Abstract Simultaneous measurements of volatile organic compounds (VOCs) using two PTR‐TOF‐MS instruments were conducted at urban and suburban sites New Delhi during the winter 2018. The time series VOC mixing ratios show substantial variations mainly influenced by local emissions meteorological conditions. Mixing methanol (∼28 ppbv), acetaldehyde (7.7 acetone (10.6 isoprene (2.8 ppbv) monoterpenes (0.84 site higher than those site, while levels aromatic VOCs almost similar. strong nighttime...
Abstract. Air quality networks in cities can be costly and inconsistent typically monitor a few pollutants. Space-based instruments provide global coverage spanning more than decade to determine trends air quality, augmenting surface networks. Here we target the UK (London Birmingham) India (Delhi Kanpur) use observations of nitrogen dioxide (NO2) from Ozone Monitoring Instrument (OMI), ammonia (NH3) Infrared Atmospheric Sounding Interferometer (IASI), formaldehyde (HCHO) OMI as proxy for...
Abstract. Low-cost sensors offer an attractive solution to the challenge of establishing affordable and dense spatio-temporal air quality monitoring networks with greater mobility lower maintenance costs. These low-cost reasonably consistent measurements but require in-field calibration improve agreement regulatory instruments. In this paper, we report results a deployment study on network six devices built using Alphasense O3 (OX-B431) NO2 (NO2-B43F) electrochemical gas sensors. The were...
In the present study, we assessed for first time performance of our custom-designed low-cost Particulate Matter (PM) monitoring devices (Atmos) in measuring PM10 concentrations. We examined ambient levels during an intense measurement campaign at two sites Delhi National Capital Region (NCR), India. this validated un-calibrated Atmos concentrations highly polluted sites. concentration from Atmos, containing laser scattering-based Plantower PM sensor, was comparable with that measured...
Abstract Delhi metropolitan area suffers from extreme haze during the post‐monsoon and winter season, impacting climate, public health, economy. We used a high‐resolution time‐of‐flight aerosol mass spectrometer (HR‐ToF‐AMS) aethalometer at two urban locations in to capture non‐refractory PM 2.5 (NR‐PM ) black carbon (BC) season of 2019–2020. Four periods with high composition based‐PM (C‐PM = NR‐PM + BC) concentration distinct chemical were identified, all which organics dominated but...
In recent times, a significant number of studies on the composition and sources fine particulate matters volatile organic compounds have been carried out over Delhi, either initiated by or in association with researchers from Indian Institute Technology Kanpur (IIT Kanpur), collaboration within outside India. All these utilized highly time-resolved, campaign-mode observations made state-of-the-art instrumentation during late winter months (mid-January to March) 2018. Individually, each were...
YABBY is among the specific transcription factor (TF) gene family in plants and plays an important role development of leaves floral organs. Its roles include lateral organ development, establishment dorsoventral polarity, response to abiotic stress. Potato crop worldwide genes are not still identified characterized potato. So, little has been known about potato until now. This study was carried out perform genome-wide analysis, which will provide in-depth analysis There have seven StYAB...

Cooking activities are responsible for substantial emissions of both particulate matter (PM) and volatile organic compounds (VOCs), two key indoor air pollutants, which can lead to numerous adverse health effects, including premature mortality. Chicken breast was prepared following tightly constrained cooking procedures with contrasting methods in a well‐controlled research kitchen investigate the PM VOC by simultaneous measurements reference instruments (an optical aerosol spectrometer...
In this communication, accumulated soot from typical Indian share autos and buses has been characterized using FE-SEM coupled with EDS FTIR spectroscopy for its toxicity level. Analysis reveals the size of spherical-shaped primary particles to be less than 40 nm, which agglomerate form fractal-like structures. autos, average weight percentage heavy metals such as Cr, Fe, Cu Pt (except Zn) is higher that in buses; trace elements include noncarbon elements. results suggest contaminate soil...
Despite several studies on traffic calming devices, information particulate matter contribution by vehicle abrasion and wear nearby vertical deflections of speed humps is scant. Many have been performed in the recent past heavy metal contamination at roads mainly intersections. On other hand, devices were studied for their effectiveness reducing thereby increasing road safety, but environmental effects are neglected. In present study, relation between concentrations Cu Zn (marker metals...
Air pollution is a public health emergency in large cities. The availability of commodity sensors and the advent Internet Things (IoT) enable deployment city-wide network 1000's low-cost real-time air quality monitors to help manage this challenge. This needs be supported by an IoT cyber-infrastructure for reliable scalable data acquisition from edge Cloud. low accuracy such also motivates need data-driven calibration models that can accurately predict science variables raw sensor signals....
In WSNs routing of data consumes a lot energy due to excessive flooding packets.In the proposed EERP scheme is done on basis intensity received signals.Unlike REEP, information packet forwarded by only one source sensor node.The packets are node which has maximum signal from object.Alternate paths also maintained through local flooding.Theoretical analysis and simulation results show that protocol more efficient as compared other existing protocols such Directed Diffusion REEP.
