Abstract: Objective To explore the association between low blood lead exposure and nervous system symptoms among the workers exposed to oil paint.Methods Through cluster sampling,workers with occupational oil paint exposure in 2 factories were selected to conduct a questionnaire survey,biochemical detection and health examination.x2 test and unconditional logistic regression analysis were performed for the determinants analysis.Results A total of 525 oil paint workers completed the survey,in whom,55 (10.5％) were blood lead positive,the mean of blood lead concentration was (0.088 4 ± 0.053 9) mg/L,278 (52.95％) had nervous system like symptoms and 69 (13.14％) had peripheral neuropathy symptoms.Multinomial logistic regression analysis showed that working age (OR=1.827),drinking (OR=1.607),health status (OR=3.862),blood lead (OR=1.983) were risk factors for nervous system like symptoms.Working age (OR=2.282),and drinking (OR=2.704) were risk factors for peripheral neuropathy.Conclusion Low blood lead exposure might be associated with nervous system like symptoms.
