14.2. Volume-weighted mean precipitation chemistry in
7 localities in eastern Spain along the Mediterranean seaboard
(1-7) and in
7 localities from the
European Network (EMEP)
(8-14"). Underlined values in pH and H+ columns correspond to localities were alkaline samples are frequent or dominant; these
values, computed from pH of each sample, do not take into account neutralization by alkaline samples, and underestimate pH (and overestimate H+ concentration)
of the average precipitation solution. Column labelled pHeq gives the correct average air-equilibrated pH in this case, computed from volumeweighted mean alkalinity
