Aquatic toxicity of glyphosate-based formulations: comparison between different organisms and the effects of environmental factors.
Glyphosate-based herbicides (e.g. Roundup) are extensively used in the aquatic environment, but there is a paucity of data on the toxicity of the formulated products and the influences by… Expand
Variations in the chemical properties of landfill leachate
Landfill leachates were collected and their chemical properties analyzed once every two months over a ten-month period from the Gin Drinkers' Bay (GDB) and Junk Bay (JB) landfills. The contents of… Expand
Adsorption and degradation of five selected antibiotics in agricultural soil.
Large quantities of antibiotics are being added to agricultural fields worldwide through the application of wastewater, manures and biosolids, resulting in antibiotic contamination and elevated… Expand

Wastewater is increasingly being used to irrigate agricultural land in many countries around the world. However, limited research has examined the occurrence of antibiotics in soil irrigated with… Expand
Comparative Toxicity of Glyphosate-Based Herbicides: Aqueous and Sediment Porewater Exposures
AbstractGlyphosate-based herbicides are widely used for aquatic weed control. However, their aquatic toxicity data, especially those on sediment, are relatively scarce. In this study, the water-only… Expand
Heavy Metal Concentrations in Marine Fishes Collected from Fish Culture Sites in Hong Kong
The levels of six heavy metals (Cd, Cr, Cu, Ni, Pb, and Zn) in different tissues of three species of cultured marine fishes (Epinephelus areolatus, Lutjanus russelli, and Sparus sarba) collected from… Expand
Phytotoxicity of veterinary antibiotics to seed germination and root elongation of crops.
Large quantities of veterinary antibiotics (VAs) are being used worldwide in agricultural fields through wastewater irrigation and manure application. They cause damages to the ecosystem when… Expand
Ammonia stripping as a pretreatment for landfill leachate
The effectiveness of ammonia stripping at different air flow rates (0, 1 and 5 L min−1) and lime dosages (0 and 10 000 mg L−1 calcium hydroxide) was investigated in aeration tanks in a laboratory as… Expand

We propose a counting-based shape descriptor that captures global and local shape information independently so that they can be examined individually during classification. Expand
Effects of leachate recirculation on biogas production from landfill co-disposal of municipal solid waste, sewage sludge and marine sediment.
Leachate recirculation is an emerging technology associated with the management of landfill. The impact of leachate recirculation on the co-disposal of three major wastes (municipal solid waste,… Expand
