Gaseous air pollutants are frequently present together in the environment downwind from industrial developments and thus have the potential to cause interactive effects on biological receptors. Accordingly, an investigation was conducted to determine how combinations of the gaseous pollutants, sulfur dioxide (SO2) and nitrogen dioxide (NO2) affect a major crop. Open-air field plots of soybeans (Glycine max L.) were exposed to eight different dose levels of SO2 and NO2, alone and in combination, in the presence of ambient ozone (O3) during 1980 and 1981. The soybean plots were fumigated on 10 occasions in both years of the study during the pod-filling period for an average exposure time during fumigation of approximately 3 h. Mean concentrations during fumigation periods ranged from 0.13 to 0.42 ppm SO2 and 0.06 to 0.40 ppm NO2. Premature senescence, as measured by chlorophyll degradation, was observed in the combined pollutant plots in both years of the experiment. Fumigations with NO2 alone had no effect on seed yields in either year. Exposures with SO2 alone had no effect on yields in 1980 and decreased yields by up to 6% in 1981, possibly as a result of greater concentration peaks. Combinations of SO2 and NO2 had a synergistic effect in both years of the study and resulted in yield decreases ranging from 9 to 25%, depending on pollutant dose.

The measurement of air pollutants emitted to the atmosphere in exhaust gases from stationary gas turbines must be made in accordance with applicable government specifications in those cases where the measurements are being made to determine compliance with regulations. This paper reviews the methods for measuring opacity, sulfur dioxide, oxides of nitrogen, carbon monoxide, carbon dioxide, oxygen, hydrocarbons, and particulates. In addition, the paper references the Federal Register (volume, number, and page) in which the official specification appears. Other methods, including ASME, SAE, and ASTM, are listed where applicable.

Particulate matter studies have been conducted regularly in the capital city of Mongolia. In contrast, studies related to the source and general estimation of levels of sulfur dioxide (SO2) over whole years are lacking. To explore the yearly trend in SO2, whole-year data of air pollutants were obtained from the Air Pollution Reducing Department. The results showed that the annual average concentration of SO2 was 32.43 µg/m3 at the Amgalan official monitoring station in 2017, which changed from 53 µg/m3 in 2016, representing a reduction of around 40%. The back-trajectory model and the National Oceanic and Atmospheric Administration (NOAA)’s hybrid single particle Lagrangian integrated trajectory model (HYPSLIT) were used to determine the source of SO2. A total of 8760 backward trajectories were divided into eight groups. The results showed that 78.8% of the total trajectories in Ulaanbaatar came from an area inside Mongolia. The results showed that pollutants enter Ulaanbaatar mainly from the northwest and north during the winter season. There are industrial cities, such as Darkhan and Sukhbaatar, in North Mongolia. Air pollutants created in the industrial area traveled into Ulaanbaatar during the winter season.

Although studies have suggested environmental factors to be triggers of headache, the contribution of long-term air pollution exposure to recurrent headaches is poorly understood. Hence, we executed this nationwide cohort study to investigate associations between levels of ambient air pollutants and risks of recurrent headaches in children in Taiwan from 2000 to 2012. We used data from the Taiwan National Health Insurance Research Database and linked them to the Taiwan Air Quality Monitoring Database. Overall, 218,008 children aged < 18 were identified from 1 January 2000, and then followed until they were diagnosed by a physician for ≥3 times with recurrent headaches or until 31 December 2012. We categorized the annual average concentration of each air pollutant (fine particulate matter, total hydrocarbon, methane, sulfur dioxide, and nitrogen dioxide) into quartiles (Q1–Q4). We measured the incidence rate, hazard ratios (HRs), and the corresponding 95% confidence intervals for recurrent headaches. stratified by the quartiles. A total of 28,037 children (12.9%) were identified with recurrent headaches. The incidence rate and adjusted HR for recurrent headaches increased with higher-level exposure of air pollutants, except sulfur dioxide. We herein demonstrate that long-term ambient air pollutant exposure might be a risk factor for childhood recurrent headaches.
