Impact of Yamoussoukro Lakes Water on Lettuce Quality

Waters from lakes, in yamoussoukro city (cote d’ivoire), are usually used for legumes irrigation. however, these lakes were found to be polluted in previous works, inducing probably legume toxicity. the purpose of this work is to draw the relationship between water quality and legume (lettuce) one via their respective physical and chemical characteristics. this study pointed out that, even if lakes were polluted, their characteristics are in the limit of the irrigation water quality standard. in addition, lettuce samples, drawn from the surroundings of lake, respect also fao quality standard. they are, therefore, good for consumption, and no strong relationship is found to exist between irrigation water quality and lettuce one. moreover, we found that this water does not constitute a negative factor for environment.
