The approximate linear relationship for each region is notable, suggesting that the dependence of urban NO 2 pollution upon population follows a power law scaling with population. These regions contain two-thirds of total global anthropogenic NO x emissions. Credit: ACS, Lamsal et al. Click to enlarge. for India to 0.66
