The Mean

Seven sediment cores were collected from De Montigny Lake in order to determine concentrations, and contamination assessment of heavy metals such as Cr, Zn, Ni, Pb, Cu, Co and Cd. The mean concentrations of heavy metals are as follows: 48.3 mg/kg for Cr, 36.4 mg/kg for Zn, 20.6 mg/kg for Ni, 14.7 mg/kg for Pb, 10.2 mg/kg for Cu, 6.7 mg/kg for Co and 0.1 mg/kg for Cd. Based on the sediment quality guidelines, the mean concentration metals such as Cr, Cu and Ni exceeded the US Environmental Protection Agency (USEPA) guideline. However, the concentration of Cr was more than the Canadian Water Quality Guidelines for Protection of Aquatic Life (CCME), and Threshold Effect Level (TEL) guidelines. The metal contamination in the sediments was also evaluated using Enrichment Factor (EF) and geoaccumulation index (Igeo) to assess natural and anthropogenic factors. The results of enrichment factor methods demonstrated that sediments from De Montigny Lake were moderately to high enriched, mainly controlled by through anthropogenic activities. According to Sediment Quality Guidelines (SQGs), the concentrations metals from the core sediment of De Montigny Lake are classified as having moderate impacts with potential adverse biotoxic effects.

Pusat Standardisasi Instrumen Kualitas Lingkungan Hidup (PSIKLH) merupakan salah satu instansi yang berada di kawasan Puspiptek dengan kegiatan laboratorium pengujian dan laboratorium kalibrasi. Asesmen kualitas lingkungan di PSIKLH dilakukan mencakup kualitas udara ambien, udara emisi, air, tanah, dan sedimen periode 2018-2020. Pengambilan contoh uji dan analisis parameter mengacu pada metode Standar Nasional Indonesia dan metode lainnya yang sudah baku. Hasil asesmen dibandingkan dengan baku mutu masing-masing parameter sesuai peraturan yang ada. Konsentrasi TSP, PM10, PM2,5, SO2, NO2, dan O3 di PSIKLH hampir semua berada di bawah baku mutu berdasarkan Peraturan Pemerintah No.41/1999 tentang Pengendalian Pencemaran Udara, namun ada 8 dari 28 data PM2,5 berada di atas baku mutu. Konsentrasi H2S dan NH3 berada di bawah baku mutu sesuai Keputusan Menteri Negara Lingkungan Hidup No. 50/1996 tentang Baku Tingkat Kebauan. Pada asesmen tahun 2018, konsentrasi partikulat, SO2, NOx, dan CO pada generator berada di bawah baku mutu berdasarkan PermenLH No. 21/2008. Setelah peraturan baru PP No.15/2019 dikeluarkan, konsentrasi CO dan NOx telah melebihi baku mutu tersebut. PSIKLH mengirimkan limbah bahan berbahaya dan beracun (B3) ke pihak eksternal untuk dapat diolah, sedangkan limbah cair domestik dilakukan pengolahan dan pengujian sebelum dibuang ke lingkungan. Kualitas limbah domestik parameter pH, BOD, COD, minyak lemak, TSS dan amoniak berada di bawah baku mutu berdasarkan Permen LHK No.68/2016 tentang Baku Mutu Air Limbah Domestik. Konsentrasi tanah di PSIKLH dan sedimen sungai di sekitar Kawasan Puspiptek berada di bawah baku mutu berdasarkan Canadian Soil Quality Guidelines for the Protection Of Environmental and Human Health dan juga Canadian Sediment Quality Guidelines for the Protection of Aquatic Life in Freshwater. Pemantauan rutin dan komprehensif lingkungan kawasan perlu dilakukan untuk mengetahui sumber pencemar yang potensial mencemari kawasan Puspiptek sehingga dampak pencemaran dapat diatasi.

La presencia de metales pesados en concentraciones que exceden los límites permitidos por las legislaciones ambientales nacionales e internacionales, alteran el equilibrio de un ecosistema y aunque hay una liberación de los metales pesados por medios naturales, la mayor parte es causada por acciones antropogénicas. Esta investigación determinó las concentraciones de cadmio y plomo en dos especies de moluscos de importancia comercial: concha prieta (Anadara tuberculosa) y pata de mula (A. grandis) y en muestras de agua y sedimento del hábitat circundante de estos organismos. Los resultados revelaron que a concentración de cadmio y plomo en agua en las estaciones 4, 5 y 6 exceden los valores descritos en a legislación ambiental ecuatoriana y en sedimento la presencia de cadmio es más notable debido a que exceden los valores de la Canadian Sediment Quality Guidelines for the Protection of Aquatic Life cuyo valor es de 0.676 ppm y el valor promedio cuantificado en esta investigación fue de 6.92 ppm. En Ecuador no existen normas sanitarias que establezcan límites de contenido de metales en moluscos bivalvos, sin embargo en un estudio de la USAID (2009) se encontraron concentraciones inferiores a 0.1 ppm para cadmio y 0.9 ppm para plomo, mientras que en el presente trabajo se encontraron en promedio 4.24 y 4.01 ppm de cadmio y 3.3 7 y 2.62 ppm de plomo para A. tuberculosa y A. grandis respectivamente, lo que evidencia una alta concentración de estos elementos tóxicos en los organismos objetos de estudio.

Abstract Distribution patterns of selected heavy metals content in sediments from the Bay of Quiberon and Gulf of Morbihan were studied to understand the current heavy metals contamination due to urbanization and mariculture activities in the coastal area. Therefore, a survey was conducted and 196 sediments collected were characterized for heavy metals content using Inductively Coupled Plasma – Mass Spectrometry (ICP–MS) after mix acid digestion process. The distribution maps of the concentrations of the heavy metals studied were produced as an isopleth map based on data interpolation by the ArcGIS software application. The association with the adverse effects to on aquatic organisms were was determined by the classification of the sediment according to the sediment quality guidelines. Therefore, two approaches were employed namely; direct comparison with Sediment Quality Guidelines (SQGs) by USEPA and comparison with other numerical SQGs, threshold effect level/probable effect level, and effect range low /effect range medium. In order to estimate the effect of multiple contaminations of heavy metals, the mean–ERM–quotient was calculated at each sampling points.

Abstract Some aspects of the quality of fish and sediment samples with respect to contamination with organochlorine compounds, polycyclic aromatic hydrocarbons and several metals are addressed. Fish were obtained from three reservoirs: Kyiv, Kremenchuk and Kakhovka. Sediment cores were obtained from Kremenchuk, Zaporizhzhia and Kakhovka. Levels of contaminants in fish showed differences among species within a reservoir and among reservoirs within a species. The major organochlorine compounds found in the fish were DDT and PCBs with levels in the low ng/g range. Fish PCB levels generally tended to be higher in the Upper Kakhovka reservoir than in the other reservoirs and the congener profile suggested a local source of PCBs to that reservoir. Bream from the Kyiv reservoir had higher levels of mercury than bream from the other reservoirs even though they were of relatively small size. Lead-210 profiles in sediment cores suggested that all three cores sampled only recent time; two of the cores extended deeply enough to capture the large increase in cesium-137 from Chernobyl in 1986, and the third consisted only of material deposited after that event. Inputs of cesium-137 were high and there was no indication of decreases since 1986. Polycyclic aromatic hydrocarbons in sediments were also high, especially in the Zaporizhzhia reservoir where concentrations consistently exceeded Canadian sediment quality guidelines by sever-alfold. Concentrations were lower in the Kakhovka reservoir but still in excess of guidelines, and they were lower yet at the most upstream core from Kremenchuk reservoir. A similar pattern was evident with several metals in sediments. Concentrations in the core from Zaporizhzhia exceeded those from Kakhovka which in turn exceeded those from Kremenchuk. Concentrations in both Zaporizhzhia and Kakhovka generally exceeded Canadian sediment quality guidelines. The general picture that emerges is one of a system of widespread chemical contamination not only with Chernobyl byproducts but also with hydrocarbons, metals and organochlorines, with significant sources downstream from the Kremenchuk site.
