The oil industry is one of the main productive activities in Mexico and has a huge infrastructure, including a wide pipeline network that crosses urban, industrial, agricultural and natural areas. The threat of crude oil spills is greatest in those regions with a high concentration of oil extraction and refining activities, as in the case of the Coatzacoalcos and Tonalá Rivers Low Basin. This study ranked the geosystems of the basin in terms of vulnerability to pipeline crude oil spills. Very high vulnerability (level I) was assigned to the water bodies (lakes and rivers) and their margins of influence, including surfaces that flood during normal hydraulic load. High vulnerability areas (level II) comprised surfaces that can flood during extraordinary hydraulic load related with extreme hydrometeorological events. The remaining three vulnerability levels were defined for areas with low or negligible flooding potential, these were ranked according to physical (slope, relief and permeability), biological (richness, singularity and integrity) and socio-economic (social marginalization index and economic activities index) conditions. These results are presented on a map for better visualization and interpretation. This study will be useful to establish preventive and effective emergency management actions in order to reduce remediation costs and adverse effects on wild species. It also can help local and national authorities, oil industry and civil protection corps to better protect ecosystems, natural resources and human activities and goods. 相似文献

Solid waste management is one of the challenging problems worldwide and it is becoming more complex by the increase in population and subsequently the waste generated. In Malaysia, among industrial solid waste palm oil mill waste (POMW) contributes the highest share. Wastes from the oil palm mill includes palm oil mill effluent (POME), decanter cake, empty fruit bunches, seed shells and the fibre from mesocarp. Generally most of the waste generated is either disposed of via open dumping or used as fertilizers as such or as animal feed. Land application of POMW and POME is very common practice as it contains numbers of plant nutrients. Direct application of POMW into agricultural soil can result in a number of problems such as water pollution, leaching etc. To deal with these problems, vermicomposting of palm oil mill waste may be a sustainable waste management option.There are number of researches going on management of biomass residues from palm oil mill, but very few works are going on vermicomposting of these agro-industrial waste. Vermicomposting of POMW can be a good practice as it will also be helpful in recycling the useful plant nutrients and it is better than that of composting process. Present review deals with the various aspects of vermicomposting of POMW and its importance. Review also put forward the effect of potential application of vermicompost on plant growth. On the whole it looks for the possibility of vermicomposting of waste from palm oil mill as a sustainable waste management alternative. 相似文献

基于区间层次分析法的石油库防火防爆安全评价 总被引:2,自引:1,他引:1
为准确反应石油库防火防爆安全状态,给石油库安全管理工作提供科学依据,应用区间层次分析法(IAHP)对石油库进行防火防爆安全评价。通过分析石油库防火防爆安全影响因素,构建3级安全评价层次结构体系。针对专家构造判断矩阵时决策的不确定性,采用区间数来描述因素之间的两两比较,应用区间特征根法(IEM)求出12项评判指标的区间权重向量及权重总排序。研究表明:影响石油库防火防爆安全状态最大的4个因素依次为:消防灭火设备状态、技术设备状态、防静电设备状态和工艺设备状态。评价结果与石油库的实际安全状况相符。 相似文献

流沙湾海水中石油烃的时空分布特征研究 总被引:1,自引:0,他引:1
于2008年2月(冬季)、5月(春季)、8月(夏季)和11月(秋季)对流沙湾进行了4次采样考察,研究分析了流沙湾表层海水中石油烃质量浓度的平面分布和季节变化特征。结果表明,在2008年度,流沙湾表层海水石油烃的质量浓度为0~1.930 mg.L-1,平均值为0.080 mg.L-1,季节差异比较明显,呈春、冬、夏、秋季依次减小的变化趋势,冬、春季节海水呈现不同程度石油污染,夏、秋季节属Ⅰ、Ⅱ级水质,整个流沙湾海域表层海水石油烃的平面分布相对比较均匀。在内外湾分布上,冬、春、秋季节外湾大于内湾,而夏季节内湾大于外湾。流沙湾的水产养殖活动是其海水石油烃时空分布的主要影响因素。 相似文献
