Separating microplastics from marine and freshwater sediments is challenging, but
necessary to determine their distribution, mass, and ecological impacts in benthic
environments. Density separation is commonly used to extract microplastics from
sediments by using heavy salt solutions, such as zinc chloride and sodium iodide.
However, current devices/apparatus used for density separation, including glass
beakers, funnels, upside-down funnel-shaped separators with a shut-off valve, etc.,
possess various shortcomings in terms of recovery rate, time consumption, and/or
usability. In evaluating existing microplastic extraction methods using density
separation, we identified the need for a device that allows rapid, simple, and efficient
extraction of microplastics from a range of sediment types. We have developed a
small glass separator, without a valve, taking a hint from an Utermöhl chamber.
This new device is easy to clean and portable, yet enables rapid separation of
micropla.....
