The present study quantifies trace elements such as As, Ba, Cu, Cd, Cr, Fe, Hg, Mn, Pb, and Zn, as well as pH and electrical conductivity (EC), in condensed atmospheric water vapor at three localities in Mexico. Atmospheric water vapor was condensed with an atmospheric water generator prototype. A total of 108 samples were obtained from three survey sites over the course of two seasons (wet and dry) during day/night shifts. The concentration of heavy metals was analyzed using inductively coupled plasma mass spectrometry. The pH and EC parameters were measured with a potentiometer/conductometer. We found Pb, Fe, and Cd in 91.66, 58.33, and 33% of the samples, respectively, at concentrations exceeding those permitted by the World Health Organization (WHO) for water intended for human consumption. Both pH and EC were within the limits established by the Department of Water Affairs of Namibia. The concentrations of trace metals in condensed atmospheric water vapor samples were within the maximum permissible limits determined by WHO for most elements analyzed in this study.]]></p></abstract>
<abstract abstract-type="short" xml:lang="es"><p><![CDATA[RESUMEN La condensación de agua es una técnica que puede aprovecharse para mitigar la escasez de agua para consumo humano. Sin embargo, es necesario garantizar que tenga la calidad suficiente para utilizarse sin comprometer la salud del consumidor. En este trabajo se cuantificaron los elementos traza como As, Ba, Cu, Cd, Cr, Fe, Hg, Mn, Pb y Zn, el potencial hidrógeno (pH) y la conductividad eléctrica (CE), en el agua condensada de la atmósfera en tres localidades de México. El agua se condensó con un prototipo que induce el punto de rocío a partir de la humedad atmosférica. Se obtuvieron un total de 108 muestras en los tres sitios de estudio, en dos épocas del año (lluvias y secas) y en dos turnos (diurno y nocturno). Los metales pesados se analizaron con un espectrofotómetro de plasma acoplado inductivamente (ICP-MS, por sus siglas en ingles). El pH y la CE se midieron con un potenciómetro/conductímetro. Se encontraron Pb, Fe y Cd en 91.66%, 58.33% y 33% de las muestras, respectivamente, en concentraciones que superan la norma de la Organización Mundial de la Salud (OMS) para agua destinada a consumo humano. El pH y la CE están dentro de los límites establecidos por el Departamento de Asuntos del Agua de Namibia. El contenido de metales traza en el agua condensada de la atmósfera cumple con los límites permisibles señalados por la OMS para la mayoría de los elementos analizados en este trabajo.]]></p></abstract>
