Background and Objective: Increasing industrial activities associated with the production of pollutants, including heavy metals, is one of the main causes of water and soil pollution. Mineral activities are one of the human activities that cause pollution of the natural resources such as soil. Method: In this study, the zoning concentration of copper as soil contamination around Meyduk copper mine was investigated. The direction samples were taken according to the situation of surrounding villages. Systematic sampling of 360 samples had been collected through the directions. Measuring the concentration of sample was done using atomic absorption method in the laboratory. To indicate the degree of soil pollution with heavy metals, Muller’ s geoaccumulation index was used. Finally, in order to estimate the normal concentration of Cu and pollution of soil, Kriging method was used. Results: Results showed that the maximum amount of Cu concentration is 697. 5 mg/kg and the minimum is 6. 35 mg/kg. The Cu concentration trend in direction D was more than direction M due to the direction of local dominant wind. Discussion and Conclusion: By receding from location of mine, the overall trend of Cu concentration decreased. This indicated the role of mine activities on soil pollution.

Background and Objective: The main goal of this research was “ The Relationship between Personnel’ s Blood Lead Concentration Parameter, Job Stress and Job-Burnout Parameters in Staff of a Battery Manufacturing Company” . Method: It was a descriptive and cross sectional investigation. The sample group (with age range 20-65) included 100 out of 200 staff who worked in the productive lines of company. They were selected randomly. Job Stress (Davies, 1991) and Maslach Job-Burnout (1981) questionnaires were used as tools. Also the lead concentration of whole blood was determined by using atomic absorption spectrometer. Findings: The results of Pearson correlation test showed that there are significant relationship between blood lead concentration with depersonalization and low performance of staff (P<0. 01, P<0. 05). There are significant relationship between stress related to jobs and job-burnout dimensions (P<0. 01). The results revealed that blood lead and job stress can predict depersonalization and weak performance of staff. Discussion and Conclusion: Many workers are in the exposure of chemical hazards like lead concentration simultaneously they are suffering from job stress and different types of pressures because of hard conditions of job in a battery manufacturing companies. These difficult conditions can lead them towards job-burnout (depersonalization and weak performance) too. It was recommended to the managers and engineers to control dust and fumes of lead pollution with respect to occupational health and safety in the workplaces. The management plans should be targeted the job related stress management and prevention of job burnout as well.

BACKGROUND AND OBJECTIVES: Chronology is one of the novel sciences that has been considered by those in power in different eras. During the Timurid period, Alegh Beyg made considerable efforts to link his family to the Genghis dynasty. For this reason, he wrote a genealogical work, entitled Tarikh al-Arba’, e, the original version of which disappeared, but its adapted remains became known as the Al-Atrak genealogy, of which two copies are available today. The aim of this research is to introduce this literary historical work by looking at the literary, linguistic and content layers of Shajrat al-Atrak and with the help of descriptive stylistic method. Considering the stylistic features of this text and the use of descriptive stylistics at three levels of content, language and rhetoric, the period of reproduction and writing of Shajrat al-Atrak and the nature of its author should be examined. METHODOLOGY: The method is analytical and descriptive and the data are collected through phishing and sampling of the text by repeated study and selection of repetitive options and sometimes mentioning rare and rare cases to approach the answer. Questions helped. FINDINGS: Shajrat al-Atrak is one of the historical-literary texts that by introducing and examining its features, gives researchers the opportunity to study in a text that in addition to the vague historical points of the Mongol and Ilkhanid rule in Iran, also in terms of literature and language. It has outstanding features and can connect part of the communication circles of different historical periods of Persian language, literature and culture of Greater Iran. CONCLUSION: Conclusion: Despite all the author's efforts in the use of literary arrays and Arabic words, and moreover Mongolian Turkish, the prose of Shajrat al-Atrak is still simple and like most historical reference texts. What I like most about its prose writing style is the style of sentence writing in inflection, and the chapter and connection of sentences,In such a way that most sentences, regardless of the place of connection and the chapter, are connected with "wow" in turn, making it difficult for the proofreader to connect the sentences. Mistakes in the use of prepositions, quoting Turkish sentences and poems, and even writing text based on the dialect of the Turks of Parsigo, reinforce the author's suspicion that he is a Turkic speaker and that he is probably a Mongol, and that the author claims that the text Alegh Beyg summarizes and approves. Given the author's devotion to the Sunnis, the text seems to have been reproduced in the period before the Shiite religion became official. Considering the rhetorical and linguistic features of the text and its compatibility with the prose of the Timurid period, it seems that the text belongs to the Timurid period and the author is a relative of the Turkic-speaking Ilkhanids.
