NAAQS India Lead Concentration Standard
The National Ambient Air Quality Standards (NAAQS) in India specify permissible concentrations of pollutants in ambient air. These standards vary based on the area type (e.g., industrial, residential) and averaging time.
For lead (Pb) in an industrial area, the NAAQS mandates a maximum permissible 24-hour average concentration.
The specified limit is 1.0 $\mu$g/m$^3$.
