| Abstract | A rapid, efficient and low-cost method based on ultrasound-assisted emulsification-microextraction (USAEME) and gas chromatography-mass spectrometry was developed for the analysis of several fungicides, belonging to different chemical families, in white wines. The experimental procedure was optimized using factorial design to study the influence of the solvent type, extraction time, extraction temperature, sample, pH, and salt addition on the extraction efficiency. Under the selected conditions, compounds were extracted into 200 μL chloroform from 10 mL of wine sample in only 5 min at ambient temperature. The method was validated using real wine samples, with fungicide recoveries generally ranging from 70 to 115%, good intra- and inter-day precision (relative standard deviation (RSD) values ≤12%), and limits of detection at the sub-ng per millilitre level (LOD ≤ 0.1 ng mL−1). The application of the method to varietal wines belonging to different brands showed the presence of fungicides in all samples at concentrations ranging from 1 to 700 ng mL−1, with a minimum of two and a maximum of seven chemicals per sample. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
