Mercury exposure is the second-most common cause of toxic metal poisoning. Public health concern over mercury exposure, due to contamination of fish with methylmercury and the elemental mercury content of dental amalgams, has long been a topic of political and medical debate. Although the toxicology of mercury is complex, there is evidence for antioxidant protection in the prevention of neurolo...

ORGANOHALOGEN COMPOUNDS – Volume 66 (2004) 1489 Introduction During the last years there were several reports on the appearance of the biocides triclosan (TCS; 5chloro-2-(2,4-dichlorophenoxy)phenol; CAS No. 3380-34-5) and chlorophene (CP; 4-Chloro-2(phenylmethyl)phenol; CAS No. 120-32-1) in the environment. TCS is used in numerous personal care products like toothpaste and soaps, but also in te...

Abstract This study evaluates the potential of local fish waste oil as a feedstock for biodiesel via supercritical methanol transesterification (SCMT). Hexane was used cosolvent and reaction carried out in continuous reactor under conditions. The response surface methodology (RSM) method applied to analyse effect four independent variables, including weight ratio fish-waste (W), temperature (T)...

Abstract. The growth rate of Hermetia illucens larvae in the bioconversion organic waste is influenced by media and environmental conditions where BSF lives. This study aims to determine effect feed formula on waste. research method was carried out rearing larvae, making formulas, determining larval length, weight cassava. results showed that feeding from fish waste, tapioca with a chopped diam...

The purpose of this study was to judge the feasibility of gasification for the disposal of waste streams generated through salmon harvesting. Gasification is the process of converting carbonaceous materials into combustible "syngas" in a high temperature (above 700 degrees C), oxygen deficient environment. Syngas can be combusted to generate power, which recycles energy from waste products. At ...

Fish lipid contains long-chain n-3 (omega-3) PUFA, particularly EPA (C20:5 n-3) and DHA (C22:6 n-3). Consumptions of these PUFAs have been perceived to be important in human nutrition, health and disease prevention. World fish lipid request continue to increase. Fish lipid that contributes to the nutritional needs is currently being extracted from liver or muscle of cod, herring, mackerel and s...

Tetrabromobisphenol A (TBBPA) and hexabromocyclododecanes (HBCDs) were analyzed in 12 tissues of prey (mud carp) and predator (northern snakehead) fish from an e-waste area, South China. The TBBPA concentrations in different tissues ranged from 0.03 to 2.85 ng/g wet weight (ww) in mud carp and 0.04 to 1.30 ng/g ww in northern snakehead. The concentrations of HBCDs ranged from 0.07 to 96.9 ng/g ...

A study was conducted to determine the relation between the consumption of contaminated local fish and concentrations of total polychlorinated biphenyls (PCBs) and 68 PCB congeners in the milk of nursing Mohawk women residing near three hazardous waste sites. From 1986 to 1992, 97 Mohawk women were interviewed and donated at least 50 ml of breast milk. The comparison population consisted of 154...

We recently reported a hazardous waste site in which polychlorinated biphenyls (PCBs) were at such high concentrations in soil that significant levels were found in indoor residential air. This paper uses the waste site to illustrate the complexities in exposure assessment and toxicity assessment of PCBs. Aroclors are commercial mixtures of different arrays of the 209 individual PCB congeners. ...
