碳酸钙和粉煤灰对铅胁迫下小麦毒害的缓解效应 总被引:1,自引:0,他引:1
采用室内盆栽和网室盆栽的方法,研究了碳酸钙和粉煤灰对铅污染土壤的小麦幼苗生物效应、成熟期籽粒含铅量和蛋白质含量及生物产量的影响,探讨了碳酸钙和粉煤灰缓解铅毒害小麦的生理机制.结果表明,在轻度铅污染(铅为350 mg/kg)的小麦农田,1.0 g/kg碳酸钙或50 g/kg粉煤灰对小麦生长有明显的促进作用.能有效缓解铅对小麦的毒害;在重度铅污染(铅为600mg/kg)的小麦农田,1.0~2.0 g/kg碳酸钙或50~100 g/kg粉煤灰对小麦铅毒害缓解效果较好. 相似文献

城市环境保护满意度及案例分析 总被引:4,自引:1,他引:3
公众对城市"创建环境保护模范城市"活动的过程与结果是否认可与满意,是"创建环境保护模范城市"的最终衡量标准.针对现行环境保护满意率调查问卷存在问题.根据"创建环境保护模范城市"的目标,重新设计了调查新问卷.调查指标包括城市环境质量、政府环境保护工作等方面,采用随机抽样方法,抽取样本1 610份.结果表明,城市环境保护满意度可以作为城市环境状况和政府环境保护工作绩效的一种评估方法;满意度对人们可感知的环境质量评估效果较好;不同群体满意度间差异较大,应制定有针对性的环境保护政策,提高政策效率;城市环境保护满意度评估是对以环境质量监测数据为主的城市环境质量评估的必要补充. 相似文献

我们怀着对敬爱的周总理的深切怀念,重新刊登《让祖国的天常兰水长清》一文。从这篇文章中,我们可以清楚地看到,我们敬爱的周总理,是如何高举毛泽东思想伟大红旗,关怀我国环境保护工作的。周总理在日理万机的繁忙工作中,在强忍病痛住院治疗的时候,亲自审定我国的环境保护方针,具体、细致地指导保护环境和治理污染工作,把人民的健康,时时刻刻挂在心头。周总理不仅关怀国内的环境保护,而且一再指出在援外工程中,也应做好环境保护工作。总理的胸怀是多么广阔啊! 继承先烈志,遗愿化宏图。我们一定要把周总理对环境保护的关怀,变成我们搞好环境保护工作的坚强信念和实际行动。 相似文献

环境保护计划是国民经济和社会发展计划的重要组成部分.搞好这项工作,对于实现环境规划,发展环境保护事业起着重要作用.有人说它是环境保护工作的牵头工作,实际情况也的确如此.去年,国务院《关于在国民经济调整时期加强环境保护工作的决定》中指出:要加强国家对环境保护的计划指导,对工业布局、城镇分布、人口配置等问题进行统筹规 相似文献

Recent publicity has focused on the crisis in the market for commercial liability insurance. Industries and professionals concerned with air pollution are among those facing an acute shortage of insurance coverage. Captive insurance companies are gaining popularity as a means of securing comprehensive pollution liability coverage. Captives are separate corporations established by companies with similar risk management problems to write policies covering pollution emissions. Federal tax law requires that captives be set up properly, with transfer and distribution of risk, before premiums paid by the member companies are deductible. Financial responsibility requirements of the EPA are being redesigned, and may be favorable to the use of captives. Six states and several off-shore countries have statutes allowing captive insurance companies. Attention to practical details can lead to success in using captives to secure business advantages as well as protection from the risk of environmental impairment. Several of such considerations are discussed in light of the tax, environmental, and state regulatory issues relevant to the question, with an eye toward giving practical legal advice for structuring captives. 相似文献

In this work, 24-h PM10 samples were collected in Rio de Janeiro, Brazil, and analysed for trace elements (Cd, Ce, Cu, La, Mo, Ni, Pb, Pd, Rh, Sb and Sn). The sampling was carried out at five locations (Bonsucesso; Centro, downtown city; Copacabana; Nova Igua?u and Sumaré) with different traffic densities and anthropogenic activities. An analytical method based on the EPA method for the determination of trace elements in airborne particulate matter (PM), using ultrasonic-assisted extraction and inductively coupled plasma mass spectrometry (ICP-MS) was applied. Our results suggest that vehicular traffic is the most important source of environmental pollution at the studied sites. The presence of Mo, Pd and Rh in the analysed filters reflects an additional source of pollution caused by the erosion and deterioration of automotive catalytic converters. 相似文献

Survey and evaluation on residents' environmental awareness in Jiangsu Province of China 总被引:1,自引:0,他引:1
《国际环境与污染杂志》2011,17(4):312-322
A survey was designed to evaluate the present status of residents' environmental awareness in Nanjing and Yangzhong in China. First, it set up an index model to evaluate the level of residents' environmental awareness from three aspects: environmental attitudes, environmental behaviour and environmental knowledge. Then, the influence of individual factors on environmental awareness was analysed. The questionnaire shows that people have certain knowledge about the subject, common feelings about the severity of environmental pollution, anxiety about the effects of environmental pollution on personal health, and objection to developing the economy at the cost of environmental destruction. Most of the residents investigated showed a willingness to do voluntary work for environmental improvement. When asked for individual donations, however, some of them showed some reluctance. Some people lacked the initiative to acquire environmental protection knowledge and increase their environmental awareness. 相似文献
