The objective of this work was to identify possible correlations between physicochemical parameters (water temperature, water flow velocity, electrical conductivity, dissolved oxygen, salinity, pH, nitrates, and phosphates) and the spatial distribution in the Senegal River delta of snail species that are intermediate hosts of human schistosomes. Eight water points (ME1 to ME4, NE1 and NE2, TA1 and TA2) were selected in the villages of Menguègne Boye, Ndellé Boye, and Thilla for biweekly monitoring of these snails and the physicochemical parameters of the water. The results show that the spatial distribution of the snail populations is related to pH, dissolved oxygen (mg/l), conductivity, temperature (̊C), and water flow velocity (m/s).
这项工作的目的是确定物理化学参数（水温、水流速度、电导率、溶解氧、盐度、pH值、硝酸盐和磷酸盐）与作为人类血吸虫中间宿主的蜗牛物种在塞内加尔河三角洲的空间分布之间可能存在的相关性。在Menguègne Boye、Ndellé Boye和Thilla村选取了八个水位点（ME1至ME4、NE1和NE2、TA1和TA2），每两周对这些蜗牛和水的物理化学参数进行监测。结果表明，蜗牛种群的空间分布与pH值、溶解氧（毫克/升）、电导率、温度（摄氏度）和水流速度（米/秒）有关。
