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.

Fishing port scan support fishery resources management by incorporating social-economic activities to improve the local community's welfare; however, it can also negatively impact the environment by increasing waste pollution to the surrounding waters. Kutaraja Fishing Port, Banda Aceh, is one of the active fishing ports that conduct multiple activities, such as industrials, transportations, and domestic activities threatening the environment through the production of pollution such as heavy metals. The purpose of this study is to determine the concentration of heavy metals Zinc (Zn) and Chromium (Cr) and the sediment contamination level in the Kutaraja Fishing Port, Banda Aceh. This research was conducted in February 2021 at the water site of Samudra Kutaraja Fishing Port, Banda Aceh, and sampled sediments using the purposive sampling method. Samples were then analyzed for heavy metal concentration using the Atomic Absorption Spectrophotometer (AAS) instrument in the laboratory of the Aceh Industrial Research and Standardization Center (BARISTAND). The results showed that the concentration of heavy metal Zn ranged from 15.6507 - 27.2939 mg/kg. The majority of heavy metal Cr concentrations were below the test limit of 0.000, except at station 2, which was 9.1212. Both heavy metal concentrations are still categorized as low contamination criteria and still below the Australian and New Zealand Environment and Conservation Council (ANZECC, 2000) and the Canadian Council of Ministers for the Environment (CCME, 2002). This research proved that both heavy metals do not threaten the biota and have a low contamination level in the waters.Keywords:SedimentHeavy metal (Zn)Heavy metal (Cr)Atomic-absorptionSpectro-photometerAssessment

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.
