好臭氧，坏臭氧

在大气层的上部,臭氧能够起到阻挡紫外线、保护地球生命的作用,这是人尽皆知的。但是法国一家空气质量鉴定机构却指出,在今年夏天,约有1000～3000名法国人死于臭氧污染。     

极低频电磁场对健康影响的流行病学调查及人体测试研究进展

流行病学调查结果表明，环境的极低频电磁场暴露与人群某些肿瘤，如白血病、乳腺癌、脑肿瘤等，以及生殖、神经、心血管和内分泌等系统疾患的发病相关，这些结果在一定程度上得到实验室人体测试的支持。然而，极低频电磁场对健康影响的确切效应，迄今尚未能作出结论，亟等进一步开展多层次、多水平的研究。

自助加油站的静电风险及防范措施

针对自助加油发生的静电事故,分析了自助加油站的静电风险,如人体静电、加油枪出口油品静电、加油枪接地不良、油箱结构不合理等,都可能导致静电燃爆事故的发生。针对人体静电,提出使用本安型自助加油防人体静电装置和防静电加油卡;针对加油枪、加油机分别提出静电防控措施,并提出自助加油站建设的防静电建议。     

我国食品安全问题中的环境规制研究

食品安全是保障人类健康、提高人类生活品质的基础,是人类社会生存和发展的基本要素。近年来,由环境污染事件引起的农产品、渔牧产品安全问题不时发生,对人民群众的身体健康造成影响,产生了极其负面的社会影响。国外发达国家通过对影响食品安全的环境问题进行规制来保障食品安全。我国在解决食品安全问题方面做了很多努力,但是对于环境污染因素的规制还较为缺失。本文在分析了环境污染对食品安全的影响基础上,提出加强环境规制来保障食品安全是非常必要的,并结合国际经验,提出建议:完善环境相关法律,加强食品安全标准化立法;完善食品安全全过程环境监控,强化环境监管。     

An analysis on spatial variation of urban human thermal comfort in Hangzhou, China

Urban human thermal comfort (UHTC) is affected for interacting of weather condition and underlying surface framework of urban area. Urban underlying surface temperature value and Normalized Difference Vegetation Index(NDVI) were calculated using image interpreting and supervised classification technique by ERDAS IMAGE software using 1991 and 1999 Landsat TM images data. Reference to the relational standard of assessing human thermal comfort and other meteorology data of Hangzhou City in summer, air temperature and relative humidity variation of different land types of underlying surface were inversed. By choosing discomfort index as an indictor, the spatial distribution characteristic and the spatial variation degree of UHTC were estimated and mapped on a middle scale, that is, in six districts of Hangzhou. The main characteristics of UHTC spatial variation from 1991 to 1999 were revealed using a GIS-based calculation model. The variation mechanism were analyzed and discussed from the viewooint of citv olannino, construction and environmental orotection.

Combined toxicity of copper and cadmium to six rice genotypes （Oryza sativa L.）

Accumulation of copper (Cu) and cadmium (Cd) in six rice cultivars (94D-22, 94D-54, 94D-64, Gui630, YY-1 and KY1360) was evaluated through exposure to heavy metal contamination (100 mg/kg Cu, 1.0 mg/kg Cd, and 100 mg/kg Cu + 1.0 mg/kg Cd) in a greenhouse. The dry weight of shoot and root, concentrations of Cu and Cd in plant tissues and the Cu, Cd, P, Fe concentrations in the root surface iron plaques were analyzed eight weeks later after treatment. The results indicated that the plant biomass was mainly determined by rice genotypes, not Cu and Cd content in soil. Separated treatment with Cu/Cd increased each metal level in shoot, root and iron plaques. Soil Cu enhanced Cd accumulation in tissues. In contrast, Cu concentrations in shoot and root was unaffected by soil Cd. Compared to single metal contamination, combined treatment increased Cd content by 110.6%, 77.0% and 45.2% in shoot, and by 112.7%, 51.2% and 18.4% in root for Gui630, YY-1 and KY1360, respectively. The content level of Cu or Cd in root surface iron plaques was not affected by their soil content. Cu promoted Fe accumulation in iron plaques, while Cd has no effect on P and Fe accumulation in it. The translocation of Cu and Cd from iron plaques to root and shoot was also discussed. These results might be beneficial in selecting cultivars with low heavy metal accumulation and designing strategies for soil bioremediation.
