When young children do not receive adequate amounts of the micronutrient iodine in their diet, their growth and cognitive development can be impaired. Nearly every country in the world has programs in place to track iodine intake and provide supplemental iodine if needed, usually in the form of fortified salt. The iodine nutrition status of a population can be tracked by monitoring iodine level...

This study's focus was to develop a potential pathway for recycling of the paper mill sludge compost (PMSC) in brick making. Composting reduces (PMS) moisture content considerably and shredding becomes easier. The addition PMSC leads an increase porosities bricks makes them lighter, besides delivering energy firing process from burning organics. Lighter construction materials help minimize outl...

In situ immobilization of heavy metals in sediments has been considered as a low-cost and eco-friendly remediation method. this study, biochar (BC) BC-nanoscale zero-valent iron composite (nZVI/BC) treatments with different doses were conducted to immobilize Cd situ. The performance BC nZVI/BC changing mobility bacterial community sediment was investigated, their efficiencies at various pH valu...

In this study, a high-performance mortar (HPM) was produced using fly ash as an alternative binder to increase the strength and solve problem regarding environmental degradation due harmful elements content in ash. The used study obtained from NII Tanasa Power Plant. assessment of leaching test only for HPM containing high volume (40%) compared initial After performing compressive strength, wer...

This paper presents parts of the results from a research project sponsored by Taiwan Environmental Protection Administration (TEPA), investigating both the physical and environmental properties of asphalt mixtures using different amount of incinerator bottom ash (IBA) as fine aggregate substitution. The Marshall mix design method was used to determine the design asphalt content and evaluate the...

In this study, we studied the influence of dosage modified bamboo charcoal (KAM-500-400-3) on fixation effect single Cu(II)-contaminated and mixed Cu(II)–Cd(II)-contaminated sediment. The results showed that it could effectively fix heavy metals in both sediment types. sediment, when amount added KAM500-400-3 was greater than or equal to 5%, Cu(II) content overlying pore water substantially red...

Previous work with leaching of metals from several fly ashes (both class F and class C) indicated minimal potential of leaching of toxic levels of metals from most fly ashes tested. Also, mixing fly ash with soil and other amendments (phosphate fertilizer) significantly decreases Cr, Li, Pb, and Cd in the leachate. One concern is that the characteristics of fly ash may be changed by the additio...

Copper toxicity in 17 Chinese soils was screened using a substrate-induced nitrification assay to generate information for the development of a terrestrial biotic ligand model (tBLM). The leaching effect on the Cu toxicity thresholds was investigated. Both the total Cu-based median effective concentration (EC50) values (46.9-2726 mg/kg) and the solution Cu-based EC50 values (0.04-2.91 mg/L) in ...
