Abstract

Annual, volume-weighted concentrations ofSO42− in bulk precipitation have declinedsteadily (−0.44 μmol/liter-yr) since 1965 atthe Hubbard Brook Experimental Forest (HBEF), NH inresponse to decreases in regional SO2 emissions(r2 = 0.74). Similar declines in concentrationshave occurred in wet-only precipitation at HBEF and atnearby sites since 1978. However, decreases inSO42− concentrations following passage ofthe U.S. Clean Air Act Amendments in 1990, were notunusual from the perspective of long-term data fromthe HBEF. Statistically significant declines (−5.6mol/ha-yr) in bulk deposition of SO42− also have occurred since 1965 in relation to decreases inSO2 emissions (r2 = 0.58), but annualvariations in deposition also are strongly related toamount of precipitation and other factors.
