  rdf:value "Smog is the brownish haze that pollutes our air, particularly over cities in the summertime. Smog can make it difficult for some people to breathe and it greatly reduces how far we can see through the air. The primary component of smog is ozone, a gas that is created when nitrogen oxides react with other chemicals in the atmosphere, especially in strong sunlight."@en, "Niebla pardusca que contamina el aire, en particular el de las ciudades durante el verano. Puede dificultar la respiración y reduce significativamente la visibilidad a través del aire. Su componente principal es el ozono, un gas generado cuando los óxidos de nitrógeno reaccionan con otras sustancias químicas en la atmósfera, en especial con luz solar intensa."@es ;
