我国节约能源法将于2008年4月1日正式实施

节约能源法修订案在法律层面明确提出:"国家实行节约资源的基本国策,实施节约与开发并举、把节约放在首位的能源发展战略."全国人大财经委主任委员、节能法修订起草组组长傅志寰说,此次修订完善了节能的基本制度,注重发挥市场机制的作用,同时强化政府监管.     

突出重点扎实工作 整体推动水环境保护迈上新台阶——周生贤部长就《水污染防治法》答记者问

于今年2月28日修订后颁布的《水污染防治法》已于6月1日起正式实施。记者就《水污染防治法》的修订情况及下一步如何贯彻落实等问题专访了环境保护部部长周生贤。     

回顾标准发展历程探寻国际管理经验之美国篇:臭氧(O_3)和碳氢化合物(HC):考虑的关键因素是什么?

美国在1971年首次制定臭氧环境空气质量标准,并于1997年和2008年进行过2次修订.1971年首次制定的标准是以光化学氧化剂(以臭氧计)为基准空气污染物,仅规定了1h平均浓度限值为160μg/m3.一级和二级标准相同.     

Impacts of wastewater sludge amendments in restoring nitrogen cycle in p-nitrophenol contaminated soil

The possible impacts on nitrogen-cycle in a p-nitrophenol (PNP) polluted soil and the e ectiveness of wastewater sludge amendments in restoring nitrification potential and urease activity were evaluated by an incubation study. The results indicated that PNP at 250 mg/kg soil inhibited urease activity, nitrification potential, arginine ammonification rate and heterotrophic bacteria counts to some extents. After exposure to PNP, the nitrification potential of the tested soil was dramatically reduced to zero over a period of 30 days. Based on the findings, nitrification potential was postulated as a simple biochemical indicator for PNP pollution in soils. Nitrogen-cycling processes in soils responded positively to the applications of wastewater sludges. A sludge application rate of 200 tons/ha was su cient for successful biostimulation of these nitrogen processes. The microbial activities in sludge-amended, heavy PNP-polluted soils seemed to recover after 30–45 days, indicating the e ectiveness of sludge as a useful soil amendment.

对修订后《水污染防治法》第七十三、七十四条如何执行的疑惑与思考

本文主要介绍了在执行新修订的《水污染防治法》中遇到的一些疑惑,并对如何更好地执行提出了几点建议。     

Enhanced and irreversible sorption of pesticide pyrimethanil by soil amended with biochars

Biochar derived from partial combustion of vegetation is ubiquitous and potentially effective in sequestration of environmental contaminants.Biochars were prepared by burning of red gum(Eucalyptus spp.) woodchips at 450 and 850°C(labeled as BC450 and BC850).These two biochars were found to possess markedly different properties in terms of surface area and porosity.Short-term equilibration tests(24 hr) were conducted to assess the sorption-desorption behavior of pyrimethanil in the soil amended with various amounts of biochar of each type,with a special focus on the desorption behavior of the sorbed pesticide through four times successive desorption by dilution.Sorption coefficient and isotherm nonlinearity of the amended soils progressively increased with the content of biochar in the soil.Biochar BC850 with higher surface area and microporosity showed a stronger effect on the reversibility of sorption pesticide.The soils amended with 5% BC450 and 1% BC850 had nearly the same sorption capacity for pyrimethanil;however,their desorption processes were very different with 13.65% and 1.49% of the sorbed pesticide being released,respectively.This study suggested that biochar in soil could be an important factor for immobilization of a pesticide and thus affecting its environment fate in soil.     

必须重视石油化工企业专职安全管理人员的在职教育

1在职教育的必要性和现状 1.1在职教育的必要性 石油化工企业的安全管理既是一项专业管理也是一项综合管理,作为专项管理,它需要安全管理人员具备安全工程、安全技术、安全心理等方面的知识;其综合管理的一面,还必须懂得工艺和设备知识.安全检查和"三同时"审查,是依据国家标准和规范来进行,安全管理人员还必须熟悉有关的国家标准和技术规范.所以石油化工企业对于专职安全管理人员的要求,已经不再是以往的只会照章检查,仅能指出不足之处的单一功能的安全管理人员,而是需要"复合型"的专职安全管理人员.     

关于环境保护法律法规修订的新观点

为了保护人类健康不受恶劣环境的侵害,就必须对依法保护环境进行相关研究。提出了环境与健康是人类健康生存头等大事的观点,总结中国主要环境保护法律法规的不足,提出新的修订措施。提出6条保护环境的新法规建议供环境保护法修订时参考应用,主要包括:1)环境与健康及保护法规的宣传教育立法;2)医疗卫生机构设立环境医学防治学科立法;3)国家普及设立环境污染监测和预报系统立法;4)人民政府环境保护行政主管部门应扩展和延伸立法;5)国家在任何单位均应设立环境污染保护行政主管科室立法;6)国家设立外国在华企业环境保护行政主管部门立法。
