BQCIS

Integrated Monitoring of Ambient and Stack Emissions

BQCIS delivers accredited air monitoring services covering both fixed-source (stack) emissions and ambient air quality measurements to meet regulatory and environmental management objectives. Testing is performed under ISO 4225, EPA TO-15, EN 15267, and ISO 10155 standards for industrial, power generation, and environmental compliance.

Using continuous emission monitoring systems (CEMS), portable analyzers, and high-precision sampling instruments, we quantify major pollutants such as PM₂.₅, PM₁₀, SO₂, NOₓ, CO, CO₂, CH₄, VOCs, and NH₃. Data supports emission inventories, environmental impact assessments, and operational optimization.

Our laboratories and field engineers ensure traceable calibration, QA/QC validation, and comprehensive reporting — helping industries demonstrate environmental stewardship and compliance with national emission regulations and international frameworks such as ISO 14001.

Key Activities in Air Quality & Emission Monitoring

Stack Emission Sampling

Isokinetic sampling of particulates and gases from industrial stacks following ISO 9096 and EPA Method 5 standards.

Continuous Emission Monitoring (CEMS)

Real-time monitoring of SO₂, NOₓ, CO, CO₂, and O₂ concentrations using certified EN 15267 instruments.

Ambient Air Monitoring

Measurement of PM₂.₅, PM₁₀, ozone, VOCs, and NO₂ using reference-grade analyzers and passive samplers.

VOC & Odor Analysis

GC-MS and EPA TO-15 analysis of volatile organic compounds and odor-causing substances in air matrices.

Greenhouse Gas Quantification

Monitoring of CO₂, CH₄, and N₂O emissions for carbon inventory and sustainability reporting.

Workplace Air Sampling

Occupational exposure monitoring per OSHA and NIOSH methods to ensure worker safety and compliance.

Calibration & QA/QC Verification

Routine calibration, leak tests, and validation checks ensuring traceable and defensible measurement data.

Emission Inventory & Compliance Reporting

Preparation of emission summaries, exceedance analysis, and compliance documentation for regulatory authorities.

Dispersion Modeling Support

Providing high-quality emissions data to support air dispersion modeling for environmental impact assessments.

Key Benefits of Air Quality & Emission Monitoring

Demonstrate conformity with ISO, EPA, and EN emission limits and environmental permits.

Operational Optimization

Operational Optimization

Identify inefficiencies and emission hotspots for energy saving and cleaner production.

Environmental Protection

Environmental Protection

Monitor and reduce air pollution impacts on communities and ecosystems.

Traceable Reporting

Traceable Reporting

Defensible, accredited data with calibration certificates and chain-of-custody assurance.

Success Story

Emission Compliance Program for Cement Manufacturing Plant

The Challenge:

A major cement producer required third-party stack and ambient air monitoring to comply with new national emission standards and renew ISO 14001 certification.

Our Solution:

BQCIS implemented a two-phase program involving isokinetic stack testing, VOC analysis, and ambient PM₂.₅/NOₓ monitoring using EN 15267-certified analyzers.

The Result:

All emission values were within regulatory limits. Data submission supported compliance renewal and improved operational efficiency by 12% through combustion optimization.
