RESUMEN
Los diversos contaminantes del aire, presentes en el material particulado respirable MP 2,5, el que representa aproximadamente el 50 por ciento del MP10, causan diversos efectos adversos sobre la salud y aumentan la mortalidad. La Norma Primaria recién aprobada para MP2,5 urbano tiene ventajas en comparación con la norma MP10, pero duplica los niveles de MP2,5 recomendados por la OMS. Más aún, los niveles para decretar medidas de preemergencia o emergencia son permisivos, lo cual hace que la concentración autorizada resulte similar a aquélla que resulta al aplicar la norma actual para MP10. Con la nueva norma MP 2,5 tendremos una norma mejor pero, no mejorará la salud de los habitantes expuestos ni disminuirá la mortalidad por la contaminación. Para fines prácticos la nueva norma es equivalente a la actual para MP10.
ABSTRACT
The various air pollutants present in the breathable particulate matter PM2.5, which represents approximately 50 percent of PM10, cause various adverse health effects and increase mortality. The recently approved regulation for urban PM2.5 presents advantages when compared with the current MP10 regulation, but nevertheless the allowed threshold of MP 2,5 is twice that recommended by WHO. Further, the levels at which pre-emergency or emergency measures would be taken are very permissive, and the concentrations allowed would be similar to those that result from the application of the current PM10 regulation. With the new PM2.5 regulation we will have an improved norm but with authorized levels similar to those resulting from the current regulation. Therefore the health of exposed people will not improve and pollution caused mortality will not diminish.
