Abstract

Magnesium and calcium levels in waters (potable, irrigation, waste and sea waters) from a coastal and industrial zone in south-eastern Spain, have been determined. Acidified water samples were analysed by atomic absorption spectrometry. The samples were previously treated with a matrix modifi er consisting in 0.2 mL of LaCl3 (10 mg/mL La). Magnesium concentrations ranged from 18.2 µg/L to 2286.7 µg/L and those for calcium from 48.8 µg/L to 627.1 µg/L. Mean magnesium and calcium levels in sea water samples were signifi cantly higher (P < 0.001). Magnesium concentrations found in different water groups were signifi cantly and linearly related with corresponding calcium levels (r= 0.942; P < 0.001). Human and industrial activity did not infl uence magnesium and calcium levels in irrigation and sea waters of the zone. Nevertheless, effl uents from the paper factory existing in the zone and from domestic origin increased significantly the calcium concentrations in waste waters.
