Lumbriculus variegatus and Diporeia spp. were exposed to two contaminant pairs 3H-benzo[a]pyrene (BaP) and 14C-2,4,5,2'4',5'-hexachlorobiphenyl (HCBP), and 3H-pyrene (PY) and 14C-3,4,3',4'-tetrachlorobiphenyl (TCBP) sorbed to each of seven field-collected sediments of varying composition. Toxicokinetic coefficients, bioaccumulation factors (BAF), and biota-sediment accumulation factors ([BSAF],...

Meat is part of duck carcass mostly consumed by humans compared to other parts. This study aimed toanalyze the heavy metal bioaccumulation factor (BAF) meat and its possible risks human health. Atotal 25 samples with their drinking water feed were taken from five intensive farms in CentralJava Province, i.e., Semarang (A), Temanggung (B), Magelang (C), Pati (D) Salatiga (E). Heavy metalsconcent...

The incorporation of heavy metals contained in soils into the food chain is mediated by plants. Plants show varying abilities to take up and accumulate these elements during vegetative growth. In this study, changes content, rate uptake, accumulation, translocation six stages development pea plants were determined. field experiments, two cultivars cultivated consecutive growing seasons. harvest...

Kadmium (Cd) merupakan logam berat berbahaya yang dapat mengakibatkan terjadinya pencemaran di perairan. Penelitian ini bertujuan untuk mengetahui kandungan Cd pada matriks air, sedimen, dan ikan nilem (O. hasselti) Sungai Tajum, Banyumas serta tingkat berdasarkan Single Pollution Index (Pi), Contamination Factor (CF), of Geoaccumulation (Igeo), Bioaccumulation (BAF), Estimated Daily Intake (ED...

This study aimed to assess the levels of rare earth elements and yttrium (REY) vanadium (V) in soils cultivated with citrus, oil palm black pepper eastern Amazon . The potential risk contamination was estimated using enrichment (EF) bioaccumulation (BAF) factors. results showed that pH, K, P significantly affected REY concentrations. europium most significant among studied elements. contents V ...

Contamination of heavy metals would threaten the water and soil resources; phytoremediation can be potentially used to remediate metal contaminated sites. We constructed the Phragmites australis artificial floating wetlands outside the Qingcaosha Reservoir in the Yangtze Estuary. Water characteristic variables were measured in situ by using YSI Professional Pro Meter. Four heavy metals (copper,...

Concentrations of As, Cu, Fe, Hg, Pb and Zn and activity concentrations from 234,238U and 210Po in water, fillet, liver and gills were determined in three stocked fish species from the Luis L. Leon reservoir, located in Northern Mexico. The considered species were Lepomis cyanellus, Cyprinus carpio and Ictalurus furcatus. 238U and 234U activity concentration (AC) in fillet samples showed values...

The transfer of Pb from the soil to crops is a serious food hygiene security problem in China because of industrial, agricultural, and historical contamination. In this study, the characteristics of exogenous Pb transfer from 17 Chinese soils to a popular wheat variety (Xiaoyan 22) were investigated. In addition, bioaccumulation prediction models of Pb in grain were obtained based on soil prope...
