煤矿区表层土壤中芳香烃组成、分布特征及标志化合物研究

采用GC-MS技术分析了平顶山市石龙区土壤样品中多环芳烃(PAHs)污染物的化学组成及分布特征,共鉴定出78种代表性化合物,包括11种US EPA优控PAHs.结果表明,总体上土壤样品中单体烃菲、荧蒽、芴、芘含量比较高.在不同功能区域芳烃含量差别较大,采矿区及焦化厂区土壤中芳烃含量明显高于污灌区和农业区,而煤矸石山附近土壤中芳烃含量最高.采矿区、焦化厂区和污灌区土壤中低环数PAHs的比例远大于高环数PAHs,农业区反之.通过对(ρ)MP/(ρ)P、MPI1、(ρ)P/(ρ)A、(ρ)FL/(ρ)PY等参数值的分析认为,煤尘、烟灰沉降是石龙区土壤中PAHs积累的主要影响因素.由单体烃与PAHs的相关性分析得知,苊和蒽可作为煤矿区域表层土壤中PAHs的标志性污染物.

新疆宝浪油田污水达标回注技术应用

新疆宝浪油田污水处理原来采用外排方式,严重污染了周边环境。为此,通过对处理工艺进行的改进,对分散自控系统的升级改造及对处理药剂进行了重新筛选。改造后终端出口水质的悬浮物由200 mg/L下降到3.93 mg/L,去除率为96%,含油量由200 mg/L降为0.79 mg/L,去除率为99%,含铁为3.9 mg/L,细菌总数为4.5个/mL,硫酸盐还原菌为4.5个/mL,处理后的污水水质达到了《碎屑岩油藏注水水质推荐指标及分析方法》标准回注要求。     

秦皇岛近海养殖区域夜光藻种群动态与环境温度的关系

本文通过对秦皇岛近海养殖区夜光藻的调查,分析研究了夜光藻种群的动态与温度变化的关系。结论:夜光藻在秦皇岛近海养殖区内出现在3月份,并在7月份出现密度高峰,9—10月份偶有出现,11—2月份则未出现。夜光藻最高密度出现的温度为25—26℃,夜光藻在秦皇岛近海的出现及7月份的密度高峰与水温的变化密切相关。

Risk attitudes and mitigation among gold miners and others in the Suriname rainforest

This article analyses the question: do attitudes towards risk influence participation in small‐scale gold mining, a hazardous activity that generates uncertain income? This question is examined by measuring and comparing the risk attitudes of gold miners and non‐mining community members in the rainforest of Suriname, South America. The author presents a multivariate model to predict the duration of work in mining areas as a function of risk tolerance, age, education, and household demographics. The results suggest that a greater tolerance to risk increases the duration of a person's mining career. However, attitudes explain only a fraction of the variation in occupational choices. Qualitative data suggest that these choices are primarily shaped by local barriers to human capital development and by national economic volatility. Given their marginal position in society and the multitude of mining risk mitigation strategies, it is questionable whether gold mining exposes Suriname forest peoples to greater risks than other subsistence alternatives. The author argues that sensitivity to local historical and cultural conditions would improve the efficiency of policies aimed at developing a more sustainable mining industry. By zooming in on the daily lives of miners, anthropology can complement macro‐scale analyses and contribute to policy interventions in the small‐scale mining sector.     

Strategies for sustainable development of the small-scale gold and diamond mining industry of Ghana

The small-scale gold and diamonds mining industry is of great importance to Ghana. Since its regularization in 1989 the sector has produced and sold over 1.5 million troy ounces of gold and 8.0 million carats of diamonds. During the same period the sector also provided direct employment to over 100,000 people and improved the socioeconomic life of many individuals and communities. However, these were largely achieved at a cost to the environment in areas where mining is carried out and there is the need to develop the industry in a sustainable manner. This paper looks at the developments in the small-scale gold and diamonds mining industry in Ghana and proposes some strategies on how the concepts of sustainable development could be applied to the industry.
