“…Moreover, only during seven percentage of the sampling days in the entire campaign, the 24-h mean PM 10 mass concentration was less than the permissible limit of national ambient air quality standard (100 µg/m 3 ) framed by Central Pollution Control Board (CPCB), whereas none of the sampling day showed concentration less than World Health Organization's standard (50 µg/m 3 ). On comparing the results obtained in this study with other studies around the world on cities situated in a valley-based topography, it was observed that the 24-h average mass concentration of PM 10 observed at Doon valley was higher than that reported in Kathmandu valley, Nepal (127.70 µg/ m 3 In the present study, approximately 28% of the sampling days were weekends (Saturday and Sunday) and 72% were weekdays (remaining days of the week). The 24-h mean PM 10 observed during weekends was 148.39 ± 35.5 µg/ m 3 and during weekdays was 162.58 ± 31.9 µg/m 3 .…”

“…Atmospheric particulate matter (PM) considered as one of the criteria air pollutants [1] is diverse and complex to understand in terms of source, morphology, composition, size distribution, and mixing state [2]. In India, most of the research studies on atmospheric PM have focused on the elemental composition of particles [3][4][5]. However, several researchers have investigated both the physical (shape and size) and elemental characteristics of atmospheric PM through scanning electron microscope (SEM) and SEM-energy-dispersive X-ray spectroscopy (SEM-EDX), respectively [6][7][8].…”

Investigation of the source, morphology, and trace elements associated with atmospheric PM10 and human health risks due to inhalation of carcinogenic elements at Dehradun, an Indo-Himalayan city

To study the physical and chemical properties of atmospheric particulate matter over Dehradun city located along the foothills of the Himalayas, both in situ and satellite-based observations were utilized in the present research. Ambient respirable suspended particles denoted by PM 10 (atmospheric particulate matter having an aerodynamic diameter of ≤ 10 µm) was measured during 2016-2017. The morphology and elemental characteristics of PM 10 was studied through scanning electron microscopy (SEM) and SEM-energy-dispersive X-ray spectroscopy, respectively. The 24-h mean ± standard deviation of PM 10 was observed to be 158.6 ± 33.4 µg/m 3 , which is more than 2 times the permissible limit of World Health Organization (50 µg/m 3). Microscopic analysis revealed particles with irregular, porous, rounded, flaky, chain and branched structures indicating various types such as tar balls, soot, crystalline and biogenic particles. The frequently found particle types were investigated for the atomic percentage contribution, which revealed vehicular exhaust, industrial emission, biomass burning, and crustal/dust re-suspension as the chief source of PM 10. To delineate the source and transport pathway of air masses converging over the city, 24-h air mass back trajectories were associated with MODerate resolution Imaging Spectroradiometer derived fire spots, geographical location of cement manufacturing and thermal power plants in the vicinity of monitoring site. Excess cancer risk due to inhalation of Lead particles (mean = 0.159 µg/m 3) associated with PM 10 was 0.16 × 10 −6 , which is well below the safe limit (1 × 10 −6) framed by the United States Environment Protection Agency.

“…To address India’s air pollution crisis, refinement of local epidemiologic evidence is needed. The research base in this area is steadily expanding [ 7 , 10 , 25 , 70 , 88 , 98 , 111 , 126 , 127 , 128 , 129 , 130 , 131 , 132 , 133 , 134 ] and future investigations would benefit from robust and transparent systems for pollution data reporting, archival, and access.…”

Indian cities struggle with some of the highest ambient air pollution levels in the world. While national efforts are building momentum towards concerted action to reduce air pollution, individual cities are taking action on this challenge to protect communities from the many health problems caused by this harmful environmental exposure. In 2017, the city of Ahmedabad launched a regional air pollution monitoring and risk communication project, the Air Information and Response (AIR) Plan. The centerpiece of the plan is an air quality index developed by the Indian Institute of Tropical Meteorology’s System for Air Quality and Weather Forecasting and Research program that summarizes information from 10 new continuous air pollution monitoring stations in the region, each reporting data that can help people avoid harmful exposures and inform policy strategies to achieve cleaner air. This paper focuses on the motivation, development, and implementation of Ahmedabad’s AIR Plan. The project is discussed in terms of its collaborative roots, public health purpose in addressing the grave threat of air pollution (particularly to vulnerable groups), technical aspects in deploying air monitoring technology, and broader goals for the dissemination of an air quality index linked to specific health messages and suggested actions to reduce harmful exposures. The city of Ahmedabad is among the first cities in India where city leaders, state government, and civil society are proactively working together to address the country’s air pollution challenge with a focus on public health. The lessons learned from the development of the AIR Plan serve as a template for other cities aiming to address the heavy burden of air pollution on public health. Effective working relationships are vital since they form the foundation for long-term success and useful knowledge sharing beyond a single city.

“…The DS1820 temperature sensor collects the temperature and returns the digital information [9].As shown in Figure 6, After initialization, the sensor reads the data in ROM: the serial number and the temperature information of DS1820 [10]. The general delay 1s can read the temperature information, and then the pointer in the buffer is added to the next data reading [11].…”

This Scenic area has large traffic volume and complex environment and some scenic areas need to be protected. So developing an air quality monitoring system is very important. In this paper, the temperature sensor, the PM2.5 sensor and the wireless transmission module were combined by the MCU. It monitors the spot in PM2.5 concentration and the temperature information. When the PM2.5 concentration is higher than the threshold, the wireless transmission module sends the warning signal. So the system could measure and improve the environment of scenic spot.
