Abstract

Svrha ovog rada bila je utvrđivanje toksičnosti aromatskih spojeva koji su glavni produkti prerade nafte i petrokemijske industrije. U tu svrhu u kontroliranim laboratorijskim uvjetima obavljeno je istraživanje djelovanja fenola i devet hlapljivih aromatskih ugljikovodika na kolnjaka Dicranophorus forcipatus. Uzgojena je čista kultura kolnjaka te je praćena promjena njihove brojnosti tijekom šest dana pod utjecajem odabranih aromatskih ugljikovodika. Dobiveni su rezultati pokazali uglavnom visoku smrtnost kod akutnog trovanja, posebno u prvim danima, pri čemu kod nekih od spojeva dolazi do oporavka kulture. Vrsta D. forcipatus pokazala se dovoljno osjetljivom za procjenu onečišćenja prirodnih, posebno kopnenih voda aromatskim spojevima.

Abstract (english)

The aim of this study was to determine the toxicity of aromatic compounds, which are the main products of the petroleum refining and petrochemical industries. For this purpose the effect of phenol and nine volatile aromatic hydrocarbons on the rotifer Dicranophorus forcipatus was investigated in controlled laboratory conditions. Pure culture of rotifers was cultivated and the change in their abundance was monitored over six days under the influence of selected aromatic hydrocarbons. The results mainly showed high mortality in acute poisoning, especially in the early days, but in some of the experiments recovering of the culture was determined. The species D. forcipatus has proved sufficiently sensitive to evaluate the pollution of natural, especially inland waters by aromatic compounds.
