Kota Makassar merupakan pusat kota di Provinsi Sulawesi Selatan yang memiliki aktifitas wilayah pesisir, seperti pemanfataan industri, pariwisata, transportasi laut serta memiliki dua sungai besar yang muara di perairan. Penelitian ini bertujuan untuk mengetahui konsentrasilogam berat dalam air dan sedimen serta menentukan status mutunya. Pengamatan dilakukan pada 10 lokasi strategis sumber pencemar seperti pabrik, hotel, muara sungai serta pelabuhan dengan mengambil sampel air dan sedimen dan selanjutnya dianalisis di laboratorium untuk logam berat Cd, Cr, Hg, Zn, Cu dan Pb. Statistik deskriptif digunakan untuk menganalisis data yang ada. Metode Indeks Pencemar dan Storet (Storage and Retrieval) digunakan untuk menentukan status mutu air dan sedimen dari logam berat untuk biota laut. Hasil penelitian ini menunjukkan perairan Kota Makassar tergolong dalam kategori “Cemar Ringan” berdasarkan hasil perhitungan indeks Pencemar sedangkan status mutu perairan tergolong “Cemar Berat”. Parameter logam berat di kolom perairan yang melampaui baku mutu adalah Krom (0,016±0,005) dan Tembaga (0,112±0,035). Sedangkan untuk parameter logam berat sedimen secara keseluruhan masih berada dalam ambang batas baku mutu yang telah ditentukan. Kondisi tercemar berasal dari aktifitas reklamasi pantai serta sumber alami dan limbah domestik dari aktifitas masyarakat cukup tinggi.ABSTRACTMakassar City is the city center in South Sulawesi Province which has coastal area activities, such as the use of industry, tourism, sea transportation and has two large rivers that estuary into the waters. This study aims to determine the concentration of heavy metals in water and sediment and determine their quality status. Observations were made at 10 strategic locations of pollutant sources such as factories, hotels, river mouths, and ports by taking water and sediment samples and then analyzed in the laboratory for heavy metals Cd, Cr, Hg, Zn, Cu, and Pb. Descriptive statistics are used to analyze the existing data. The Pollutant Index and Storet (Storage and Retrieval) method is used to determine the status of water and sediment quality of heavy metals for marine biota. The results of this study indicate that the waters of Makassar City are classified as "Lightly Polluted" based on the results of the calculation of the Pollutant index while the status of the water quality is classified as "Heavy Polluted". Parameters of heavy metals in the water column that exceed the quality standard are chromium (0,016±0,005) and copper (0,112±0,035). Meanwhile, the parameters of the sediment heavy metals as a whole are still within the specified quality standard. Polluted conditions derived from coastal reclamation activities as well as natural sources and domestic waste from community activities are quite high.

Dahuangpu Wetland is the nature reserve of Tianjin City. The nitrogen, phosphorus and heavy metals contents and releasing of sediment in Dahuangpu Natural Wetland were studied in this paper. The results indicated that the contents of TN and TP in the wetland sediment were lower than the Lowest Effect Level (LEL) in the Guidelines for the Protection and Management of Aquatic Sediment Quality in Ontario, Canada (PSQGs), which means the sediment had no great eco-toxicity on dwelling organisms. Meanwhile the contents of heavy metals, namely Cr, As, Zn, Ni, Pb, Cu, Hg and Cd, in Dahuangpu Wetland sediment were lower than LEL of PSQGs and lower than primary standard of Environmental quality standard for soils (GB15618-1995). Moreover the influence of nitrogen, phosphorus and heavy metals releasing on wetland water qualities were trivial.

Abstract Addis Ababa City’s river ecosystem is under extreme pressure as a result of inappropriate practices of dumping domestic and industrial wastes; thus, threatening its ability to maintain basic ecological, social and economic functions. Little Akaki River which drains through Addis Ababa City receives inorganic and organic pollutants from various anthropogenic sources. Most of inorganic pollutants such as toxic heavy metals released into the river are eventually adsorbed and settle in the sediment. The objective of this study was to evaluate the enrichment levels, pollution load and ecological risks of selected heavy metals (Zn, Cr, Cd and Pb) using various indices. The mean concentrations of heavy metals in Little Akaki River sediment were: Zn (78.96 ± 0.021–235.2 ± 0.001 mg/kg); Cr (2.19 ± 0.014–440.8 ± 0.003 mg/kg); Cd (2.09 ± 0.001–4.16 ± 0.0001 mg/kg) and Pb (30.92 ± 0.018–596.4 ± 0.066 mg/kg). Enrichment factor values indicated that sediments were moderate to significantly enriched with Zn and Cr; moderate to very highly enriched with Pb, and very highly enriched in all sampled sites with Cd. Geo-accumulation index and contamination factor values indicated that the sediments were moderate to very highly contaminated with toxic Cd and Pb. The decreasing order of pollution load index (PLI) in downstream was: (S9) > (S4) > (S8) > (S3) > (S6) > (S10) > (S5) > (S2) > (S7) > (S1). PLI and hierarchical cluster analysis revealed that the highest pollution load occurred in the lower course of the river (S9) which may be due to metals inputs from anthropogenic sources. The ecological risk (RI = 350.62) suggested that the contaminated Little Akaki River sediment can pose considerable ecological risks of pollution. The concentrations of Zn, Cr, Cd and Pb in Little Akaki River sediment surpassed eco-toxicological guideline limits of USEPA (threshold effect concentration) and CCME (Interim Sediment Quality Guidelines). Thus, the contaminated sediments can pose adverse biological effects on sediment dwelling organisms.

AbstractThe aim of the study was to evaluate the impact of potential pollution sources, mainly from the upstream anthropogenic sources and port-related activities. The in-vestigated area covered a wide range of anthropogenic im-pacts (e.g., industrial wastes, storm water runoff, acciden-tal oil spills, intentional discharges and shipping activities). The quality of water and Sediments was assessed us-ing Standard methods, as physical-chemical parameters, chemistry and biology (microbiology, ecotoxicology) aim-ing to figure the level of pollution and the effect of port-related activities. Seawater quality results agreed generally with environmental Standards. Though, in some samples the concentrations of sulphates (mg/1) and heavy metals (μg/1), as B, As and Se exceeded the recommended lim-its, without posing a serious environmental concern. Most of the surface sediment samples contain critical levels of hydrocarbons (C>12), (mg/kg), polycyclic aromatic hydrocarbons (ng/g) and polychlorobiphenyls (ng/g). For some heavy metals (mg/kg), exchangeable concentrations were found to be very close or above the regulations. The signifi-cance of this study is incontestable taking into account the lack of previous relevant historical data of this area. In this sense, it was possible to indicate, in general, good environmental conditions, despite the industrial and concentrated local port-related activities in the investigated area.

<p>Bangka Island is rich in natural resources particularly tin minerals. The increasing of tin mining has elevated various wastes such as tailings, oil, and fuel coming from the sand scraper tin boat. These wastes containing toxic heavy metals may harmful to marine organism. Measurement of Pb, Cd, Cu, Zn, and Ni were carried out in September 2010. The purpose of this research was to predict the pollution degree of Pb, Cd, Cu, Zn, and Ni in sediment using two different methods namely geoaccumulation index (I_geo) and pollution load index (PLI). The samples of sediments were collected at 20 stations using Gravity Core. The content of heavy metals in all samples was determined using Atomic Absorption Spectrophotometer with a mixture of air and acetylene flame. The results showed that there was a different of prediction on sediment pollution level between Load Pollution Index with Geoaccumulation Index. According to Load Pollution Index, sediments in this waters were not polluted by Pb, Cd, Cu, Zn, and Ni (PLI&lt;1). Based on Geoaccumulation Index, sediment were also not polluted by Pb, Cu, Zn, and Ni (Igeo&lt;0). While for Cd, sediments divided into three categories, namely not polluted (Igeo&lt;0), light polluted (0&lt;Igeo&lt;1), and medium pollued (1&lt;Igeo&lt;2).  The concentration of the heavy metals still lower than that sediment quality guideline values.</p> <p>Keywords: Bangka Island, heavy metals, geoaccumulation index, pollution load index.</p>

Despite many good policies and institutions, the coastal environment of Langkawi continues to deteriorate. This could be due to lack of effective governance as well as unregulated waste discharge. Evidences collected from the literature during 1996 to 2013 also revealed a significant increase in the concentrations of Zn (R2 = 0.78) and Pb (R2 = 0.12) in the sediment. This appears to be the result of large volume of terrestrial runoff that brings these metals originating from extensive anthropogenic activities. It is a vital indicator of coastal pollution. It is a matter of concern that in many cases Pb concentration in the sediment exceeded the world average value 20 μg/g as well as Canadian Interim Sediment Quality Standard of 35 μg/g for the coastal areas. Similarly, the metal pollution index (MPI) measured over a period of 2007 to 2009 in fish also indicated an increasing trend of pollution in Langkawi. The maximum MPI value (4.87) was recorded in Spanish mackerel. Since pollution of coastal environment has serious implications for marine biodiversity and health of seafood consumers, measures are required to address this problem. Use of constructed wetland might be effective in reducing the coastal pollution as this will filter the effluent and waste before their mixing with the coastal water. Furthermore, enabling the stakeholders to play the environmental stewardship role will ensure better governance of coastal ecosystem and effective implementation of policies, envisaging an improved monitoring of waste/effluent discharge into the coastal marine environment. These measures are among the actions necessary for achieving a sustainable coastal environment of Langkawi.

Background: Sediments in the aquatic ecosystems can be used as suitable indicators for monitoring contaminants. Then, objectives of this study were to evaluate the concentration of heavy metals in the surface sediments of the Mohammad Abad River, to determine the degree of pollution of heavy metals in sediments using some major contamination indices; to identify the major sources (anthropogenic or natural sources) of the studied metals; and to evaluate the “reference river” of the river under study for ecotoxicology studies. Methods: Samples of sediment were taken from six sites of the river. The present study, eleven heavy metals (chromium, manganese, iron, cobalt, nickel, zinc, selenium, magnesium, silver, aluminum and arsenic) were studied. Results: Comparison of metal concentrations with those of Sediment Quality Guidelines (SQGs) showed no association with harmful biological effects for the heavy metals studied except for Se and As. The results of the contamination factor index showed low pollution levels for most metals (Cr, Mn, Fe, Co, Ni, Zn and Al), moderate pollution levels for As, and very high pollution levels for Se. The degree of contamination (Cd) and modified degree of contamination (mCd), showing the total contamination of elements, demonstrated very high degree contamination status in the study area. According to the index of quantification of contamination, the values of Cr, Mn, Fe, Ni, Zn and Al were derived mainly from geogenic sources of enrichment, while the values for Se and As were enriched by anthropogenic source of enrichment. Conclusion: These findings suggest that continuous monitoring of Se and As in sediment and organisms of the Mohammad Abad River should be directed to evaluate the threat of these elements to the public health and to the ecology of the river under study.

Distribution of heavy metals (Hg, Cu, Pb, Zn, Cd and Cr) in the seawater and sediments were studied based on data from two oceanographic surveys carried out in Liaodong Bay in May and October 2016. The results showed that the values of heavy metals in seawater represent a uniform distribution, while no trends were detected for spatial distribution. High values of heavy metals in sediment were generally distributed nearshore areas in October. Concentrations of Pb, Zn, Hg in seawater were higher than the national guideline values of Mar. sediment quality of China. Values of Cu, Zn, Cd and Hg were higher than the national guideline values of Mar. sediment quality of China in October, while quality was in good condition in May. Correlation analysis showed that TOC was mainly contributed for the variations of heavy metals. The potential ecological risk analysis of heavy metals indicates that Hg, Cd and Cu should be listed as the priority contaminant metals in Liaodong Bay.
