Abstract
  • Dioxin is a general term that describes a group of over hundred chemical polychlorinated aromatic hydrocarbons, which are fitted in three families: polychlorodibenzo-p-dioxins (PCDDs), polychloro dibenzo-pfurans (PCDFs) and dioxin-like polychlorobiphenyls (DL-PCBs). These compounds are highly toxic and persistent in the environment because they are substances which are semi-volatile, thermo-stable, lowpolar, water-insoluble, highly fat-soluble and highly resistant to both chemical and biological degradation. Of these congeners, 17 molecules (PCDDs and PCDFs) and 12 molecules of DL-PCBs are officially analyzed in the environment, including animal products. We analyzed 28 cattle for AC (chromatid breaks, chromosome breaks), 29 cattle for SCE cytogenetic tests and 25 river buffaloes for both tests exposed to dioxins (24.78 and 21.79 pg/g of fat as WHO-PCDD/F/DL-PCB-TEQ, respectively) and raised in the regions of Puglia and Campania (southern Italy), respectively. These animals were compared with two control groups (20 for AC, 23 cattle for SCE tests, and 25 river buffaloes for both tests) raised in the same region but far away from the contaminated areas. In the exposed cattle, of 980 cells examined for AC and 870 for SCE, the mean number of AC/cell and SCE/cell were 0.52 and 7.41, respectively, compared to those of the control (0.16 and 5.30, respectively), the differences being highly significant (P<0.01). In river buffaloes, of 1250 cells studied for AC and 875 for SCE, mean values of AC/cell and SCE/cell were 0.70 and 8.50, respectively, compared to those of the controls (0.28 and 8.29, respectively), the differences being highly significant only for the AC test (P<0.01).
