Occupational exposure to BTEX and styrene in West Asian countries: a brief review of current state and limits.

The aim of introducing occupational exposure limits (OELs) is to use them as a risk management tool in order to protect workers' health and well-being against harmful agents at the workplace. In this review we identify OELs for benzene, toluene, ethylbenzene, xylene (BTEX), and styrene concentrations in air and assess occupational exposure to these compounds through a systematic literature search of publications published in West Asian countries from 1980 to 2021. OELs for BTEX and styrene have been set in Iran and Turkey to levels similar to those in European countries and the US.

Effect of occupational exposure to lead on serum levels of lipid profile and liver enzymes: An occupational cohort study.

The present study was performed to know the effects of chronic lead exposure on serum lipids, lipoproteins, and liver enzymes in a cohort study among of lead mine workers. We followed of 200 Iranian workers for 3- years (2018-2020), 100 of them with known occupational exposure to lead thorough their work in lead mine while the others 100 were with no such exposure. Blood lead level (BLL), serum lipids, lipoproteins, and liver enzymes of the exposure group for 3- years were measured and compared with those attained in the non-exposed workers.

Evaluation of occupational noise exposure and general health of workers in industrial sites: A case study.

Background: Occupational noise exposure in workplaces is the most common detrimental factor that has the greatest impact on the health of people working there.

Objective: The aim of this study was to evaluate occupational noise exposure and its relation to the general health status in industrial workers in Sanandaj, Iran.

Methods: This cross-sectional study was conducted on the general health of 500 male workers in Sanandaj using the General Health Questionnaire (GHQ-28).

Risk Assessment of Workers' Exposure to Volatile Organic Compounds in the Air of a Petrochemical Complex in Iran.

Context: Long-term exposure to volatile organic compounds (VOCs) affects the occupancies health in petrochemical complex.

Objectives: The aim of this study is to apply the lifetime cancer risk (LCR) and hazard quotient (HQ) in occupational exposure to estimate the risk of VOCs in petrochemical complexes.

Settings And Design: A cross-sectional study was conducted in the petrochemical complex of Iran for a period of 1 year.

The effect of Base Transceiver Station waves on some immunological and hematological factors in exposed persons.

Background: Since the number of mobile subscribers has significantly increased in recent years, the installation and deployment of Base Transceiver Station (BTS) antennas sending and receiving signals has become common and inevitable in different regions.

Objective: In this study, we have tried to evaluate the effect of the waves on some immunological and hematological parameters in exposed individuals. In this study, the exposed and non-exposed individuals were used as the test and control groups, respectively.
