Background: In lacustrine communities, whether in Benin or elsewhere, populations use impregnated mosquito nets (IMNs) as fishing nets. This depletes the lake of its fishery resources, which in turn are contaminated by the pyrethroids impregnated in the nets. This study aims to determine the scale and factors associated with the use of pyrethroid-impregnated mosquito nets as fishing tools in the municipality of sô-ava in Benin. Methods: This is a cross-sectional and analytical study with two components. First, a quantitative component was made up of 280 volunteers who were interviewed in the seven districts of the city. Data collection was done in two phases: the first from september to October 2020, and the second in August 2022. Data were analyzed with stata and logistic regression was used. Another qualitative component was made up of forty participants chosen by reasoned choice, of which 32 were split into four focus groups of eight members each, and the rest participated in semi-structured interviews. Triangulation of the different sources was used to analyze the data. Results: Around 67% of the population reported using impregnated mosquito nets as fishing tools and 33% exclusively for malaria. seasonal fishermen (ORa = 2.03, CI = 1.35 - 4.97, P = 0.004) and years of professional experience (ORa = 1.53, CI = 1.00 - 2.05, P = 0.021) increase the risk of using these nets as fishing tools. The use of insecticide-treated mosquito nets against mosquitoes causes skin scratching and impairs breathing because of the impregnation products, as reported by respondents. Conclusion: A high prevalence of inappropriate use of impregnated mosquito nets in fishing practices is highlighted in this study. Interviews in the field revealed that nets are diverted for fishing purposes to increase the volume of catches. Consequently, it will be appropriate to assess the pyrethroid content in water and fishery products.

Access to drinking water in rural and semi-rural areas is a major concern for the populations because of the quality of the resources. This research work aims to analyze the bacteriological quality of the water consumed by households in the Commune of sô-ava in order to establish a relationship between this quality and the health problems observed within the communities. To succeed in this study, documentary research, surveys and observations in the field and analyzes of eighty-two (82) water samples were analyzed in the laboratory during two (2) seasons (rainy and dry). From the results obtained, it appears that the samples present concentrations of total germs, faecal coliforms, Escherichia coli, faecal enterococci, sulphite-reducing anaerobic bacteria (AsR), salmonella and shiguela which do not comply with the water potability standards in respectively 78.05%, 60.98%, 50%, 64.63%, 80.49% and 70.73% of the samples taken. The statistics on the diseases recorded during this decade in the Commune showed that the populations of sô-ava are confronted with several ailments such as: malaria (75%), Acute Respiratory Infections IRA, (16%) and Gastrointestinal disorders (5%) especially during floods and during the rainy season. Education and sensitization of the population on good public hygiene practices around water must be highlighted in order to avoid waterborne diseases.
