Aggravating O3 pollution due to NOx emission …
During the past five years, China has witnessed a rapid drop of nitrogen oxides (NO x) owing to the wildly-applied rigorous emission control strategies across the country.However, ozone (O 3) pollution was found to steadily deteriorate in most part of eastern China, especially in developed regions such as Jing-Jin-Ji (JJJ), Yangtze River Delta region (YRD) and Pearl River Delta region (PRD).
Vehicle emissions control - Wikipedia
These studies ultimately attributed a significant portion of air pollution to the automobile, and concluded air pollution is not bounded by local political boundaries. At that time, such minimal emission control regulations as existed in the U.S. were promulgated at the municipal or, occasionally, the state level.

Pollution - Wikipedia
Pollution is the introduction of contaminants into the natural environment that cause adverse change. Pollution can take the form of stone substances or energy, such as noise, heat or light. Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants.Pollution is often classed as point source or nonpoint source pollution.
