  A total of 75 samples of two species of cyprinid fishes, Cyprinus carpio and Capoeta sp., were collected from three sections of the upper, middle and lower parts of the Kor River in the Fars province, and were analyzed for the determination of Pb, Hg, Cd and As concentrations by the Induction Coupled Plasma method. The average concentrations of Pb in muscle tissues of male Cyprinus carpio and Capoeta sp. were 0.77 ± 0.19, 0.41 ± 0.14 (mg kg- 1); while they were 1.03 ± 0.66, 0.42 ± 0.45 (mg kg- 1) for Hg, 0.08 ± 0.01, 0.08 ± 0.01(mg kg- 1) for Cd and 0.51 ± 0.06, 0.36 ± 0.11 (mg kg- 1) for As (Mean ± SE), respectively. In female Cyprinus carpio and Capoeta sp., the concentrations of Pb were 0.66 ± 0.20 and 0.41 ± 0.15 (mg kg- 1), Hg were 0.49 ± 0.45 and 0.32 ± 30 (mg kg- 1), Cd were 0.24 ± 0.01 and 0.26 ± 0.02 (mg kg- 1) and As were 0.39 ± 0.12 and 0.42 ± 0.13 (mg kg- 1), respectively. The concentrations of heavy metals in mid sampling zone were significantly (P < 0.05) higher than the two other zones; while no significant differences (P > 0.05) were seen in heavy metals assay between the two sexes and species.
The results showed industrial activities around the mid sampling zone of Kor River have polluted the River and the maximum concentrations of Pb, Hg and As residues in fish muscles were 1.46, 0.64 and 1.34 mg kg- 1, which are higher than the maximum levels allowed in fish filets by Environment Protection Agency (EPA) (2, 1 and 5 mg kg- 1), and are therefore not suitable for human consumption.

  The aim of study was to determine the extent of Anabolic Steroids (AS) exposure of athletes of Qom, Iran in sport clubs. AS are a group of synthetic steroid hormones which have the potential to alter the normal functioning of the endocrine system in wildlives and humans and sharp increase of some diseases have been shown to have direct relation with increase to their exposure. Many athletes use Performance-Enhancing Drugs (PEDs) in training and even competitions. It has been shown that some PEDs have capacity to disturb normal endocrine system and increases of some disorders in athletes have been related to continuous exposure to AS. Here, the amounts of athletes` exposure to AS in Qom sport clubs have been studied. The results showed that nearly in all sport clubs different types of supplementary diets, were used up to 750 days and it were more common in athletes of fitness and aerobic fields which mainly recommended by couches. More than 15.6% of 62 PEDs used in Qom sport clubs had been confirmed and registered as AS, mainly they were steroid hormones derivatives such as testosterone, prohormones, anabolic steroids, vinsterol, sevestanol, oxymetolone, nanderlone, anadrol (oxybolone) and oxandelone and they were common between athletes of aerobic and fitness fields. Significant differences (p<0.05) were found between the numbers, types and duration of PEDs usage, field of sport activity and PEDs advisors while highly significant (p<0.001) difference found between male and female sexes. By considering the finding of this study and the extent of AS usage by athletes, it would be possible to see a sharp surge in hormone dependent disease in Qom so urgent action should be taken.
