343:. The latter technique gives only an instantaneous concentration of the pollutant as the specific time of sampling. Passive samplers, depending on their mode of use, can give either the TWA or equilibrium concentration of the pollutant over the deployment period. The measurement of TWA concentrations can give a better indication of the long-term environmental conditions and enables improved risk assessment. Chemcatcher can be used to monitor both polar and non-polar compounds.

Most monitoring programmes involve the periodic collection of low volume spot samples (bottle or grab) of water, which is challenging, particularly where levels fluctuate over time and when chemicals are only present at trace, yet toxicologically relevant concentrations. Chemcatcher is used to
