Comparing the Passive and Active Sampling Devices with Biomonitoring of Pollutants in Langstone and Portsmouth Harbour, UK

Overview of the Chemcatcher® for the passive sampling of various pollutants in aquatic environments Part A: Principles, calibration, preparation and analysis of the sampler

“…Acetone was afterward allowed to evaporate which resulted in a disk loaded with 450 ml of n-octanol. For El-Shenawy et al [72,73], the drying step under vacuum was replaced by the use of a dry tissue in order to remove excess water while avoiding complete drying of the disk.…”

Overview of the Chemcatcher® for the passive sampling of various pollutants in aquatic environments Part B: Field handling and environmental applications for the monitoring of pollutants and their biological effects

“…No different field exposure position was mentioned in the publications studied for the present review. Some precautions should be taken when submerging the device in order to avoid trapped air bubbles on the surface of the sampler [6][7][8]. To protect the sampler and facilitate its handling in the field, Chemcatchers s can be deployed in cages made of stainless-steel (see for instance [9]- [12]) or in nylon-mesh baskets [13].…”

“…Exposure depth in the water column, which depends on site and deployment constraints, is mentioned by seven of the authors ( [9,10,18] and following ones). Depths were between 15 cm [7,12,19] and 1.5 m [20] below the surface. Chemcatcher s deployment periods generally ranged from 7 to 30 days, with 14 days being quite common.…”

Comparison of marine sampling methods for organic contaminants: Passive samplers, water extractions, and live oyster deployment

“…Oysters were deployed in the estuary for as long as the passive samplers. This would allow for a long term averaging in the estuary, comparable to the samplers and other studies (Cernoch et al, 2011;Dalton et al, 2014;El-Shenawy et al, 2010;Fox et al, 2010;Mi ege et al, 2012;Thromatou et al, 2011) without the constraints of small volume laboratory incubations on oyster health. Upon recovery, the passive samplers were immediately placed into jars containing 250 mL of methanol, while oysters were placed in zip lock bags and placed on ice for transportation to the laboratory.…”
