Radionuclides in the terrestrial ecosystem near a Canadian uranium mill - Part II: Small mammal food chains and bioavailability
PCB-induced changes of a benthic community and expected ecosystem recovery following in situ sorbent amendment
The benthic community was analyzed to evaluate pollution-induced changes for the polychlorinated biphenyl (PCB)-contaminated site at Hunters Point (HP) relative to 30 reference sites in San Francisco Bay, California, USA. An analysis based on functional traits of feeding, reproduction, and position in the sediment shows that HP is depauperate in deposit feeders, subsurface carnivores, and species with no protective barrier. Sediment chemistry analysis shows that PCBs are the major risk drivers at HP (1,570 ppb) and that the reference sites contain very low levels of PCB contamination (9 ppb). Different feeding traits support the existence of direct pathways of exposure, which can be mechanistically linked to PCB...

Bioavailability of cadmium and zinc to the common carp, Cyprinus carpio, in complexing environments: A test for the validity of the free ion activity model
Toward a better understanding of the bioavailability, physiology, and toxicity of silver in fish: Implications for water quality criteria
Agricultural residues are abundantly available in energy deficient developing countries. Many of the agricultural residues are considered as waste, and their energy potential has not been realized in energy recovery schemes. Coutilization of agricultural residues in existing coal fired power plants can help in producing clean energy, disposing of waste, and increasing the income of the rural population. Sheameal, cotton stalk, sugar cane bagasse, and wood chips were cofired with coal in 5, 10, and 15% thermal fractions in a 20 kW down-fired combustor. The combustion behavior of the blends of biomass-coal was examined. It was found that agricultural residues can be used as a potential substitute fuel and can help...
