Smoking is the major cause of chronic bronchitis, but "... air pollution and dust or toxic gases in the environment or workplace also can contribute to the condition. In some people, chronic inflammation of the airways leads to asthma," according to thiis Mayo Clinic article. Prevention would obviously include not smoking, using unscented and non-toxic products in the home, workplace, and on your person, and avoiding indoor and outdoor pollution such as auto exhaust, smoke, and even fake buttery popcorn that pervades the lobbies of movies.
