The metal concentrations in a copper mine tailings and desert broom (Baccharis sarothroides Gray) plants were investigated. The metal concentrations in plants, soil cover, and tailings were determined using ICP-OES. The concentration of copper, lead, molybdenum, chromium, zinc, arsenic, nickel, and cobalt in tailings was 526.4, 207.4, 89.1, 84.5, 51.7, 49.6, 39.7, and 35.6mgkg(-1), respectively. The concentration of all elements in soil cover was 10-15% higher than that of the tailings, except for molybdenum. The concentration of copper, lead, molybdenum, chromium, zinc, arsenic, nickel, and cobalt in roots was 818.3, 151.9, 73.9, 57.1, 40.1, 44.6, 96.8, and 26.7mgkg(-1) and 1214.1, 107.3, 105.8, 105.5, 55.2, 36.9, 30.9, and 10.9mgkg(-1) for shoots, respectively. Considering the translocation factor, enrichment coefficient, and the accumulation factor, desert broom could be a potential hyperaccumulator of Cu, Pb, Cr, Zn, As, and Ni. 相似文献

A guideline is drafted describing the screening procedure in detail. The aim for this is to facilitate an adoption of this test by bodies supervising environmental chemicals. Successful introduction of this method into the respective laboratories will cause no problems, as the procedure has been collaboratively established and improved. 相似文献

Efficient recycling of solid wastes is now a global concern for a sustainable and environmentally sound management. In this study, traditional recycling pattern of solid waste was investigated in Rajshahi municipality which is the fourth largest city of Bangladesh. A questionnaire survey had been carried out in various recycle shops during April 2010 to January 2011. There were 140 recycle shops and most of them were located in the vicinity of Stadium market in Rajshahi. About 1906 people were found to be involved in recycling activities of the city. The major fraction of recycled wastes were sent to capital city Dhaka for further manufacture of different new products. Only a small amount of wastes, specially plastics, were processed in local recycle factories to produce small washing pots and bottle caps. Everyday, an estimated 28.13 tons of recycled solid wastes were handled in Rajshahi city area. This recycled portion accounted for 8.25% of the daily total generated wastes (341 ton d?1), 54.6% of total recyclable wastes (51.49 ton d?1) and 68.29% of readily recyclable wastes (41.19 ton d?1). Major recycled materials were found to be iron, glass, plastic, and papers. Only five factories were involved in preliminary processing of recyclable wastes. Collecting and processing secondary materials, manufacturing recycled-content products, and then buying recycled products created a circle or loop that ensured the overall success of recycling and generated a host of financial, environmental, and social returns. 相似文献

This study presents the determinants and development strategies of agricultural systems of the Hill Tracts of Chittagong in Bangladesh using multivariate analysis. A total of 18 selected variables transformed into 4 factors extracted by principal factor method explain 77.21 % of the total variability of the agricultural systems in Chittagong Hill Tracts (CHT), and the agricultural systems in CHT are classified as extensive, semi-intensive, intensive and mixed using cluster analysis. Agricultural extension services, credit facilities and infrastructure such as distance to markets are identified as the main factors responsible for the changes in agricultural systems in CHT. Finally, it has been suggested to provide knowledge and skills to the farmers in CHT through agricultural extension using farmer field schools, microcredit using Grameen Bank approach and facilities such as improved transportation to the markets for better price and higher profit from the sale of the agricultural products to enable the farmers to move from shifting cultivation to environmentally and economically sound semi-intensive or intensive agricultural systems. 相似文献
