تقييم الديوكسين/الفوران والعناصر في الدواجن من الزرقاء محافظة الأردن

Tis study is the frst to determine the concentration for 17 congeners of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs) and element contamination in poultry that is close to petroleum refnery at Al-Hashemiya Municipality, Zarqa Governorate, Jordan. Ten diferent samples (chicken) were collected to cover ten diferent locations of poultry farms in Al-Hashemiya Municipality. Tese locations are considered polluted areas as a result of exhaust gases produced from the refnery. Te 17 PCDD/Fs congeners and elements of Pb, Cd, As, Zn, Cu, Se, Hg, Cr, and Ni were determined for three parts of each sample (liver, muscle, and gizzard). All samples were analyzed for PCDD/Fs after a Soxhlet extraction procedure and cleanup by column chromatography; then, all compounds were identifed and determined using GC-MS techniques. Te elements were analyzed after digestion and measured using an inductively coupled plasma optical emission spectrometer (ICP-OES) and validated with the Lab Mix24 RM NCS ZC73016 reference material. Te highest total sum concentration of PCDD/Fs was found in liver samples to be 214.07 ng/kg (dry weight), while the highest sum of toxicity equivalent to PCDD/Fs of 22.54 ng TEQ/kg was found in gizzard samples. For element concentrations, the highest total sum of 16.89 mg/kg (dry weight) was found in liver samples. Te concentration level of the elements of Se, Hg, Cr, and Ni for all parts of the chicken was within an acceptable range according to Jordanian standards and therefore the measured level of heavy and trace elements in the poultry samples (chicken) does not pose a danger to public health. Te chickens found in poultry farms near the refnery are more likely to contain a higher concentration of PCDD/Fs congeners due to exhaust gas exposure
