Abstract
Exposure to chemical hazardous at car spray workshop will lead painter to be exposed to lead, cadmium and copper. Such exposure can cause adverse health effects to car painters due to neglect of regulation and guidance of safety and health. This study was
aimed to assess the risk level of lead, cadmium and copper among car paint worker in
Kota Bharu. 13 subjects for exposed group and non-exposed were selected from spray
painter at car and in Campus Universiti Sains Malaysia (USM) respectively .Urine
samples were collected at the post-shift work for both exposed group and for nonexposed
group. They were asked to answer questionnaire related to their work. Urine
sample of exposed and non-exposed group were digested with Nitric Acid (HNO3),
Hydrochloric Acid (HCI) and Hydrogen Peroxide (H2O2) and lead, cadmium and
copper were analyzed by using the Atomic Absorption Spectrometer (AAS)-Perkin
Elmer Analyst 800 to measure the level of concentration. Factors socio-demographic
such as smoking, duration of exposure to chemicals, duration of employment, and
intake of seafood and alcohol can cause presence of lead, cadmium and copper present
in urine. In conclusion, lead, cadmium and copper concentration levels in urine can
detect the presence of lead, cadmium and copper among exposed and non-exposed
groups.
