Atmospheric-particulates-bound mercury Hg(p) study at five characteristic sampling sites in Taiwan

Environmental Monitoring and Assessment, 2010
The main purpose for this study is to observe the seasonal and month variations for particulates-bound mercury Hg(p) in total suspended particulates (TSP) concentration, dry deposition at five characteristic sampling sites during years of 2009-2010 in central Taiwan.

Measurements of size-fractionated concentration and bulk dry deposition of atmospheric particulate bound mercury

Atmospheric Environment, 2012
Abstract Daily samples of size-fractionated (18, 10, 2.5 and 1.0 μm) particulate-bound mercury Hg(p) were collected using Micro-Orifice Uniform Deposition Impactors (MOUDI), on randomly selected days each month between November 2010 and July 2011, at a traffic site (Hungkuang), a wetland site (Gaomei), and an industrial site (Quanxing) in central ...

Particulate bound mercury Hg(p) concentrations, compositions and dry depositions study around mixed and agricultural (MA) sites

Environmental Forensics, 2020
TSP concentrations in ambient air and dry deposition were measured at an (agricultural) sampling site in Taiping. The TSP concentrations are compared with those in the other counties in Asia.

Uncertainty estimation in analysis of particulate-bound mercury in different size fractions of PM10 in ambient air

Accreditation and Quality Assurance, 2011
Different size fractions with aerodynamic diameters of (9.0–10.0) μm, (5.8–9.0) μm, (4.7–5.8) μm, (3.3–4.7) μm, (2.1–3.3) μm, (1.1–2.1) μm, (0.7–1.1) μm, and (0.4–0.7) μm of PM10 were collected on glass fiber filter using 8-stage Andersen cascade impactor.

Particulate and particulate-bound mercury concentrations and size distributions as related to seasonal variations during peak demand/non-peak demand periods

Journal of Environmental Science and Health, Part A, 2020
The particulate size distributions of aerosol pollutants (particulates and Hg(p)) at a mixed site were measured and their seasonal variations identified. Atmospheric particulates and the Hg(p) mass median diameter (m.m.d.) were obtained. Hg(p) concentrations increased by approximately 20% during the peak demand period for all particle sizes (18, 10, 2 ...

Concentrations of particulates in ambient air, gaseous elementary mercury (GEM), and particulate-bound mercury (Hg(p)) at a traffic sampling site: a study of dry deposition in daytime and nighttime

Environmental Geochemistry and Health, 2013
In this investigation, the concentrations of particles in ambient air, gaseous elemental mercury (GEM), and particulate-bound mercury (Hg(p)) in total suspended particulates (TSP) as well as dry deposition at a (Traffic) sampling site at Hung-kuang were studied during the day and night in 2012.

Application of Dry Deposition Models to Estimate Ambient Air Particulate and Particulate-Bound Mercury Hg(p) Dry Deposition

Environmental Engineering Science, 2011
Abstract Ambient air samples were collected between September 3, 2009 and March 5, 2010 to determine total suspended particulate matter (TSP) and coarse and fine particulate and particle-bound mercury Hg(p) at the suburban/coastal sampling station of Sha-Lu at Taiwan.

Seasonal Variations (Autumn, Winter, and Spring) of Atmospheric Particulate and Particulate-Bound Mercury Hg(p) at a Suburban/Coastal Area

Environmental Forensics, 2010
From September 3, 2009, to March 5, 2010, the dry deposition, total suspended particulate (TSP) matter, coarse and fine particulates, and bound mercury (Hg[p]) in the atmosphere were investigated at Bei-Shi sampling site in central Taiwan. When using projection film as collection medium, the average ambient air particulates for day dry deposition ...
