A review of particulate pollution over Himalaya region: Characteristics and salient factors contributing ambient PM pollution
2023, Atmospheric EnvironmentCitation Excerpt :However, studies on the region's air quality are scarce. As a result of the IGP's proximity to the Himalayas, this formerly pristine environment has become contaminated and burdened by increased air pollution from IGP-influenced areas, so sustaining habitats are especially sensitive to severe risks of pollution (Lüthi et al., 2015; Marinoni et al., 2013). Air pollution is a severe health problem, particularly in mega-cities, i.e., New Delhi, with an excess of 3500 cardiovascular mortality annually (Gurjar et al., 2010).
Variability of ambient black carbon concentration in the Central Himalaya and its assessment over the Hindu Kush Himalayan region
2023, Science of the Total EnvironmentSources, characteristics and climate impact of light-absorbing aerosols over the Tibetan Plateau
2022, Earth-Science ReviewsCitation Excerpt :Fossil fuels contribute approximately 54% of BC LAI on the southern slopes of the Himalayas (Kang et al., 2020a). Moreover, BC from Central Asia and northwestern India can also be transported to the TP by westerly winds and local valley winds in the Himalayas (Kang et al., 2020b; Ming et al., 2008; Bonasoni et al., 2010; Marinoni et al., 2013). BC deposition in the inland TP is relatively small due to the high topography of the TP (Lu et al., 2012).
Black carbon concentration in the central Himalayas: Impact on glacier melt and potential source contribution
2021, Environmental PollutionSeasonal variability and source apportionment of black carbon over a rural high-altitude and an urban site in western India
2021, Atmospheric Pollution ResearchCitation Excerpt :Black carbon is the sooty black material emitted from diesel engines, coal-fired power plants, and other sources that burn fossil fuel such as cooking stoves and forest fires. Long-range transport from other regions also adds up to the ambient BC loading (Zhao et al., 2012; Marinoni et al., 2013). The carbonaceous aerosols over the south Asia region is majorly contributed by industrial emissions, vehicle exhausts, domestic biofuel burning, agricultural crop-residue burning and wildfires (Ramanathan and Carmichael, 2008; Kaskaoutis et al., 2014; Rajesh and Ramachandran, 2017; Mahata et al., 2017; Wan et al., 2017; Dumka et al., 2018; Buchunde et al., 2019).
