NOx are highly reactive toxic air pollutants which can contribute to acid rain, and ozone layer depletion and pose significant health threats -- particularly in relation to respiratory disease -- contributing to air pollution-related mortality, the researchers said

Adding nitrogen to concrete could significantly lower global levels of potentially dangerous nitrogen oxides (NOx) created by the construction sector in emerging towns and cities, a new study said on Friday.
According to the study published in the journal Nature Cities, concrete nitrogenation could contribute to a reduction in NOx emissions by 3.4-6.9 megatonnes (Mt) -- representing 6 to 13 per cent of industry-related emissions in 2021.
