Correction to :Size-resolved identification, characterization and quantification of primary biological organic aerosol at a european rural site(Environ. Sci. Technol. (2016) 50 (3425−3434) DOI : 10.1021/acs.est.5b05960).

Thedeterminationauthors regretofthatambienta calculationcelluloseerrorconcentrationsoccurred infromthe filter loadings in our article “Size-resolved Identification, Characterization and Quantification of Primary Biological Organic Aerosol at a European Rural Site”. This resulted in cellulose concentrations that were biased high by a factor 2. The correct summer average cellulose contribution to the coarse organic matter (OMCOARSE) fraction was 24 ± 12%. The summer cellulose contribution to the water insoluble OMCOARSEwas 43%avg(pg. 3430). Cellulose together with WSOM represented 62% of OMCOARSE(pg. 3430). The median WSPBOA:Cellulose ratio was 0.61, first quartile 0.51, third quartile 0.81 (SI, pg. S20, line 297). This error decreases the initial contribution of cellulose, but does not alter the conclusions of the original article. The Graphical TOC entry and Figure 1 were corrected as follows
