| چکیده | ||
| نمونه های بافت کبد از شغال طلایی در شهرستان نور واقع در سواحل مرکزی استان مازندران جمع آوری شدند. میزان ترکیبات آلی کلره پایدار (POPs) از قبیل بی فنیل های پلی کلره (PCBs)، دی کلرودی فنیل تری کلرواتان (DDTs) و متابولیت هایش، هگزاکلرو سیکلوهگزان (HCHs) و متابولیت هایش، هگزاکلروبنزن (HCB)، آلدرین و دی آلدرین در بافت کبد توسط دستگاه GC-ECD تعیین شدند. بیشترین غلظت مربوط به ترکیب ng/g) PCBs 51/41 ± 13/58) و به دنبال آن ترکیبات ng/g) HCHs 88/10 ± 58/10)، ng/g) DDTs 17/6 ± 62/4)، ng/g) HCB 81/0 ± 60/0)، آلدرین(ng/g 78/0± 54/0) و دی آلدرین (g/g ww 18/0 ± 13/0) به ترتیب در رتبه های بعدی قرار داشتند. در این مطالعه از نمونه های تلفات جاده ای (Road-Killed) استفاده شده است. بین غلظت OCPs در جنس نر و ماده اختلاف معنی داری مشاهده نش (904/0> P > 095/0 ) و همچنین هیچ اختلاف معنی داری بین غلظت ترکیبات OCPs با طول بدن و وزن بدن مشاهده نشد. بطورکلی غلظت ترکیبات OCPs پایین تر از حدی بود که باعث اثرات مخرب بر حیوانات شود. | ||

| چکیده [English] | ||
| Liver samples from golden jackal (Canis aureus) were collected from Noor in the central coastline Mazandaran province. The samples of this study were killed in road accidents. Levels of persistent organochlorine pollutants (POPs) including polychlorinated biphenyls (PCBs), DDTs and metabolites, hexachlorocyclohexanes (HCHs) and metabolites, hexachlorobenzene (HCB), aldrin and dieldrin were measured in liver tissue samples by gas chromatography using electron capture detection (GC-ECD). The compound found at the highest concentration was PCBs (58.13 ±41.51 ng/g), followed by the contaminants HCHs (10.58 ±10.88 ng/g), DDTs(4.62 ±6.17 ng/g), HCB (0.60 ±0.81 ng/g), Aldrin (0.54 ±0.78 ng/g) and Dieldrin (0.13 ±0.18 ng/g). There were no significant differences between sexes. Also no significant differences (0.095 < P < 0.904) were found between POPs levels in liver with weight and length of body. POPs levels were generally low; and do not approach levels that are known to potentially cause adverse effects in animals. | ||
