The results of hydro-chemical studies done in spring (March) and autumn (November) of the river Tsarev flowing along Astrakhan are given in the paper. It is shown that at the beginning of spring there were much more suspended substances in the water than in autumn due to ice melting and drifting. The contents of the dissolved oxygen decreases in autumn. Contents factors of nitrous substances are changed insignificantly, as well as contents factors of oil products. Contents factors of heavy metals fall from the beginning of the year up to the end.
