Risk of Neurotoxic Symptoms among Motorcycle Workshop Workers in Surabaya: A Cross-Sectional Study

Abstract

This study analyzed the risk of neurotoxic symptoms among motorcycle workshop workers in Surabaya due to exposure to hazardous chemicals such as organic solvents, heavy metals, and particulate matter. The study used an analytical observational design with a cross-sectional approach involving 32 workshop workers and applied the validated German version of the Q18 questionnaire. The results showed that 28.12% of respondents experienced positive neurotoxic symptoms, with the most frequently reported complaints being excessive sweating (75%), fatigue in the hands and feet (68.75%), palpitations (56.25%), and difficulty concentrating (28.12%). Most respondents were male, aged 26–45 years, had a working period of less than 10 years, and were nonsmokers.These findings indicate a tangible risk of neurotoxic disorders among motorcycle workshop workers, highlighting the need for control measures such as improved ventilation, proper use of personal protective equipment (PPE), regular
health examinations, and occupational health and safety education. Further studies with larger sample sizes and biomonitoring methods are recommended.
