“…[51][52][53] The hardness values obtained for Leça river were normal for surface water and, therefore, the metals Fe, Hg and As contributed to global toxic eff ect. Nevertheless, Microtox® test is especially sensitive to several metals, such as Hg, Pb, Zn and Cu [54,55]; the toxicity of heavy metals is highly influenced by matrix eff ects, conditions and concentration, [56,57] The faecal coliforms in Leça river presented extremely high concentrations showing positive correlation with the V. fischeri toxic response probably due to competition between the bacteria, both Gram-negative, heterotrophic and facultative anaerobes. This competition might be for oxygen, which would influence the luminescence produced once its mechanism is intrinsically connected to the respiratory metabolism.…”

The ecotoxicological response of the living organisms in an aquatic system depends on the physical, chemical and bacteriological variables, as well as the interactions between them. An important challenge to scientists is to understand the interaction and behaviour of factors involved in a multidimensional process such as the ecotoxicological response. With this aim, multiple linear regression (MLR) and principal component regression were applied to the ecotoxicity bioassay response of Chlorella vulgaris and Vibrio fischeri in water collected at seven sites of Leça river during five monitoring campaigns (February, May, June, August and September of 2006). The river water characterization included the analysis of 22 physicochemical and 3 microbiological parameters. The model that best fitted the data was MLR, which shows: (i) a negative correlation with dissolved organic carbon, zinc and manganese, and a positive one with turbidity and arsenic, regarding C. vulgaris toxic response; (ii) a negative correlation with conductivity and turbidity and a positive one with phosphorus, hardness, iron, mercury, arsenic and faecal coliforms, concerning V. fischeri toxic response. This integrated assessment may allow the evaluation of the eff ect of future pollution abatement measures over the water quality of Leça River.

Monitoring of the ecotoxicological hazard potential by polar organic micropollutants in sewage treatment plants and surface waters using a mode-of-action based test battery

We propose and evaluate a mode-of-action based test battery of low-complexity and in-vitro bioassays that can be used as a routine monitoring tool for sewage treatment efficiency and water quality assessment. The test battery comprises five bioassays covering five different modes of toxic action. The bioluminescence inhibition test with Vibrio fischeri and a growth rate inhibition test with the green algae Pseudokirchneriella subcapitata are measures of non-specific integrative effects. A second endpoint in the algae test, the specific inhibition of the efficiency of photosynthesis, gives an account of the presence of herbicides. An enzymatic assay covers an important aspect of insecticidal activity, the inhibition of the acetylcholine esterase activity. Estrogenic effects are assessed with the yeast estrogen screen (YES) and genotoxicity with the umuC test. Three field studies, each lasting six to seven consecutive days, were undertaken at a sewage treatment plant (STP) in Switzerland. Samples were collected in summer and late autumn, under dry and rainy conditions. None of the bioassays gave positive results with raw water in whole effluent toxicity testing. Therefore, water samples from various sites during wastewater treatment and from surface water were enriched with solid-phase extraction. The focus was on non-volatile compounds of average to moderate hydrophobicity, a range that includes most pesticides, biocides and pharmaceuticals. Various polar solid phases were evaluated for their extraction efficiency, disturbance by matrix components and overall performance. We finally selected a mixture of a polymeric sorbent and a C18-sorbent, Lichrolut EN and RP-18 or, alternatively, Empore SDB-RPS disks. All bioassays gave clear and robust responses with the SPE extracts. With the bioassay data the treatment efficiency of the STP can be assessed with respect to different modes of toxic action and accordingly different groups of micropollutants. Furthermore, the data allowed for a comparison between the effluent and the receiving river. In all bioassays the primary effluent had a strong effect and this effect was reduced after passing the STP. Treatment efficiency was high (typically over 90%) but varied from bioassay to bioassay, which is expected because each bioassay detects different types of micropollutants and therefore we cannot expect a common answer.

Tanning wastewater was subjected to different unit operations to select the best treatment sequences. Textile membrane filtration (TMF), microfiltration (MF), and ultrafiltration (UF) were complemented by screening, flocculation or flotation operations. The general chemical characterization determined that the wastewater had a high organic load. The ecotoxicological study classified the wastewater as highly ecotoxic. The sequence of screening-TMF-UF was found to be the optimal treatment for wastewaters of the first and second soaking stages, while the sequence of screening-TMF-flotation-UF proved to be adequate for the liming wastewater concerning productivity and water quality. Larger pore sizes MF membrane or higher molecular weight cut off (MWCO) UF membranes with higher permeability to pure water showed lower permeation fluxes for tanning wastewater. After membrane treatments, a decrease in the ecotoxicity was measured. The use of membrane treatment technology showed to be promising in removing organic pollutants and allowing the reuse of water and chemicals in the process.Résumé : Les eaux résiduelles de l'industrie de tannerie ont été soumises à différentes opérations de façon choisir les meilleures séquences de traitement possibles. La filtration par des membranes textiles, la microfiltration et l'ultrafiltration ont été complémentées par des opérations de tamisage, de floculation ou de flottation. La caractérisation chimique générale a montré un effluent avec une charge organique élevée. Aussi, la caractérisation écotoxicologique autorise une classification hautement écotoxique. Du point de vue du traitement, la séquence tamisage/ filtration par membranes textiles / ultrafiltration s'est avérée être le traitement optimal pour les eaux résiduelles des premiers et seconds stages de trempage, tandis que la séquence tamisage/ filtration par membranes textiles / flottation / ultrafiltration a été la plus adéquate pour l'eau résiduelle de chaulage en raison de la productivité et la qualité de l'eau. Pour ces eaux résiduelles de tannerie, les plus basses valeurs des fluxs de perméabilité ont été obtenues avec des membranes de microfiltration de large porosité ou des membranes d'ultrafiltration avec un seuil de coupure supérieur, lesquelles présentent une perméabilité élevée pour l'eau pure. Après les traitements par membranes des eaux résiduelles, on a mesuré une diminution de l'écotoxicité. L'utilisation de la technologie de traitement par membranes pour le retrait des polluants organiques s'est révélée intéressante en permettant la réutilisation de l'eau et des produits chimiques dans le processus.
