Chapter 8 Tool for monitoring hydrophilic contaminants in water: polar organic chemical integrative sampler (POCIS)

Analysis of drugs of abuse in wastewater from two Canadian cities

“…A possible explanation for the low compatibility of the sorbent and POCIS configuration used with heroin, acetylcodeine and acetylmorphine could be due to their acetylated structures, giving a high polarity and an affinity for water over the sorbent. Previous work has also indicated that extremely polar compounds don't sorb to POCIS sequestration media (Alvarez et al, 2007). Mass balance calculations were conducted to see if the amount of the target analytes adsorbed to the POCIS sorbent accounted for the amount of these compounds lost from water over the course of the static experiment.…”

The occurrence of illicit and therapeutic pharmaceuticals in wastewater effluent and surface waters in Nebraska

“…Its ease of use and apparent resistance to biofouling make it particu-larly attractive for determining time-weighted average (TWA) concentrations of organic compounds in water . POCIS have been used previously for both qualitative and quantitative evaluation of pharmaceuticals, pesticides and hormones in surface waters (Alvarez et al, , 2007Arditsoglou and Voutsa, 2008;Harman et al, 2008;Jones-Lepp et al, 2004;MacLeod et al, 2007;Zhang et al, 2008).…”

Passive Sampling Technologies for the Monitoring of Organic and Inorganic Contaminants in Seawater

“…The results showed that the French Mediterranean coastal waters were contaminated with a large range of emerging contaminants, detected at low concentrations during the summer season. Alvarez et al (2013) used POCIS, PE and SPME samplers to sample a diverse set of chemicals in the coastal waters of San Francisco Bay and the Southern California Bight. Seventy-one chemicals (including fragrances, phosphate flame retardants, pharmaceuticals, PAHs, PCBs, PBDEs and pesticides) were measured in at least 50 % of the sites.…”
