A comprehensive analysis of heavy metals in urban road dust of Xi'an, China: Contamination, source apportionment and spatial distribution.

TLDR
The location of point pollution sources and prevailing wind direction were found to be important factors in the spatial distribution of heavy metals and there was significant enrichment of Pb, Zn, Co, Cu and Cr based on geo-accumulation index value.

Pollution characteristics, sources, and health risk assessment of human exposure to Cu, Zn, Cd and Pb pollution in urban street dust across China between 2009 and 2018.

TL;DR: The health risk assessment indicated that ingestion is the most important pathway of exposure to metal pollution in street dust for both children and adults, followed by dermal contact and inhalation, and the health risks for children were higher than those for adults.
Journal ArticleDOI

A new exploration of health risk assessment quantification from sources of soil heavy metals under different land use.

TL;DR: A health risk assessment (HRA) model combined with PMF was proposed to assess quantificationally the human health risk (including non-cancer risk and cancer risk) from sources under residential-land, forest-land and farm land, thus providing certain reference in preventing and controlling the pollution from the source for local authorities effectively.

Source identification and spatial distribution of arsenic and heavy metals in agricultural soil around Hunan industrial estate by positive matrix factorization model, principle components analysis and geo statistical analysis.

TL;DR: The soil was polluted by As and heavy metals in different degree, which had harmful impact on human health and the PMF was applied to better identify pollution sources of As andheavy metals in soil.

Soil and Human Health: Current Status and Future Needs:

TL;DR: Soil is an ecosystem with a myriad of interconnected parts, each influencing the other, and when all necessary parts are present and functioning (i.e., the soil is healthy), human health also benefits.

A review of heavy metal contaminations in urban soils, urban road dusts and agricultural soils from China.

TL;DR: In this paper, the authors reviewed quite a few heavy metal contamination related studies in several cities from China over the past 10 years and discussed the concentrations, sources, contamination levels, sample collection and analytical tools of heavy metals in urban soils, urban road dusts and agricultural soils.

Multivariate statistical and GIS-based approach to identify heavy metal sources in soils

TL;DR: The study indicates that background values and realistic mandatory guidelines are impossible to fix without an extensive data collection and without a correct geochemical interpretation of the data.
Journal ArticleDOI

Multivariate analysis of heavy metal contamination in urban dusts of Xi’an, Central China

TL;DR: The results indicate that, in comparison with Chinese soil, urban dusts in Xi'an have elevated metal concentrations as a whole, except those of arsenic and manganese, which are comparable to those in other studies.

Source Apportionment of Polycyclic Aromatic Hydrocarbons in the Urban Atmosphere: A Comparison of Three Methods

TL;DR: The sources of PAHs to ambient air in Baltimore, MD, were determined by using three source apportionment methods, principal component analysis with multiple linear regression, UNMIX, and positive matrix factorization.
