The dairy industry particularly dairy farms have been identified as one of the large contributors of antibiotic resistant bacteria (ARB) and ARG in the environment. The unregulated use of antibiotics and the use of disinfectants in the clean in place (CIP) process and heavy metal used for animal feed has been said to result in the induction of antibiotic resistance genes in pathogenic bacteria present in dairy wastewater (DWW). Disinfectant and heavy metals induce antibiotic resistance by inducing efflux pump genes which induce co-selection and cross-selection. There are several studies reporting cross and co-selection between heavy metals, disinfectants such as H<sub>2</sub>O<sub>2</sub> and antibiotics which induce ciprofloxacin and ampicillin resistance in <em>Staphylococcus aureus,</em> while Zn resistance genes(czrC) and methicillin resistance gene (mecA) select for Methicillin-resistant <em>Staphylococcus aureus</em> (MRSA). Controlling the spread of antimicrobial resistance in the environment requires a thorough understanding of their causes. Hence, this review aims to provide an overview of the role chemical materials present in DWW such as CIP chemicals, heavy metals in induction of antibiotic resistance through co- and cross-selection. Additionally, and their mechanism of co- and cross-selection resistance, their pathway to the environment and preventative measures are also discussed.</div></div>","PeriodicalId":34473,"journal":{"name":"Environmental Advances","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142320383","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address this problem, an application has been developed based on an AR-IoT architecture that integrates augmented reality (AR) and the Internet of Things (IoT) for the periodic monitoring of snow cover on the Huascaran snow-capped mountain. This application uses data collected from meteorological repositories and simulates IoT interactions, while a mobile app offers an interactive and understandable visualization of the data. The Scrum methodology was applied iteratively, from the creation of the 3D model to the connection with the Ubidots platform to store and share the data. The analysis of 58 readings, obtained between April and May 2023, showed correlations between variables such as snow depth, temperature, and wind speed, which served to validate the operation of the AR-IoT technology implemented. These variables offer an initial understanding of atmospheric conditions in high mountains. In addition, the technology developed has the potential to expand to include more relevant data in future analyses.

However, these activities generate waste discharged back into the river, which is additionally polluted by untreated domestic wastewater discharges. The main objective was to evaluate the ecological quality of this lotic system, analyzing biotic and abiotic parameters during two seasons. The biotic parameters included microinvertebrates and fecal coliforms, while the abiotic parameters encompassed temperature, pH, dissolved oxygen, electrical conductivity, turbidity, total dissolved solids, and biochemical oxygen demand. Six sampling points were established where physicochemical and microbiological parameters were analyzed. Simultaneously, quantitative sampling of macroinvertebrates was carried out at the same points to evaluate their diversity using Shannon- Wiener, Margalef and Simpson indices. The Andean Biotic Index (ABI) and the Biotic Family Index (FBI) were calculated to determine the ecological quality of the river using macroinvertebrates. Finally, the spatio-temporal variation of macroinvertebrate composition and physicochemical and microbiological parameters were analyzed. Very high concentrations of BOD, total dissolved solids, and electrical conductivity were obtained in the dry season, while in the rainy season, they were pH, dissolved oxygen, and turbidity. 12548 individuals from 6 classes, 11 orders, and 26 families were collected. The greatest richness of macroinvertebrate families was found at points 1 and 2, with Trichoptera, Ephemeroptera and Plecoptera individuals predominating. There was evidence of temporal variation in physicochemical and microbiological parameters, as well as in macroinvertebrate composition. It was concluded that the ecological quality of the Jucusbamba River decreases as it follows its course due to anthropic disturbances.
