Abstract:

Heavy metal pollution in groundwater has become a widespread issue worldwide. However, information on heavy metal pollution in groundwater of inland river basins in NW China remains limited. This study evaluated pollution and ecological health risks of heavy metals in groundwater of the Zhangye Basin, which is a typical inland river basin in NW China. The concentrations of heavy metals in groundwater were relatively low. Heavy metals in groundwater of the northeastern edge and western regions of the study area showed a higher concentration than those of the remaining parts. Iron was the domina

Abstract:

Groundwater is a major source of drinking and agricultural water supply in arid and semiarid regions. Poor groundwater quality can be a threat to human health especially when it is combined with hazardous pollutants like heavy metals. In this study, an innovative method involving entropy weighted groundwater quality index for both physicochemical and heavy metal content was used for a semiarid region. The entropy weighted index was used to assess the groundwater’s suitability for drinking and irrigation purposes. Thus, groundwater from 19 sampling sites was used for analyses of physicochemical

In conditions of increasing anthropogenic pressure on the objects of the natural environment, an objective assessment of the hydrochemical state of water bodies is necessary, taking into account background values of heavy metals, the presence of which is associated only with natural factors. Therefore, the aim of our studies was to determine the concentration of heavy metals in groundwater lying in different geological and geomorphological conditions in a territory remote from the large industrial centers – Dnipro and Pavlograd.

Abstract:

Ground waters may undergo a process of contamination in various ways, but the presence and amount of heavy metals in them can be indicative of their purity and usage. Apart from that, the heavy metals are among the most widely spread pollutants in nature, and their presence in groundwater indicates the existence of natural or anthropogenic sources of contamination. Ground waters polluted with heavy metals can also be very toxic and harmful to human health, and very damaging to the environment as well. In this article, the concentrations of eight toxic heavy metals (Fe, Mn, Cu, Al, Ni, Pb, Zn,

Abstract:

The principal impediment in the remediation of contaminated sites and in the protection of groundwater quality is the lack of appropriate and reasonable standards for heavy metals in soils. There are no standards applicable to predict the potential for groundwater contamination by heavy metals in Taiwan. Lack of these soil standards may result in subjective judgment regarding the remediation needed. The migration of heavy metals through the unsaturated zone to groundwater is controlled by sorption to the soil, a highly pH-dependent process, and the hydrological regime. Soil sorption behavior i

Land treatment of waste biological solids (sludge) has been practiced many years and there have been many studies conducted to determine the applicability of this disposal technique. This paper is based upon an investigation which was conducted to determine if the heavy metals which are associated with sludge are stabilized and contained within a landspread area where no agricultural crops are grown. Sludge/soil mixture samples were analyzed for heavy metal concentrations and cation exchange capacity (CEC) on a routine basis to determine if the heavy metals were remaining in an insoluble form.

In order to evaluate the groundwater quality in the Xihe River Basin, the concentrations of fluoride (F-), chloride (Cl-), nitrite (NO2-), nitrate (NO3-), mercury (Hg), cadmium (Cd), zinc (Zn), lead (Pb) and barium (Ba) of the groundwater were investigated in the three sections, Section I, II and III for the upstream, midstream and down stream, respectively. A method of Nemero composite index was used to evaluate the groundwater quality. The concentrations of nutrient salts of groundwater in the Xihe River basin decreased from the upstream to the midstream and downstream. The values of heavy m

Abstract. In August and September 2002, concentrations of heavy metals (copper, lead, and zinc) were 21-74% more than in previous years in Lithuanian rivers. Such a sudden increase in heavy metal pollution reduces the value of any water body for fishing or recreation and poses a potential risk to the environment and to human health. Droughts in the summer of 2002 led to forest and peat bog fires all over Lithuania and may have caused the increase in concentrations of heavy metals detected in Lithuanian rivers in August 2002. The fires could have changed the pH in the top layers of the soil, ov

Arsenic contamination in groundwater is a common groundwater problem worldwide. To manage groundwater resources effectively, it is crucial to determine the arsenic source. Taiwan&rsquo;s Tsengwen Creek watershed is one of the known areas for groundwater arsenic contamination. Water-rock interactions are evaluated on a regional scale. A conceptual hydrogeological framework is first established based on groundwater hydrochemistry. The local aquifer system can be categorized into high-arsenic deep aquifer and low-arsenic shallow aquifer. The average geochemistry of sediments indicates that ar

The spatial distribution of naturally occurring heavy metals is highly heterogeneous and significantly increased concentrations may be present in the soil at certain locations.

Arsenic is present in water samples within the studied active floodplain areas of the Tista river, Rangpur Division, Bangladesh. All the water samples contain less arsenic than the WHO prescribed limit of 10 μg/L. 93.33% groundwater samples have higher Mn content than the permissible limit of 0.01 mg/L of WHO. The heavy metal concentrations of water can be expressed as Fe>Mn>Zn>As on the basis of their mean content. The heavy metals are negatively correlated with the well depth which is indicative of the influence of the anthropogenic activities on the concentrations of heavy metals.

The uncontrolled release of acid mine drainage (AMD) from abandoned mines and tailing piles threatens water resources in many sites worldwide. AMD introduces elevated concentrations of sulfate ions and dissolved heavy metals as well as high acidity levels to groundwater and receiving surface water. Anaerobic biological processes relying on the activity of sulfate reducing bacteria are being considered for the treatment of AMD and other heavy metal containing effluents. Biogenic sulfides form insoluble complexes with heavy metals resulting in their precipitation. The objective of this study was
