Many salt collectors work 6–7 hours a day in the lake, which has a salt content of up to 40% in some areas. In order to protect their skin, they rub their skin with "Beurre de Karité" (shea butter, produced from shea nuts obtained from the Shea nut tree), which is an emollient used to avoid tissue damage.
This lake is under consideration by the World Heritage Committee for inclusion as a World Heritage Site.
