To estimate the effects of aerosols on health and climate, it is essential to know their chemical composition. Sampling is done using two different types of aerosol collector. The first type are filter collectors that are based on the deposition of suspended particles on surfaces; the second type are powerful aerosol collectors.

Many of the air quality analyses can be performed with standard laboratory consumables, such as traditional filter papers. However, some analyses require materials with specific features, for example filters with low metal levels.
Common air monitoring applications include:
- Air quality testing of ambient environment and emissions. Includes particulate monitoring methods such as PM2.5 and PM10, and chemical analysis such as heavy metals determination.
- Asbestos sampling and analysis

Context & Challenges Globally, the wastewater treatment is the first public health issue. Urban development leads to urbanization near waste water treatment plant and extension of sewerage network. These aspects induce to an augmentation of sulfur compounds (H2S, mercaptans and sulfides) which are very corrosive, odorant and toxic. To monitor this compounds online CHROMATOTEC® offers high meteorological solutions. As a result of the confinement of the waste water stations, toxic components such as H2S...
