Abstract

Summary: Introduction: Pesticides are used in varying amounts on crops in the agriculture sectors. This cross sectional study was conducted in oil palm (FELDA) plantation, Johor. Objective: The main objective is to determine the association between pesticide exposure level and the neurobehavioral performance among pesticide handlers working in FELDA plantation in Johor. Methods: This study was conducted during the period of pesticides applied to the palm oil tree. Purposive sampling was used to select the respondents based on the inclusion criteria such as male workers, and must be literate. There were 51 male pesticide handlers (exposed group) exposed to Paraquat and 51 male harvesters (non-exposed group) were selected to participate in this study. Questionnaire was administered in determining demographic, working characteristics, exposure history and health status. All respondents completed the 7 tests of neurobehavioral core test battery (NCTB) (verbal abstraction, attention, memory, and visualmotor speed). Field observation of exposed group was performed to determine the exposure rating (ER) based on chemical health risk assessment (CHRA) method. Results: The result showed the neurobehavioral performance score for exposed group and non-exposed group of oil palm plantation in Johor has no significant different (p > 0.05). Working factors such as exposure rating (ER) and years of employment has significant relationship (p < 0.05) with NCTB test. Exposure rating and smoking were found to be the factors that influence the total NCTB score based on multiple regression analysis. Conclusions: Evidence from this study suggests that working factors of pesticide handlers were associated with neurological impairment due to pesticide exposure. Keywords: Neurobehavioral core test battery (NCTB), Paraquat, Pesticide handlers, Exposure rating
