Abstract

S7rm11~ciy:In the ca.rpet industry of t h e investigated area' in 1980 there were used 100 t of diffvreut chemicals, especiitlly dyes and textile auxiliaries. This quantity is to be increased 2.6 t'imes till 1985. This indiistr-does not hare any closed-cycle drainage systems for the dyeing a n d washing plants. Thus, during eight months of the year tlie effluents infiltrate in the soil or evaporate from 1,ools. The accumulation; cf wastewater originating conta,in up to 60 mgil chroniiuni, so that 1 ... 1 0 11ig;I chroniiuni OCCIII' in tlie wells of tlie area. In the fen-central n-ater-sapply plmts till now chroniiuiii has lint been detected. The annnal variation of the groundwater shows pronounced iiiasinia of coiitaiiiina,tioii during Jiily t o Septcmber, which clearly agree with tlie iiia'sinia, of the ivaste\vater con;entratioiis. The possible ecological impacts of this uncontrclled spread of substances contained in xt-nter also in the nutrient chain are discussed.
