Martínez-Oviedo A, Monterrubio-Martínez E, Tuxpan-Vargas J. Assessing the water contaminants in San Luis Potosi and its effects on its inhabitants: An interdisciplinary study on environmental contamination and public health. JOURNAL OF HAZARDOUS MATERIALS 2024; 464:132828. [PMID: 37952332 DOI: 10.1016/j.jhazmat.2023.132828] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/22/2023] [Revised: 10/19/2023] [Accepted: 10/20/2023] [Indexed: 11/14/2023]
Abstract
Water shortage and contamination is a problem worldwide, impacting the human health. This research provides a comprehensive assessment of water quality and its possible impact on public health in San Luis Potosi, a region in Mexico facing critical water challenges. Throughout the study of various pollutant sources, the contaminants were identified and analyzed. The study focuses on four contaminants; fluoride, zinc, Total Dissolved Solids (TDS), and arsenic, which are prevalent in the region's water sources. By analyzing water samples from 28 locations over an 8-year period and correlating the data with health information, the study identifies potential links between water quality and prevalent diseases. Analytical methods adhere to international standards, including the official Mexican standards (NOM), as well as data from authoritative sources like the National Water Commission (CONAGUA) and the ministry of health. With the quantification of the impact on human health, this research paper contributes to associating the main diseases in the population with the contaminants and the main activities of the city. The consequence of each compound is described in detail. The findings suggest that waterborne diseases and health issues may be related to the presence of contaminants in water. To integrate hydrological and health data, Geographic Information Systems (GIS) were employed to spatially align the data, allowing for the examination of potential spatial correlations between water quality and public health. This research emphasizes the urgent need for targeted water quality management and public health interventions to safeguard the well-being of the local population and promote sustainable water management practices.

Radioiodine therapy during the COVID-19 pandemic in a public reference hospital in Brazil: an experience report. RADIATION PROTECTION DOSIMETRY 2023:7185625. [PMID: 37247636 DOI: 10.1093/rpd/ncad163] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/19/2022] [Revised: 04/04/2023] [Accepted: 05/03/2023] [Indexed: 05/31/2023]
Abstract
COVID-2019 has resulted in an emerging respiratory infection that has spread as a pandemic since January 2020. Nuclear Medicine Services and its workers experienced a dramatic change in their clinical routine. They were required to adjust protocols for this new health condition. Regarding radioiodine therapy (RIT), initial orientations were to postpone treatments. In Brazil, National Nuclear Energy Commission prepared guidelines. It authorized RIT to employ activities over 1850 MBq in an outpatient setting on an exceptional basis. This study reports the RIT experience of a Brazilian hospital during the COVID-19 pandemic, intending to evaluate the applicability of outpatient treatment employing over 1850 MBq of I-131 on a large scale. During referred period, 106 patients at our service had an indication for RIT, of which 58 agreed to participate in the research and provided informed consent. Majority of patients did not meet the minimum requirements for outpatient treatment using doses > 1850 MBq.

THE SCIENCE OF THE TOTAL ENVIRONMENT 2021; 774:145721. [PMID: 33610994 PMCID: PMC7870439 DOI: 10.1016/j.scitotenv.2021.145721] [Citation(s) in RCA: 76] [Impact Index Per Article: 25.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/15/2020] [Revised: 02/01/2021] [Accepted: 02/04/2021] [Indexed: 04/14/2023]
Abstract
The COVID-19 outbreak circulating the world is far from being controlled, and possible contamination routes are still being studied. There are no confirmed cases yet, but little is known about the infection possibility via contact with sewage or contaminated water as well as with aerosols generated during the pumping and treatment of these aqueous matrices. Therefore, this article presents a literature review on the detection of SARS-CoV-2 in human excreta and its pathways through the sewer system and wastewater treatment plants until it reaches the water bodies, highlighting their occurrence and infectivity in sewage and natural water. Research lines are still indicated, which we believe are important for improving the detection, quantification, and mainly the infectivity analyzes of SARS-CoV-2 and other enveloped viruses in sewage and natural water. In fact, up till now, no case of transmission via contact with sewage or contaminated water has been reported and the few studies conducted with these aqueous matrices have not detected infectious viruses. On the other hand, studies are showing that SARS-CoV-2 can remain viable, i.e., infectious, for up to 4.3 and 6 days in sewage and water, respectively, and that other species of coronavirus may remain viable in these aqueous matrices for more than one year, depending on the sample conditions. These are strong pieces of evidence that the contamination mediated by contact with sewage or contaminated water cannot be ruled out, even because other more resistant and infectious mutations of SARS-CoV-2 may appear.

Abstract
In 2020, the world experienced its very first pandemic of the globalized era. A novel coronavirus, SARS-CoV-2, is the causative agent of severe pneumonia and has rapidly spread through many nations, crashing health systems and leading a large number of people to death. In Brazil, the emergence of local epidemics in major metropolitan areas has always been a concern. In a vast and heterogeneous country, with regional disparities and climate diversity, several factors can modulate the dynamics of COVID-19. What should be the scenario for inner Brazil, and what can we do to control infection transmission in each of these locations? Here, a mathematical model is proposed to simulate disease transmission among individuals in several scenarios, differing by abiotic factors, social-economic factors, and effectiveness of mitigation strategies. The disease control relies on keeping all individuals’ social distancing and detecting, followed by isolating, infected ones. The model reinforces social distancing as the most efficient method to control disease transmission. Moreover, it also shows that improving the detection and isolation of infected individuals can loosen this mitigation strategy. Finally, the effectiveness of control may be different across the country, and understanding it can help set up public health strategies.
