Contenido de magnesio y calcio en aguas del área costera Mediterránea del sureste de España y su relación con la actividad industrial (Magnesium and calcium content in waters from the Mediterranean coastal area of south- eastern Spain and their relation with industrial activity)

g/L. Los niveles medios de magnesio y calcio en aguas marinas fueron significativamente superiores (P < 0,001). Las concentraciones de magnesio encontradas en los diferentes grupos de aguas estuvieron linear y signifi - cativamente correlacionadas con los niveles de calcio correspondientes (r= 0,942
g/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 signifi cantly the calcium concentrations in waste waters.
