Phosphate values were high and all the samples show bacterial population. The ammonia and nitrite levels are high in Litany River at Jibjanin while the nitrate level is low, this reflect the dominance of anaerobic condition and heavy pollution. Comparatively a better water quality was found in Quaroun Lake reflecting the effects of natural treatment of water. Heavy metals such as lead and cadmium have been detected in Quaroun Lake and Ibrahim river.</p> https://journalofchemistry.org/paper/782/ Litany Damour rivers of Lebanon
