“…Available literature regarding the effects of sorbed LAS on Venice lagoon benthic organisms indicate that LAS concentrations in the investigated sediment core are at least 10‐fold lower than those causing adverse effects on marine organisms [41].…”

Abstract-The occurrence and behavior of the aromatic surfactants linear alkylbenzene sulphonates (LAS) and nonylphenol polyethoxylates (NPE) as well as their biotransformation products in the central lagoon of Venice, Italy, were investigated by monitoring deep-and shallow-water lagoon stations, two riverine sites, and one sea station. Additional samplings were conducted at the three inlets connecting the lagoon with the open sea under both ebb and low-tide conditions, and a radiometrically dated sediment core spanning the last century was examined. The spatial distributions of LAS, NPE, and their carboxylic metabolites sulphophenyl carboxylates and nonylphenol carboxylates, respectively, appeared to be rather homogeneous over the entire central lagoon. Remarkable seasonal differences were found, however, primarily because of the increased biodegradation at temperatures greater than 20ЊC. The estimated primary and ultimate biodegradations of LAS in the lagoon waters were approximately 90 and 72%, respectively. Analysis of the dated sediment core showed similar annual fluxes of both LAS and NPE (48 ng/cm 2 year), which were between previously reported values of polychlorinated biphenyls (4.7 ng/cm 2 year) and polycyclic aromatic hydrocarbons (167 ng/cm 2 year).

“…Studies with fishes showed a similar pattern and found responses in the animals exposed to low LAS concentrations (BARBIERI et al, 2000;BARBIERI et al, 2002). Marin et al (1994), in a study on the effects of LAS contaminated sediments on the mussel Mytilus galloprovincialis, observed a not significant increase in the respiratory rate of the exposed organism.

“…The LAS is nowadays widely spread in many different aquatic environments, where it has a significant pollutant potential. Since the 1970's decade, investigations on the toxic effects of the LAS have been conducted with aquatic organisms, as fish (SWEDMARK et al, 1971;BARBIERI et al, 2002), crustaceans (SWEDMARK et al, 1971;LEWIS and SUPRENANT, 1983;SINGH et al, 2002) and mollusks (SWEDMARK et al, 1971;MARIN et al, 1994;DA ROS et al, 1995;HANSEN et al, 1997), especially in Europe and North America.…”

The effects of the Linear Alkylbenzene Sulphonate (LAS) were evaluated on the mussel Perna perna, using physiological and genotoxic biomarkers. The Micronuclei (MN) assay was used to estimate effects at nuclear level, whereas the physiological effects were evaluated by measuring the oxygen consumption and ammonia excretion rates. Significant effects were observed for the MN assay and the ammonia excretion rate, even in low concentrations. The oxygen consumption was not affected in the tested concentrations. For MN and ammonia excretion, the animals exposed to intermediate concentrations were not affected, but responded to the higher concentrations, indicating the existence of compensatory mechanisms at physiological level. However, parallel to this study other authors indicate the presence of progressive effects at the cellular level, suggesting that the organisms are not capable to recover of such increasing effects. Additionally, the results show that the levels of LAS observed for Brazilian coastal waters may chronically affect the biota. Keywords: Ecotoxicology. Biomarkers. Detergent. Effect. Marine pollution. Mussel. RESUMOOs efeitos do Alquilbenzeno Sulfonato de Sódio Linear sobre o mexilhão Perna perna foram avaliados por meio do uso de biomarcadores genotóxicos e fisiológicos. O ensaio da taxa de micronúcleos (MN) foi conduzido para estimar o efeito ao nível nuclear, enquanto os efeitos fisiológicos foram avaliados através da medição da taxa de consumo de oxigênio e de excreção de amônia. Efeitos significativos foram observados para o ensaio do MN e para a taxa de excreção de amônia, mesmo em baixas concentrações. O consumo do oxigênio não foi afetado pelas HOLOS Environment, v.11 n.1, 2011 -P. 45 ISSN:1519 concentrações dos ensaios. Para MN e excreção de amônia, os animais expostos às concentrações intermediárias não foram afetados, mas responderam às maiores concentrações, sugerindo a existência de mecanismos compensatórios em nível fisiológico. Contudo, paralelamente ao presente estudo, outros autores demonstraram haver efeitos progressivos em nível celular, sugerindo que os organismos não conseguem se recuperar dos efeitos crescentes da exposição. Os resultados ainda mostram que níveis de LAS presentes na costa brasileira podem afetar cronicamente a biota. Palavras-chave: Ecotoxicologia. Biomarcadores. Detergente. Efeito. Poluição marinha.

“…Surfactants caused pooled in toxicity affecting the ecosystem and its inhabitants, the toxicity increasing down the trophic levels. The extent of surfactant toxicity is concentration dependant and it varies with season (Marcomini et al 2000 ), prevalence of anaerobic environment (Mungray and Kumar 2009 ), predominance of urban and industrial sewage outlets (Lara-Martin et al 2008 ), distance of sampling points from port of discharge (Gonzalez-Mazo et al 2002 ), occurrence of offshore oil spill or gas exploration, diurnal discharge of sewage (Kantin et al 1981 ), salinity (Lewis 1992 ), hardness of water (Oya et al 2008 ) and presence of adsorbents (Casellato and Negrisolo 1989 ;Marin et al 1994 ). The extend and mode of toxicity is also infl uenced by the chemistry of the pollutant surfactant, its alkyl chain length (Lewis 1991 ) and ethylene oxide (EO) molar ratio (Hall et al 1989 ).…”
