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

The effect of seasonal changes on heavy metals concentration in three commonly edible fruits in Enugu State was analyzed. Banana, pineapple and watermelon samples were collected during three rainy season months (June, July and August) from three markets in the three districts of Enugu state (Enugu North, Enugu West and Enugu East). Heavy metals evaluated during the study include lead, cadmium, cobalt, nickel, zinc and copper. Metals in the samples were quantified using atomic absorption spectrophotometry (AAS) at specific wave lengths and values reported in mg/kg. The result of the study showed the maximum and minimum values of heavy metals observed in all the samples were; 0.28 – 0.03 mg/kg, 0.22 – 0.01 mg/kg, 0.13 – 0.01 mg/kg, 0.64 – 0.33 mg/kg, 0.69 – 0.01 mg/kg and 13.88 – 1.42 mg/kg for lead, cadmium, nickel, cobalt, copper and zinc respectively. The quantity of metals in all the samples, on average, reduces as the rainy season month progresses. The order of heavy metal concentrations in the fruit samples from the markets were in the following decreasing order; Nsukka market> Ogbete market> Ezeagu market. Banana fruit showed the highest concentration of heavy metals while watermelon showed the least heavy metal concentration. Values obtained were compared to WHO maximum permissible limit for each metal. Environmental pollution should be prevented in market areas to avoid food poisoning from consumption of contaminated food.

Background: Heavy metals are materials naturally occurring in nature and increase with a rise in human activity. Ex-mining areas and domestic waste from human settlements are sources of heavy metal contamination that enter and pollute water, which then accumulates in various organisms including the Caulerpa racemosa community. The accumulation of heavy metals in C. racemosa has a wide impact on the food chain in aquatic ecosystems and humans because this alga is a consumptive commodity.   Methods: Sampling of C. racemosa was carried out at seven sites on Bintan Island, Indonesia covering the eastern (Teluk Bakau, Beralas Pasir, Malang Rapat), northern (Berakit and Pengudang), western (Sakera), and southern parts (Tg. Siambang). Sampling was carried out during different monsoons, and heavy metals in water and sediment samples were measured to determine the heavy metal concentration. Heavy metals were analyzed by a spectrophotometric method using Atomic Absorption Spectrophotometry.   Results: The results showed that heavy metal concentrations fluctuate according to changes in the wind season, which carry currents and spread pollutants into the water. The concentration of metal in the water is also from anthropogenic activities. The heavy metal content of cadmium (Cd), lead (Pb), copper (Cu), iron (Fe), and zinc (Zn) in C. racemosa is high in locations close to settlements. Meanwhile, in seawater samples, Fe and Zn metals have the highest concentrations compared to others.  Conclusions: Ex-bauxite mines are a source of Fe and Zn metal contamination in the environment, especially at Tg. Siambang. The levels of these heavy metals in the sediment are also high, as surface particle deposits accumulate at the bottom of the sediment. In general, the levels of heavy metals Cd, Pb, Cu, Fe, and Zn increase in the northern monsoon because the dynamics of the water transport greater heavy metal pollution.

Background: The objective of this study was to compare the levels of heavy metals (Pb, Hg, and Cd) and metallothionein (MT) in the gills and stomach of two species of mussels (Crassostrea iredalei and Crassostrea glomerata), and to observe the ability of the mussels to absorb the heavy metals Pb, Hg and Cd present in the water. Methods: The mussels were obtained from Mayangan, Kenjeran and Gresik ports, East Java, Indonesia. MT levels were determined using ELISA. Heavy metal levels of Pb, Hg and Cd were assayed using atomic absorption spectrophotometry. Results: The levels of Pb and Cd in water were below the maximum permissible levels for local water quality standards. By contrast, the level of Hg in the water was above the maximum permissible levels for water quality standards. At Mayangan Port (Station 1), the level of Pb was higher than Hg and Cd. Levels of MT and heavy metals varied greatly among of C. iredalei and C. glomerata individuals, but were always higher in the gills than in the stomach. The highest MT level (160,250 ng/g) was observed at Kenjeran Port (Station 2). MT levels were shown to be significantly associated with heavy metal level (P<0.0001). Conclusions: This result indicates that MT may be responsible for the sequestration of these heavy metals, as has already been observed in terrestrial animals.

The article focuses on the study of change of containing heavy metals (zinc, copper, iron, cadmium, lead, arsenic) in the abiotic and biotic components of the Serepok river (Vietman) influenced by wastewater discharge from industrial areas. Heavy metal content was determined in the river water and bottom sediments in the four zones: above and within the boundaries of industrial regions Xoa Phu and Tam Thang and in two water reservoirs situated below the boundaries of those industrial areas. Tilapia Galilean ( Sarotherodon galilaeus ), Hemibagrus ( Hemibagrus ), and sazan ( Cyprinus carpio ) caught in these areas were the hydrobionts under study in which liver, gills, skeleton and muscles accumulation of heavy metals was detected. In the organs of fish caught in the river within industrial region, heavy metals concentration was 3-7 times higher. The greatest concentration of heavy metals was found in the liver and gills of fish caught in the boundaries of industrial regions, the least concentration was in the muscles. In most cases, significant correlation between heavy metal concentration in organs of fishes and in river water, bottom sediments has been revealed.

Removal Of Heavy Metals

A calcium bentonite from Orasu Nou deposit (Satu Mare Romania) was used as raw material. We have conducted laboratory experiments to determine the influence of bentonite on the degree of heavy metal retention. It has been observed that the rate of retention increases as the heavy metal concentration decreases. Experimental studies have been carried out on metal retention ( Zn) in bentonite. In this paper, we realized laboratory experiments for determining the influence of metal (Zn) on the growth and development of two types of plants (Pelargonium domesticum and Kalanchoe) and the effect of bentonite on the absorption of pollutants. These flowers were planted in unpolluted soil, in heavy metal polluted soil and in heavy metal polluted soil to which bentonite was added to observe the positive effect of bentonite. It has been noticed that the flowers planted in unpolluted soil and polluted with heavy metals to which bentonite has been added, the flowers have flourished, the leaves are still green and the plants whose soils have been polluted with heavy metals began to dry after 6 days, three weeks have yellowish leaves and flowers have dried. Experiments have demonstrated the essential role of bentonite for the removal of heavy metals polluted soil.
