Abstract:
Objective To observe the effect of atmospheric pollution on workers'α1-antitrypsin concentrationb in petrochemical enterprises.Methods During health examination,the workers were indivded into 3 groups according tO the length of job experience.Ⅰ group(<10 years)included 291 cases,aged 22-35 years old,Ⅱ group(10-20 years)included 634 cases,aged 33-45 years old,and Ⅲgroup(>20 years)included 427 cases,aged 44-55 years old.The normal control were individed int different group according to the status of petrochemical workers.,all the serum samples were detected on automatic biochemical analyzer,α1-antitrypsin levels were analyzed between the different groups.Results In group Ⅰ,the α1-AT concentration was 2.58±0.38 g/L(P>0.05)without significant difference compared with control.In group Ⅱ and Ⅲ,the concentration α1-AT were 2.02±0.43 g/L and 1.72±0.41 g/L respectively with significant differences compared with control.And the significant difference existed among the three groups of petrochemical workers..But the sigficant difference did not exist between different group of control people.Conclusion During the process of oil refining,the plants exhausted the polluted gas of nitrogen dioxide,olefins,alkanes,alcohols,carbonyl and other harmful substances,it influenced theα-AT levels of body.It is a good suggestion to decreas the petrochemical pollution,and to monitor the serum concentration of α-AT content among petrochemical workers,it might to reduce the incidence of lung disease of great significance.
