Abstract

Xylene is the most dominant substance in spray painting in the automotive industry. Some studies showed that xylene can cause health problems, one of which is a neurological symptoms.This study was conducted in one area of car painting on Jalan Pengenal, Surabaya. The aim of this study was to analyze the relationship of levels of xylene in blood with neurological symptoms on car painting workers in Pengenal Street, Surabaya. This study was designed as an observational study and conducted by cross sectional method. Samples were obtained by using stratified random sampling technique were 51 painters. The dependent variable in this study was neurological symptoms which were meant by German version of the Q18 questionnaire, while the independent variables were characteristics of workers (age, exercise habits, body mass index, respiration rate, the habit of using personal protective equipment, smoking), xylene levels in the blood, which was measured by ELISA, and occupational factors (working period, duration of work and job description). This research showed that levels of xylene of work environment in two out of five workshops were 271 ppm and 341 ppm respectively higher than threshold limit value (TLV), 100 ppm. The results of Pearson correlation analysis showed a significant correlation on age, period of working, and duration of working, and Spearman correlation analysis showed that habit of using PPE mask, smoking habits, and xylene levels in the blood,where probability is smaller than p-value 0,05, which strongly considered have a strong association with neurological symptoms on workers. Based on simple linear regression analysis showed that correlation coefficient (R-square) was 0.718, which means PPE masks and xylene levels in the blood were able to explain the value of neurologic symptoms amounted to 71.8% and 28.2% were influenced by other factors. It is concluded that blood levels of xylene is related to neurological symptoms in informal car painters. Relationship of xylene exposure with neurological symptoms reveals by monitoring levels of xylene in blood and habitual use of PPE masks. In advance, as suggestion for owner is to substitute organic compound safer than xylene and always provide suitable PPE mask for workers during work time.
