Influence of zeolites on lead and cadmium content in separate links of trophic chain in hydroecosystems
Information about the influence of zeolite used as adsorbent to reduce the concentration of Lead and Cadmium in separate links of trophic chain of hydroecosystem namelyn in water, phytoplankton and muscular tissue of Silver carp is given in the article. As a sorbent we used zeolite of Sokirnitsa deposit (village Sokirnitsa, Khust district Transcarpathian region) of fraction 1.0 – 4.0 mm. Investigations were made at the Lviv research station of Institute of fisheries NAAS (Lviv oblast, Horodok region, Velykyi Lyubin). The sorption properties of natural Transcarpathian clinoptilolite towards Lead and Cadmium at dynamic conditions have been studied. The paper represents research results aimed at estimating effectiveness of removing of Lead and Cadmium ions from hydroecosystems using natural mineral–zeolite. The dynamics of heavy metals content at phytoplankton and muscular tissue of silver carp (Hypophthalmichthys molitrix Valenciennes, 1844) was studied. Measurements were perfomed in pond № 24 (12) area 0.14 hectares which is fed by waters of the river Vereshchytsia. The pond depth is 1 – 1.5 meters. Results of investigations worked out statistically combining the groups. Considerable lowering of ions content of both metals in water was determined. The lowering of cadmium content in muscular tissue of Silver carp was much noticeable than the content of Lead. Results of such investigations are rather actual and perspective and will help to reduce the content of some toxicants in water medium. Improvement of water ecosystems after use of natural sorbents will guarantee ecologically safe products of fish culture and will increase the efficiency of the branch.
