Cytomegalovirus in Bronchoalveolar Lavage

public how to protect against 03. People whose 03 sensitivity is clinically apparent by symptoms or lung function loss are commonly advised to minimize exposure by avoiding outdoor exercise during pollution episodes. The same advice now seems appropriate for clinically "insensitive" individuals, given that they may experience asymptomatic lung function decrements, as well as lung inflammation and permeability effects that could be more harmful in the long term than temporary symptoms and lung dysfunction. Although some people may appear relatively resistant to these effects even during the worst ambient 03 pollution episodes, there is currently no practical way to identify those people, except to perform a controlled 03 exposure. Thus, current laboratory science argues that no group can be assumed to have "low risk" from 03 exposure and that protective efforts should target everyone.
