Colorado's Cinnamon Gulch releases acid rock drainage (ARD) from anthropogenic and natural sources. In 2001, the total discharge from Cinnamon Gulch was measured at 1.02 cfs (29 L/s) at base flow and 4.3 cfs (122 L/s) at high flow (spring runoff). At base flow, natural sources account for 98% of the discharge from the watershed, and about 96% of the chemical loading. At high flow, natural sources contribute 96% of discharge and 92 to 95% of chemical loading. The pH is acidic throughout the Cinnamon Gulch watershed, ranging from 2.9 to 5.4. At baseflow, nearly all of the trace metals analyzed in the 18 samples exceeded state hardness-dependent water quality standards for aquatic life. Maximum dissolved concentrations of selected constituents included 16 mg/L aluminum, 15 mg/L manganese, 40 mg/L iron, 2 mg/L copper, 560 g/L lead, 8.4 mg/L zinc, and 300 mg/L sulfate. Average dissolved concentrations of selected metals at baseflow were 5.5 mg/L aluminum, 5.5 mg/L manganese, 14 g/L cadmium, 260 g/L copper, 82 g/L lead, and 2.8 mg/L zinc. 相似文献

This study assessed the ability of filamentous green algae; Spirogyra aequinoctialis to accumulate manganese, cadmium and lead from water. Water pH was also determined. Samples of S. aequinoctialis and their respective water environments were taken from designated sampling points in the city of Blantyre and Malawi during the rainy and dry season in order to capture seasonal variations. The concentration of metals in S. aequinoctialis were higher than in the corresponding water environment in both seasons, but lower in the rainy season than the dry season. In the rainy season the concentrations were (in S. aequinoctialis and (water)): Mn 0.432–5.641 mg/L (ND-0.530 mg/L), CdND- 0.016 mg/L (0.07–0.111 mg/L) andPbND- 0.965 mg/L (0.011–0.098 mg/L). In the dry season the concentrations were: Mn 0.281-16.132 mg/L (0.035–0.626 mg/L), Cd 0.22–0.912 mg/L (0.014–0.111 mg/L) and Pb ND- 0.972 mg/L (ND- 0.23 mg/L). This study has shown that S. aequinoctialis has the capability of accumulating manganese, cadmium and lead. Therefore it can be used as a biological indicator for long term heavy metal water pollution monitoring. 相似文献

贵州省饮用天然矿泉水资源非常丰富,且水质优良,本文对贵州省岩溶地区饮用天然矿泉水进行了系统的水样采集、水质化验等工作。检测结果显示,贵州省岩溶区饮用天然矿泉水pH值7. 0～8. 1,为中性水;溶解性总固体(TDS)含量介于160. 64～925. 10 mg/L之间,平均含量为369. 70 mg/L,属淡水;总硬度(以CaCO_3计) 136. 8～740. 6 mg/L,平均硬度为293. 0 mg/L,属微硬-硬水;有益元素锶含量介于0. 11～6. 91 mg/L之间,平均含量为1. 28 mg/L,总体上,贵州省饮用天然矿泉水属中性微硬-硬富锶型淡水。Piper三线图显示其水化学类型以HCO~(3-)-Ca~(2+)(Mg~(2+))为主。基于前人研究成果,并结合多种地球化学图解分析,旨在剖析贵州省饮用天然矿泉水水化学特征,探讨其宏量组分来源。贵州省饮用天然矿泉水Gibbs图解显示,其水化学组分主要来源于岩石风化淋滤作用,部分受大气降雨影响较明显; Mg/Na-Ca/Na图解投点均落于碳酸盐岩和硅酸盐岩之间,且明显偏向于碳酸盐岩,指示其主要受控于碳酸盐岩的溶滤作用;HCO~(3-)-(Mg~(2+)/Ca~(2+))图解投点主要集中在方解石和白云石过渡区域,显示其主要来源于方解石的溶解,白云石溶解亦有一定贡献。通过宏量组分来源相关分析,对贵州省岩溶地区饮用天然矿泉水成因规律的认识有一定指导意义。 相似文献

Deterioration of groundwater quality in the vicinity of an active open-tipping site in West Malaysia 总被引：3，自引：0，他引：3

There is an urgent need for characterization of leachate arising from waste disposal to ensure a corresponding effective leachate management policy. Field and laboratory studies have been carried out to investigate the impact of municipal landfill leachate on the underlying groundwater at a site in West Malaysia. The solid waste was disposed of directly onto an unprotected natural soil formation. This situation was made worse by the shallow water table. The hydrochemical composition of groundwater in the vicinity of the site (background) is a dilute mixed cation, bicarbonate water. The high ionic balance error of ~13.5% reveals that the groundwater body underneath the site was a highly contaminated leachate rather than contaminated groundwater. Elevated concentration of chloride (355.48 mg/L), nitrate (10.40 mg/L as NO3), nitrite (14.59 mg/L), ammoniacal-N (11.61 mg/L), sodium (227.56 mg/L), iron (0.97 mg/L), and lead (0.32 mg/L) measured downgradient indicate that the contamination plume has migrated further away from the site. In most cases, the concentration of these contamination indicators, together with the ranges of sodium percentage (66.3–89.9%) and sodium adsorption ratio (10.1–19.7%), were found to be considerably higher than the limit values of safe water for both domestic and irrigation purposes, respectively. 相似文献

Anomalous concentrations of numerous major and minor elements significantly exceeding the threshold limit values (TLV) for drinking water were registered in the area of the Tyrnyauz Tungsten–Molybdenum Combine (TTMC). The maximal excess of the TLV (by one or two orders of magnitude) were obtained for Mo (up to 11 mg/L), W (4.4 mg/L), As (1.5 mg/L), Mn (8.4 mg/L), and Tl (up to 3.3 μg/L) in water of the Bolshoi Mukulan Brook flowing through the mines and three brooks flowing out from the base of the embankment of the tailing store no. 1. They are the major pollutants for water of the Baksan River. Upon flowing out to the plain, water of the Baksan River shows significant excess of the TLVs (in summer) for Al, Fe, Mn, Be, Si, Ti, Tl, and Hg. 相似文献
