Heavy metals belong to a group of substances, which, after reaching a natural habitat, can manifest various negative effects. This paper analyses heavy metals (Cu, Cd, and Pb) in the Una river and fish samples, whereby individuals of grayling (Thymallus thymallus) were used for analysis. The samples were taken at three locations at the Una river: Ripač, Hatinac, and Grmuša. Alongside with the examination of the content of heavy metals, quality of water was tracked, including the following parameters: temperature, pH, electrical conductivity, dissolved oxygen, suspended matter, BPK5, KPK – Cr, total nitrogen – N, total phosphorus P, sulphates, chlorides, nitrites – NO2, nitrates – NO3, fluoride, and heavy metals (Cu, Cd, and Pb). Besides the content of heavy metals, proteins, fats, water, carbohydrates, and mineral matter were found in the grayling fillets. Amount of heavy metals (Pb, Cu, and Cd) were under maximum allowed concentration (MAC).

Water is essential part of ecosystem, so its quality must be ascertained for use especially in Ekole creek of Nigeria where dredging activities is heavy, hence this study examined the dredging effect on the downstream water quality of Ekole creek. Water samples were collected from four points which are; Upstream, Dredge I, Dredge II, and Downstream points. The parameters of the water quality determined showed that Turbidity and Total Suspended Solids (TSS) were higher at the Downstream point with values of 31 NTU and 1664 mg/l respectively; pH was also slightly acidic (6.61); but low in Total Dissolve Solid (TDS), Electrical Conductivity,  Nitrate (NO3) and Dissolved Oxygen (DO), as compare to the Upstream. The values of the  heavy metals like Pb (3.845 mg/l), Cr (0.612 mg/l) Ni (0.104 mg/l) and Cu (0.128 mg/l),  at Downstream point, were above Pb (3.0605 mg/l), Cr (0.0 mg/l), Ni (0.017 mg/l) and Cu (0.102 mg/l) of  the Upstream point,before the Dredging points I and II, that have  correlative matrix of(Pb>Fe>Mn>Zn>Cu>Ni>Cr) and  Pb>Fe>Cr>Mn>Zn>Cu>Ni Downstream point. Is discovered the Downstream water is slightly acidic, high in Turbidity and TSS, but low in TDS, EC, NO3 and DO, as against the WHO drinking-water quality, due the effect of dredging on the water quality of the Ekole Creek. It is inferred that the dredging activities have negative effects on the water quality, which can be hazardous to the health of downstream user, and distort the ecosystem; therefore the commercial dredging activities should be checked in Ekole creek.

Climate change has an important impact on the environment. As it degrades the quality of water, soil, and area, it also spreads the distribution of many toxic elements, specifically heavy metals and pesticides. The impact of climate change on contamination with heavy metals and pesticides has been well investigated and discussed. The influence of these elements on human health is obviously exacerbated following their extended distribution. Moreover, a wide range of health problems have been associated to such intoxication, among which impairment and dysfunction of the nervous system are prominent. In this chapter, the authors will shed light on two most common neurological diseases such as epilepsy and stroke affecting people worldwide arising from food and water contaminations, mainly with heavy metals and pesticides.

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, overcome geochemical barriers in the soil and enabled heavy metals to migrate from the soil to the groundwater and from river bottom sediments to the surface water.

The paper presents the results of the determination of heavy metals in drinking water samples from centralized water supply systems and wells of individual water supply of the Sverdlovsk region. It was found that the content of copper ions in the samples does not exceed its maximum permissible concentration, and the content of lead and cadmium ions in most samples is higher than the permissible norms. It is established that water samples from Nizhny Tagil and Serov are more contaminated with cadmium. The causes of drinking water pollution are discussed. It was found that the pollution of water from the centralized water supply systems with heavy metals is mainly due to the non-compliance of the operated water pipes with sanitary and hygienic requirements. Groundwater pollution is caused by the infiltration of industrial effluents containing heavy metals from storage and sedimentation tanks through soil. It is shown that numerous industrial enterprises in the Sverdlovsk region aggravate the process of pollution of surface and groundwater with heavy metals. The unsatisfactory quality of water in terms of the content of heavy metals in Sverdlovsk region is revealed. The authors dwell on the need to continue research to determine the content of other heavy metals in water and expand the geography of sampling in the region in order to assess more accurately the quality of water.

Impervious Areas

The increasing urbanization process in Europe has resulted in an increase in the proportion of impervious areas in the development of watersheds. This fact, combined with the more frequent occurrence of volatile rainfall, contributes to the formation of high intensity surface runoff, which results in local flooding of the lowest located areas. Water runoff also causes a large amount of pollution from the catchment to be flushed away and transported to the receiver, which generates many negative effects on the environment. Due to these unfavorable changes in the urban catchment, it is necessary to manage the waters in accordance with the principles of sustainable development. One of the basic tools to protect the quantity and quality of water discharged from the catchment area is to take into account the need to implement technical solutions to increase the retention of rainwater in cities. Such solutions, consisting of designing natural rainwater management systems, could work independently or in cooperation with traditional rainwater drainage systems [1].

The present work seeks to evaluate the safety and quality of water for injection (WFI) marketed in south-Eastern Nigeria. The physical, microbiological and chemical qualities of different brands of WFI marketed in south- eastern Nigeria were evaluated in order to ascertain their quality. A total of one hundred and forty-seven (147) samples of four different brands of WFI (approximately thirty vials per state) were analysed. All the brands (A, B, and C) except D conformed to the PH range (5.0-7.0) at room temperature. The PH value of all the brands reduced when subjected to increased temperature. All the brands were also sterile. All the brands passed the conductivity test with respect to compendia standard. The study revealed that the various brands of WFI marketed in south-eastern Nigeria conform to some official limits except for heavy metals. However, WFI in south-eastern Nigeria are considerably safe.

Summary By using biological assay in the laboratory were tested quality and impact of the water to the selected test plants: buckwheat (Fagopyrum esculentum) and cabbage (Brassica oleracea). Water was analyzed from two locations from the River Douro in Portugal. Physico-chemical analysis of general parameters in the water samples indicate that electrical conductivity and ammonium were detected in values exceeding MAC, according to Portuguese regulations on water quality. Also, in the analyzed samples of water in quantities that exceed the maximum allowable concentration values are: arsenic (As), selenium (Se), iron (Fe), magnesium (Mg). In tested samples several pharmaceuticals were detected. The obtained results indicate differences in tolerance of the test plants towards the quality of water. Physiological parameters (germination energy and germination) are not good indicators of water quality and more reliable can be considered some morphological traits (length, fresh and dry weight of root and shoot), that reacted in inhibition or stimulation, depending on water quality.

Freshwater or wetlands are being polluted on regular basis due to the release of domestic sewage and most importantly industrial effluents that include chemicals, organic pollutants and heavy metals, and run-off from land-based activities containing leached fertilizers. Pollutants are such substances that reduce quality of water that effect directly and indirectly. The present study was carried out on Korang River Islamabad/Rawalpindi. Two different locations were selected along the Korang River. The data were collected two times during the current study period; March 2012, and October 2012. Ranid frogs (n=10) were captured from all selected sites, which were dissected to collect blood and body tissue samples. During the month of March and October the concentration of heavy metals in water samples increase and decrease significantly at both sites of Korang River. The continuous leaching of contaminants may cause abnormal tissue damage in amphibians making them more vulnerable to predation and competition and also decreased reproductive success.
