A Bed Sediment Sampler for Precise Depth Profiling of Contaminant Concentrations in Aquatic Environments

Abstract

AbstractA bed sediment and detritus sampler has been developed for use in aquatic environments, such as in canals, rivers or lakes, for determining precise depth profiles of contaminants. The device is superior to currently available commercial push‐tube and piston samplers in its simplicity, ease of use and its ability to retrieve and extrude sample cores. The sampler has been used with success during the past 12 mo to determine a profile of bed sediment Se concentrations within an earth‐lined canal, alternatively used for conveyance of agricultural drainage and wetland water supply.
