The relationship of mercury exposure with neurological problems in artisanal gold in Makassar city

Abstract

AbstractObjectivesThis research aims to analyse the relationship between urine mercury levels and neurological problems.MethodsThis research is an observational study with a cross-sectional approach. There are 44 goldsmiths in the gold jewellery small scale industry involved in this study. Urine mercury levels were measured using an atomic absorption spectrophotometer. Neurological problems were assessed by a medician. Data collected includes age, time of exposure, work duration, smoking behaviour and nutrition status of the goldsmiths which were obtained by interview.ResultsThe results showed that the concentration of mercury in the goldsmith’s urine was around 0.93–64.59 μg/L. The analysis showed that there were 63% of goldsmiths experiencing neurological problems, such as tremors (9.1%) and knee pass reflex (6.8%). The bivariate analysis showed that there is no significant relationship between the concentration of mercury (p=0.133), age (p=0.155), time of exposure (p=0.702), time of working (p=0.354), smoking behaviour (p=0.169) and nutrition status (p=0.541) with neurological problems.ConclusionsThe goldsmiths who had high levels of mercury in urine samples were diagnosed with at least one of the neurological symptoms. It is recommended that the goldsmith use personal protective equipment during work such as mask, glasses and gloves.
