Morocco: ENVEA provides AQMS Stations in Support of National Air Program - Case Study

According to a national study conducted in 2014, the cost of air quality deterioration in Morocco was estimated at 9.7 billion dirhams equivalent to 1.05% of GDP, recording a notable increase compared to the year 2000. The industrial sector, including the fossil fuel sector, has experienced significant growth. Transport has also developed with the sustained increase in the ...

What is Ambient Air Quality?

The Earth’s atmosphere is divided into five major layers: namely, the troposphere, stratosphere, mesosphere, thermosphere, and the exosphere. The troposphere is the atmospheric layer closest to ...

What are ultrafine particles, and how can you include size distributions and concentrations as part of routine air quality monitoring?

Ultrafine particles (UFP) are particles that are too small to contribute appreciably to mass-based measurements, but are present in ambient air. While regulations focus on PM and neglect ultrafine particle number concentrations, a growing body of ...
