Summary: In order to address the question: Does bioaccumulation of pollutants by aquatic plants increase (or decrease) by sediment bioturbation under benthic invertebrate activity? Oligochetes tubificidae‚ famous invertebrate worms‚ was used as an active ecological engineer and biotubartion source. Biological sediment reworking generated by this invertebrates activity will be quantified using luminophores‚ inert particulate and dissolved tracers. One aquatic plant species‚ Typha latifolia was set

| Distillation is defined as: `Distillation is based on the fact that the vapor of a boiling mixture will be richer in the components that have lower boiling points.Therefore‚ when this vapor is cooled and condensed‚ the condensate will contain more volatile components. At the same time‚ the original mixture will contain more of the less volatile material. Distillation columns are designed to achieve this separation efficiently.Although many people have a fair idea what “distillation” means‚ the
