“…In the end, these rivers and canals discharge their loads into the coastal Level of As was the highest amongst the others, especially in the Frigate Tuna (Table 3). Arsenic (As) compounds, both organic and inorganic, which are differ greatly in chemical nature (speciation) and bioavailability, discharge into the environment through geological process (geo-genic), anthropogenic process (human activities), also small amounts of them by various biological sources (biogenic) that are rich in As (Mahimairaja, Bolan, Adriano, & Robinson, 2005). Arsenic is a ubiquitous and potentially toxic trace …”

Aquatic environment of Jakarta Bay have already been highlighted due to its heavy metals contamination which may lead into food safety concern of fisheries products derived from this region. This research aimed to investigate bioaccumulation level of heavy metals (Pb, Cd, and As) in fish and mussels from Jakarta Bay, as a human risk assessment of seafood consumption. Samples of mussels and fish were taken from Penjaringan, Tarumanegara, Cilincing, and Tanjung Pasir district. Bioaccumulation of heavy metals was analyzed by Inductively Coupled Plasma -Mass Spectrometry technique. Results of the study revealed that metals bioaccumulation in fisheries products were varied, with As (Arsenic) as the highest metal contaminant (0.68 mg/kg, dry weight). Furthermore, estimated daily intake (EDI), target hazard quotient (THQ), total target hazard quotient (TTHQ), and safety limits prescribed by various agencies, showed that consumption of fisheries products from Jakarta Bay considered as relatively safe for human health in total of food ingestion rate of fish 57.34 g/day. These results are expected to serve as a baseline to construct preventive and palliative policies for food safety of fisheries products from Jakarta Bay.

“…The majority of environmental As contamination is geogenic from the weathering and erosion of As-bearing rocks, minerals and ores [2]. There has also been considerable release of anthropogenic As into soils from insecticides, herbicides, wood preservatives and mine wastes [3]. These releases have led to localised but highly As contaminated soils worldwide.…”

In situ arsenic oxidation and sorption by a Fe-Mn binary oxide waste in soil., Journal of Hazardous Materialshttp://dx.doi.org/10. 1016/j.jhazmat.2017.08.066 This is a PDF file of an unedited manuscript that has been accepted for publication.

Graphical abstractHighlights  A Fe-Mn binary oxide waste is used to remediate As contaminated soils. As(III) and As(V) adsorption capacities of 70 mg g 1 and 32 mg g 1 were determined. The bioaccessibility of total As was significantly reduced by 7.80 %  Arsenic in the contaminated soil effectively binds to the exogenous binary oxide. As(V) was sorbed by mononuclear bidentate corner-sharing with Fe. AbstractThe ability of a Fe-Mn binary oxide waste to adsorb arsenic (As) in a historically contaminated soil was investigated. Initial laboratory sorption experiments indicated that arsenite [As(III)] was oxidized to arsenate [As(V)] by the Mn oxide component, with concurrent As(V) sorption to the Fe oxide. The binary oxide waste had As(III) and As(V) adsorption capacities of 70 mg g 1 and 32 mg g 1 respectively. X-ray Absorption Near-Edge Structure and Extended X-ray Absorption Fine Structure at the As K-edge confirmed that all binary oxide waste surface complexes were As(V) sorbed by 3 mononuclear bidentate corner-sharing, with 2 Fe at ~ 3.27 Ǻ The ability of the waste to perform this coupled oxidation-sorption reaction in real soils was investigated with a 10% by weight addition of the waste to an industrially As contaminated soil. Electron probe microanalysis showed As accumulation onto the Fe oxide component of the binary oxide waste, which had no As innately. The bioaccessibility of As was also significantly reduced by 7.80 % (p < 0.01) with binary oxide waste addition. The results indicate that Fe-Mn binary oxide wastes could provide a potential in situ remediation strategy for As and Pb immobilization in contaminated soils.

Abstract-To compare the dry matter yield and iron uptake of Brassica chinensis, soil iron content at 15, 23, 31, 39 days after transplanting the seedlings of Brassica chinensis with respect to different concentration of landfill leachate concentrations at 0, 33.3, 50 and 100% application on soil were measured. Treated B. chinensis with 100%, 50% and 33.3% leachates increased in dry matter yield by 59.2%, 66.4% and 95.7% respectively compared to control irrigated water. The highest and lowest iron uptake by B. chinensis observed at fifteen and twenty-three days after transplanting respectively. The iron concentrated in soil showed significant differences only at twenty tree days after transplanting the seedlings of B. chinensis to 100, 0, 33.3 and 50% of landfill leachate concentrations respectively.Index Terms-Brassica chinensis, iron, landfill leachate.
