“…Plasma sex steroids Many authors have investigated the effects of agricultural pesticides on the hormonal regulation of fish reproduction (Gimeno et al, 1996;Mckinlay et al, 2008;Palma et al, 2009aPalma et al, , 2009bSayed et al, 2012;Da Cuña et al, 2013). In this study, the plasma levels of androgens (T and 11-KT) were generally lower in fish from contaminated sites (especially in fish from S4), whereas the levels of E2 were significantly higher at this site compared with fish from the reference site, regardless of the species, sex or season.…”

“…Although forbidden in Benin since 2007, endosulfan is still the most widely used insecticide in the Beninese cotton basin (Agbohessi et al, 2011). Considered an endocrine disruptor (WWF, 2011;OMS-PNUE, 2013), this insecticide inhibits the testes of male fish followed by morphological changes (e.g., atrophy of the lobules and degeneration of the spermatids and spermatozoa) (Srivastava and Srivastava, 1991;Wester, 1991;Foerson et al, 2001;Mckinlay et al, 2007;Palma et al, 2009aPalma et al, , 2009b. According to the Australian Pesticides and Veterinary Medicines Authority (2009), flubendiamide would also disrupt the endocrine glands and could bioaccumulate in fatty tissues.…”

“…At present, negative effects promoted by pesticides on aquatic ecology were prominent (Rodriguez-Mozaz et al 2004, Bajet et al 2012). Pesticides and their metabolites damaged aquatic organisms either directly or indirectly by food chains, which reduced biological diversity and natural ecosystem balance (Palma et al 2009, Wiszniowski et al2011, Hayasaka et al 2012, Van der Oost et al 2013). So the high-toxic and high--residual pesticides which were traditionally used have been forbidden to produce and applicate in China, certain pesticides such as chlorpyrifos (insecticide), chlorothalonil (fungicide) and trifl uralin (herbicide) have been widely used due to their moderate or low toxicity and low residue instead.…”

“…Pesticide residues in the environment are an important source of water pollution due to extensive use of pesticides in agricultural production (Zhou 2008, Palma et al 2009, Smalling et al 2013). According to statistics, the amounts of pesticides used have reached 50-60 thousand tons annually in China, about 80% of which entered the environment directly (Zhou 2008).…”

Applying pesticides to crops is one of the causes of water pollution by surface runoff, and chlorpyrifos, trifl uralin and chlorothalonil are used respectively as insecticide, herbicide and fungicide for crop plants widely. To explore effects of three pesticides on aquatic organisms, superoxide dismutase (SOD) and glutathione S-transferase (GST) activities were determined after 24 h and 48 h exposure of D. magna with ages of 6-24 h to several low concentrations of chlorpyrifos (0. -1 ) respectively. Main reproductive parameters including fi rst pregnancy time , fi rst brood time , the number of fi rst brood and total fecundity after 21 d exposures at the same concentrations of pesticides as described above were also measured. The results showed that the activities of GST increased in lower concentrations and decreased in higher concentrations after 24 h exposure to three pesticides, respectively. The activities of SOD showed the same changes after 48 h exposure. With the time prolonged, the activities of GST decreased while the activities of SOD increased. After 21 d exposure, the fi rst pregnancy time and fi rst brood time were delayed, while the number of the fi rst brood and total fecundity per female decreased with increasing concentrations. These results corroborated that GST activity was more sensitive to those pesticides than SOD activity, and there was a signifi cant relationship between total fecundity and pesticides-dose(r>0.94, n=6), GST activity after 48 h exposure and total fecundity after 21 d exposure (r>0.92, n=6).Unauthenticated Download Date | 5/10/18 8:45 AM

Pesticide exposure impacts not only hatching of dormant eggs, but also hatchling survival and performance in the water flea Daphnia magna

Laboratory ecotoxicity tests and biomonitoring in aquatic systems are currently based on the active component of invertebrate communities. Even though dormant egg banks are crucial for the long term survival and community dynamics of many aquatic organisms, the effects of anthropogenic activities on dormant egg bank dynamics have rarely been studied. In this study we investigated the effects of two pesticides with a different mode of action (carbaryl and fenoxycarb) on hatching of Daphnia magna dormant eggs (ephippia) as well as on survival, growth and reproduction of the hatched neonates. Dormant eggs were exposed to the pesticides simultaneously to incubation under conditions that induce hatching (long daylight and 20°C). Carbaryl had no negative effects on embryonic development or hatching rate up to concentrations almost 1,000 times the median effect concentration (EC 50 ) of neonate survival in acute tests. Fenoxycarb, however, had a significant dose-related effect by delaying or completely stopping the hatching process and caused severe abnormalities in developing individuals. Both pesticides had significant negative effects on survival and reproduction of the hatchlings. These results indicate that, in addition to inducing mortality of active individuals, pesticides can affect zooplankton communities by altering hatching dynamics and life history traits of hatched individuals. We briefly discuss how such pollution induced changes in the benthic-pelagic coupling could translate into transgenerational effects impacting ecological and evolutionary dynamics.
