{"doi":"10.17615/azf6-mr65","title":"A Concurrent Exposure to Arsenic and Fluoride from Drinking Water in Chihuahua, Mexico","abstract":"Inorganic arsenic (iAs) and fluoride (F−) are naturally occurring drinking water contaminants. However, co-exposure to these contaminants and its effects on human health are understudied. The goal of this study was examined exposures to iAs and F− in Chihuahua, Mexico, where exposure to iAs in drinking water has been associated with adverse health effects. All 1119 eligible Chihuahua residents (>18 years) provided a sample of drinking water and spot urine samples. iAs and F− concentrations in water samples ranged from 0.1 to 419.8 µg As/L and from 0.05 to 11.8 mg F−/L. Urinary arsenic (U-tAs) and urinary F− (U-F−) levels ranged from 0.5 to 467.9 ng As/mL and from 0.1 to 14.4 µg F−/mL. A strong positive correlation was found between iAs and F− concentrations in drinking water (rs = 0.741). Similarly, U-tAs levels correlated positively with U-F− concentrations (rs = 0.633). These results show that Chihuahua residents exposed to high iAs concentrations in drinking water are also exposed to high levels of F−, raising questions about possible contribution of F− exposure to the adverse effects that have so far been attributed only to iAs exposure. Thus, investigation of possible interactions between iAs and F− exposures and its related health risks deserves immediate attention.","journal":"UNC Libraries","year":2020,"id":136097,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":0,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.8955,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2020-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":546866,"name":"Dana Loomis","orcid":"0000-0003-3297-5200","position":1,"is_corresponding":false},{"id":593704,"name":"Gonzalo G.
