The Impact

This study aims to investigate the quality and vulnerability of surface water (Aries River catchment) in order to identify the impact of past mining activities. For this purpose, the pollution and water quality indices, Piper and Durov plots, as well vulnerability modeling maps were used. The obtained results indicate that the water samples were contaminated with As, Fe, Mn, Pb and have relatively high concentrations of SO42−, HCO3−, TDS, Ca, K, Mg and high values for the electrical conductivity. Possible sources of the high content of chemicals could be the natural processes or the inputs of the mine drainage. Generally, according to the pollution indices, which were correlated to high concentrations of heavy metals, especially with Pb, Fe and Mn, the water samples were characterized by heavy metals pollution. The water quality index classified the studied water samples into five different classes of quality, namely: unsuitable for drinking, poor, medium, good and excellent quality. Similarly, medium, high and very high vulnerability classes were observed. The Durov and Piper plots classified the waters into Mg-HCO3− and Ca-Cl− types. The past and present mining activities clearly change the water chemistry and alter the quality of the Aries River, with the water requiring specific treatments before use.

Zoosporic Fungi

Thirty-four identified in addition to five unidentified species appertaining to ten genera of zoosporic fungi were identified and isolated from eighty four polluted water samples, which were randomly collected from different polluted sites of the water drainages along the Niles Delta in Lower Egypt. Baiting sesame seeds culture technique was employed at 20±2º C for the recovery of zoosporic fungi. The genera; <em>Pythium</em> and <em>Saprolegnia</em> (8 and 7 zoosporic fungal species, respectively) showed the broadest spectra of species diversity whereas <em>Aqualinderella</em> was only represented by one species (<em>A. fermentans</em>). <em>Saprolegnia delica</em> and <em>Dictyuchus carpophorus</em> (the greatest fungal populations) were the most dominant isolated zoosporic fungal species where they were highly occurred especially at the hyper-polluted waters with the heavy metals. These two species could be considered as indicators for the response of the structure and function of microbial communities for water pollution. Several zoosporic fungal species were rarely encountered. Both <em>Aqualinderella fermentans</em> and <em>Pythium rostratum</em> were recovered in moderate frequency of occurrence. Water samples which had high concentrations in heavy metals were the poorest in the species diversity of zoosporic fungi. Despite that, fungal species belonging to the family <em>Saprolegniaceae</em> flourished in hyper polluted water samples whilst those belonging to the family <em>Pythiaceae</em> predominated in more diluted water samples. Also, the prevalent species; <em>S. delica</em> and <em>D. carpophorus</em> were not affected by heavy metals concentrations being as indicators for water pollution with the heavy metals. pH values of the polluted water samples had no influence on the occurrence of zoosporic fungi. Water samples characterized by high organic matter content and low total soluble salts were the richest in zoosporic fungal species.

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.

The measurements of major and trace elements in different brands of milk powder selected from the Iraqis market via the X-ray fluorescence (XRF) Technique have been studied in the present work. The result of the measurements reveals the high concentrations of sodium, phosphorus, sulfur, chlorine, potassium, calcium and magnesium. Furthermore, low concentrations of aluminum, silicon, iron, bromine, molybdenum, iodine, barium, titanium, manganese, cobalt, chrome, nickel, copper, zinc and lead were detected. Neutron activation analysis (NAA) and Kjeldahl technique were also employed to determine the concentrations of nitrogen. It was found that the nitrogen concentration was in the range of (1.96 - 3.23) % which is within the permissible limits. The concentrations of the trace elements (copper, manganese, zinc, lead) were verified via the atomic absorption spectrometer (AAS) technique. The results are compared with the authorized limit by the food and agriculture organization and the world health organization (FAO/WHO) standards.

El presente estudio busca determinar la presencia de metales pesados, Cadmio y Plomo, en el estuario del Río Chone, Ecuador, durante Junio a Septiembre de 2014; se obtuvieron seis muestras de agua y cinco de suelo en seis sitios, con dos réplicas por sitios, dando el total de 66 muestras. El análisis se realizó según el protocolo del Kit para Cadmio y Plomo de Merck-Millipore. En el agua las concentraciones de Cadmio fueron mayores en el sitio P4 (0,129 mg/L). En el sedimento, el nivel de Cadmio en el sitio P2 presentó mayor acumulación (0,0033 mg/g), para Plomo, los sitios con mayor nivel fueron P5 y P6 (0,18 – 0,21 mg/L respectivamente), lugares con mayor flujo de agua del estuario del Río Chone (8 UPS: Unidades Prácticas de Salinidad) y menor influencia con las corrientes del agua del Mar (30 UPS). Los resultados comparados con la legislación Ecuatoriana evidencian concentraciones  altas de Cadmio en el ecosistema del estuario en estudio, que podría afectar la salud de organismos que viven a nivel de la columna de agua, tales como peces, al igual que actividades de recreación de los bañistas locales, de los cantones Sucre y San Vicente Manabí.ABSTRACTThe present study aims to determine the presence of cadmium and lead heavy metals in the Chone River estuary; Ecuador, during June to September 2014, six water samples and five soil samples were obtained at six sites, with two replications per site giving a total of 66 samples. The analysis was performed according to the protocol of Merck-Millipore Kit for cadmium and lead. Cadmium concentrations in the water were higher at the P4 site (0.129 mg/L). The level of cadmium in the sediment showed greater accumulation (0.0033 mg/g) in the P2 site. The sites with higher level of lead were P5 and P6 (0.18 y 0.21 mg/L respectively), these were places with greater flow of water of the Chone River estuary (8 UPS: Practical Units of Salinity) and less influence of the sea water currents (30 UPS).The results compared with Ecuadorian legislation show high concentrations of cadmium in the ecosystem of Chone River estuary, which could affect the health of organisms living at the water column level, such as fish, as well as recreational activities for local bathers from Sucre and San Vicente cantons from Manabí province.

Riverbank filtration (RBF) provides an alternative to extract raw water by removing pollutants such as suspended solids, organic carbon, and pathogenic bacteria/microbes in the water. However, the main issue with this system is the occurrence of high concentrations of arsenic (As), iron (Fe), and manganese (Mn) in the production well. Therefore, this study was conducted to compare the presence of heavy metals in river water and pumping well water for an RBF system. Water samples were collected from Sungai Kerian (Kerian River) and a pumping well during a three-day pumping test. The heavy metal concentration in both samples was analyzed for 21 elements using ICP-OES. A total of 12 elements were detected in the water samples from either the river or the pumping well. Among the detected elements, As and Fe had concentrations that exceeded the standard values set by the Ministry of Health, Malaysia. Results also suggested that the Fe concentration in the pumping well water was higher than that in the river water. Conversely, As was more frequently detected in the river water than in the pumping well water. These results imply that the As concentration in the river water was derived from external sources, while the presence of As and Fe in the pumping well water was influenced by geochemical and hydrochemical processes in the aquifer.

A pot experiment was conducted to investigate the effect of irrigation water collected from different industrial areas on Red amaranth (Amaranthus tricolor L.) and tomato (Solanum lycopersicum L.). Collected water samples were analyzed for various parameters, which include pH, DO, BOD, COD, P, NH3-N, K, S, Zn, Cu, Pb and Cd. The results were compared with the irrigation water quality standards by the Department of Environment (DoE) of Bangladesh and many of them were found several-folds higher than the permissible limit. The deterioration trends of the water samples are as follows: Tejgaon canal > Rampura canal > Sitalakhya river. Dry matter of vegetables grown on Tejgaon soil was significantly (p ? 0.05) higher than that of agricultural soil. Both red amaranth and tomato grown in Tejgaon soil accumulate highest concentration of heavy metals followed by Rampura and Sitalakhya soil. The concentrations of zinc (Zn), lead (Pb) and cadmium (Cd) in edible portions of both vegetables were found several times higher than the WHO prescribed permissible limits. The concentration of heavy metals in vegetables were found in the order Zn > Cu > Pb > Cd.Bangladesh J. Sci. Res. 28(2): 151-159, Dec-2015

ABSTRACT Concentrations of the heavy metals arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), iron (Fe), mercury (Hg), lead (Pb), and zine (Zn) were measured in muscle, liver, and gonads of walleye pollock (Gadus chalcogrammus) caught in waters off the northeastern coast of Korea. Zn concentration was the highest in the three tissues, and all heavy metals, except Hg, were selectively accumulated in liver relative to muscle and gonads. The metal concentrations in muscle and gonads, except Cd and Zn in some gonad samples, were below the national and international regulatory limits set by various countries and by the Food and Agriculture Organization of the United Nations. The estimated daily intakes of heavy metals were in the range of 0.003 to 1.341% of the provisional maximum tolerable daily intakes, and the hazard quotients of the heavy metals were less than 1.0. Our results suggest that the intake of heavy metals by the consumption of G. chalcogrammus does not have significant adverse effects on health. HIGHLIGHTS
