Volatile organic compound diffusion and sorption coefficients for a needle-punched GCL
Craig B. Lake,R. K. Rowe +1 more
TL;DR: In this paper, a test apparatus designed to examine volatile organic compound (VOC) diffusion through geosynthetic clay liners (GCLs) is described, together with procedures for evaluating the relevant diffusion and sorption parameters.

Effect of pyrolysis temperatures on freely dissolved polycyclic aromatic hydrocarbon (PAH) concentrations in sewage sludge-derived biochars.
Anna Zielińska,Patryk Oleszczuk +1 more
TL;DR: As regards agricultural use of biochar, the lower contents of Cfree PAHs in the biochars compared to the sewage sludges makes biochar a safer material than sewage sludge in terms of PAH contents.

Methane and oxygen dynamics in a shallow floodplain lake: the significance of periodic stratification
TL;DR: In this paper, temperature, dissolved oxygen and dissolved methane profiles were measured during autumn and summer, in a shallow floodplain lake in south-eastern Australia to determine the effects of water column stability on methane and oxygen dynamics.

Bottom trawling resuspends sediment and releases bioavailable contaminants in a polluted fjord
Clare Bradshaw,Ingrid Tjensvoll,Mattias Sköld,Ian Allan,Jarle Molvær,Jan Magnusson,Kristoffer Næs,Hans C. Nilsson +7 more
TL;DR: This field study in a trawled contaminated Norwegian fjord showed that a single 1.8 km long trawl pass created a 3-5 million m(3) sediment plume containing around 9 t contaminated sediment; ie.
