鞍山城市声环境现状及控制对策

利用功能区噪声环境监测资料,计算分析了鞍山市区声环境现状。结果表明：2012在鞍山市区,各功能区噪声超出国家标准,对声环境的影响以社会生活噪声和交通噪声以及鞍钢生产所产生的工业噪声为主。结合鞍山市实际情况提出了一系列监管、治理、防范等措施减少噪声污染。     

鞍山市区电磁辐射污染特征分析

电磁辐射污染时伴随着社会的发展、工业化的进步而产生的。鞍山作为一个大型工业化城市,电磁辐射设施种类和类别较多,这种污染几乎无处不在,长期以来,人们对电磁辐射污染缺乏了解,鞍山市区电磁辐射监测数据资料匮乏。从保护市民群众身体健康角度,结合国家相关法规及监测依据,制定一套合理可行的监测方案,针对鞍山市电磁辐射污染进行全面研究,深入了解鞍山市区电磁辐射污染现状,通过监测数据研究提出相应的保护建议,避免伤害的发生。     

“水污染防治行动计划”实施背景下我国水环境管理优化对策研究

针对我国日益凸显的水资源过度开发、水环境污染、水资源短缺、用水效率与效益低下等水危机,对我国近年来出台最严格水资源管理制度、"水污染防治行动计划"(称"水十条")等水资源管理、水环境保护相关政策与研究进展及国外在水环境管理方面经验进行了探讨。分析了"水十条"实施后在水资源管理、水生态安全、法律法规与执法监管、资金投入与激励机制、技术推进与公众参与等需解决的关键问题与推进重点工作,提出具体措施包括以协作机制优化区域流域水环境管理,完善水权交易并规范绿色投融资体系,创新水文化建设与公众参与模式,优化分区、分级、共治的水环境管理法规与执法支撑体系,强化信息化、集成化的水环境管理与应用等。

Research progress of disinfection and disinfection by-products in China

Disinfection is an indispensable water treatment process for killing harmful pathogens and protecting human health. However, the disinfection has caused significant public concern due to the formation of toxic disinfection by-products(DBPs). Lots of studies on disinfection and DBPs have been performed in the world since 1974. Although related studies in China started in1980 s, a great progress has been achieved during the last three decades. Therefore, this review summarized the main achievements on disinfection and DPBs studies in China, which included:(1) the occurrence of DBPs in water of China,(2) the identification and detection methods of DBPs,(3) the formation mechanisms of DBPs during disinfection process,(4) the toxicological effects and epidemiological surveys of DBPs,(5) the control and management countermeasures of DBPs in water disinfection, and(6) the challenges and chances of DBPs studies in future. It is expected that this review would provide useful information and reference for optimizing disinfection process, reducing DBPs formation and protecting human health.

STATE WATER QUALITY CONTROL PROGRAM IN ARIZONA1

ABSTRACT: Arizona's water pollution control program is based on authorties of Arizona Revised Statutes and Public Law 92–500, the Federal Water Pollution Control Act Amendments of 1972. The primary areas of this program are monitoring, facility inspections, plan review, planning, discharge permits and grants for the construction of publicly-owned waste water treatment facilities. The discharge permit program deals with control of point-source discharges and is administered by the United States Environmental Protection Agency. The planning and construction grants programs are administered by the State Water Quality Control Council and are implemented by the Bureau of Water Quality Control, which serves as staff to the Council. There are several challenges that face the State in this program. First is the adaptation of the “eastern law” to deal with Arizona's water quality problems. Second is to address problems caused by a long history of “laissez-faire” environmental quality management. Third is a mutual cooperation and coordination among the many entities involved in water resources management. Areas of particular interest in the State's program is the process setting water quality standards and the involvement of people of diversified backgrounds in the field of areawide planning under Section 208 of the Federal Water Pollution Control Act, which is primarily concerned with non-point sources of water pollution.
