The present study investigated contamination of polybrominated diphenyl ethers (PBDEs) in sediment and fish samples collected from rivers in Guiyu, China where electronic waste (e-waste) is recycled and disposed. PBDE congeners with mono-to hepta-brominated and deca-brominated substitutions were detected using (13)C(12) isotope dilution GC/MS/MS and GC/MS methods, respectively. The total PBDE c...

BACKGROUND Multiple food intolerance in infants, including intolerance to extensively hydrolysed proteins (HP), is often difficult to treat. However, few data have been reported on clinical outcome and dietary treatment of these patients. AIMS To evaluate the clinical characteristics of patients with HP-intolerance and the long-term outcome of treatment with ass' milk. PATIENTS AND METHODS ...

By-product and waste streams from the food industry could be regarded as ideal renewable feedstocks for the production of value-added products. The utilisation of food processing wastes could lead to the development of a sustainable chemical industry and a food industry that will cause less environmental concerns. This will be achieved via simultaneous substitution of fossil raw materials and r...

Hydrothermal carbonization (HTC) is a promising technology used for bioenergy conversion from bio-wastes such as sewage sludge, livestock manure, and food waste. To determine the optimum HTC reaction temperature in maximizing the gross energy recovery efficiency of poultry slaughterhouse sludge cake, a pilot-scale HTC reactor was designed and operated under reaction temperatures of 170, 180, 19...

Aquaponics is the science of integrating intensive fish aquaculture with plant production in recirculating water systems. Although ion waste production by f ish cannot satisfy all plant requirements, less is known about the relationship between total feed provided for f ish and the production of milliequivalents (mEq) of different macronutrients for plants, especially for nutrient flow hydropon...

Biodiesel is a non-petroleum fuel designed to run in a diesel engine. It can be made from a variety of different feedstocks, including virgin vegetable oil, waste cooking oil, and animal fats. The aim of this research was to compare and contrast biodiesel made from fish oil to other more traditional sources. In this paper I examined traditional biodiesel feedstocks available in coastal Alaska. ...

AquaFuture operates a 1.8 million gallon recirculating aquaculture facility capable of filtering the waste products from over three quarters of a million fish that are fed over one million pounds of feed per year. This paper describes a compact system for effluent treatment and residuals management that has proven effective at maintaining water quality within compliance limitations. Solids are ...

The acute fish test is an animal test whose ecotoxicological relevance is worthy of discussion. The primary aim of protection in ecotoxicology is the population and not the individual. Furthermore the concentration of pollutants in the environment is normally not in the lethal range. Therefore the acute fish test covers solely the situation after chemical spills. Nevertheless, acute fish toxici...

Broiler is a readily available meat source catering the need of meat eating people. The disposal of broiler waste such as carcasses, blood, feather and offal produced from slaughtering broiler birds need to be disposed or utilized properly. Considering this, the present study was purposively conducted in Nagapattinam district of Tamil Nadu to identify the existing disposal method and recommend ...
