Abstract
Introduction: Many calls already perform by cell phones that have need to radiation exposure by users. Because of health reasons and some doubts about effects, this study was conducted to determine the extent of the mobile phones radiations and self report symptoms of users. Material and Method: In this cross-sectional study, 80 available randomly users contain students and staffs of Hamadan University of medical sciences in 2012 were selected. Electro Smog meter TES-593 was used as radiation measurements tool. In order to assess health effects of mobile phones’ radiation, a self-administered survey questionnaire were used. Statistical analyses were performed using T-test, ANOVA and X2 tests by SPSS 11.5. Results: Results showed that the conversation mode had a highest level of electromagnetic indices in the studied cell phones. Compare means of power density that emitted from studied mobile phones had significantly difference (P=0.001). Relationship between exposure to the mobile phones radiation by symptoms of head-ache, anxiety and sleep disturb were significant (P=0.02, P=0.03, and P=0.002 respectively). Conclusion: Although, there is founding the relations between exposure to cell phones electromagnetic fields and some self-reported symptoms in line with same reports, These symptoms can not be absolutely attributed to the use of mobile phones. With these considerations it is recommended that for prevention of health risks from cell phones, safe type selection, control of call duration and frequency of use of these devices should be mentioned.

Abstract
Background and Objectives: This study, based on the DIN 91436 standard framework, examines the role of new approaches in realizing sustainable waste management systems and reducing negative environmental impacts.

Materials and Methods: This review study was conducted through a systematic search of international databases (PubMed, Google Scholar, Scopus, ScienceDirect, and Web of Science) and Persian databases (SID, Magiran, IranMedex, and IranDoc) for articles published from 1990 to 2025. The search strategy included a combination of keywords and articles were selected based on inclusion and exclusion criteria, and then the extracted data were categorized and clarified through thematic analysis.

Results: According to studies, green ergonomics is effective through sustainable design of products and processes, reducing waste at source, and increasing recycling and is in line with the prevention stage within the framework of the DIN 91436 standard. Also, by analyzing human-environment interactions, Ergoecology provides a systematic framework for achieving zero waste with an emphasis on technical, social, and environmental dimensions. By combining these two approaches within the framework of the aforementioned standard, an effective path towards a circular economy and sustainable waste management is mapped out, while investigations of chemists, consist of some materials or methods that can be degraded and damage environment overall and are in contrast with zero waste.

Conclusion: Varity of experimental sciences, researches and technologies finally tag various damages to environment that some of them debated in this study. Achieving zero waste requires the integration of the three main pillars of green ergonomics, ergo-ecology, and the implementation framework of the DIN 91436 standard. This integration not only reduces waste and conserves resources, but also promotes human health and environmental sustainability. To institutionalize this approach, it is necessary to expand interdisciplinary research, incorporate its principles into policymaking, and invest in education and culture among all stakeholders.
