Abstract

The present study aims to analyse the effects of lead (Pb) chronic exposure on blood lead levels, Monoamine oxidase\ud A enzyme (MAO A) and serotonin levels of brass craftsmen in Pati, Central Java, Indonesia, and to examine the connections\ud among these three variables. The brass home industry area was polluted by lead. Thus, it chronically exposes the workers to\ud lead pollution. Therefore, their blood lead level increased and later raised the level of MAO A and reduced the level of serotonin.\ud Path analysis results show that the path coefficient (ñ) of lead effects in decreasing serotonin through MAO A pathway is\ud -0.411. Furthermore, lead effects that directly affect serotonin level without passing through MAO A pathway is -0.391 with\ud residual coefficient (e) of 0.572. In conclusion, the increase of blood lead level causes an increase in level of MAO A and\ud drop in the level of serotonin
