Abstract
Benzo(a)piren (BaP) je poznato genotoksiĉno i kancerogeno zagađivalo koje spada u skupinu policikliĉkih aromatskih ugljikovodika (PAU) koje u morski okoliš može dospjeti prirodnim putem ili djelovanjem ĉovjeka. Kisela DNaza je lizosomalni enzim koji ima važnu ulogu u zaštiti organizma od zagađivala prisutnih u okolišu. U ovom radu utvrđena je aktivnost kisele DNaze za probavne žlijezde i škrge dagnje Mytilus galloprovincialis dodatkom razliĉitih koncentracija (0,01 µg/L, 0,05 µg/L, 0,1 µg/L, 1 µg/L, 10 µg/L, 20 µg/L) BaP-a. Kod kontrolnih vrijednosti u oba istraživana tkiva zabilježene su statistiĉki znaĉajne razlike. U probavnoj žlijezdi uoĉen je porast aktivnosti kisele DNaze sa povećanjem koncentracije BaP-a, dok je u škrgama aktivnost kisele DNaze povećanjem koncentracije BaP-a padala. Iako je vidljiv sezonski odgovor kisele DNaze na uvjete u okolišu, utjecaj zagađivala ostao je primjećen. Probavna žlijezda se smatra kao najaktivniji organ ukljuĉen u metabolizam organskih tvari i biotransformacijskih procesa te je ona u ovom radu pokazala veću osjetljivost na BaP.
Abstract (english)
Benzo(a)pyrene (BaP) is a known genotoxic and carcinogenic agent that belongs to polycyclic aromatic hydrocarbons which can be found in marine environments caused by natural sources or anthropogenic activities. Acid DNase is lysosomal enzyme that plays an important role in the protection of organisms against xenobiotics that occur in the environment. In the present study, acid DNase activity for digestive gland and gills of mussel Mytilus galloprovincialis was determined by adding different concentrations (0,01 µg/L, 0,05 µg/L, 0,1 µg/L, 1 µg/L, 10 µg/L, 20 µg/L) of BaP. In both investigated tissues, control groups expressed significant difference. Digestive gland showed an increase of acid DNase activity following exposure of BaP, while acid DNase activity in gills has been decreased. Although the seasonal response by acid DNase activity on environmental conditions is apparent, the impact of pollutants remained noticeable. The higher acid DNase activity was detected in the digestive gland which is considered to be the most active organ involved in metabolism of organic compounds and biotransformation activities.
