Ranking scheme and battery of tests approach

A slightly revised format to award points for specific data values in order to rank the sampled waters and sediments is presented in Table 4.3, which shows the ranking scheme and battery of tests approach used by Dutka et al. (1991). Surface water samples were collected at seven sites (three per site) for eight toxicant
