“…The K oc used to calculate the pore water concentration is based on the regression of log 10 K oc to log 10 K ow according to Equation 4: (4) Based on the effective concentrations of TCS in the spiked sediments for C. xanthus (45.26 µg g -1 ) and C. dubia (6.94 µg g -1 ), these equations were used to obtain the predicted TCS pore water effective concentrations of 47.28 µg L -1 and 7.24 µg L -1 , respectively. Although these estimations should be used carefully, these estimated values are similar to the effective concentrations obtained in other studies in water for algae (Orvos et al, 2002), fishes (Nassef et al, 2010), amphibians (Palenske et al, 2010) and marine bivalves (Cortez et al, 2012), including the NOEC for C. dubia (Orvos et al, 2002) and C. xanthus (Dussault et al, 2008).…”

“…Orvos et al (2002) investigated TCS toxicity in freshwater algae, daphnids and fish and showed effective concentrations ranging from 1.4 to 390 µg L -1, while Ciniglia et al (2005) found geno and cytotoxicity effects at 250 µg L -1 . Cortez et al (2012) observed biological effects from TCS on marine mussels at environmentally relevant concentrations on the order of magnitude of ng L -1. Using bacteria ( Vibrio fischeri) as test organism, triclosan and methyl triclosan have been identified as two of the major organic pollutants currently contributing to the acute toxicity of domestic wastewater (Farré et al, 2008).…”

The purpose of this study was to assess the environmental risk of sediments contaminated with triclosan to thropical aquatic invertebrates. Acute toxicity assays with Chironomus xanthus and chronic toxicity assays with Ceriodaphnia dubia were performed using spiked sediments with environmentally relevant concentrations of triclosan. We obtained a lethal concentration (LC50 96-h) in acute toxicity assays with C. xanthus of 45.26 µg g -1 and a no observed effect concentration (NOEC) and lowest observed effect concentration (LOEC) for C. dubia of 5.78 and 6.94 µg g -1 , respectively. According to equilibrium partitioning theory, these spiked sediment values are equivalent to interstitial water LC50 values of 47.28 μg L -1 for C. xanthus and an LOEC of 7.24 μg L -1 for C. dubia. Our results suggest that sediments contaminated with triclosan represent high risk to freshwater organisms, since this compound has been reported on the order of magnitude of µg g -1 in sediment near discharge of untreated domestic and industrial wastewater.

“…Toxicity tests have been used worldwide with different objectives, such as to determine environmental health, establish maximum limits for the discharge of chemicals and effl uents, defi ne critical areas, and provide a biological understanding of the chemicals found in the environment and among others goals [1][2][3][4]. Most of the purposes cited above require environmental studies (monitoring and assessment) or the establishment of maximum limits for chemical discharge into the environment.…”

Few species are standardized and have been used as test organisms around the world in ecotoxicological assays. In the case of sediment assessment, there are only two amphipod species (Tiburonella viscana and Grandidierella bonnieroides) standardized protocols for toxicity test in South Atlantic region.In order to evaluate the possibility of using the epibenthic marine amphipod Hyale nigra in toxicity tests, a sensitivity test using spiked sediment method was applied, with cadmium chloride as a reference toxicant (CdCl2). Tests with environmental samples were performed to validate the test organisms. The samples were taken from Santos Estuary and Bay in state of Sao Paulo, Brazil. The historical toxicity and contamination are mentioned in the literature. The results obtained in the spiked sediment tests showed little variation in the sensitivity of Hyale nigra amphipod with a mean LC50 value of 5.73 mg.L-1 (1.51 mg.L-1 -8.75 mg.L-1). In the tests with environmental samples, the results obtained were similar to those found in the literature regarding this sampling area. This study demonstrates the potential of Hyale nigra amphipod as a test organism in toxicity tests, once that the specie is sensitive and its results were similar to those reported in the literature on other species of amphipods that are already used in ecotoxicological studies.

“…É um teste sensível, rápido e de baixo custo para a avaliação da toxicidade, sendo importante o desenvolvimento e adaptações de protocolos para espécies nativas brasileiras . Testes embriolarval com o mexilhão Perna perna são aplicados com sucesso em diversos estudos ZARONI et al, 2005;CORTEZ et al, 2012) e fornecem dados para entender o modo de ação de poluentes.…”

“…Os principais cultivos no Brasil ocorrem no estado de Santa Catarina devido a suas características oceanográficas (MARENZI & BRANCO, 2005). As características do mexilhão Perna perna favorecem a absorção e acúmulo de contaminantes, entre eles os poluentes orgânicos persistentes (FRANCIONI et al, 2007), metais (FRANCIONI et al, 2004) e fármacos (CORTEZ et al, 2012), além de absorverem micropartículas de plásticos, já observado na região da baía de Santos, gerando consequências em alterações fisiológicas do organismo (ASCER, 2015).…”
