“…According to Shimada Borges et al (2013), in studies with Nile tilapia (Oreochromis niloticus), the gills of teleost fish are potentially useful to assess eutrophication, because these organs are in direct contact with the water and act as a selective interface between the organisms and the environment. Besides their respiratory function the gills of fish are also responsible for the acid-base balance, osmoregulation, excretion and reception of stimuli (Sayer and Davenport 1987, Laurent and Perry 1990, Randal and Wright 1990, Bailly et al 1992, Partearroyo et al 1992). However, it was found that the gill covers in young fish can transmit a considerable fraction of the Values given are mean ± standard deviation of three independent replicates * Significant differences as compared to the control (p \ 0.05) Fig.…”

Assessment of the impact of chlorophyll derivatives to control parasites in aquatic ecosystems

Several research groups have studied new biopesticides which are less toxic to the environment and capable of controlling the vectors of parasitic diseases, especially in aquatic ecosystems. Pest control by photodynamic substances is an alternative to chemical or other measures, with chlorophyll and its derivatives as the most studied substances supported by their easy availability and low production costs. The impact of chlorophyll derivatives on four different species, a small crustacean (Daphnia similis), a unicellular alga (Euglena gracilis) and two species of fish (Astyanax bimaculatus and Cyprynus carpio) were tested under short-term conditions. In addition, the effects of long-term exposure were evaluated in D. similis and E. gracilis. In short-term tests, mortality of D. similis (EC50 = 7.75 mg/L) was most strongly affected by chlorophyllin, followed by E. gracilis (EC50 = 12.73 mg/L). The fish species showed a greater resistance documented by their EC50 values of 17.58 and 29.96 mg/L in C. carpio and A. bimaculatus, respectively. A risk quotient is calculated by dividing an estimate of exposure by an estimate of effect. It indicated that chlorophyll derivatives can be applied in nature to control the vectors of parasitic diseases under short-term conditions, but long-term exposure requires new formulations.

“…Furthermore, cadmium transfer across the perfused gills of rainbow trout was found to be enhanced in the presence of LAS at environmentally-relevant concentrations (50 µg/L), although at high concentrations (34.8 mg/L) LAS had a negative impact on gill viability (Pärt et al, 1985). Similarly, it has been observed that anionic surfactants increase the rate of diffusion of urea across perfused rainbow trout gills (Partearroyo et al, 1992). …”

The influence of a surfactant, linear alkylbenzene sulfonate, on the estrogenic response to a mixture of (xeno)estrogens in vitro and in vivo

The influence of a surfactant, linear alkylbenzene sulfonate, on the estrogenic response to a mixture of (xeno)estrogens in vitro and in vivo. AbstractThe effect of the presence of a surfactant on the activity of a mixture of environmental estrogens was assessed. In their natural habitat, fish are subject not only to exposure to mixtures of estrogenic compounds, as has been addressed in previous publications, but also to other confounding factors (chemical, physical and biological), which may, in theory, affect their responses to such compounds. To assess the potential for such interference, the commonly occurring surfactant, linear alkylbenzene sulfonate (LAS), was applied to the yeast estrogen screen at various concentrations, independently and together with a mixture of estrogens at constant concentrations. LAS enhanced the estrogenic activity of the mixture, an effect which became less pronounced over the course of time. This information was used to design an in vivo study to assess induction of vitellogenin in fathead minnows exposed to the same mixture of estrogens plus LAS. A similar trend was observed, that is, the response was enhanced, but the effect became less pronounced as the study progressed. However, the enhanced response in vivo only occurred at the highest concentration of LAS tested (362 µg/L), and was transient because it was no longer apparent by the end of the study. Although LAS is a significant contaminant in terms of both concentration and frequency of detection in the aquatic environment, these data do not suggest that it will have a significant impact on the response of fish to environmental estrogens.

“…Triton X-100 at concentrations over the critical micellar concentration induced lysis of isolated gill epithelial cells in Oncorhynchus mykiss (103); however, Triton X-100 showed a lower effect than ionic surfactants (104). Emulgen 913 (polyoxyethylene glycol nonylphenyl ether) significantly decreased the concentration of metal-binding proteins in the hepatopancreas and lessened the heme-oxygenase activity in the kidney of red carp (105).…”
