Identification and confirmation of ammonia toxicity in contaminated sediments using a modified toxicity identification evaluation approach

Twelve particle-bound polycyclic aromatic hydrocarbons (PAHs) were measured in the first flush regime of road runoff during nine events in Winterthur in Switzerland. The total PAH contents ranged from 17 to 62 μg/g. The PAH patterns measured at different time intervals during the first flush periods were very similar within each event irrespective of variation in suspended solids (SS) concentration within the first flush regime. However, the PAH patterns were different from event to event. This indicates that the environment plays an important role in PAH accumulation in SS. A toxicity identification evaluation approach using a toxicity equivalency factor (TEF) was applied to compare toxicities in the different events. The TEFs were found to be between 8 and 33 μg TEQ g−1 (TEQ: toxic equivalent concentration). In some cases, two events having similar total PAH contents showed two fold toxicity differences.

Toxicity Identification

The case study for evaluating the EPA Toxicity Identification Evaluation protocol was a textile dye manufacturing plant that suspected chloride as the major source of toxicity. Phase I of the protocol, together with some additional experiments, was successful in showing that one-third to one-half of the toxicity was due to chloride and the rest was due to nonpolar organic compounds. From 41 to 78 organic chemicals were found in toxic fractions using the EPA Phase II test procedures; these included dyes, dye intermediates, process chemicals such as surfactants and possibly metabolic by-products of waste treatment. A major component of Surfynol, a widely used surfactant, was present in concentrations much higher than any other chemical in the toxic fractions of all three samples analyzed. However, the concentration was still considerably less than the LC50 (mg/L) and thus could not explain whole effluent toxicity. Instead, more than one organic chemical may be involved.
