مراقبة تراكم الملوثات من المعادن الثقيلة في دلتا النيل
تُظهر نتائج تحاليل العينات أن إعادة استخدام مياه الصرف بدون معالجة والتوسع في إنشاء السدود يسبب زيادة تركيز المعادن الثقيلة الملوثة في دلتا النيل مما يهدد بشدة سلامة النظام البيئي والصحي والإنتاج الزراعي في مصر.
Suivie de l’accumulation des métaux lourds dans le Delta du Nil
Les analyses de sédiments montrent que la réutilisation de l’eau non traitée et la construction de barrages entraînent l’augmentation des concentrations de métaux lourds dans le Delta du Nil, menaçant gravement les écosystèmes, l’agriculture et la santé humaine.
