(a) Cumulative total amounts of trapped Se, S and As (error bars indicate the s.d. of the triplicate boxes) in set A in 2012, with linear trend lines and correlation coefficients (R2) thereof. (b) Cumulative total amounts of trapped Se and As (error bars indicate the s.d. of triplicate boxes) in sets A and B in 2010, with polynomial trend lines and correlation coefficients (R2) thereof. (c) Speciation of Se and (d), S in selected traps, with indicated sampling times (from sets A and C, 2012 campaign). The fraction of unidentified species (other species) was determined by the difference between the total elemental determination and the sum of all identified species. Error bars indicate the s.d. of the measurements of triplicate samples.
