We describe here methods for sensitive and accurate quantification of the lesions 8-oxo-7,8-dihydro-2'-deoxyguanosine (8-oxodGuo), 1,N6-etheno-2'-deoxyadenosine (1,N6-dAdo) and 1,N2-etheno-2'-deoxyguanosine (1,N2-dGuo) in DNA. The methods were applied to the assessment of the effects of ambient fine particulate matter (PM2.5) in tissues (lung, liver and kidney) of exposed A/J mice.
