Below is the professionally structured list of METS environmental monitoring capabilities, aligned with international regulatory standards.

A. Ambient Air Quality Monitoring

We perform high-precision monitoring of ambient (outdoor) air pollutants using advanced real-time analyzers and reference laboratory techniques.

Pollutants Monitored

• PM₁₀ / PM₂.₅
• SO₂
• NO, NO₂, NOx
• CO
• O₃
• VOCs
• BTX
• Heavy Metals

Applicable Standards

• AS/NZS 3580.12.1
• AS 3580.5.1
• AS 3580.4.1
• AS 3580.7.1
• AS 3580.6.1
• BS EN 60079-29-2
• EPA-454/R-99-005
• ISO 21501-4
• OSHA Technical Manual (OTM), Section III

These standards ensure accurate detection of pollutants and compliance with environmental regulatory frameworks.

B. Noise Monitoring (Environmental & Occupational)

Parameters Measured

• Lₑq (Equivalent Continuous Noise Level)
• Lₘₐₓ / Lₘᵢₙ
• L_dn (Day-Night Noise Levels)
• L_peak (Impulse Noise)

METS also provides Personnel Noise Exposure Monitoring using calibrated noise dosimeters to measure individual worker exposure.

Standards Followed

• OSHA 29 CFR 1910.95
• NIOSH RELs
• ISO 9612
• Local regulatory requirements

These assessments help determine worker safety compliance and noise mitigation requirements.

C. Stack Emission Monitoring

We conduct U.S. EPA-approved stack emission testing for industrial air pollutants using Direct Sensor Readout instrumentation (Lancom III).

Key Pollutants Measured

• PM
• VOCs
• SOₓ
• NOₓ
• CO
• Heavy metals
• Moisture

Applicable Standards

• USEPA CTM-030 / CTM-034
• USEPA Method 10 (CO)
• USEPA Method 6C (SO₂)
• USEPA Method 1 & 2 (Velocity traverses)
• USEPA Method 5 (PM)
• USEPA Method 4 (Moisture)

These methods provide legally defensible and regulator-approved emission data.

D. Lux (Illuminance) Monitoring

We measure workplace lighting using fully calibrated digital lux meters to ensure compliance with occupational and visual comfort standards.

Standard Followed

• BS 667:2005

Used for:

• Lighting compliance audits
• Worker ergonomics evaluations
• Energy and illumination optimization

E. Heat Stress Monitoring

Our heat stress assessments follow the OSHA Technical Manual (2017) and ISO/ACGIH guidelines.

Parameters Evaluated

• Dry Bulb Temperature (DBT)
• Wet Bulb Temperature (WBT)
• Globe Temperature
• Relative Humidity
• Air Velocity
• Heat Index
• WBGT (Wet Bulb Globe Temperature) — Indoor & outdoor metrics

This helps organizations maintain worker safety in extreme-temperature environments.

F. Dioxins & Furans Testing

We perform ultra-trace analysis of dioxins and furans in ambient air and stack emissions using:

Analytical Technique

• HRGC–HRMS (High-Resolution Gas Chromatography – High-Resolution Mass Spectrometry)

Regulatory Standards

• EU Directive 2010/75/EU
• USEPA Method 23 / TO-9A
• Stockholm Convention on POPs

Our testing provides pg/Nm³-level sensitivity required for regulatory compliance.

G. Environmental Microbial Monitoring (Air, Surface, Personnel)

Essential for pharmaceuticals, biotech, healthcare, cleanrooms, laboratories.

Air Monitoring

• Passive settling plates
• Active air sampling (precision microbial quantification)

Surface Monitoring

• Contact plates
• Swab tests

Personnel Hygiene Monitoring

• Gloves
• Garments
• Fingertips

Benefits

• Validates aseptic conditions
• Ensures GMP/ISO compliance
• Prevents contamination
• Protects product quality and patient safety
