The heavy metal and isocyanate content of both paints and primers were analyzed using Atomic Absorption Spectroscopy (AAS) and Gas Chromatography-Mass Spectrometry methods respectively. The analysis revealed that manganese and chromium concentrations in some paint samples exceeded permissible limits, while lead levels were significantly higher than the European Union's (EU) safety threshold. Conversely, cadmium, mercury, aluminium, copper, iron, nickel, arsenic, and cobalt were within acceptable regulatory limits. In primers, zinc concentrations were found to be above the EU limit, whereas other heavy metals remained below recommended levels. Additionally, all analyzed paint and primer samples contained isocyanate concentrations far exceeding the Occupational Safety and Health Administration (OSHA) exposure limit of 0.02 ppm, posing potential health risks to workers. These findings underscore the need for regulatory oversight, the adoption of safer alternatives, and enhanced protective measures to mitigate health hazards associated with automobile spray painting.
