“…A study in Bhubaneswar by Nayak et al, 2023 found out the acidic pH of the groundwater creates serious health risks in children and adults. Severe fluoride and nitrate contamination were found in the groundwater of North-West Delhi creating high public health risk with high hazard risk for children (Sarma & Singh, 2023). Similar research was done in smart cities of Telangana and in the Sonipat district of Haryana to check the toxicity of groundwater and observed cumulative hazard quotient to be more than one for both children and infants (Guddeti & Kurakalva, 2023;S.…”

Severe weather events, such as heat waves, floods, pollution, and health threats, are becoming more common in metropolitan places across the world. Overcrowding, poor infrastructure, and fast, unsustainable urbanization are some of the problems that India faces, and the country is also susceptible to natural disasters. This research analyzes climatic variables affecting urban hazards in Bangalore (also known as Bengaluru) via a thorough review. Heat waves, urban floods, heat islands, and drought were identified in 156 qualifying publications using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) method. Contributing variables were also considered. City development and urbanization were key to changing climate and increasing urban dangers. While long-term climatic variable distribution is uneven, warming is evident. The report promotes strong urban planning techniques, comprehensive policies, more green areas, and sustainable development beyond short-term heat response programs to boost urban climate resilience. This study shows how climate, land use, and urban dangers are interconnected. Future studies may benefit by categorizing urban risk studies and identifying climatic factors.

Taking Jiaozuo agglomeration area as the research area, the environmental quality evaluation was carried out. The monthly and annual variation characteristics of 6 basic pollutants and 3 supplementary monitoring pollutants were analyzed by single factor index and ambient air quality index ( AQI ). The results showed that the AQI value of the average concentration in 2019-2021 reached the secondary standard. Compared with the air quality in 2019 and 2020, the single factor pollution index decreased year by year in 2021. The annual air quality index of 2020 and 2021 shows that the average value of AQI increases from October to the highest value in January of the second year, decreases from January to the lowest value in July and August, and the three supplementary monitoring pollutants all meet the evaluation criteria. The ambient air quality pollutants in the study area are mainly PM10 and PM2.5. It is necessary to take corresponding measures to prevent air pollution and provide scientific basis for atmospheric environmental governance.

“…[9] India, a South Asian country identified as one of the top five most polluted countries, particularly highlights the severity of this issue, with its megacity Delhi consistently ranking among the world's most polluted regions and recording high concentrations of PM 2.5 throughout the year. [4,10,11] Many studies have attributed these high concentrations of PM 2.5 in Delhi to vehicular emissions. [4,12] Winter conditions, including cool temperatures, shallow boundary layer heights, and frequent temperature inversions, contribute to a further escalation of already increased PM 2.5 levels by trapping pollutants within the boundary layer.…”

In the last few years, urban trees have emerged as an effective nature‐based solution to mitigate increasing air pollutant levels due to urbanization and industrialization. This study aims to assess the synergistic effect of urban trees on improving air quality by combining real‐time PM2.5 monitoring with the i‐Tree Eco model. The monitoring was conducted during rush hours with high traffic volume and during non‐rush hours, in both the tree alley and a non‐tree road section within the industrial areas of the north‐west region of the National Capital Territory of Delhi, India. The i‐Tree Eco model was run using the diameter at breast height values of tree species present in the study area, and the PM2.5 reduction ability of the trees was quantified. The results from both approaches indicated that urban trees can significantly reduce the traffic‐fed PM2.5 concentrations. Therefore, it is suggested that tree plantations be integrated into air pollution management strategies in urbanized regions with high traffic volumes. Although this study explores the initial link between trees and air quality in Delhi, further research incorporating local wind speed and direction measurements would provide a more comprehensive understanding of how trees influence air quality in any highly polluted urban setting.
