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.

There is continuous deterioration of freshwater systems globally due to excessive anthropogenic inputs, which severely affect important socio-economic and ecological services. We investigated the water and sediment quality at 10 sites along the severely modified Swartkops River system in the Eastern Cape Province of South Africa and then quantified the phytoremediation potential by native and non-native macrophyte species over a period of 6 months. We hypothesized that the presence of semi and permanent native and non-native macrophytes mats would reduce water and sediment contamination through assimilation downriver. Our results were variable and, thus, inconsistent with our hypotheses; there were no clear trends in water and sediment quality improvement along the Swartkops River. Although variable, the free-floating non-native macrophyte, Pontederia (=Eichhornia) crassipes recorded the highest assimilation potential of heavy metals in water (e.g., Fe and Cu) and sediments (e.g., Fe and Zn), followed by a submerged native macrophyte, Stuckenia pectinatus, and three native emergent species, Typha capensis, Cyperus sexangularis, and Phragmites australis. Pollution indices clearly showed the promising assimilation by native and non-native macrophytes species; however, the Swartkops River was heavily influenced by multiple non-point sources along the system, compromising the assimilation effect. Furthermore, we emphasise that excessive anthropogenic inputs compromise the system’s ability to assimilate heavy metals inputs leading to water quality deterioration.

Sungai Waelata dan Sungai Anahoni merupakan dua sungai tempat beroperasinya trommel untuk pengolahan material emas Gunung Botak dan Gogrea. Melalui aliran sungai, limbah merkuri hasil pengolahan trommel terangkut dan terbawa ke muara yang pada akhirnya akan mencemari perairan laut Teluk Kayeli. Kerang Polymesoda erosa merupakan salah satu jenis kerang yang sering digunakan dalam pemantauan logam berat merkuri, terutama pada wilayah muara sungai. Penelitian ini bertujuan untuk menganalisis kadar logam berat merkuri(Hg) pada air, sedimen dan kerang Polymesoda erosadi Muara Sungai Waelata dan Sungai Anahoni Kabupaten Buru. Hasil penelitian menunjukan konsentrasilogamberat merkuripada air di Muara Sungai Waelata dan Sungai Anahoni tidak terdeteksi di semua stasiun penelitian dan dibawah baku mutu air laut untuk biota laut berdasarkan Kepmen LH No. 51 Tahun 2004 sebesar 0,001 ppm. Konsentrasilogamberat merkuripada sedimenmemilikikisaranrata­ratasebesar0,134­0,874ppm dan dibawah baku mutu sedimen berdasarkan ANZECC/AMRCANZ (2000) sebesar 1,0 ppm. Konsentrasilogamberat merkuripada kerang Polymesoda erosamemilikikisaranrata­ratasebesar0,123­0,206 ppm dan dibawah Batasan Maksimum Cemaran Logam Berat Dalam Pangan merujuk pada Standar Nasional Indonesia (SNI) No. 7387 Tahun 2009 sebesar 1,0 ppmABSTRACT The Waelata River and the Anahoni River are the two rivers where trommel operates for the processing of gold material from Gunung Botak and Gogrea. By the river, mercury waste from the processing of trommel is transported through estuary which will ultimately pollute the waters of the Kayeli Bay. Polymesoda erosa shells are one type of shellfish that is often used in monitoring heavy metals of mercury, especially in the estuary region. This study aims to analyze the concentration of heavy metal mercury (Hg) in water, sediments and Polymesoda erosa shells in the Waelata River and Anahoni River in Buru Regency. The results showed that the concentration of mercury heavy metals in water in the Waelata River and Anahoni River were not detected at all research stations and were below sea water quality standard for marine biota based on Minister of Environment Decree No. 51 of 2004 which is 0.001 ppm. The concentration of mercury heavy metals in sediments has an average range of 0.1340.887 ppm and is below the sediment quality standard based on ANZECC/AMRCANZ (2000) of 1.0 ppm. The concentration of mercury heavy metals in Polymesoda erosa shells has an average range of 0.1230.206 mg/kg and under the Maximum Limit of Heavy Metal Contamination in Food refers to the Indonesian National Standard (SNI) No. 7387 of 2009 which is 1.0 ppm.

The surface water system of Amsterdam is very complicated. Of two characteristic types of water systems the influences on water and sediment quality are investigated. The importance of the sewer output to the total loads is different for both water systems. In a polder the load from the sewers is much more important than in the canal basin. Measures to reduce the emission from the sewers are much more effective in a polder. The effect of these measures on sediment quality is more than the effect on water quality. Some differences between a combined sewer system and a separate sewer system can be found in sediment quality.
