The primary fish gill cell culture system (FIGCS) is anin vitrotechnique which has the potential to replace animals in whole effluent toxicity tests. In the current study FIGCS were transported into the field and exposed to filtered (0.2 μm) river water for 24 h from 4 sites, on 2 different sampling dates. Sites 1 and 2 are situated in an urban catchment (River Wandle, London, UK) with site 1 downstream of a sewage treatment work; site 3 is located in a suburban park (River Cray, Kent, UK), and site 4 is more rural (River Darent, Kent, UK). The change in transepithelial electrical resistance (TER), the expression of the metal responsive genes metallothionein A (mta) and B (mtb), cytochrome P450 1A1 (cyp1a1) and 3A27 (cyp3a27), involved in phase 1 metabolism, were assessed following exposure to sample water for 24 h. TER was comparable between FIGCS exposed to 0.2 μm filtered river water and those exposed to synthetic moderately soft water for 24 h. During the first sampling time, there was an increase inmta,cyp1a1andcyp3a27gene expression in epithelium exposed to water from sites 1 and 2, and during the second sampling period an increase incyp3a27gene expression at sites 1 and 4. Urban river water is a complex mixture of contaminants (e.g., metals, pesticides, pharmaceuticals and polyaromatic hydrocarbons) and the increase in the expression of genes encodingmta,cyp1a1andcyp3a27in FIGCS is indicative of the presence of biologically active pollutants.
