Performance of passive samplers for monitoring estuarine water column concentrations: 2. Emerging contaminants

Evaluation of the Chemcatcher and DGT passive samplers for monitoring metals with highly fluctuating water concentrations.

Passive sampling devices accumulate chemicals continuously from water and can provide time weighted average (TWA) concentrations of pollutants over the exposure period. Hence, they offer a number of advantages over other conventional monitoring techniques such as spot or grab sampling. The diffusive gradient in thin film (DGT) and the Chemcatcher passive samplers can be used to provide TWA conc...

Short-term exposure testing of six different passive samplers for the monitoring of hydrophobic contaminants in water.

Passive sampling devices are increasingly relied upon for monitoring non-polar organic contaminants in water. While many types of devices are available they have seldom been evaluated alongside each other. We tested six passive sampling devices namely: Chemcatcher, two modified versions of the membrane enclosed sorptive coating (MESCO I (m) and MESCO II), silicone rod and strip and semipermeabl...

Guidelines for passive sampling of hydrophobic contaminants in water using silicone rubber samplers

Application of passive sampling for measuring dissolved concentrations of organic contaminants in the water column at three marine superfund sites.

Currently, there is an effort under way to encourage remedial project managers at contaminated sites to use passive sampling to collect freely dissolved concentrations (Cfree ) of hydrophobic organic contaminants to improve site assessments. The objective of the present study was to evaluate the use of passive sampling for measuring water column Cfree for several hydrophobic organic contaminant...

Monitoring of Aquatic Environments Using Passive Samplers

A review is given on the development of passive samplers for aquatic environments. Passive samplers that are simple and easy to use and with minimal consumption of organic solvents to desorb the analytes from the trapping media are focused. New developments in quality assurance procedures are highlighted.
