Volume 2, Issue 2 (16 2009)
Abstract

Backgrounds and Objectives: Noise in large cities is considered by the World Health Organization to be the third most hazardous type of pollution. Buses are an interesting object of study in the theme of noise pollution. They are at the same time a source of urban environmental (traffic) noise and occupational noise exposure source for drivers. The object of this study is Occupational noise exposure evaluation in drivers of bus transportation of Tehran city.
Materials and Methods: Noise levels in 90 buses were sampled in three separate sub-sample including (1)30 Ikaroos buses (2)30 Man buses (3)30 Shahab buses, which were selected by simple random sampling. Noise exposure level was normalized to a nominal 8-h working day (LEX, 8h). Simultaneous Octave Frequency Analysis were measured and sound intensity level (SIL) for bus drivers were calculated. Results, which are obtained from separate buses were compared together and too with standard levels.
Results: the normalized noise exposure levels (LEX, 8h) in Ikaroos bus drivers(82dB A) were higher than that of in in Man bus drivers (77/6dB A) and this Values were higher than that of in Shahab bus drivers(75dB A).SIL values for Ikaroos bus drivers were higher than other that of other bus drivers. Results obtained of Frequency Analysis showed that age of buses in mid frequencies ws a meaningful on noise increase.
Conclusion: Results showed that type and age of buses were effective factors in drivers. noise exposure levels (LEX, 8h), which was consistent with previous studies in this field.

Volume 6, Issue 1 (5-2013)
Abstract
Background and Objectives: Microorganisms are the agents that can cause disruption in the biochemical and physiological reactions through mechanisms such as infection, allergy or toxic properties in the case of entering human body and if the body’s immune system be unable to destroy and eliminate biological agents, illness and even death will occur. This study evaluates air pollution (aerosol and bioaerosol) in different parts of a hospital in Tehran.
Materials and Methods: We assessed and evaluated bioaerosols by applying 0800 NIOSH method using Bacterial sampler and specific cultures for bacteria and fungi separately in ICU (intensive care unit), Pathology laboratory, Operating room, Recovery, and CSR (Central Service Room) of a hospital.
Results: The assessment showed that the average density of bacteria in the hospital studied was in the range of 1226.88 - 294.47 CFU/m3 the highest density was observed in the CSR and the lowest density measured was in the operating room. The bacteria identified included gram-positive bacillus (50.6%), Staphylococcus epidermis (20.29%), Staphylococcus Saprophyticus (2.6%), Staphylococcus aureus (7.03%), other Staphylococcus (5.9%) and Micrococcus (13.43%). Moreover, it was found that the average density of fungi was in the range of 0-188.45 CFU/m3 the maximum density in ICU and the minimum density in operating room and recovery room. The fungi identified included Aspergillus flavus (31.65%), Aspergillus fomigatus (25.17%), Aspergillus niger (15.82%), and penicilliom (27.33%) .
Conclusion: Comparison of bacteria density in different parts of the hospital with the recommended limits of ACGIH (500 CFU/m3) showed that density exceeded the limits in all units except in operating room whereas, density of fungi was less than the recommended limits of ACGIH (100 CFU/m3) in all units of hospital.

Abstract
Background and Objective: Compliance with the principles of food safety and hygiene is very important in the entire chain of production, storage, transportation and supply of food to ensure the safety and suitability of food to ensure the health of consumers. Therefore, a study was conducted to determine the status of indicators and prerequisite programs for health and food safety in the fruit and vegetable fields of Tehran in 2022.
Materials and Methods: A descriptive-analytical study on 67 fruit and vegetable centers in Tehran city regarding the status of indicators and prerequisite programs for food safety and hygiene, such as the condition of buildings and facilities, employee training, employee health, food quality control, control of environmental pests, waste disposal and work environment hygiene were done. First, a questionnaire was prepared and its validity was confirmed by the opinion of five experts, as well as its reliability tool with Cronbach's alpha coefficient of 0.87, then the questionnaire was completed and the necessary data was recorded. The data were statistically analyzed using SPSS software.
Results: The results showed that the favorable condition of buildings and facilities, employee education, employee health, food quality control, environmental pest control, waste disposal and workplace hygiene were 67.16%, 26.85%, 50.20%,67.91%, 43.65%, 58.39% and 63.11%, respectively. So the indicators of building and facilities, food quality control, food consumption and work environment with an average of more than a percentage are acceptable. However, the indicators of care education and combating environmental chastity have been evaluated as unfavorable
Conclusion: Knowing the status of indicators and prerequisite programs for food safety and hygiene in the fruit and vegetable fields of Tehran city can help to improve food safety and health. Also, the desirability of indicators of buildings and facilities, food quality control, waste disposal and workplace hygiene affect the supply and distribution of healthy food. It is also recommended to pay more attention to raising the level of education in the care and methods of environmental pest control in fruit and vegetable fields.
