“…The SPMDs were processed according to established procedures including dialytic recovery of the sequestered analytes, enrichment/fractionation using size exclusion chromatography, and fractionation using adsorption chromatography (Alvarez et al, 2008(Alvarez et al, , 2012Huckins et al, 2006). Detailed methodology was described by Alvarez et al (2014-in this issue).…”

Suitable test substances for proof of concept regarding infochemical effects in surface waters

Background: Infochemical effects have been defined as the manipulation of the odour perception of organisms by anthropogenic substances which may result in ecologically relevant behavioural disorder. However, the environmental relevance of infochemical effects has not yet been confirmed by experimental observations. This project aims to test for infochemical effects on chemical communication in water bodies with systematic experimental investigations. The first crucial step is to select suitable test substances. Repellents (PT 19 biocides) and odourants may be assumed to affect the response of aquatic populations and communities. These mostly polar and stable compounds may disturb chemical communication between organisms and may cause organismic effects like drift (downstream dislocation of e.g. crustacean and insect larvae in streams). Repellents enter surface waters mainly indirectly via wastewater discharges from sewage treatment plants or directly by being washed off from the skin and clothes of bathers. Results: In this literature study, suitable chemicals were selected for confirmatory assessments of suspected infochemical effects by laboratory tests in a subsequent second part of the project. The use pattern and physicochemical properties of the substances selected, in combination with their limited biological degradability, indicate potential aquatic relevance with possible chronic impact caused by disturbed communication. After due consideration of advantages and limitations, three PT 19 repellents appear suitable test compounds for proof of concept in the subsequent experimental part of the project:

A number of POCIS studies are also coupled to bioassays, evaluating endocrine-disruptive potential or dioxine-like activities (Jeffries et al 2011;Tapie et al 2011;Alvarez et al 2012;Jarosova et al 2012;Alvarez et al 2013;Jalova et al 2013;Creusot et al 2014).…”

Passive sampling is a rapidly developing technology, which is widely used for the monitoring of pollutants in different environments. Passive sampling offers significant advantages over traditional grab sampling. In the present review, the authors summarize the current literature on the methods of passive sampling used in the environmental monitoring of polar or semi-polar compounds in aqueous matrices. Methods of calibrating, design and deployment of samplers are also discussed. A major focus of this review is the use of polar organic compound integrative samplers (POCIS) and their use in sampling and monitoring of pharmaceuticals and personal care products (PCPs) in both equilibrium and non-equilibrium conditions.
