Pollution-induced community tolerance (PICT) has been developed further and used in a number of situations (Blank 2002, Grant 2002, Boivin et al. 2002). 

Describe the concept of pollution-induced community tolerance (PICT) ... 

A variety of ecological parameters were determined (Table 9.4). Many parameters differed from the reference sample of field A (like the pollution-induced community tolerance (PICT) results) and showed an increase compared with the reference field, but this can be attributed at least partly to increased organic carbon... 

An interesting assay has been developed that uses communities of naturally occurring algae. The assay is based on the concept of pollution-induced community tolerance (PICT) (Blanck et al. 1988) whereby exposure to a toxicant results in the elimination of sensitive species and the dominance of tolerant ones quantification is achieved by using short-term assays for the inhibition of photosynthesis under laboratory conditions (Blanck and Wangberg 1988). One of the attractive features of the system is that it can be used in widely different situations ranging from microcosms and mesocosms to natural ecosystems.
