Fecal Pollution Drives Antibiotic Resistance and Class 1 Integron Abundance in Aquatic Environments of the Bolivian Andes Impacted by Mining and Wastewater

et al. 2020

An increased abundance of antibiotic resistance genes (ARGs) in aquatic environments has been linked to environmental pollution. Mining polluted sites with high concentration of metals could favor the in situ coselection of ARGs, whereas wastewater discharges release fecal antibiotic resistant bacteria in the environment. To study the effect of human fecal contamination and mining pollution, water and sediment samples affected by mining activities and sewage discharges were collected from three lakes in Bolivia, the pristine Andean lake Pata Khota, the Milluni Chico lake directly impacted by acid mine drainage, and the Uru-Uru lake located close to Oruro city and highly polluted by mining activities and human wastewater discharges. Physicochemical parameters, including metal composition, were analyzed in water and sediment samples. ARGs were screened for and verified by quantitative polymerase chain reaction (PCR) together with the mobile element class 1 integron (intl1), as well as crAssphage, a marker of human fecal pollution. The gene intl1 was positively correlated with sul1, sul2, tetA, and blaOXA-2. CrAssphage was only detected in the Uru-Uru lake, and its tributaries and significantly higher abundance of ARGs were found in these sites. Multivariate analysis showed that crAssphage abundance, electrical conductivity, and pH were positively correlated with higher levels of intl1 and ARGs. Taken together, our results suggest that fecal pollution is the major driver of higher levels of ARGs and intl1 in environments contaminated by wastewater and mining activities.

“…Contamination of water bodies by arsenic causes a severe threat to the environment and human health, even at low concentrations, owing to its toxicity, mutagenicity and carcinogenicity [1][2][3]. In addition to the natural wreathing of arsenic enriched minerals, the anthropogenic activities including mining, industrial processes and agricultural practices, also substantially contribute to the arsenic pollution [4][5][6]. Typically the arsenate, As(V), is the prevalent species of arsenic especially in natural surface waters [7].…”

Mn-doped La 2 O 2 CO 3 (MnL) exhibited superior arsenate capture capacity of 555.6 mg/g.• The residual of As(V) was well below the permissive value for drinking water.• Doping with Mn atoms enhanced adsorption sites and reduced adsorption energy.• Surface complex and anion exchange dominated As(V) removal at low As (V)/MnL ratios.• Forming LaAsO 4 precipitates contributed greatly at high As(V)/MnL ratios.

This review summarizes over 280 studies published in 2019 related to the characterization, control, and management of urban stormwater runoff. A summary of quantity and quality concerns is provided in the first section of the review, serving as the foundation for the following sections which focus on the control and treatment of stormwater runoff. Finally, the impact of stormwater control devices at the watershed scale is discussed. Each section provides a self-contained overview of the 2019 literature, common themes, and future work. Several themes emerged from the 2019 literature including exploration of substrate amendments for improved water quality effluent from stormwater controls, the continued study of the role of vegetation in green infrastructure practices, and a call to action for the development of new models which generate reliable, computationally efficient results under the physical, chemical, biological, and social complexity of stormwater management. © 2020 Water Environment Federation • Practitioner points • Over 280 studies were published in 2019 related to the characterization, control, and treatment of urban stormwater. • Studies on bioretention and general stormwater characteristics represented the two most common subtopics in 2019. • Trends in 2019 included novel substrate amendments, studies on the role of vegetation, and advancements in computational models.
