Leaves (used for leaf area measurements), residual aboveground and root material of these individuals were separately chopped, finely ground with a ball mill and C and N concentrations were determined using an elemental analyser (Vario EL III Element Analyzer, Elementar, Hanau, Germany).
The elemental compositions (C, H, N) were analyzed using an organic element analyzer (Vario EL cube, Germany).
To understand the physiochemical properties of the tested dust samples, the element composition, particle size distribution, and heat release rate were obtained by utilizing an element analyzer, particle-size analyzer, and cone calorimeter, respectively.
Plant tissue %N was determined using a Eurovector Elemental Analyzer.
Carbon and nitrogen concentrations were determined using a CE Elantech NC 2500 Element Analyzer.
Increased CO2 concentration in the container was monitored using an infrared gas analyzer (Li-6262 CO2/H2O analyzer, LI-COR, Inc. USA).
Images were taken using an image analyzer (Typhoon, Amersham Biosciences).
The images were digitalized using an image analyzer (Chemimager, Biozym).
[ 17, 18] using an automatic analyzer.
Serum insulin was measured using an Immulite analyzer (Diagnostic Products).
