UNU-EHS and INRES jointly organized a two-day workshop on the monitoring of pesticides and endocrine disruptors on 29-30 July, 2009 in Can Tho, Vietnam. On the first day, four PhD students working in the Work Packages 4330 and 4340 presented their research results to invited scientists from Can Tho University and Hanoi University of Science. On the second day, the results were presented to members of DONRE (Department of Natural Resources and Environment) and the DARD (Department of Agriculture and Rural Development) from Can Tho, Dong Thap and Ho Chi Minh City. The presented results were discussed and very well perceived by the invited guests. In Dong Thap no pesticide monitoring took place until now and the results we presented represents the very first information available for Dong Thap. In Can Tho, pesticide concentrations are analyzed once every five year in the surface water. Thus, the authorities highly appreciated and welcomed our effort to disseminate and discuss our research results.
