Passive samplers for chemical substance monitoring and associated toxicity assessment in water
The European legislation, and in particular the Water Framework Directive requires the development of cost efficient monitoring tools that can provide the required information for the assessment of water contamination. Passive sampling methods represent one of the novel tools that have a potential to be used in various regulatory monitoring programmes aimed at assessing the levels of chemical ...

Calibration of a passive, in situ, integrative sampler for monitoring of microbial biotoxins in aquatic environments
In this work, an integrative passive sampler based on a silicone membrane filled with a suspension of γ-Fe2O3 at pH 3.5 was developed. The novel device was calibrated for the measurement of microcystin concentrations in water. Laboratory calibration studies of the passive sampling devises under controlled conditions of temperature, water turbulence, and analyte concentration were conducted in ...

Application of passive sampling for measuring dissolved concentrations of organic contaminants in the water column at 3 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 ...

Low-Flow (Minimal Drawdown) Ground-Water Sampling Procedures
Untitled Document Background The Regional Superfund Ground Water Forum is a group of ground-water scientists, representing EPA's Regional Superfund Offices, organized to exchange information related to ground-water remediation at Superfund sites. One of the major concerns of the Forum is the sampling of ground water to support site assessment and remedial performance ...
