Seasonal Changes of Metal Accumulation in Water, Sediment and Phragmites austrialis (Cav.) Trin. ex Steudel Growing in Lake Kovada (Isparta, Türkiye)
Abstract
This
study was carried out between April 2014 and January 2015, aimed to determine
heavy metal concentrations in water, sediment and roots, stems and leaves of
the reed (Phragmites austrialis (Cav.)
Trin. ex Steudel) as seasonally from Lake Kovada. During the study temperature,
pH, dissolved oxygen and electrical conductivity of lake water were measured.
In water, Cr was below detection limit (<0.0005) in all seasons, Cd (<0.0004)
in spring, autumn and winter, Ni (<0.0001) in summer, Pb (<0.003) in
spring and summer. Fe has
the highest and Cd is the lowest in water as well as sediment among the studies
metals. Generally, the metal levels in water increased in
winter. Both positive and negative correlations were detected between content
in the water and physico-chemical parameters. Results for levels in water were
compared with national and international water quality guidelines. All metals
were determined in sediment. Metal
levels in sediment increased in spring and summer, decreased in autumn
generally. High levels of heavy metals were found in root of redd, while low
levels in stem and leaf samples depend on metal properties. This results show
that a potential danger may occur in the future depending on the agricultural
development.
