AB  - Polycyclic aromatic hydrocarbon (PAHs) were measured in sediments from 29 sites 
      throughout Taihu Lake in China during 2 seasons to investigate spatiotemporal 
      characteristics and source contributions using a 3-way source apportionment 
      approach to positive matrix factorization (PMF3). Seasonal and spatial variations 
      of levels and toxicity suggested higher individual carcinogenic PAH 
      concentrations and toxic equivalent quantity (TEQ) in the flooding season. 
      Three-way PAHs dataset (PAH species, spatial variability, and seasonal 
      variability) was analyzed by PMF3, and its results were compared with a widely 
      used 2-way model (PMF2). Consistent results were observed: vehicular emission was 
      the most important contributor (67.08% by PMF2 and 61.83% by PMF3 for the 
      flooding season; 54.21% by PMF2 and 52.94% by PMF3 for dry season), followed by 
      coal combustion and wood combustion in both seasons. The PMF-cluster analysis was 
      employed to investigate spatial variability of source contributions. Findings can 
      introduce the 3-way approach to apportion sources of PAHs and other persistent 
      organic pollutants (POPs) in sediments, offering the advantage of accounting for 
      information on 3-way datasets.
