During the COVID-19 pandemic, governments in many countries worldwide, including India, imposed several restriction measures, lockdowns, to prevent spread of infection. lockdowns led a reduction gaseous and particulate pollutants ambient air. In present study, we investigated substantial changes selected volatile organic compounds (VOCs) after outbreak coronavirus pandemic associations with health risk assessments industrial areas. VOC data from 1 January 2019 31 December 2021 were collected...
The purpose of this study was to investigate the concentrations volatile organic compounds (VOCs) in different indoor microenvironments residential homes and hostels an academic institute, New Delhi, during March-May 2011. Eleven VOCs (aromatic halogenated) were assessed. Sampling analytical procedure based on National Institute for Occupational Safety Health (NIOSH) standard method. lifetime cancer non-cancer risk calculated targeted using US Environmental Protection Agency guidelines. mean...
Novel Coronavirus disease (COVID-19), after being identified in late December 2019 Wuhan city of China, spread very fast and has affected all the countries world. The impact lockdowns on particulate matter during lockdown period needs attention to explore correlation between anthropogenic natural emissions. current study demonstrated changes fine PM 2.5 , 10 their effect air quality lockdown. before was low New Delhi (India) Riyadh (Saudi Arabia), among major cities worldwide. India is...
The COVID-19 pandemic that emerged in Wuhan city of China December 2019 has adversely impacted the health and economy, society, other significant spheres human environment. severely economic activities, especially industrial production, transportation, tourism, hoteling industries. present study analyses impact varying severity lockdowns activities during various phases on water quality Yamuna river parameters like pH values, biological oxygen demand, chemical dissolved oxygen, total...
The concentrations of particulate and gaseous Polycyclic Hydrocarbons Carbon (PAHs) were determined in the urban atmosphere Delhi different seasons (winter, summer, monsoon).The samples collected using instrument air metric (particulate phase) charcoal tube (gaseous analyzed through Gas chromatography. principal component correlation used to identify sources PAHs during seasons.The mean concentration sum total (TPAHs) for phases at all sites found be higher winter season (165.14 ± 50.44...
In late December 2019, a novel coronavirus, COVID −19 originated in Wuhan city of China, and significant improvement not only the air quality but also water quality. Therefore, current study demonstrates changes parameters Ghaggar river, Punjab, India. The variations river have been examined during pre-, during, post-pandemic periods. maximum temperature for all monitoring stations was between 28 to 37°C pandemic period, whereas dissolved oxygen value varied from 3 7 mg/L. pH obtained...
Coronavirus disease has affected the entire population worldwide in terms of physical and environmental consequences. Therefore, current study demonstrates changes concentration gaseous pollutants their health effects during COVID-19 pandemic Delhi, national capital city India.
The problem of water scarcity and clean in sub-Saharan Africa is a growing concern. This study aims to quantify the quality on temporal scale Doorndraai dam site design possible management options. Here, an integrated approach using both in-situ measurements parameters remote sensing data was used derive index (WQI) inherent optical properties deduce factors governing seasonal annual variability. results show that all analyzed fall under permissible limit World Health Organization (WHO) for...
In December 2019, a novel coronavirus disease (COVID-19) outbreak occurred due to human respiratory virus that originated in the city of Wuhan, China. During COVID-19 lockdown, there was significant improvement air quality across world. We analyzed data for BTEX over three years (January 2019 2021) with pairwise comparison and trend analysis pre-, during, post-pandemic periods. This study demonstrates substantial changes concentration VOCs urban area (Punjab) lockdown effects. The results...
This study examines land use changes and evaluates the past projected forest carbon sequestration its valuation in Viti Levu Island, Fiji, through a combination of remote sensing with geospatial-based modeling approach. Land classification was performed using Landsat 7 8 imageries years 2000 2020; then, cellular automata artificial neural network (CA-ANN) conducted to predict map 2040. Carbon economic were estimated maps past, present, future (2000, 2020, 2040) within Integrated Valuation...
