The Musi River is one of the biggest river of twelve big rivers in South Sumatra Province. Water quality of this river affects the water quality in the estuary and biological health in its surrounding so that it is important to determine the Cu and Pb concentrations. The purposes of this study were to analize distribution of heavy metals (Cu and Pb) and to determine the water quality status in March and September 2014. The water and sediment samples were collected from eight stations along the Musi River from downstream to the estuary. Heavy metal concentration was analized by employing USEPA 30050B method using AAS Spektra plus variant with air mixure flame – acetylene. Dissolved Cu and Pb concentrations in March were 0,002 - 0,006 mg/l and 0,002-0,003 mg/l, respectively, while in September were 0,001-0,010 mg/lfor Cu and 0,001-0,005 mg/lfor Pb. Cu and Pb concentrations in sediment detected in March were 6,92-16,4 mg/l and 1,9-11,4 mg/l, respectively, while in September were  2,3-13,9 mg/l for Cu and 4,29-9,95 mg/l for Pb. Student test analysis showed that was no significant differences between Pb and Cu concentrations (dissolved and sediment) between March and September. Generally, the concentration of heavy metals Cu and Pb in Musi River estuary were still below specified quality standards.Keywords: heavy metal, Cu, Pb, the Musi River, estuary

The seasonal investigation about the water quality from Damanganga river estuary on two habitats downstream and upstream was carried out from January to December 2019 containing three major seasons: winter, summer and monsoon. For this monitoring activity total 29 parameters (24 physico-chemical parameters and 5 heavy metals) were analyzed. Multivariate analyses suggested inter dependency among these studied parameters. Water Quality Index is computed based on the major fluctuated and affected parameters. The calculated values of WQI for all three seasons ranged from 122.84 to 173.82 which suggested poor water quality of the water body. WQI values of the investigation area proposed that the estuarine water quality is deteriorated due to high value of presented heavy metals (Aluminum, Iron, Manganese, Boron and Zinc), Chloride, Ammonium and Sulfate in water sample. In this case, the downstream station is having accessional pollutant contaminations while the upstream station is having diminutive pollutant contaminants.

Mosaic sludge is sewerage from mosaic industrial activities such as cutting, polishing and grinding. This sludge mostly will be disposed directly to landfill and some of it was discharged in drainage system without proper treatment. Therefore, in this study, mosaic sludge from the mosaic industry were reused and incorporated into fired clay brick in order to provide alternative disposal method, producing adequate quality of brick as well as minimizing the heavy metal leachability to the environment. First, X-Ray Fluorescence (XRF) was conducted to determine the heavy metal concentration from two types of mosaic sludge. The results indicate that the highest element concentration in mosaic sludge (BS and PS) shows that Barium is the highest with 3253ppm and 3260ppm. On the raw sludge, the lowest obtained in BS and PS is Cesium with 14ppm and 17ppm. SPLP and TCLP also conducted in this study and the results show that, even though the element such as ferum (Fe) and cadmium (Cd) was not detected in XRF but in SPLP and TCLP, it shows that these two elements exist in clay, BS and PS with low concentration. In term of properties, compressive strength was conducted by incorporating 0%, 1%, 5%, 10%, 20% and 30% bodymill and polishing sludge into fired clay brick. The results show that compressive strength of BS brick was stronger than PS brick. Lastly, Static Leachate Test (SLT) was conducted to measure the long term leachability of heavy metals from different percentages of mosaic sludge brick. In SLT result, ferum (Fe) shows the highest value of heavy metal concentration among other elements. The results for control brick, BS brick and PS brick show the same pattern and far from the limit set by USEPA.

Pare bay is one of the areas of significance which is utilized for port services, stevedoring, oil distribution, regional industrial development, aquaculture, cultivation and settlement systems. Pare Bay potentially has a good prospect for a gigantic development. Whilst, a very dangerous threat is pollution, especially heavy metal pollution and water quality degradation. This study aims to determine the current condition of heavy metal concentrations and its distribution on surface waters of Pare Bay. Heavy metals were analyzed using AAS (Atomic Absorption Spectrophotometry) in which it has a minimum detection limit reached 0.001 ppm so that the heavy metal concentration can be well-determined. Hg concentration is higher in the surface ranged 0.01-0.1 mg.l-1. Cd concentration ranged from 0.018-0.083 mg.l-1. Cu concentration ranged from 0.043-0.078 mg.l-1. Pb concentration ranged from 0.111-2.692 mg.l-1. Zn concentration ranged from 0.004 - 0.112 mg.l-1. Heavy metals content in Pare Bay exceeds the standard quality established by Ministry of Environment. It potentially harms the marine life which indirectly reduces the function value of Pare Bay as a center of maritime in the South Sulawesi. Water quality condition play a role in inducing the toxicity level of heavy metals in the Pare Bay. So that this area need to be monitored the water quality sustainably.

Este trabalho apresenta resultados da avaliação da qualidade da água na secção do Rio São Francisco no segmento entre Três Marias e Pirapora. Foram monitorados parâmetros físico-químicos e os elementos Zn, Cd, Pb, Cr, Co, Cu, Ba, Ni, Al, Mn, Ca, Mg e Fe durante um ano; as concentrações dos metais foram obtidas por leitura em ICP-OES. Vários elementos apresentaram altos níveis de contaminação nas áreas urbano-industriais de Três Marias e Pirapora. No segmento de influência rural entre os dois centros urbanos e a jusante de Pirapora, foram observadas alterações para os metais pesados (Cd, Cu, Cr, Co e Ni), que evidenciam a necessidade de um estudo de contaminação dos solos agrícolas, principalmente irrigados, na região. A variação sazonal marca a diferença da qualidade da água no segmento no que se refere aos metais em suspensão com maiores concentrações na estação chuvosa. O Índice de Contaminação foi definido pela razão entre a concentração encontrada e os limites ambientais da Resolução Conama 357/2005. Os resultados evidenciam a degradação da qualidade da água nos centros urbano-industriais, cujos altos Ic decorrem das elevadas concentrações de Zn, Cd, Cu, Cr e Ni. Chamam atenção principalmente os valores que foram obtidos para os metais dissolvidos devido à maior possibilidade de efeitos tóxicos.. Ressalta-se a necessidade de intervenção nas áreas de maior Ic adjacentes aos centros urbano-industriais visando a melhorar a qualidade da água e responder à população local que tem forte relação com o Rio São Francisco.Palavras-chave: Metais Pesados, Qualidade da Água, Índice de Contaminação, Rio São Francisco e Uso do Solo. ABSTRACT: HEAVY METALS AND WATER QUALITY OF THE SÃO FRANCISCO RIVER IN SEGMENT BETWEEN TRÊS MARIAS AND PIRAPORA –MG: INDEX OF CONTAMINATION. This work presents heavy metal concentration measurements taken across a section of the São Francisco River, between Três Marias and Pirapora, to evaluate water quality. The physicochemical parameters and the elements Zn, Cd, Pb, Cr, Co, Cu, Ba, Ni, Al, Mn, Ca, Mg and Fe were monitored during a one year period; the concentration levels of metals were determined by ICP-OES. High contamination levels were found for many elements in Três Marias and Pirapora urban-industrial areas. The section under rural influence, located between the two urban areas and downstream from Pirapora, presented anomalous heavy metal (Cd, Cu, Cr, Co and Ni) readings. That indicates that soil contamination studies are needed, especially on irrigated soil, in agricultural areas within the region. The index is defined by the ratio between the concentrations found which results from environmental limits established by Resolution CONAMA 357/2005. The results show the degradation of water quality in urban-industrial centers, which high rates of contamination result from high concentrations of Zn, Cd, Cu, Cr and Ni. The values obtained for dissolved metals are especially worth of attention, due to the greater risk of toxic effects caused by them. We stress the need for intervention in the areas showing the highest contamination index - which are located next to urban-industrial centers - to improve water quality and meet the expectations of the locals, whose lives are strongly intertwined with the São Francisco River.Keywords: Heavy Metals, Water Quality, Contamination Index, São Francisco River and Soil Use

Water samples of six sampling sites (two downstream, two abattoir sites and two upstream sites) were analyzed using standard methods to determined and assessed heavy metal content of abattoir effluent on surface water quality of River Katsina-Ala, Benue State, Nigeria for rainy and dry seasons. Rainy season heavy metals results were; Cr6+ (0.032+0.06mg/l); Mn2+ (0.16+0.034mg/l); Cu2+ (0.86 +0.46mg/l); Pb2+(0.006+0.002mg/;Cd2+(0.0023+0.004mg/l) and the dry season results were: Cr6+(0.028+0.007mg/l); Mn2+(0.07+0.05mg/l); Cu2+(0.85+0.16mg/l); Pb2+(0.0030+0.014mg/l); Cd2+(0.0021+0.012mg/). Most heavy metals for both seasons were within the maximum permissible limit set by Federal Ministry of Environment, Nigeria (1991). The mean concentrations of Zn2+(1.70+0.29 mg/l) for rainy season and Zn2+(1.33+0.23mg/l) dry season were above the control and standard safe limits of < 1mg/l FMEnv (1991) for surface water quality. There was no significance difference (p<0.05) between the means from upstream and downstream sites for both seasons; though significance difference (p<0.05) existed at the abattoir sites. River Katsina –ala is slightly polluted. Heavy metal content from effluents from abattoir contributed to upset the physicochemical balance of the river. Bioaccumulation and bio-magnification of heavy metals may occur from prolong usage of the river water for drinking. It is suggested that the abattoir effluent be treated before discharge into the river to reduce environmental and health hazards.
