Scope
This variable describes the indoor air PM 2.5 concentration in Finland originating from indoor sources, such as environmental tobacco smoke (ETS), cooking and wood stove combustion.
Definition
Data
Description of the data used for obtaining the value of the variable (e.g. measurement data; mathematical method and its parameters).
Please include references (preferably using the <ref></ref> tags) and links to original data, as appropriate.
Causality
Model [1]
Cindoor sources = (NcigScig)/(a+k)Vt + (Scooktcook)/(a+k)Vt + (Swood stovetwood stove)/(a+k)Vt + (Scombustiontcombustion)/(a+k)Vt
- Ncig = number of cigarettes smoked in the time t
- Scig = a source strength for cigarettes (µg particles per cigarette)
- V = volume of the room (m3)
- a = aeration (h-1)
- t = time (h)
- K = average deposition (h-1)
- Scook = a source strength for cooking (µg/h)
- tcook = time of cooking activities (h)
- Swood stove = a source strength factor for wood stove (µg/h)
- twood stove = time of wood stove use (h)
- Scombustion = a source strength factor for other combustion sources (e.g. natural gas, fuel oil) (µg/h)
- tcombustion = Time of heating with other combustion sources (h)
Unit
Unit in which the result is expressed.
Formula
Algebra or other explicit methods if possible (e.g. Analytica code between the <anacode></anacode> delimiters).
Result
If possible, a numerical expression or distribution.
