Polycyclic aromatic hydrocarbons (PAHs) in urban soils of the megacity Shanghai: occurrence, source apportionment and potential human health risk.
TLDR
The index of additive cancer risk (IACR) values in almost one third of urban soil samples were more than the safe value of 1.0, indicating these urban soil PAHs in the study area may pose a potential threat to potable groundwater water quality from leaching of carcinogenic PAH mixtures from soil.About:

Time to Say Goodbye to the 16 EPA PAHs? Toward an Up-to-Date Use of PACs for Environmental Purposes.
TL;DR: Although the state of knowledge has improved dramatically since the introduction of the 16 EPA PAHs in the 1970s, this summary shows that more research is needed about the toxicity, occurrence in the environment and chemical analysis, particularly of alkylatedPAHs, higher molecular weight PAHS and substituted PACs.

Polycyclic aromatic hydrocarbons in soils from urban to rural areas in Nanjing: Concentration, source, spatial distribution, and potential human health risk
TL;DR: It is concluded that urbanization has accelerated the accumulation of soil PAHs and increased the environmental risk for urban residents.

IARC Monographs on the Evaluation of Carcinogenic Risks to Humans
TL;DR: This timely monograph is a distillation of knowledge of hepatitis B, C and D, based on a review of 1000 studies by a small group of scientists, and it is concluded that hepatitis D virus cannot be classified as a human carcinogen.

Positive matrix factorization: A non-negative factor model with optimal utilization of error estimates of data values†
Pentti Paatero,Unto Tapper +1 more
TL;DR: In this paper, a new variant of Factor Analysis (PMF) is described, where the problem is solved in the weighted least squares sense: G and F are determined so that the Frobenius norm of E divided (element-by-element) by σ is minimized.

PAHs in the Fraser River basin: a critical appraisal of PAH ratios as indicators of PAH source and composition
Mark B. Yunker,Robie W. Macdonald,Roxanne Vingarzan,Reginald H. Mitchell,Darcy Goyette,Stephanie Sylvestre +5 more
TL;DR: In this paper, parent and alkyl PAHs were quantified in suspended particulates and sediments (345 samples) from the Fraser River system, British Columbia, Canada, and the best potential to distinguish natural and anthropogenic sources is exhibited by ratios of the principal mass 178, 202, 228 and 276 parent PAH, 1,7/2,6+1,7-DMP (dimethylphenanthrene), the phenanthrene/anthracene and fluoranthene/pyrene alkyal PAH series and several less commonly applied PA

Least squares formulation of robust non-negative factor analysis
TL;DR: Positive matrix factorization (PMF) is a recently published factor analytic technique where the left and right factor matrices (corresponding to scores and loadings) are constrained to non-negative values as mentioned in this paper.

Polycyclic Aromatic Hydrocarbons
TL;DR: In this article, the authors presented a classification of PAHs with two-three rings, four rings, five rings, six rings, and seven rings, as well as non-alternant PAH with three, four, and five rings.
