Macrofauna-induced bioturbation of soil is dominated by earthworms, among other invertebrates, in most grassland and forest soil. First observed by Darwin, bioturbation drives particle mixing in the upper surface layers, leading to beneficial results

The processes by which oil-material appears suspended in the water column or becomes deposited on the sea floor is conventionally attributed to its attachment to marine solid particles. Sin...

In this study we have investigated the effect of surfactant, sodium dodecyl sulfate (SDS), on the dynamics of a single crude oil droplet, rising in a quiescent water column. Experiments were conducted in a tank, in which an oil droplet was released i

Photocatalytic pavements are a promising solution for air pollution remediation from automobile sources; however, understanding their efficacy in real-world environments remains a challenge. This study proposed an environmental model based on reactio

A thin film coats impervious urban surfaces that can act as a source or sink of organic pollutants to the greater environment. We review recent developments in the understanding of film and film-associated pollutant behavior and incorporate them into

Among the discoveries of the Deepwater Horizon blowout was the so-called "sub-surface plume"; herein termed the "oil-trapping layer". Hydrocarbons were found positioned at ~1100-1300m with thickness ~100-150m and moving horizontally to the SW in a ve

The various complex forms of transport as well as many other fate processes ongoing in the marine water column require research for the understanding and prediction of impacts of deepwater releases on the marine ecosystem. Such research is useful for

The fate of persistent organic pollutants (POPs) is a worldwide concern that resulted in the Stockholm Convention of 2001. Current global transport models are primarily evaluative and therefore limited in predicting realistic concentrations of POPs.

Sediment particles can be displaced from the bed to the water column by both natural processes and human activities. Navigational and environmental dredging operations are known to generate particularly high concentrations of suspended sediment and h
