Abstract

In the mangrovesof Blanakan, Indonesia, silvofishery practices may play arole in maintaining the environmental quality of ponds. Mangroves are known as pollutant traps since their root systems absorb and accumulate materials. Heavy metals are pollutants that often contaminate aquatic environment like ponds. The bioconcentration factor can be used to evaluate the content of heavy metals in organisms, while the translocation factor can be used to measure the amount of heavy metals transferred form one organ to another. The aim of this study was to determine the bioconcentration factor and the translocation factor of heavy metals (Pb, Cu,andZn) in mangrovetrees (Avicennia and Rhizopora) at the Blanakan ponds. Samples of mangrove trees from 3 stations, were cut using a knife, and samples of sediments were collected using Ekman Bottom Grab sampler. Samples were then prepared for heavy metal content analysis using the Shimadzu 6300 atomic absorption spectrophotometer. The bioconcentration and translocation factorswere calculated using formulas; the bioconcentration factor was calculated as the content of heavy metals in trees divided by the content of heavy metals in sediments. Results showed that the bioconcentration factor of Cu was higher than 1 in the roots, stems and leaves of Avicennia trees and of Zn was higher than 1 in the roots of Rhizopora trees at station 1. Translocation factors higher than 1 were mostly found in Avicennia (Cu) and Rhizopora (Pb) trees. Mangrove trees with translocation values of greater than 1 for one or more heavy metals can be considered as strong accumulators of the corresponding metals.

Abstract

The Garapan river mouth forms part of the Tanjung Pasir coastal area. This region receives materials not only from coastal waters but also from domestic sewage and industrial wastewater that contains heavy metals such as Cu, Pb, and Zn. On the contrary, the Cibungur river mouth in the different coastal area, receives relatively lower amounts of domestic sewage and industrial wastewater. The objective of this study was to determine the Cu, Pb, and Zn content in the coastal sediment as well as the levels of A.indica and their relationship with water quality parameters. Samples were collected from four stations located in the Garapan and Cibungur river mouths and were analyzed for metal content using atomic absorption spectrometry Shimadzu 6300. Samples of A. indica found in the field are categorized into three diferent size classes. It is because size related to heavy metal accumulation. Results showed that bioconcentration factor (BCF) values were Zn>Cu>Pb in both locations. Small size A. indica tends to have higher values of BCF for Cu and Zn compared to medium and larger sized samples. Furthermore, the BCF values of Cu, Pb, and Zn in A. indica were higher when the sediment had a lower concentration of organic matter.

Abstract

The increased use of motorcycles for transportation has heightened environmental challenges related to their washing, particularly the discharge of untreated wastewater containing heavy metals, such as copper (Cu) and lead (Pb), into drainage systems. This study explored the effectiveness of zeolite-embedded sheets (ZESs) in the removal of these pollutants from motorcycle washing wastewater. ZESs were prepared through treatment of nonwoven sheets with Linder Type A (LTA Zeolite) powder and heat treatment, washing, and drying. Characterization was performed via scanning electron microscopy with energy-dispersive X-ray spectroscopy, and Fourier transform infrared spectroscopy. Over a 60 min adsorption period, the ZES achieved removal efficiencies of 40% for Cu after 30 min and 70% for Pb after 60 min. The results confirm that ZESs are a promising adsorbent for heavy-metal remediation and particularly effective for lead removal in motorcycle washing wastewater.
