Possible Overestimation Of Nitrogen Dioxide Outgassing During The Beirut 2020 Explosion, Ashraf Farahat, Nayla El-Kork, Ramesh P. Singh, Feng Jing

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

On 4 August 2020, a strong explosion occurred near the Beirut seaport, Lebanon and killed more than 200 people and damaged numerous buildings in the vicinity. As Amonium Nitrate (AN) caused the explosion, many studies claimed the release of large amounts of NO₂ in the atmosphere may have resulted in a health hazard in Beirut and the vicinity. In order to reasonably evaluate the significance of NO₂ amounts released in the atmosphere, it is important to investigate the spatio-temporal distribution of NO₂ during and after the blast and compare it to the average day-to-day background emissions from …

The Particle Problem: Using Rcra Citizen Suits To Fill Gaps In The Clean Air Act, Kurt Wohlers

Michigan Law Review

While the Clean Air Act has done a substantial amount for the environment and the health of individuals in the United States, there is still much to be done. For all its complexity, the Act has perpetuated systemic inequities and allowed harms to fall more heavily on low-income communities and communities of color. This is no less true for particulate matter pollution, which is becoming worse by the year and is a significant cause of illness and premature death. This Note argues that particulate pollution, traditionally only regulated on the federal level within the ambit of the Clean Air Act, …

“Temporal Not Permanent:” The Impact Of Covid-19 Cities Lockdown On Improving Air Quality — A Critical Review Of Africa, Emmanuel Mensah Aboagye, Felix Mensah, Kwaku Obeng Effah, Sandylove Afrane, Jeffrey Dankwa Ampah, Selina Annah Brenyah

Journal of Environmental Sustainability

The WHO declared the novel Covid-19 virus a global pandemic shortly after it broke out. The deadly virus spread has affected human health and seriously halted many economic and industrial activities globally. However, there has been a blight as there has generally been an improvement in air quality since the deadly Covid-19 pandemic caused various governments to lockdown their cities to regulate the spread of the virus. Since the widespread of Covid-19, there have been several researches to measure the extent of impact Covid-19 city lockdown has had global air quality, but no critical review has been done in Africa …

Dampak Kebijakan Psbb Terhadap Konsentrasi Pm2.5 Di Indonesia, Erwin Dariyanto

Jurnal Kebijakan Ekonomi

The aims of this study was to examine the impact of implementation of the Large-Scale Social Restriction or PSBB policy on the concentration of particulate matter 2.5 (PM_2.5). The observation period lasted from September 1, 2019 to December 31, 2020 in five major cities in Indonesia, namely Jakarta, Bandung, Yogyakarta, Semarang, and Surabaya. The data was processed using the fixed effect least square dummy variable (LSDV) model to test the impact of the PSBB policy or restrictions on citizen mobility to reduce the spread of COVID-19 on PM_2.5 concentrations.

As a result, the PSBB policy had a …

Assessing Public Health Benefits Of Replacing Freight Trucks With Cargo Cycles In Last Leg Delivery Trips In Urban Centers, Jennifer C. Hartle, Ossama (Sam) A. Elrahman, Cara Wang, Daniel A. Rodriguez, Yue Ding, Matt Mcgahan

Mineta Transportation Institute

Increased urbanization, population growth, and demand for time-sensitive deliveries means increased freight movement in cities, which contributes to emissions, noise, and safety concerns. One innovative mode gaining widespread attention for urban deliveries is cargo cycles—bicycles adapted for freight delivery. Despite the recognized potential and possible success of transporting at least 25% of freight via cycle, research remains limited. This research investigates the potential of cargo cycle delivery for last mile freight in Oakland, California, with a focus on the West Oakland neighborhood. The data collection included interviews, focus groups, vehicle field observation and counts, and traffic simulation modeling. The traffic …

Assessing Changes In Actual Air Quality And Public Perceptions Of Air Quality In Kathmandu Valley Nepal Pre And Post Covid-19 Lockdown, Robin Margherita Rives

USF Tampa Graduate Theses and Dissertations

Air pollution is a global concern. Cities around the world fail to meet air quality standards set by the World Health Organization Air Quality Guidelines, which has a significant impact on public health. As the capital city and largest metropolitan region of Nepal, Kathmandu is a hotspot for urban pollution in South Asia. Nepal faces emissions from both internal and external sources. External sources include emissions from Nepal’s neighboring countries of India and China and emissions resulting from tourism. Internal sources of pollution in the country include brick and cement factories, consumption of energy from traditional sources such as biomass, …

Reckoning With Induced Vehicle Travel, Jamey Volker

PSU Transportation Seminars

Empirical research shows that expanding roadway capacity induces more driving - the so-called "induced travel" phenomenon. However, environmental impact assessments and cost-benefit analyses of roadway capacity expansion projects have historically ignored, underestimated, or misestimated this induced travel effect. As a result, they frequently overestimate the projects' potential to relieve congestion and reduce air pollution. That spurred our team at the National Center for Sustainable Transportation (UC Davis) to develop an online tool to facilitate estimation of induced vehicle travel from capacity expansion projects. This presentation will explain the induced travel phenomenon, introduce our induced travel calculator and its offshoots, …

Does Air Pollution Cause Residents Of New Delhi, India To Migrate Internationally?, Snigdha Basu

Theses and Dissertations (Comprehensive)

Delhi, India, and the surrounding cities of Noida, Gurugram, Faridabad, and Ghaziabad consistently rank among the world's most polluted cities. For many parts of the year, air pollution levels are so high as to cause significant harm to human health, economy and the environment. Despite overwhelming evidence of the severity and consequences of air pollution, institutional measures to control it remain insufficient.

There is growing evidence that environmental degradation has the potential to generate migration of people out of affected areas. However, the links between environmental factors and migration are complex, with migration often being a result of interactions between …
