Background and Objective: In this study, some samples of bed sediments from Rasht rivers were obtained and 19 organochlorine pesticides (OCPs) were determined for specifying the contamination profiles, distribution characteristics, effective factors and hazard of carcinogenic compounds. OCPs as Persistent Organic Pollutants (POPS) haskhown vast distribution, persistence and accumulation in the environment. Their high toxicity to humans and non-target organisms are a significant threat to human health and biodiversity.
Method: Identify and determine the concentrations of organochlorine pesticides analysis were conducted on bed sediment samples by liquid-liquid micro extraction method and then by gas chromatography flame ionization (GC-FID) and via external standard calibration curve drawing.
Findings:Based on the analysis, total concentration of OCPs is in the range of 2.6-60.2 ng/g, with an average of 20 ng/g. The main sources of pollution are Heptachlor, HCHs, DDTs and Endosulfans and highest contamination of the dominant pollutant DDE isomers belonges to sediments of Pir Bazar River.
Discussion and Conclusion: The results are showed that there were various amounts of new and past entries. The analysis shows that the potential source of high levels of DDTs and HCHs residues of pesticides returns to the pastconsumptions.

Most of them 17/9% were menopausal in the 50th of their ages. 28/3% of them had used ocp and 68/7% had hot flash. There was not any significant relation between usage of ocp and hot flash.

Irregular increase in the population has been always a hindrance to the development of the countries. So the use of FP programs can stop this irregular increase. Oral combine contraceptive pills are a group of drugs used yearly by 70 millions of women in the USA. These pills have unwanted side effects. One of the side effects is headache seen in some of users. This effect sometimes endangers the continuation use OCPs. Ginger is a root herb with higher antioxidant effects than vit E. It can neutralize free radicals. Free radicals are caused inflammation. In this randomized clinical trial the effects of ginger on headache after OCPs using evaluated in Shiraz. Based on this purpose of study, selecting cases that had studyandrsquo;s criteria was done. So 46 cases selected and randomly divided into two groups, 21 control group 25 treatment groups. The data was collected by questionnaire through clinical examination and personal interview in 1 cycle before and 2 cycle after treatment with ginger. Questionnaire has demographic and headache duration information. After data collecting we used SPSS. In statistical analysis descriptive, analysis and nonparametric measurement chi-square and Cochrane test were used. The results showed that significant decrease on headache between months in ginger group (Pandlt;0/001). It is concluded that ginger because of antioxidant and anti inflammatory effects can relief headache in OCPandrsquo;s user.
