“…The concentration increased linearly with sonication time in the silica particle suspensions similar to the particle-free scenario ( Fig. 2 a–c), which is consistent with previous reports [17] , [36] . When φ p was low (0.05 vol%), slightly more I 3 − was detected at every point of time compared with the particle-free scenario; smaller particle diameters ( d p ) led to higher concentrations of I 3 − ( Fig.…”

“…The pH value was initially adjusted to 8 ± 0.2 with KOH (0.1 M, purchased from Chengdu Jinshan Chemical Reagent Co., Ltd.). This is because I − in acidic solutions are susceptible to oxidation by oxygen gas, and I 3 − in strongly alkaline solutions is more likely to react with H 2 O 2 (formed by the recombination of ·OH) to form I − [36] , [37] . The silica particles were placed in the vessel, and KI solution was added to a height of 10.0 cm, prior to the sonochemical experiments.…”

“…Eriochrome Black T has been used for the determination of magnesium (4, 9, 22, 23, 32) and for the simultaneous determination of calcium and magnesium (32). A recently reported reagent for magnesium, Magon (1,16,17), is sensitive and forms a fairly stable complex with magnesium.…”

“…Systematic ground-level O 3 monitoring began in the Los Angeles area in the 1950s. From 1959 to 1975, the California Air Resources Board (CARB) adopted a nonbuffered potassium iodide wet chemical method (Altshuller et al, 1959), which was found to have interferences from NO 2 and other trace oxidants such as peroxide, and PAN. As a consequence, the method was identified operationally as a total oxidant measure.…”

It is axiomatic that good measurements are integral to good public policy for environmental protection. The generalized term for "measurements" includes sampling and quantitation, data integrity, documentation, network design, sponsorship, operations, archiving, and accessing for applications. Each of these components has evolved and advanced over the last 200 years as knowledge of atmospheric chemistry and physics has matured. Air quality was first detected by what people could see and smell in contaminated air. Gaseous pollutants were found to react with certain materials or chemicals, changing the color of dissolved reagents such that their light absorption at selected wavelengths could be related to both the pollutant chemistry and its concentration. Airborne particles have challenged the development of a variety of sensory devices and laboratory assays for characterization of their enormous range of physical and chemical properties. Advanced electronics made possible the sampling, concentration, and detection of gases and particles, both in situ and in laboratory analysis of collected samples. Accurate and precise measurements by these methods have made possible advanced air quality management practices that led to decreasing concentrations over time. New technologies are leading to smaller and cheaper measurement systems that can further expand and enhance current air pollution monitoring networks. Implications: Ambient air quality measurement systems have a large influence on air quality management by determining compliance, tracking trends, elucidating pollutant transport and transformation, and relating concentrations to adverse effects. These systems consist of more than just instrumentation, and involve extensive support efforts for siting, maintenance, calibration, auditing, data validation, data management and access, and data interpretation. These requirements have largely been attained for criteria pollutants regulated by National Ambient Air Quality Standards, but they are rarely attained for nonroutine measurements and research studies.
