Since our biomass estimates did not include reproductive parts (Supporting Information S1, Fig. S1), flower buds were cut off regularly to ensure maximal allocation to vegetative growth [68], [69], [70].
Some studies used to calculate strength of association (OR) between chronic bronchitis and biomass cooking fuel exposure did not include chronic bronchitis as the outcome per se, therefore chronic obstructive pulmonary disease (COPD) or abnormal peak expiratory flow rate (PEFR) are taken to serve as proxy.
We did not include biomass fuel used for heating or lighting purposes in this study because their emission levels, exposure, and health risks are likely to be different from cooking fuel.
It did not include bacterial biomass formation in PIII and therefore bacterial consumption could be much higher.
For example, Williams et al. [12] estimated this component to be the largest reservoir of C in the vineyard landscape they examined, but they did not include root biomass in their calculations.
Because carbon in biofuels is stored for a negligible amount of time, we did not include a product storage term for biomass used to produce ethanol.
(2005) did not find any reliable QSAR to estimate the first-order biomass-normalized rate coefficients of 22 PAH, however their study did not include a comprehensive analysis of all possible molecular descriptors.
We rarely found evidence of wolves feeding on carcasses at single locations and did not include these carcasses because wolves did not obtain significant biomass (see Text S2).
Where estimates did not include transport (and/or size-reduction), a uniform cost was assumed, determined by the biomass form and country of origin as outlined in Table 2[ 13, 13].
Where estimates did not include transport (and/or size reduction), a constant carbon intensity was assumed for each operation, its value determined by the biomass form (see Table 1, [ 24- 27]).
