时发布机制并建立区域空气质量预警预报系统。建立区域内统一的质量管理和质量控制方案,城市监测点质控工作由所在省市管理,区域监控点质控工作由国家统一直管。采用分区分层次的区域空气质量评价方法,评价因子包括所有六项监测指标。

HACCP原理在某醋酸装置职业病防控中的应用

目的运用危害分析与关键控制点原理对某新建醋酸装置进行职业病危害控制效果评价,探讨HACCP原理应用于建设项目职业病危害控制效果评价的科学性和实用性。方法通过对某醋酸装置的工程分析和职业卫生调查,识别各种职业病危害因素;并依据职业病危害因素检测和健康检查结果,分析其危害程度。运用HACCP原理,找出职业病危害控制的关键控制点,提出预防控制技术,并验证其效果。结果检测结果显示醋酸充装站、醋酸泵、醋酸精馏塔采样口醋酸浓度超标,醋酸外操岗位8h等效连续A声级超过85dB(A)。结论 HACCP可以运用到化工企业职业病危害防控中,为预防、控制和监督工业企业职业病危害提供科学依据。     

我国PM_(2.5)污染控制策略及环境影响评价的应对建议

分析了PM2.5对人体健康的危害以及我国PM2.5的污染现状,随后对我国和部分其它国家PM2.5的标准值进行了对比,最后从环境管理的角度出发,提出了PM2.5的控制策略,包括建立灰霾预警机制、强化源头控制、进行区域联防联控等。为了从源头控制PM2.5污染,在环境影响评价工作中,导则体系应增加PM2.5指标,环评中应加强PM2.5现状监测,重视战略环评的区域控制作用,并在项目环评中开展PM2.5影响评价。     

The Structuration of Public Participation: Organizing Environmental Control

A growing body of participation literature muses over why current mechanisms of public participation persist when they so often fail; calls for expanding the conceptual boundaries of participation beyond institutional mechanisms, and highlights the role communication, and allied concepts such as discourse and rhetoric, play in participatory processes. Given these diverse calls, environmental public participation can benefit from building a mid-level theoretical terrain. In this essay, I draw upon the sociological tradition of Anthony Giddens’ structuration theory and parallel systems thinking which foreground a structure-action mode of analysis. Through this lens I articulate the basic premises of a structuration model for environmental public participation, pointing especially to issues of agency, which involves ontological security and ontological competence, social systems, and various elements within duality of structure, with an eye toward communication-centered research. This theoretical space further indicates the possibilities of connecting the material realm of action/practice with the symbolic domain of environmental self.     

Risk taking and accident frequency among Finnish forestry workers

The results of previous studies on the relationship between risk taking and accidents have been contradictory. The aim of this study is to examine the relationship between risk taking and accident frequency among Finnish forestry workers. The subjects were 228 forestry workers whose risk taking was measured on a questionnaire with 25 items. The accident frequency was calculated based on both company-recorded and self-reported accidents. There were no significant relationships between risk taking and accident frequency. Even after elimination of age and work experience by partial correlations, there was no significant correlation between risk taking and accident frequency. Of the personality traits of the forestry workers, impulsiveness and neuroticism correlated significantly with risk taking but not with accident frequency. Two explanations for the failure to find significant correlation between risk taking and accident frequency are given.     

美国化学物质数据报告制度的经验和启示

回顾了美国《有毒物质控制法》(TSCA)中现有化学物质数据报告(CDR)制度的历史背景。介绍了CDR制度的基本内容、数据质量保证、主要修订情况,以及2012年CDR上报的化学物质数据信息汇总分析情况。针对2016年开展的新一轮CDR数据报告,总结了其最新的变化和具体要求。从建立化学物质信息收集制度、对现有化学物质进行分级管理、重点关注化学物质用途划分和归类,以及建立数据库和信息系统等4个方面,探讨了CDR制度对我国化学品环境管理的启示。     

生物泥浆反应器中微生物数量变化与PAHs降解

分别以浓度、温度、接种量、通气量和表面活性剂为降解调控因子,采用平板记数法进行了生物泥浆反应器中微生物数量变化与ＰＡＨｓ降解的关系研究。结果表明：土壤中细菌数量与ＰＨＥ、ＰＹ投加浓度呈显著正相关。ＰＨＥ、ＰＹ初始浓度越高,细菌数量越大。此外,反应器的温度对微生物生长速度和数量有重要影响。反应器温度为３０℃时对细菌迅速繁殖有利,反应器温度为２０℃时对真菌生长繁殖有利。接种量为５％即可明显提高ＰＨＥ和
