Dust monitoring at landfill sites

20 July 2023


The need for monitoring landfill sites:

Landfill sites are known to introduce substantial quantities of pollutants, including dust, gases, odors, and soluble and insoluble substances into the environment. It is crucial to monitor these emissions to ensure compliance with environmental regulations. Landfill activities can generate both fine and coarse particulate matter, depending on on-site operations and the types of waste being handled. These activities include waste movement, handling and processing, plant traffic, and the burning of landfill gas.

Health and environmental impact:

Exposure to dust particles, particularly those smaller than 10 micrometers, can have adverse effects on human health. Concerns arise due to the penetration of these small particles into the respiratory system, potentially causing severe diseases. Dust emitted from landfill sites can become airborne and spread off-site through various mechanisms. The distance traveled by dust particles depends on their size, the wind speed, and turbulence. Larger particles tend to settle closer to the source, while finer particles can travel greater distances. Environmental permits for landfill sites mandate adequate control of dust emissions and require monitoring of particulate matter to safeguard public health and ensure compliance.

The role of Aeroqual’s air quality monitors:

The Dust Sentry Pro, soon to be replaced by the Dust Sentry PCX, is an advanced air quality monitoring system designed for outdoor use. With a robust and weatherproof enclosure, the system maintains optimal performance in challenging environmental conditions. The modular design enables customization based on specific monitoring requirements, offering a flexible and comprehensive solution. Widely embraced by industrial operators, environmental consultants, regulatory authorities, researchers, and health and safety managers, the Dust Sentry Pro reduces stakeholder risks, minimizes on-site time, and provides access to quality data and alerts from any location.

Key features and capabilities:

The Dust Sentry Pro’s software combines a light scattering nephelometer with a sharp-cut cyclone, ensuring highly accurate mass measurement of specific dust particles. It can be configured to measure various parameters, including particulate matter, gaseous pollutants, and environmental factors. The system’s integrated, turnkey approach simplifies data collection, analysis, and reporting, empowering stakeholders to make informed decisions and take timely action.

Next month we are excited to see the Dust Sentry PCX come to market, offering additional mass channels, more precise and reliable measurements, and easier set-up.
