...The percentage compositions of LMW and HMW PAHs in the random site samples of this study were similar to site-specific observations in both Minnesota Slip and Slip C in the Duluth Harbor (Crane et al., 2002b)....
[...]
...These ranges were analogous to the mean PEC-Q ranges used by Ingersoll et al. (2001) and Crane et al. (2000, 2002a) to evaluate the predictive ability of freshwater sediment quality guidelines and SQTs....
[...]
...In this evaluation, mean PEC-Qs were calculated using the methods that were recommended by Ingersoll et al. (2001) and outlined in Crane et al. (2000, 2002a)....
[...]
...The chronic 28 to 42 d H. azteca toxicity test is more sensitive than either the 10 d amphipod or midge tests (Ingersoll et al., 2001), and its use would reduce the potential for false negatives at low mean PEC-Qs....

...The PECs, developed by Ingersoll et al. (2001), have been adopted as an informal tool to evaluate sediment chemical data in relation to possible adverse effects on aquatic biota....
[...]
...A PEC quotient (PECQ) was calculated for each chemical in each sample by dividing the concentration of a chemical by the PEC for that chemical (Ingersoll et al. 2001)....

...(PECQ) was calculated for each chemical in each sample by dividing the concentration of a chemical by the PEC for that chemical (Ingersoll et al. 2001)....
[...]
...The mean PECQs (mPECQ) were then calculated for each sample by summing the individual quotient for each chemical and dividing this sum by the number of reliable PECs evaluated in Table 2 (Ingersoll et al. 2001)....

...According to these results, these elements could potentially have harmful effects on a large proportion of the benthic community and may be transferred to fish species (Ingersoll et al., 2001)....

...…concentrations because previous studies have demonstrated that normalization of SQGs for PAHs or PCBs to total organic carbon (Barrick et al. 1988, Long et al. 1995, Ingersoll et al. 1996) or normalization of metals to acidvolatile sulfides (Long et al. 1998b) did not improve the predictions of…...

...Similarly, Long et al. (1998a) reported a 56 to 71% incidence of toxicity at mean quotients of >1....

...The TECs were calculated by determining the geometric mean of the SQGs that were included in this category (MacDonald et al. 2000a)....

...…results of these three previous investigations demonstrated that the consensus-based SQGs provide a unifying synthesis of the existing guidelines, reflect causal rather than correlative effects, and account for the effects of contaminant mixtures in sediment (Swartz 1999, MacDonald et al. 2000a,b)....

...A second paper developed and evaluated consensus-based SQGs for total polychlorinated biphenyls (PCBs) to address a similar mixture paradox for that group of contaminants (MacDonald et al. 2000b)....

...The consensus-based PECs listed in Table 1 were critically evaluated by MacDonald et al. (2000a) to determine if they would provide effective tools for assessing sediment quality conditions in freshwater ecosystems....

...Therefore, the differences in this “MPP approach” from the approach used by MacDonald et al. (2000a) are: (1) an average quotient for metals was used instead of the individual quotients for metals and (2) sum DDE was not used in the calculation....

...Alternatively, Long et al. (1998a) classified sediments in a marine amphipod database as either marginally toxic (significantly reduced relative to the control) or as highly toxic (significantly reduced relative to the control with a reduction greater than a minimum significant difference; MSD)....
[...]
...Long et al. (1998a) and Field et al. (1999) reported reduced variability in the relationship between toxicity and sediment contamination when toxicity was evaluated using a standardized approach....

...The incidence of toxicity was only 12% at mean quotients of <0.1 (quotients calculated using either marine effect range median (ERM) or probable effect level (PEL) guidelines; Long et al. 1998a)....
[...]
...Long et al. (1998a) also observed an elevated incidence of toxicity with marine amphipods at low mean quotients....
[...]
...For this reason, the evaluation of the predictive ability of the SQGs in the present study was conducted to determine the incidence of effects above and below various mean PEC quotients (mean quotients of 0.1, 0.5, 1.0, and 5.0; Ingersoll et al. 1998, Long et al. 1998a, Fairey et al. 2000)....

The MSD was established by Long et al. (1998a) using a power analysis of data from 10-day marine amphipod tests (Thursby et al....
