A significant uptick in chronic benzene poisoning among Chinese workers has been identified, highlighting pressing occupational health concerns. Spanning from 2005 to 2019, data reveals patterns and shifts in industries and enterprise sizes where benzene exposure is prevalent.
Rising Number of Affected Workers
Analysis of 176 reported cases from the Sichuan Center for Disease Control and Prevention indicates a clear increase in benzene poisoning incidents as the years progress. The study’s linear regression demonstrates a positive correlation between the number of workers and time, emphasizing growing occupational hazards.
Shifting Industry and Enterprise Dynamics
Initially concentrated in joint-stock enterprises and equipment manufacturing, benzene poisoning cases from 2017 to 2019 show a significant rise in private and light industries. Moreover, medium and large-sized enterprises dominate the affected sectors, suggesting that company size plays a role in exposure risks.
- Gender distribution remains balanced, with no major differences in age or exposure duration between males and females.
- Despite a decline in working duration, the trend lacks statistical significance, indicating potential variability in exposure periods.
To safeguard workers’ health, it is essential to enhance benzene concentration monitoring across workplaces and implement targeted preventive strategies. Understanding the evolving industry landscape and enterprise sizes can aid in designing effective interventions tailored to specific sectors, thereby mitigating the risk of chronic benzene poisoning.
