This data set contains raw data from six laboratories who participated in an interlaboratory comparison exercise using methods described in a new, standardized protocol for assessing hazards of leachable elements in fresh volcanic ashfall. Leachants used were deionized water and a simple gastric leach (0.032 M HCl at pH 1.5). Ratios of 1:20 (g ash:mL leachant) and 1:100 were used for the deionized water leach and 1:100 for the simple gastric leach.
