“…This organic compound was below the detection limit in the sediment samples from the Taquari River in previous studies and during this study (data not shown), but present in internal wetlands of the contaminated area [FEPAM, ]. PCP was also detected in the samples from the stream investigated (0.664 mg/kg) [Costa et al, ] and in dust samples from the residential area (0.49 mg/kg) in the region studied [Coronas et al, ]. Both samples had higher values than those established by the soil contamination prevention law in Brazil (0.16 mg/kg) [Brasil, ].…”

“…TA97a being described in the literature as most sensitive to heavy metals [Pagano and Zeiger, 1992] and PAHs; TA100, which detects mutagenic by base pair substitution [Maron and Ames, 1983].

“…The Salmonella strains have been considered in the literature as sensitive to the presence of PAHs in the environment [Chen and White, 2004;Pohren et al, 2012;Coronas et al, 2013]. These compounds are considered mutagenic and require the presence of metabolic activation to show their effect [Watanabe et al, 2005[Watanabe et al, , 2008Courty et al, 2008].…”

“…While operating, it used the following compounds as wood preservatives: pentachlorophenol (PCP) that can generate dioxins; creosote, formed by polycyclic aromatic hydrocarbons (PAHs); and chrome copper arsenate (CCA), with high toxic, genotoxic and carcinogenic potentials [Appel et al, ]. Among the studies already performed in this area, PAHs, PCP, dioxins and heavy metals were detected in soil and house dust samples associated with the presence of mutagenic and cytotoxic activity measured by the Salmonella /microsome assay [FEPAM, ; Pohren et al, ; Coronas et al, ]. It was also possible to define the routes of these contaminants from the soil to the main river, using the same chemical markers (chemical groups of compounds present in the wood preservatives) detected in this drained material in association with the Salmonella /microsome assay [Costa et al, ].…”

Soil contamination enters aquatic ecosystems affecting sediment quality. The region studied is the Taquari River, Brazil, close to a site contaminated by wood preservatives, with a runoff route into the river. The first stage of the remediation process (In this article, the terms intervention and remediation have been used with slightly different meanings. We consider intervention to be the first phase of the remediation process, which aims to remove active sources) was an intervention to remove the main active sources. The Salmonella/microsome assay and polycyclic aromatic hydrocarbons (PAHs) were used to assess sediment quality in organic extracts during different intervention phases. The strains used were TA98, TA97a, and TA100 with and without S9mix (±S9). The results indicated the presence of pro-mutagens at site Ta010 (closest to the contaminated site) in all samplings, and the highest result occurred before intervention for TA100 + S9 (1,672 ± 215.9 rev/g). These values decreased during (83 ± 23.6 rev/g) and after this process (403 ± 105.9 rev/g), although the PAHs concentrations increased. Samples from this site presented PAHs with a carcinogenic potential during the assessed periods. After intervention, Ta006 (4 km downstream from Ta010) showed the most significant mutagenesis for TA100 + S9 (764 ± 230.2 rev/g) and, although the total PAHs values were lower, the species considered carcinogenic had higher concentrations. Mutagenesis predicted values of PAHs confirmed that carcinogenic species were predominantly detected by TA100, and the other PAHs by TA97a strains. Marked contaminant release to the river was observed, mainly in Ta010 at different periods. Mutagenicity and PAHs values in an internal stream, upstream from Ta010, showed a dispersion route of these agents. Thus, contamination in Ta010 and possible contribution to Ta006, after intervention, provides a warning regarding environmental quality in the region. Environ. Mol.

Among the studies already performed in this area, it was possible to indicate the presence of these compounds and PAHs were detected) detected, both in samples of soil inside the company, in domestic dust and atmospheric compartment (Coronas et al, 2013;Pohren et al, 2012).

The region studied on the Taquari River, is close to a site with soil contaminated by wood preservatives, where a route of contaminants into the river was identified. This site was submitted to the first stage of the intervention process excavating the soil to remove the main active sources. To assess sediment quality the PAHs concentrations were analyzed: before, during and after the process. The PAHs concentration was compared to the guide values adopted by CONAMA resolution 344/04, aiming to protect aquatic life. Four points on Taquari River were tested, upper (TA032), in front (TA010) and lower (TA006, TA004) the contaminated site. Besides these, the Stream that is considered a source of contamination for TA010 was evaluated in the last step. The results indicated values between ISQG (Interim Sediment Quality Guidelines and PEL (Probable Effect Level) observed for eight PAHs. The PAHs values, probably carcinogenic to humans, were between ISQG and PEL in different samplings at TA010, more expressives during and after intervention. These values were also found at TA006 and TA004 during the same periods. The persistent contamination of the critical point TA010, even after intervention, is a warning regarding the environmental quality and aquatic life of this region.
