Abstract
This study presents an estimation of daily
drinking-water ingestion rates for adults and children under the climatic and
lifestyle conditions of N'Djamena. Water ingestion rates were estimated using
both a segmented linear temperature–intake relationship and a multivariate
equation, based on the mean annual and mean daily maximum temperatures. The
results indicate average values of approximately 4 L·day⁻¹ for adults and 2
L·day⁻¹ for children, which are more representative of Sahelian populations
than the default rates commonly applied in temperate regions. These values are
recommended for use in local human health risk assessments.
