“…Studies using the POEA formulation found the LC50 values ranged from 2.0 to 4.9 mg/L in RoundupÒ (Giesy et al, 2000;Wang et al, 2005). Previous studies with nonionic surfactants have demonstrated that toxicity increases with increasing alkyl chain length (Dorn et al, 1993;Wong et al, 1997), but this trend was not observed for the ANEO surfactants tested here (Table 1). The wide range of toxicities of different POEA formulations indicates that by altering the structure of the surfactant toxicity can be greatly reduced.…”

Polyethoxylated tallowamine (POEA) is a non-ionic surfactant used in many herbicide formulations to increase the ability of active ingredients to penetrate leaf cuticles. However, it has also been shown to disrupt respiratory membranes in aquatic organisms. In this study, Daphnia magna was used to examine the lethal and sub-lethal toxicity of three POEA formulations consisting of 5:1, 10:1, and 15:1 average oxide:tallowamine. The formulation consisting of 10:1 was the most acutely toxic with a 48-h LC50 value of 97.0 microg/L and 15:1 was least toxic at 849.4 microg/L. All formulations inhibited growth at concentrations between 100 and 500 microg/L.

“…Different processes have been described in the literature for the treatment of these wastes, but the most commonly used are coagulation, precipitation, and biological methods [1]. In wastewater treatment plants, persistent surfactants can give rise to foaming, adsorption onto microbial sludge and loading of the purified effluents in concentrations up to ppm range [2].…”

“…Textile plants have been reported as highly pollutant industrial activities (Dorn et al 1993;Lin and Peng 1994). Villegas-Navarro et al (2001) tested the toxicity of each process of the textile industry and found that none of the processes were atoxic and the dyeing and Bleaching stages were the most toxic to Daphnia magna.…”

Behavioral response of Zebrafish Danio rerio Hamilton 1822 to sublethal stress by sodium hypochlorite: ecotoxicological assay using an image analysis biomonitoring system

et al. 2007

We evaluated behavioral responses of zebrafish Danio rerio exposed to sublethal concentrations of sodium hypochlorite using an image analysis biomonitoring system (IABS). First, the limits of normal variation in swimming activity of zebrafish were determined by monitoring traveled distance of 40 control fishes using the IABS. An acute toxicity test was performed to determine the LC(50(24 h)) for D. rerio to NaOCl. To evaluate the toxic effects in swimming activity, 32 fishes were exposed to 40%, 30%, 20%, 10% of the LC(50 )and 32 were used as control using the IABS. We considered toxic concentrations where more than 10% intervals of the treated group were below the limits of normal variation and were significantly different from the control group. Two main responses were observed: an escape response (increased swimming activity) at 10% treated group, a gradual decrease in swimming activity from the 20% of the LC(50) on, and an avoidance response at higher concentrations. The response of the 20% treated group were considered as a NOAEL and responses of the 30% and 40% treated groups indicated significant hypoactivity (adverse effect). This behavioral biomonitoring system has proven to be a useful tool to detect sublethal toxicity that could be incorporated in biomonitoring protocols in Brazil.
