El cambio clim\u00e1tico podr\u00eda aumentar significativamente los niveles de ars\u00e9nico en el arroz de cultivo inundado, un alimento b\u00e1sico para millones de personas en Asia, seg\u00fan revela un nuevo estudio realizado por investigadores de la Escuela de Salud P\u00fablica de la Universidad de Columbia (EE UU) y publicado en The Lancet Planetary Health.<\/p>\n

La investigaci\u00f3n demuestra que el incremento de temperaturas por encima de 2\u00b0C, junto con el aumento de los niveles de di\u00f3xido de carbono (CO2), provoca mayores concentraciones de ars\u00e9nico inorg\u00e1nico en el arroz, lo que podr\u00eda elevar los riesgos para la salud en las poblaciones asi\u00e1ticas de aqu\u00ed a 2050.<\/p>\n

\u00abNuestros resultados sugieren que este aumento en los niveles de ars\u00e9nico podr\u00eda incrementar significativamente la incidencia de enfermedades card\u00edacas, diabetes y otros efectos\u00bb, explic\u00f3 Lewis Ziska, profesor asociado en Columbia.<\/p>\n

El estudio, realizado en colaboraci\u00f3n con la Universidad Johns Hopkins (EE UU) y la Academia China de Ciencias, revela que los mayores niveles de ars\u00e9nico se deben probablemente a cambios en la qu\u00edmica del suelo relacionados con el clima, que favorecen formas de ars\u00e9nico que pueden ser absorbidas m\u00e1s f\u00e1cilmente por el grano de arroz.<\/p>\n

<\/a><\/p>\n

28 variedades, 10 a\u00f1os, siete pa\u00edses<\/h2>\n

Los investigadores midieron los efectos del aumento de temperaturas y del CO2 en 28 variedades de arroz durante diez a\u00f1os en el campo y combinaron t\u00e9cnicas avanzadas de modelizaci\u00f3n para estimar las dosis de ars\u00e9nico inorg\u00e1nico y los riesgos para la salud en siete pa\u00edses asi\u00e1ticos: Bangladesh, China, India, Indonesia, Myanmar, Filipinas y Vietnam.<\/p>\n

Las proyecciones del estudio para 2050 sugieren un fuerte aumento en los casos de c\u00e1ncer, particularmente c\u00e1nceres de pulm\u00f3n y vejiga. Se prev\u00e9 que China registre el mayor n\u00famero de casos, con una estimaci\u00f3n de 13,4 millones de c\u00e1nceres vinculados a la exposici\u00f3n al ars\u00e9nico a trav\u00e9s del arroz.<\/p>\n

\u00abLos efectos toxicol\u00f3gicos de la exposici\u00f3n cr\u00f3nica al ars\u00e9nico inorg\u00e1nico est\u00e1n bien establecidos e incluyen c\u00e1nceres de pulm\u00f3n, vejiga y piel, as\u00ed como cardiopat\u00eda isqu\u00e9mica\u00bb, se\u00f1al\u00f3 Ziska. \u00abLa evidencia emergente tambi\u00e9n sugiere que la exposici\u00f3n al ars\u00e9nico puede estar vinculada a la diabetes, resultados adversos del embarazo, problemas del neurodesarrollo y efectos en el sistema inmunol\u00f3gico\u00bb.<\/p>\n

Estiman que China sufrir\u00e1 unos 13,4 millones de c\u00e1nceres vinculados a la exposici\u00f3n al ars\u00e9nico a trav\u00e9s del arroz en 2050<\/p>\n

Los investigadores proponen varias acciones para reducir la exposici\u00f3n al ars\u00e9nico en el futuro, incluyendo mejoras en el cultivo de plantas para minimizar la absorci\u00f3n de ars\u00e9nico, mejor gesti\u00f3n del suelo en los arrozales y pr\u00e1cticas de procesamiento m\u00e1s eficientes, junto con iniciativas de salud p\u00fablica centradas en la educaci\u00f3n del consumidor y el monitoreo de la exposici\u00f3n.<\/p>\n
