The importance of monitoring and evaluating indoor air quality in buildings is because, these days, people spend more and more time inside buildings (housing, employment, services, leisure) being thus exposed to the action of pollutants, related materials used in the construction and maintenance, with HVAC systems, with the occupants and the outdoor air quality. In this context the EQS Global performs according to the standards and current applicable legislation in the assessment of indoor air quality by measuring the main following parameters:

• Particles
• Volatile organic compounds
• Carbon monoxide (CO)
• Carbon dioxide (CO2)
• Formaldehyde (HCHO)
• Ozone (O3)
• Microbiological (bacteria, fungi and legionella)
• Radon (Rn)

The assessment of outdoor air quality is an evaluation of the outdoor ambient air by measuring according to the standards and current applicable legislation of the main following parameters:

• Particles suspended in the atmosphere fraction PM10
• Particles suspended in the atmosphere fraction PM2,5
• Atmospheric concentrations of sulfur dioxide
• Atmospheric concentrations of carbon monoxide
• Atmospheric concentrations of nitrogen oxides
• Atmospheric concentrations of ozone

The testing of stack emissions in stationary sources is testing that evaluates the emission of several parameters into the atmosphere. The main parameters that are evaluated are:

• Flow parameters (speed, flow rate, humidity, temperature, and pressure)
• Particles
• Sulfur dioxide (SO2)
• Nitrogen oxides (NOx)
• Carbon monoxide (CO)
• Hydrogen sulfide (H2S)
• Heavy metals
• Volatile Organic Compounds (VOCs)

The monitoring is performed according to the standards and current applicable legislation.
