Abstract
Occupational cancers account for a major part of cancers. So far, various occupational factors have been recognized as a risk factor involved in the development of different occupational cancers. Prostate cancer is one of the cancers on which various studies have been carried out to examine the role of occupational exposures. The studies have introduced numerous occupational factors and jobs regarding this cancer. The results of studies in this regard have some contradictions. In this short review, occupational risk factors in the development of occupational cancers have been studied. The focus of this study is mainly on the factors, while occupations have not been examined in depth.

Abstract
Background: activity in hot environments is among the most common physical dangers in work environments that not only creates diseases resultant from heat which influences on staff’s health but also increases job injuries and accidents. Job injuries, diseases, and reduction in workers' efficiency in exposure to heat stress have caused increasing anxiety. Most of the study results are demonstrative of diseases as a result of heat and less related to job injuries and accidents. Therefore, the present study aims at reviewing previous studies in the field of job injuries and accidents in exposure to the work environment's heat stress. Methods: this review study has systematically reviewed publications and articles from 2000 to 2019 in databases. Keywords including "heat stress”, “heat strain”, “heat exposure”, “heat wave", "heat injuries”, “job accidents”, “job exposure”, “hot environment” and “air change" have been used and finally, 30 articles included into the study. Results: study articles consist of 29 jobs and 1 military environment. Study occupations consist of one study about military forces, textile, aluminum smelting, cleaners of oil reservoirs, two studies about mineworkers and metal and iron industries, three studies about building workers, four studies about agricultural workers and 15 studies about different occupations. Also, 11 studies conducted in open environments, seven studies in closed environments and 12 others conducted both in open and closed environments. 17 analytical studies, three correlational, cross-sectional, cohort studies, one cohort, and descriptive study and two descriptive-analytical studies have been conducted. Most job injuries and accidents happened during summer and men especially the young have involved in such problems and job injuries and accidents have increased due to extreme temperature increase. Generally, job injuries and accidents include burn, slip, collision with things and collision with mobile things. Conclusion: there is a strong relationship between temperature in hot environments and risk increase in injuries and accidents of work environments which differ based on employees' features (such as age, gender, occupation, and industry). However, dominant mechanisms on the happening of such injuries have not been determined yet. It necessitates more expertise to determine especial injuries and accidents happening in hot environments. Policymakers and employers have to be more aware of job injuries and accidents in heat exposure and suitable educational resources have to be provided to prevent such injuries.

Abstract
Background: Physiotherapists (PTs) are at the highest risk of work-related musculoskeletal disorders (WMSDs) because of the nature of demands from their profession. This review aims to describe current knowledge associated with the prevalence and risk factors of WMSDs among Indian PTs. Methods: Various electronic databases were searched for literature relating to WMSDs in PTs from India between years 2010 and 2020. Four full texts and two abstracts were selected based on the inclusion criteria and reviewed in a narrative way. Results: Overall prevalence of WMSDs among PTs was reported to be high, with lifetime prevalence as high as 91%, and the lower back, neck, upper back, and shoulders as the most frequently affected in descending order. The major risk factors reported for WMSDs were: lifting, physical load, transferring, static and awkward static postures, treating a large number of patients per day, and repetitive movements. WMSDs were reported to be associated with age, gender, and physical activity levels, with a higher prevalence in female PTs. Also the younger PTs and PTs with lower physical activity levels were reported to be more affected. Conclusion: It was inferred that the work-related injuries are not prevented by the knowledge about correct body mechanics and skills. PTs need to develop work modification strategies and mechanical aids to reduce WMSDs in without compromising the quality of treatment.

Abstract
Background: Individuals at shooting ranges are exposed to high amount of lead fumes either indoor or outdoor. The shooters sprayed lead dust into the air upon discharge of the cartridge at arm’s length distance. Most of the previous studies conducted at shooting ranges focused on blood lead levels (BLLs) of exposed people and there are limited studies on the risk associated with the shooting of firearms. This study aimed to review previous studies on the hazards associated with the discharge of firearms, and safety measures at shooting ranges. Methods: A systematic review was conducted to explore the available evidence. The databases were searched using the keywords “indoor shooting ranges”, “outdoor shooting ranges”, “firearms shooting”, “lead poisoning hazard”, “blood lead biomarkers”, “permissible exposure limit”, and “safety practice on lead”. Results: The designated BLL for case definition in lead poisoning was between 0.1μg/dL - 0.49μg/dL. It was estimated that at Permissible Exposure Limit (PEL). PEL of 0.5μg/m3, 95 percent of range users who are exposed to lead poisoning regularly can have BLL of <5μg/dL during 20 years of working life, while at 2.1μg/m3, 95 percent of the workers can have BLL of<10μg/dL during their working life. Conclusion: To protect firearm handlers and shooting range workers, policy on preventive measures should be implemented at shooting ranges by policymakers. Compliance with preventive measures is encouraged to avoid the high cost of rehabilitation lead poisoning.

Abstract
Background: In recent years, problems related to environmental damage and natural resource degradation are receiving increased attention from researchers throughout the world. This occurs mostly, through un-eco-friendly technology used to produce industrial products. Therefore, eco-friendly science and technology (green technology) which can empower and control the existing coal power plant for the virtue of society and the earth is required.
Methods: A comprehensive literature search was conducted on Electron Accelerator Applications in Environmental Protection with Emerging Pollutants Decomposing. In this regard, relevant studies were retrieved from the international databases of Scopus, Google Scholar, PubMed, Springer, and Science Direct. The search strategy was developed using keywords such as Electron Accelerator, Flue Gas Treatment, Disinfection, Emerging Pollutants, water, wastewater, degradation and treatment. Finally, 20 articles were selected for detailed review in this study.
Results: The literature addresses various applications of electron accelerators in order to modify the physical, chemical, or biological properties of industrial pollutants in the liquid, solid, and gas phases through treatment by ionizing radiation to control environmental pollution. Many advantages can be achieved through this method, which is known as radiation processing.Conclusion: The electronic beam process in the treatment of off-gas, wastewater, and sludge, as well as the decomposition of emerging contaminants, is mentioned as a non-chemical, additive-free process that uses radiolysis to effectively decompose contaminants.
