Singh, K. Maharaj Kumari, Ashok Kumar, S. Srivastava] Levels of formate and acetate in dew were measured at Dayalbagh, India, usingsurrogate surfaces. The dew formed per night ranged between 0.06 lm−2 and 1.38 l m−2, with an average of 0.59l m−2. pH ranged between 6.7 and 7.4. Mean concentrations offormate and acetate in dew were 10.2 ± 10.2 μeql−1 and 7.5 ± 4.5 μeq l−1,respectively. The correlation coefficient between the two ions was 0.80 (p =0.001), which suggested that concentrations of these species in dew are linkedtogether. They have either common or different sources with fairly constantstrengths or products of same reaction. Good correlation of formate andacetate with Ca (r = 0.82 and r = 0.70, respectively) and Mg (r = 0.74 and r= 0.71, respectively) suggested that these ions may be associated with Ca andMg after the neutralization process. Deposition rates for formate and acetatein dew per night were 10.2 ± 7.22 μmol m−2 pernight and 4.6 ± 2.2 μmol m−2 per night,respectively. The theoretical Henry's law constant (K* H)and the field-observed Henry's law coefficient (K* H) ascalculated from concurrent measurements of gas phase and dew for both acidsshowed large discrepancies of three orders of magnitude.
