摘要：In the southwestern part of Burkina Faso, sugar cane is intensively cultivated by the SN-SOSUCO society (Nouvelle Soci�t� Sucri�re de la Como�) which is the largest private employer in the country. The sugar cane is grown on an area covering about 3850 ha. The intensive cultivation of the sugar cane is all the year round and involves the use of pesticides for pest control and to reduce the production losses. Groundwater risk assessment by pesticides used in the SN-SOSUCO cultivated area during the season 2007-2008 was the goal of the present study. Both Pesticide Impact Rating Index (PIRI) software developed by CSIRO Australia and the Groundwater Ubiquity Score (GUS) were used for the evaluation of the thirteen pesticides used by the society. Pichloram, carbofuran, trichlopyr, monosodium methanarsonate (MSMA) and the chlorimuron-ethyl have high leaching potential according to GUS index, and MSMA has mean risk of mobility to groundwater as shown by PIRI. To prevent groundwater pollution by pesticides, the implementation of a comprehensive environmental management system is mandatory.
