“…Water, two surfactants (cationic CTAB and anionic SDS) as well as a buffer solution (NaHCO 3 /Na 2 CO 3 ) applied for fluoride IC determination were examined. According to Talebi and Abedi (2005), the use of a surfactant in extraction of anions from airborne particulate matter could increase the extraction yield. The results from these experiments based on at least three replicates are presented in Fig.…”

“…Certified values are restricted to constituent and trace elements and the material certificate also lists complementary concentration values of some inorganic anions including chlorine, nitrate and sulfate. It can be utilized in the evaluation of methods used in inorganic analysis of atmospheric particulate matter and samples with similar matrices (Talebi and Abedi, 2005;Karthikeyan and Balasubramanian, 2006;Karthikeyan et al, 2007;García et al, 2008;Salcedo et al, 2014). Water, two surfactants (cationic CTAB and anionic SDS) as well as a buffer solution (NaHCO 3 /Na 2 CO 3 ) applied for fluoride IC determination were examined.…”

“…The masses of quartz filters were determined by gravimetry, and the watersoluble ions and carbonaceous species were determined. The amounts of water-soluble ions (SO 2 -4 , NO -3 and Cl -) were determined by ion chromatography (DX-100, Dionex Ltd., USA) [11][12][13]. The total carbon (sum of organic carbon and elemental carbon, TC) and organic carbon (OC) in quartz filters were determined using an element analyzer (VarioE1, Elementar Analysensysteme Gmbh, Hanau, Germany) [14][15][16].…”

A total of 168 PM 10 samples were collected during the year of 2005 at eight sites in the city of Wuxi in China. Fifteen chemical elements, three water-soluble ions, total carbon and organic carbon were analyzed. Six source categories were identified and their contributions to ambient PM 10 in Wuxi were estimated using a nested chemical mass balance method that reduces the effects of colinearity on the chemical mass balance model. In addition, the concentrations of secondary aerosols, such as secondary organic carbon, sulfate and nitrate, were quantified. The spatially averaged PM 10 was high in the spring and winter (123 μg$m -3 and low in the summer-fall (90 μg$m -3 ). According to the result of source apportionment, resuspended dust was the largest contributor to ambient PM 10 , accounting for more than 50% of the PM 10 mass. Coal combustion (14.6%) and vehicle exhaust (9.4%) were also significant source categories of ambient PM 10 . Construction and cement dust, sulfates, secondary organic carbon, and nitrates made contributions ranging between 4.1% and 4.9%. Other source categories such as steel manufacturing dust and soil dust made low contributions to ambient PM 10 .

“…Although many tests of water extraction efficiency from filters have been conducted over the decades, few results from these tests have been published (Fosco and Schmeling 2007;Hoffer et al 1979;Talebi and Abedi 2005). These tests involve either spiking the filter with known amounts of the ions using a microsyringe, comparing a less aggressive extraction with a more proven aggressive method, or by submitting an extracted filter to a second Miyazaki et al (2014) f Methanesulfonic acid is produced by hydrolysis of dimethyl sulfoxide (Davison 1996), which is produced from the photochemical oxidation of dimethyl sulfide by marine algae and salt marsh plants (Baker et al 1991) Fig.…”

Ion chromatography (IC) is widely used to quantify sulfate, nitrate, ammonium, sodium, chloride, and potassium from PM 2:5 water extracts. IC hardware and software have progressed to allow a broader range of water-soluble compounds to be determined for the existing anion and cation programs and on the same solutions using analytical column, eluent, and detector modifications. Alkylamine, organic acid, and carbohydrate quantification by IC expands the number of source markers, especially for different types of biomass burning and secondary organic aerosols. Although modern systems are highly automated, internal quality control (QC) and external quality assurance (QA) programs are essential. QC includes detailed standard operating procedures, calibration over the range of expected concentrations, performance tests with independent standards, inspection of filters and chromatograms, and anion/cation balances. QA consists of independent system and performance audits, analysis of externally prepared performance samples, and interlaboratory comparisons. The additional water-soluble species provide compounds for speciated emission inventories, source markers to refine aerosol source apportionment, and increased understanding of global carbon, sulfur, and nitrogen cycles.
