This review focuses on the observed characteristics of atmospheric new particle formation
(NPF) in different environments of the global troposphere. After a short introduction, we will …

Urban aerosol measurements are necessary to establish associations between air pollution
and human health outcomes and to evaluate the efficacy of air quality legislation and …

Can mitigating only particle mass, as the existing air quality measures do, ultimately lead to
reduction in ultrafine particles (UFP)? The aim of this study was to provide a broader urban …

In this study, the positive matrix factorization (PMF) model was used for source
apportionment of ambient PM 2.5 in two locations in the central Tehran from May 2012 …

Ultrafine particles (UFP) are suspected of having significant impacts on health. However,
there have only been a limited number of studies on sources of UFP compared to larger …

Quantitative estimations of sources and spatial distribution of soil heavy metals (HMs) is
essential for strategizing policies for soil protection and remediation. As a special soil …

Groundwater contamination by heavy metals (HMs) released by weathering and mineral
dissolution of granite, gneisses, ultramafic, and basaltic rock composition causes human …

In this study, urban stream sediment samples were collected in the Suzhou Industrial Park
(SIP), one of the earliest national demonstration eco-industrial parks of China. PAHs were …

In this study, we investigated long-term trends in the ambient concentrations and sources of
redox-active metals and trace elements in central Los Angeles over the period of 2005 …

This study aims at testing the effectiveness of Positive Matrix Factorization in characterizing
groundwater and surface water quality, in terms of identifying main hydrochemical features …
