The subsequent industrial production of billions of tonnes of synthetic nitrogen fertilisers - particular after the 1950s - have flooded terrestrial and aquatic ecosystems with reactive nitrogen, and supported the century's human population explosion.

But the traffic increase has slowed progress in reducing emissions further, and people in many areas still suffer from nitrogen-related air pollution, including small particulates that get sucked deep into the lungs, and ground-level ozone - a strongly irritant gas formed by the action of sunlight on reactive nitrogen.
