Air pollution is getting worse in Viet Nam in recent years, particularly in big cities. The most important source of pollution are traffic and industrial activities. The paper "A Review on Current Status of Urban Air Pollution in Ho Chi Minh city and Ha Noi" reviews air pollution situation in Ho Chi Minh city and Ha Noi. We also recommend policies to tackle the problem: (i) upgrade the national air quality standard, (ii) install systematic and high-quality network of monitor stations, and (iii) remove means of transport that unmet emission regulations.

Modern urban Air Pollution Stagnant air Continuing emissions "summer" (photochemical) smog: NO, NO2, CxHy, UV-rad: == O3 (reactions worked out on blackboard) Winter (cold weather) smog: fine or ultra-fine particles == health effects Mixture is different in different cities Traffic important source Toxicological mechanism still unknown Health effects even at low concentrations (from 40 mg/m3?)
