DEVELOPMENT OF SENSITIVE PASSIVE SAMPLER FOR NITROGEN DIOXIDE AIR POLLUTION MONITORING
(Soc Brasileira Quimica, 2017-10-01)
A passive sampler constructed with a new type of material and used for measurement of ambient nitrogen dioxide is presented. The sampler was constructed with parts of two 50 mL conical centrifuge tubes. The procedure is ...
Assessing polychlorinated dibenzo- p -dioxins and polychlorinated dibenzofurans in air across latin american countries using polyurethane foam disk passive air samplers
(American Chemical Society, 2015-03)
A passive air sampling network has been established to investigate polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) at Global Atmospheric Passive Sampling (GAPS) sites and six additional ...
A field evaluation of a SO2 passive sampler in tropical industrial and urban air
(Elsevier, 2004-12)
A Simple Technique Based on Digital Images for Determination of Nitrogen Dioxide in Ambient Air
(2021-02-01)
The lockdown to prevent the coronavirus spread resulted in an immediate reduction in gas concentration worldwide. This fact shows the importance of nitrogen dioxide as a pollutant gas directly associated with human activities. ...
A field evaluation of a SO2 passive sampler in tropical industrial and urban air
(Elsevier, 2004)
Passive samplers have been widely used for over 30 years in the measurement of personal exposure to vapours and gases in the workplace. These samplers have just recently been applied in the monitoring of ambient air, which ...
Construção de amostrador passivo de baixo custo para determinação de dióxido de nitrogênio
(Sociedade Brasileira de Química, 2006-04-01)
A new passive sampling system for monitoring NO2 in air has been developed to measure gas concentrations in indoor and outdoor air. The sampler is inexpensive, and easy to construct and operate. Nitrogen dioxide forms a ...
