Ambient Air Quality Monitoring India | NABL Accredited

Auriga Research provides NABL-accredited ambient air quality monitoring services across India. Our field teams measure all NAAQS-prescribed pollutants including PM2.5, PM10, SO2, NO2, CO, ozone, lead, ammonia, benzene, and benzo(a)pyrene using calibrated high-volume samplers and continuous monitoring equipment per CPCB guidelines.

Services cover EIA baseline air quality studies, industrial compliance monitoring, consent condition verification, and urban air quality assessments. All reports are structured for direct submission to SPCB, MoEFCC, and EIA consultants.

Air Quality Parameters

PM2.5 and PM10 — gravimetric analysis per IS 5182
SO2 — improved West and Gaeke method
NO2 — modified Jacob and Hochheiser method
CO — non-dispersive infrared analyser
Ozone (O3) — UV photometric method
VOCs (benzene, toluene, xylene) — GC-FID/GC-MS
Heavy metals (Pb, As, Ni) — ICP-MS after acid digestion
Ammonia (NH3) — indophenol blue method
Benzo(a)pyrene — HPLC with fluorescence detection

Who Needs Air Quality Monitoring

Industries requiring SPCB consent compliance monitoring
EIA consultants conducting baseline environmental assessments
Mining and thermal power projects per MoEFCC conditions
Urban local bodies and smart city projects
Real estate developers near industrial zones

Turnaround Time

Field sampling takes 24-48 hours per location. Laboratory analysis and reporting are completed within 12-15 business days of field sampling. Expedited reporting is available for urgent compliance submissions.

Frequently Asked Questions

What pollutants are covered under ambient air quality monitoring?

Our ambient air quality monitoring covers all NAAQS (National Ambient Air Quality Standards) parameters: PM2.5, PM10, SO2, NO2, CO, O3, lead, ammonia, benzene, benzo(a)pyrene, and arsenic/nickel. For industrial EIA studies, we additionally monitor VOCs (volatile organic compounds), H2S, and site-specific pollutants based on the nature of the industrial process.

How is ambient air quality sampling conducted in the field?

We deploy high-volume samplers (respirable dust samplers) and fine particulate samplers for PM2.5 and PM10 collection on pre-weighed filters. Gaseous pollutants are sampled using impingers with specific absorbing solutions or continuous analysers. Sampling is performed over 24-hour averaging periods at locations determined per CPCB siting criteria — upwind, downwind, and at sensitive receptors.

What is the turnaround time for ambient air quality monitoring reports?

Field sampling for a single monitoring location takes 24-48 hours per session. Laboratory analysis of collected samples takes 7-10 business days. A complete ambient air quality monitoring report — including data analysis, comparison with NAAQS, and wind rose interpretation — is delivered within 12-15 business days of field sampling completion.
