Abstract: OBJECTIVE: To compare serum immunoglobulin contents among different populations of residents in the downwind direction of a coking plant from 2015 to 2019 and to analyze changes in trends of abnormal rates. METHODS: In each summer from 2015 to 2019,residents from two villages in the downwind direction (1 to 2 km) of a coking plant in northern China were selected as the research group. They were recruited according to certain inclusion and exclusion criteria,and their blood and urine samples were collected to detect the contents of immunoglobulin (IgG,IgA and IgM) and urine creatinine (Cr) through an automatic biochemical analyzer. Abnormal rates of serum immunoglobulin contents were statistically analyzed. Contents of polycyclic aromatic hydrocarbon metabolite 1-hydroxypyrene in urine was detected by high performance liquid chromatography-fluorescence detection method. RESULTS: Among the research residents, the average serum IgG contents in women were higher than that of men for each year (P<0.01),and the average IgM contents were higher than that of men in 2015 and 2016 (P<0.05); The average serum IgG and IgA contents of adults were higher than those of minors in each year (P<0.01),while the average serum IgM content of adults was lower than that of minors in 2016 (P<0.01). In 2015-2019,the abnormal rates of serum immunoglobulin contents showed an overall upward trend and then a downward trend. There were significant differences in serum IgA and IgM between different years (P<0.01). And in 2016,the abnormal rates of serum IgG,IgA and IgM contents in adult were higher than those in minors (P<0.05). The abnormal rates of serum IgG contents in women were higher than that in men in 2015 and 2016 (P<0.05). In addition,from 2015 to 2019,the median detection levels of polycyclic aromatic hydrocarbon metabolite 1-hydroxypyrene in the urine of residents in this area were 0.468,0.797,0.678,0.169 and 0.021 μg/g,respectively. CONCLUSION: From 2015 to 2019,the serum immunoglobulin (IgG,IgA and IgM) levels of residents in the downwind direction of the coking plant showed certain gender and age differences,and their abnormal rates generally show an upward trend and then a downward trend.
