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

C_{indoor sources} = (N_cigS_cig)/(a+k)Vt + (S_cookt_cook)/(a+k)Vt + (S_{wood stove}t_{wood stove})/(a+k)Vt + (S_combustiont_combustion)/(a+k)Vt

• N_cig = number of cigarettes smoked in the time t
• S_cig = 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)
• S_cook = a source strength for cooking (µg/h)
• t_cook = time of cooking activities (h)
• S_{wood stove} = a source strength factor for wood stove (µg/h)
• t_{wood stove} = time of wood stove use (h)
• S_combustion = a source strength factor for other combustion sources (e.g. natural gas, fuel oil) (µg/h)
• t_combustion = 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.
