Study of Dioxide Carbon Concentration and Indoor Air Quality in Some Buildings in the Equatorial Region of Cameroon (Yaounde)
Background and purpose: Elevated CO2 rate in a building affect the health of occupant. This document presents results of an experimental analysis conducted in 50 offices located in 12 buildings with different layer in Cameroon (Yaounde). This study took place in 2012, during the dry and the rainy seasons. The main goal is to show the influence of the building structure, the ventilation and the ...
متن کاملEvaluation of a passive air sampler for measuring indoor formaldehyde.
A passive air sampler, using 4-amino-3-hydrazino-5-mercapto-1,2,4-triazole, was evaluated for the determination of formaldehyde in indoor environments. Chromatography paper cleaned using a 3% hydrogen peroxide solution was experimentally determined as being the optimum absorption filter for the collection of formaldehyde (0.05 microg cm(-2) formaldehyde). From a linear-regression analysis betwe...
متن کاملConcentration of Formaldehyde, Acetaldehyde, and Five Volatile Organic Compounds in Indoor Air: The Clean-Healthy House Construction Standard (South Korea)
The authors evaluate indoor air quality in apartments built according to the South Korean Clean-Healthy House construction standard. The evaluation includes three types of residential units with differing gross floor areas. Indoor air was analyzed for formaldehyde (observed range 52.0–99.2 ug/m), acetaldehyde (14.6–61.0 ug/m), benzene (0.6–1.3 ug/m), toluene (161.8–371.0 ug/m) ethylbenzene (6.5...
