“…The crucial feature of the PICT concept is that community tolerance is determined by the means of short-term toxicity tests: comparison of the obtained EC 50 value with that of an unexposed (reference) community clarifies whether or not the toxicant has affected the community (Blanck and Dahl 1996). Most studies have focused on the impact of toxicants (metals, pesticides, etc.)…”

“…light conditions, nutrient concentrations and grazing pressure) than the mortality/immobility endpoint. In addition, populations and communities of algae, which are characterized by an overall short generation time of the organisms, may develop tolerance within a relatively short period of time (Kasai and Hanazato 1995;Blanck and Dahl 1996;Blanck 2002).…”

“…Cette approche a été appliquée sur des communautés algales et microbiennes aquatiques (phytoplancton, périphyton, epipsammon : Admiraal et al 1999 ;Dahl 1996 ;Dahl & Blanck 1996b). Dans le principe, elle pourrait s'appliquer à n'importe quel type de communauté -elle a été utilisée pour mettre en évidence les impacts du cuivre sur des communautés de nematodes aquatiques (Millward & Grant 1995) -à partir du moment où les questions d'échantillonnage sont résolues et les moyens d'évaluer la composition taxonomique et la tolérance de la communauté complète sont efficaces.…”

“…Elles concernent surtout les métaux ou leurs dérivés : TBT (Blanck & Dahl 1996, cuivre (Gustavson et al 1999), arsenic (Wangberg 1995, Knauer et al 2000, zinc (Admiraal et al 1999), la plupart concernant des pollutions non diffuses et bien identifiées. Une étude in situ a permis d'évaluer la zone d'influence d'une source ponctuelle de pollution aérienne par l'arseniate, sur les communautés phytoplanctoniques de lacs situés autour de cette source de pollution (Wangberg 1995).…”
