| ecotoxicological effects of rice field waters on selected planktonic species: comparison between conventional and organic farming. | the aim of this study was to assess the ecotoxicological effects of water coming from untreated organic and conventional rice field production areas in the ebro delta (catalonia, spain) treated with the herbicides oxadiazon, benzofenap, clomazone and bensulfuron-methyl and the fungicides carbendazim, tricyclazole and flusilazole. irrigation and drainage channels of the study locations were also included to account for potential toxic effects of water coming in and out of the studied rice fields. ... | 2010 | 20721691 |
| predicting concentrations of cytostatic drugs in sewage effluents and surface waters of catalonia (ne spain). | cytostatic drugs, used in chemotherapy, are excreted unchanged by urine and feces or modified as metabolites. elimination of these drugs in wastewater treatment plants (wwtps) is often incomplete and residues reach surface water. their presence in the natural environment depends on consumption patterns, excretion fraction and the effectiveness of the wastewater treatment. this study compiled the total consumption of cytostatic drugs in catalonia (ne spain) and provides data on the occurrence and ... | 2015 | 25721243 |
| determination of cytostatic drugs in besòs river (ne spain) and comparison with predicted environmental concentrations. | the number of cytostatic drugs used in cancer treatments is wide and increases every year; therefore, tools have been developed to predict their concentration in the environment to prioritize those for monitoring studies. in the present study, the predicted environmental concentrations (pecs) were calculated according to consumption data in catalonia (ne spain) for 2014. according to pecs and to the most widely reported compounds, 19 cytostatics were monitored in two sampling campaigns performed ... | 2017 | 28074365 |
