✦ Synopsis

Various species including nitrate, HNO 3 and Pb were sampled in Antigonish, Nova Scotia and their fluctuations were compared to those of simultaneously sampled acid and sulphate (reported previously). The 24 hr average aerosol nitrate, ~ 0.3 gg m -3, was similar in the summer and winter. Nitric acid made up ~4 2 ~ of the total (aerosol and gaseous) nitrate in the summer and winter, but nitrate and HNO3 were correlated only in the summer. Windroses are used to show the dependence of sulphate, nitrate and aerosol acid on wind direction. Lead had a 24 hr average concentration of 71 ng m -3, was of mainly local origin and was not able to be correlated with other parameters.
