“…These values are in the same order of magnitude as the environmental concentrations of TCS in sediments. Considering that the use of TCS have been increasing over the last years, and this compound persists and accumulates in sediments (Cantwell et al, 2010;Huang et al, 2015), environmental levels can reach C. dubia's LOEC for reproduction. The high octanol/water partition coefficient (K ow = 4,76) of TCS indicate uptrend adsorption of this compound on organic matter and accumulation in biota and sediment.…”

“…Since TCS tends to accumulate in sediments due to its relative hydrophobicity and half-life in sediments (40 days) (Huang et al, 2015), it is important to understand the effects of this compound on benthic species. It is also important to note that few data exist about triclosan's effects on benthic tropical species.…”

“…Dehydrogenase (DHA) reflects the total oxidative activity of microbes, which play a significant role in the biological oxidation of organic matter. The methods of measuring the four enzyme activities were previously described by Huang et al (2015).…”

“…Os altos valores dos coeficientes de partição octanol-água (Kow) do TCS, IBU e EE2 indicam alta tendência de adsorção destes compostos à matéria orgânica e acumulação na biota e em sedimentos. Além disso, estudos demonstram que estes compostos são altamente resistentes a degradação no ambiente, com tempos de meia vida de 40, 19 e 108 dias, respectivamente (Conkle et al, 2012;Zuo et al, 2013;Huang et al, 2015). De acordo com Barel-Cohen et al (2006) foi reportada em concentrações na faixa de 43 a 130,7 ng.g -1 na Baía de Cádiz, Espanha (Agüera, et al 2003;Pintado-Herrera, et al 2013), e de 0,3 a 9,6 ng.g -1 em sedimentos estuarinos de Guadalete River, sudeste da Espanha (Pintado-Herrera, et al 2014).…”

“…g.mol -1 , com constante de dissociação pKa = 7,9 e coeficiente de partição octanol/água log Kow = 4,76. Devido sua baixa solubilidade, o TCS possui forte ligação com sedimentos, apresentando tempo de meia-vida de mais de 40 dias (USEPA, 2008b;Walters et at., 2010;Huang et al, 2015). O composto utilizado no presente estudo é de procedência da Sigma-Aldrich com pureza ≥97%.…”
