The economic development of Abidjan has as a corollary the galloping demography and the growing production of household waste. The objective of this study is to diagnose the functioning of the household waste sector in the district of Abidjan, particularly in the municipalities of Port-Bouët and Treichville after a concession of the sector to new private operators. This study was carried out through direct surveys and field observations. Thus, households produce as waste peelings (67.6% in Port-bouët and 78.5% in Treichville), food debris (7.4% in Port-bouët and 4.1% in Treichville), plastic (13 % in Port-bouët and 9.3% in Treichville), Balayure (4.2% in Port-bouët and 2.2% in Treichville), glassmaking (0.8% in Port-bouët and 0.7% in Treichville), iron / aluminum (3.7% in Port-bouët and 3% in Treichville), paper (3.3% in Port-bouët and 2.2% in Treichville). In addition, it appears that households have different receptacles for collecting household waste for storage. The latter is done without selective sorting of waste. The collection and transport of waste is done on a daily basis by private operators, as well as their treatment, which is nothing other than landfilling at the recovery and technical landfill center (CVET) of Kossihouen. However, the waste does not pass through a sorting center and recovery in this CVET is at an embryonic stage.

Pesticides used for intensive agricultural production threaten natural resources and human health. The aim of this study is to analyze the use of pesticides in the Marahou
