An electroanalytical method was developed to detect and quantify the sunscreen agent octocrylene (OCR) in cosmetic products. The method was based on electrochemical reduction, using voltammetric techniques. OCR was reduced at -0.97 V vs. Ag/AgCl on a glassy carbon electrode using a mixture of Britton-Robinson buffer (0.04 mol L(-1)) and ethanol (7 : 3, v/v)(More)
South America and the adjoining oceans are known for having a very irregular and sparse meteorological data acquiring net. The sparcity of data causes the Numerical Weather Prediction models operated by most weather predictions centers to perform worse than they should on computational capability. However, this lack of in situ observations has been(More)
