Black Carbon Monitoring System




Black Carbon Monitoring System


A Black Carbon Monitoring System is used to measure black carbon (BC)—a major component of air pollution produced by incomplete combustion (diesel engines, biomass burning, industrial emissions). It’s important because black carbon impacts climate change and human health.

Key Technologies Used

Aethalometer

Real-time BC measurement

Uses multiple wavelengths

Multi-Angle Absorption Photometer (MAAP)

More accurate in complex environments

Thermal-Optical Analysis

Used in labs for detailed carbon speciation

Frequently Asked Questions

Black carbon is a fine particulate (part of PM2.5) that:
Absorbs sunlight and heats the atmosphere
Contributes to glacier melt
Causes respiratory and cardiovascular issues

Air Sampling
Ambient air is continuously drawn into the device

Particle Collection
Particles deposit on a filter (usually quartz or fiber)

Optical Measurement
Light absorption is measured to estimate BC concentration
Based on the principle of Light Absorption

Black carbon monitoring helps:
Shape environmental policy
Improve urban air quality
Track climate impact
Protect public health
