Mercurio en aguas del sureste de España: posibles fuentes de contaminación

摘要: We determined Hg levels in drinking, irrigation and waste waters from different locations the province of Granada(South-east Spain). A total 74 samples were analysed using cold-vapour atomic-absorption spectrometry, thesensitivity, accuracy precision method verifi ed. was not detected drinking water but valuesin found to range undetectable 0.12 μg/l. Although these values do give cause forgeneral alarm, some sampling points showed clear evidence contamination. However, origins such could notbe identifi ed with any certainty. In light fact that background soil are general fairly low, thehigher recorded seem be attributable anthropogenic activity (extensive use phytosanitory products, urbanand industrial waste,…). wastewater somewhat higher, ranging 2.83 3.95 μg/l, indicating thatsuch a degree contamination requires surveillance periodic controls.
