In order to predict the fate of contaminant transport in plants, experiments were conducted and simple models were used to simulate the processes. Diffusion experiments were carried out to estimate contaminant diffusivity within plant roots, while adsorption experiments were used to investigate the adsorption of contaminant in plant stems. We found that plants can enhance the removal of trichlo...

A class of compounds known as polybrominated diphenyl ethers (PBDEs)-flame-retardant additives used in high-impact plastics, foams, and textiles-has recently sparked concerns among environmental health scientists. PBDEs are part of a superfamily of related toxic compounds known as persistent organic pollutants (POPs). Limited evidence suggests they may be associated with health effects includin...

The treatment of metal-contaminated sediment generated in environmental dredging projects often requires both reduction and remediation, the electric field has good application prospects integration remediation. In this study, based on electro-osmosis, vacuum, vacuum electro-osmosis methods, a detachable test system was made. Experiments three methods were carried out independently remediation ...

fluid properties with constant improvement in efficiency have been noticeable as important criteria in drilling operation. the main drilling fluid properties highly depend on utilization of new polymers with high efficiency in drilling fluid composition. in this paper, the performance of a new polymer, called partially hydrolyzed polyacrylamide polymer (phpa), is studied which has recently ente...
