Краткое описание

Water quality in the Yarqon river was assessed in May − June 2005 using the methods of bioindication and bioassay. Water quality index (WQI) was also calculated. Among 147 found species of algae and Cyanoprocaryota, 131 species were indicators of the environmental conditions. The saprobic index S ranged from 1.90 to 2.75 (III−IV classes of water quality). It has been found that household sewage from the Kane tributary essentially influence water quality in the Yarqon river. Intensive processes of self-purification within the (β-α-mesosaprobic zones are registered in the river.
