This paper presents the results of the survey on the impact of disposable diaper waste on the environment of the city of Yaoundé in Cameroon. In total, 140 households unequally distributed in the 26 selected districts were surveyed. The neighborhoods have been stratified according to criteria such as socio-economic aspect, access to hygiene and sanitation services, quality of houses. The households surveyed were chosen at random and the interview guides were administered to them. The survey population is young (105 households are between 18 and 38 years old) and 82% are made up of women mothers. 84% of households use around 3 diapers / day for an average of 7 months and the neighborhood shop is the preferred place of supply. Although most (58 households) declare their preference towards the MOLFIX brand for their offspring, others admit generally using around 2 brands in combination. The average mass of used diaper waste produced by a household with a child in the city of Yaoundé is estimated at 120 g / day or 840g / week or 4.32 kg / year of diaper waste. Based on the low frequency of emptying the bins by the hygiene services coupled with the multiplicity of wild piles, it cannot be ruled out that these different exposure routes lead to an increase in environmental risks, particularly through substances. such as: dioxins, furans, formaldehyde contained in baby diapers.
