Question

What is the exposure to fine particles (PM2.5) in the Finnish population? Only outdoor sources are considered here. Exposures are calculated for defined locations (listed in a table in Rationale).

----#: . This could be implemented (as a method) for any locations in Finland, but the calculations are so slow that it is better to calculate actual answers for specified locations (as a variable) before applying it in a model. --Jouni (talk) 16:58, 5 March 2014 (EET) (type: truth; paradigms: science: comment)
