Three wetland water samples, one each at the entrance, middle and end of the Akwata market were collected and analyzed for the presence of bacteria and fungi. The microorganisms were isolated by culturing on Nutrient, MacConkey and Sabouraud glucose agar plates using standard methods. After the incubation period, the number of unit-forming colonies was counted to determine the average total bacterial count. Bacterial isolates were identified based on colony, microscopic and biochemical reactions. Fungal isolates were identified based on their morphological and microscopic features. Wetland water samples taken at the entrance, middle, and edge of the Akwata market had an average total bacterial count of 1.4 x 104 CFU/mL, 2.0 x 104 CFU/mL, and 1.5 x 104 CFU/mL. Fungal counts were 1.6 x 104 CFU/mL, 3.5 x 104 CFU/mL, and 2.4 x 104 CFU/mL, respectively, in swamp water samples collected at the entrance collected at the middle and end of the Akwata market. Bacterial isolates identified were Escherichia coli (27.58%), Pseudomonas sp. (7.93%), Klebsiella spp. (20.7%) and Salmonella spp. (13.79%). The identified fungal isolate was Aspergillus sp. (38.88%), Candida sp. (16.67%), Fusarium sp. (27.78) and Penicillium sp. (16.67%). This study showed that bacteria and fungi are associated with the swamp water of the Akwata market where tomatoes were sold.

This growing concern has piqued the interest of economists in the field of environmental economics, which focuses on understanding how economic activities of producers and consumers affect our environment. Environmental economists aim to explain policies and initiatives that can improve the quality of life for present and future generations. Environmental issues hold particular significance for developing countries, where widespread poverty exists and there is an urgent need for accelerated economic growth. One crucial aspect of environmental degradation is declining water quality, which can have various impacts on the economy. These impacts can be observed in the health sector, where labor productivity can be affected, as well as in agriculture, where both the quality and quantity of food production may decrease. Furthermore, sectors such as tourism, real estate, aquaculture/fisheries, and others that rely on environmental quality and ecosystem services can also suffer negative consequences. The Bharalu River in Guwahati, Assam, is a prime example of an essential water resource that has undergone gradual degradation over the years, transforming into an urban municipal drain. Once a river flowing with pristine water and teeming with biodiversity, it has now experienced heavy industrialization and urbanization along its course, resulting in alarming pollution levels. This study aims to analyse the economic impact of Bharalu River's pollution from the perspective of consumers. It employs a discrete choice experiment to determine people's willingness to support the ecological restoration of the river and discusses the associated issues and challenges involved in the restoration efforts.","PeriodicalId":253461,"journal":{"name":"Asian Journal of Environment &amp; Ecology","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130313464","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
