An analysis of our water and air composition
is now possible, as is real-time tracking of traffic.
The airflow with an increased C[O.sub.2] and a decreased [O.sub.2] mass concentration passes through the leaves and changes the air composition
. Thus, the concentration of C[O.sub.2] is going down, whereas the concentration of [O.sub.2] is going up.
For the latest study, researchers measured the air composition
in a non-smoking, unoccupied classroom over the course of a month using an aerosol mass spectrometer.
They also look at the structure and composition of fossils to determine information about air composition
and the presence of diseases.
Emmanuel told the mayor that Belgium used to enjoy better air quality before the facility was put up, 'but, in the months following its operation, there were changes in the air composition
, suspecting the particles to have come from the facility.'
Finish performance was found to be strongly dependent on environmental variables, such as chemical air composition
, temperature, humidity and laminar airflow rates.
The air composition
of underground environment in the Cacica and Ocna Dej salt mines were determined with RAE gas detection tubes and the following gases and volatile compounds were assayed: O2 (%), CO2 (%), CO (ppmv), SO2 (ppmv), O3 (ppmv), Cl2 (ppmv), NH3 (ppmv), NOX (ppmv), HC (ppmv), H2O (mg/L).
It said a web browser or search engine located at the user's site might obtain information on the environment, such as temperature, humidity, light, sound, air composition
, from sensors.
The company's approach is to identify small variations in the air composition
within an arm-length to the driver's mouth and nose.
Sensors that measure temperature and air composition
can also be distributed.
