公路工程施工期的环境保护监理

对于生态影响较大的项目,重点发生在施工建设期,为了有效地控制工程施工阶段的生态环境影响和环境污染,开展公路工程施工期的环境保护监理工作尤其重要。本文结合工程环境监理工作实践,简要分析了公路工程施工期的环境保护监理要点。     

Friends and family vs. government: who does the public rely on more to prepare for natural disasters?

This paper examines what organizations and groups individuals rely on to help prepare for natural disasters and how reliance differs vis-à-vis demographic characteristics. Using data gathered from 2,008 individuals employed in the United States, the results revealed that individuals are significantly more likely to rely on friends and family than government organizations at the local, state, and federal level. The findings also suggest that this reliance varies across demographic groups. For example, data from the present study suggest that women and minority groups as well as individuals who are older and less educated are significantly more likely to rely on organizations to help prepare for natural disasters. This study contributes to the disaster management and risk communication literatures by offering key insights into the organizations and groups the American public in general, and certain demographic groups in particular, rely on when it comes to preparing for natural disasters. Knowledge about the organizations and groups that individuals rely on to help prepare for natural disasters can help policymakers and practitioners target those organizations as conduits to deliver critical preparedness information, as well as other information related to disaster mitigation, response, and recovery.     

What kinds of injuries do OSHA inspections prevent?

Objective

OSHA's enforcement program is one of the major public efforts to protect American workers. We examine both the scope of injury prevention that inspections can contribute and the types of standards that contribute the most.

Methods

We linked Pennsylvania Department of Labor and Industry files for lost-time injuries and employment to calculate injury rates for 1998-2005 for all single-establishment manufacturing firms. We linked these to OSHA inspection records.

Results

Inspections with penalties did affect injury types unrelated to standards as well as those related. We also found again that citations for violations of the standard requiring personal protective equipment had the largest impact on preventing injuries.

Impact on Industry

Programs requiring protective equipment use deserve added attention from consultants and inspectors. In addition, some inspections spur managers to undertake safety measures that go beyond compliance with standards.     

2014年1月沪渝高速公路汉宜段一次大雾个例分析

对2014年1月29~31日发生在沪渝高速公路湖北武汉—宜昌段(简称汉宜高速公路)的封路大雾过程气象要素进行分析。结果表明:(1)此次持续大雾过程发生时,近地层有逆温,地面处于高压底部前端的均压场,中纬度维持偏西气流,为大雾的形成和发展提供了有利的环流背景场条件;大雾消散后,地面处于冷高压控制;2)大雾造成的高速公路封路、解封前后,气象要素发生了较明显的变化。这些分析结果,对汉宜高速公路的大雾预警预报具有较好的指示意义。     

废弃电池能否进入废弃电器电子产品处理目录(第二批)管理的筛选评估分析

2009年2月,国务院发布《废弃电器电子产品回收处理管理条例》,成为我国废弃电器电子产品回收处理的纲领性文件。在《废弃电器电子产品处理目录(第一批)》中,明确将电视机、电冰箱、洗衣机、房间空调器、微型计算机等5种产品纳入第一批目录。同时,为了为了能够及时、客观地与经济发展、技术进步以及电器电子产品行业的发展变化等相适应,《目录》管理委员会起草了《制订和调整废弃电器电子产品处理目录的若干规定》,明确随着经济发展变化及电子产品废弃形势调整电器电子产品处理目录的原则。废弃电池在近几年来在我国增长速度很大,将来的管理形势十分紧迫。本文在此分析我国几种废弃电池(铅酸电池、镍氢电池及锂电池)的产生量、再生处理处置情况及管理政策导向。并在目录一批筛选原则的基础上利用权重分析法,筛选评估废弃电池能否进入废弃电器电子产品处理目录(第二批)管理的可能,研究显示铅酸电池已具备进入管理目录的资质。     

Low dose effects and non-monotonic dose responses for endocrine active chemicals: Science to practice workshop: Workshop summary

A workshop was held in Berlin September 12–14th 2012 to assess the state of the science of the data supporting low dose effects and non-monotonic dose responses (“low dose hypothesis”) for chemicals with endocrine activity (endocrine disrupting chemicals or EDCs). This workshop consisted of lectures to present the current state of the science of EDC action and also the risk assessment process. These lectures were followed by breakout sessions to integrate scientists from various backgrounds to discuss in an open and unbiased manner the data supporting the “low dose hypothesis”. While no consensus was reached the robust discussions were helpful to inform both basic scientists and risk assessors on all the issues. There were a number of important ideas developed to help continue the discussion and improve communication over the next few years.
