Reactive oxygen species activity and chemical speciation of size-fractionated atmospheric particulate matter from Lahore, Pakistan: an important role for transition metals.
In this study a sensitive macrophage-based in vitro reactive oxygen species (ROS) assay was coupled with chemical fractionation tools and a year-long sampling program to further our understanding of the role of water-soluble metals in aerosol toxicity. The location is the polluted urban environment of Lahore, Pakistan, where we collected 24 h PM10 and PM2.5 samples every 6(th) day from January ...
متن کاملChemical Mass Balance Source Apportionment of Size-Fractionated Particulate Matter in Nanjing, China
In recent years, atmospheric particulate matter has become the primary air pollutant in Nanjing, China. In order to support a scientific basis for particles reduction, it is of great importance to investigate the contribution of different sources to particulate matter. In this paper, the characteristics of chemical composition of observational data for size-fractionated particulate matter at Gu...
متن کاملMeasuring Submicron-size Fractionated Particulate Matter on Aluminum Impactor Disks
Submicron-sized airborne particulate matter (PM) is not collected well on regular quartz or glass fiber filter papers. We used a micro-orifice uniform deposit impactor (MOUDI) to fractionate PM into 6 size fractions and deposit it on specially designed high-purity thin aluminum disks. The MOUDI separated PM into fractions 56–100, 100–180, 180–320, 320–560, 560–1000, and 1000–1800 nm. Since the ...
متن کاملA study on the composition of size-fractionated suspended particulate matter in shallow coastal waters of Chabahar Bay
Abstract In the present study, sampling and analysis of size-fractionated suspended particulate matter (SPM) in coastal waters of Chabahar Bay have been done for the first time. Sampling has been conducted on December 25 of 2018 from 5 stations in different locations of the Bay in order to evaluate the effects of natural and human activities on SPM mass and composition. With an overall average...
متن کاملChemical Speciation of Particulate Matter Pollution in Urban Dhaka City
Dhaka, the capital and largest city of Bangladesh, lacks a regular air pollution monitoring network to measure and assess ambient air pollution level. Several academic and research projects attempted to measure a limited number of air pollutants near roadways in the central business district. These studies revealed that ambient concentrations of lead, benzene, particulate matter, carbon monoxid...
