Riesgos potenciales de salud por consumo de agua con arsénico en Colima, México

Abstract: Objetivo. Estimar los riesgos potenciales de salud debidos a la ingestión crónica de arsénico (As) en agua en Colima, México. Material y métodos. Se muestrearon aleatoriamente 36 pozos en 10 acuíferos locales. El análisis se hizo mediante ICP-OES siguiendo estándares internacionales. Se realizó una interpolación geoestadística con ArcGIS, implementando un modelo de ponderación del inverso de la distancia, para estimar la ruta de exposición de consumo en cada localidad. Se calcularon los coeficientes de peligro… Show more

“…This NOM has been revised (PROY NOM 250-SSA1-2014) to reduce iAs to 10 μg/L, however, to date, it remains as a draft. 31 Although the implementation of the revised NOM is necessary to reduce the exposure in these populations, the great challenge is to have the technology for removing iAs from drinking water in the contaminated areas of the country with levels above 10 μg/L, as well as to strengthen monitoring and evaluation programs. 32 Information on the levels of iAs in drinking water is more abundant in the northwest and the center-north of the country, and the concentrations show great variations.…”

“…As for the rest of the country, what little information is available suggests the presence of high concentrations of iAs in groundwater; such is the case of Colima, Chiapas and Yucatan, where concentrations ≥25 μg/L have been found. 31,34 If the aforementioned international limits were adopted, it is likely that iAs exposure would emerge as a more extensive problem in Mexico, and updated information would be required to verify it.…”

“…If the exposure exceeds the LOAEL, the subject is at risk of developing cancer in internal organs and other types of more severe injuries [22].…”

“…For carcinogenic risk, exposure to As was estimated for the adult population considering that carcinogenic risk (CR), in general, increases throughout life; therefore, the reference was determined for an individual who consumes 2 L of water/day and weighs 70 kg [22]. This is based on the EPA [9] and ATSDR [22,23], and therefore, it is calculated considering the exposure dose by the cancer dependent factor (CSF), which is 1.5 (Table 1). To verify the validation of the calculated data, the following formula was applied:…”

“…En los últimos años se han registrado muchos metales pesados, que se clasifican como prioritarios por su potencial riesgo a la salud, aquí se considera su abundancia en aguas residuales o de desecho y el riesgo de exposición. La existencia de estos en muchos cuerpos acuáticos como en México y muchas partes del mundo han provocado una alerta en el sector salud, así como en el ambiental [27,[30][31][32][33][34], algunos de estos son: cadmio, mercurio, arsénico, cobre y plomo (ver Tabla 1.6), los cuales en altas concentraciones suele presentar problemas muy graves de salud, como lo son: complicaciones pulmonares, intestinales, con el riñón, además de ceguera, cáncer y otras complicaciones que llevan a la muerte [30,35].…”
