Ceramic Toximeter as a Passive Sampler for Dioxin-Contaminated Water AnalysisUsing the CALUX Bioassay.

Passive sampling is a new trend in environmental monitoring and analysis. Several Passive samplers are being developed to overcome the drawbacks of the conventional snapshot sampling approach. The idea relies on the uptake of contaminants into an appropriate sampling device along a diffusion gradient without using pumps or bailers. Once the diffusion gradient between the medium and the sampler's interior is steady, the contaminants can be continuously sampled over an extended period allowing for the calculation of a time-weighted average (TWA) concentration.In this research, we aim to develop and evaluate the ceramic toximeter as a passive sampler for monitoring dioxin-contaminated water.
