Vehicles are one of the chief sources of heavy metal pollution in the environment via processes like the exhaust of diesel and petrol, corrosion of metallic parts, engine wear, tyre and brake pad wear. Heavy metals can accumulate in organisms, plants, or animals (including humans) through inhalation. Some heavy metals can be toxic at a low level of exposure and cause carcinogenicity in humans.

How SIG can  help

SIG laboratory performs analysis of heavy metals on a wide variety of matrices.

The types of heavy metals that can be tested in the SIG laboratory are:

• Mercury (Hg)
• Lead (Pb)
• Cadmium (Cd)
• Hexavalent Chromium

Method of Analysis

ICP-OES and ICP-MS techniques are the most frequently used, along with classical atomic absorption spectroscopy (AAS) with Hydride Vapor Generator (HVG).
