Assessing the PM2.5 impact of biomass combustion in megacity Dhaka, Bangladesh - PubMed (nih.gov)

This article is about crop burning in Dhaka, Bangladesh and attempts to figure out if there is more or less harmful PM2.5 particulate air pollution caused by either fossil fuels or biomass, and during which season is one or the other higher in the air pollution it produces. During monsoon season, fossil fuels lead in the most PM2.5 releases at 44.3%. When it is not monsoon season and is the winter season, the percentages are way higher for PM2.5 air particulate releases at 41.4% for the remainder of the year. Across the globe, there are now people stepping up to uncover the true and real environmental and health impacts this harmful particulate byproduct causes in different parts of the world and with differring weather conditions than what we see in North Carolina. 

Emissions from Biomass Burning in South/Southeast Asia; correcting the miscalculation about the PM2.5 emissions from burning.

This study is set in South/Southeast Asia and uncovering that, when trying to count the percentages of PM2.5 put off during biomass, the true amount of emissions were being gravely undercalculated. Specifically rice straw burning becuase the amount burned varied so much because of different harvest and burning practices that it just wasn't taken into consideration. What this study does is go bottom up using these strategies: "subnational spatial database of rice-harvested area, region-specific fuel-loading factors, region, and burning-practice-specific emission and combustion factors, including literature-derived estimates of straw and stubble burned"(Lasko et al. 2021, 1). 

The Clean Air Act and the EPA laws and regulations against harmful PM2.5 air pollutant matter

The most common air pollutants are called criteria pollutants and are regulated by the Clean Air Act and the EPA. These pollutants are: particles, ozone, nitrogen oxides, sulfer dioxide, carbon monoxide, and lead. The EPA have sections under the CAA that help regulate factories and air pollution in the environment. For example section 108 requires the EPA to identify the pollutants that are criteria pollutants, listed above, and determine if where they are coming from and if they "endander public health or welfare". Under section 109 the EPA had to set standards across the board for air pulltion in regard to human health and to the environemtn sperately (Christopher D. Ahlers 2016, 51-52).  There are many more sections that go into detail about what the CAA can do and what the EPA members are required to do as well.

Lee argues that EJ practice has long stagnated over an inability to properly define the concept of disproportionate (environmental and public health) impacts, but that national conversations on system racism and the development of EJ mapping tools have improved his outlook on the potential for better application of the concept of disproportionate impact. Lee identifies mapping tools (e.g. CalEnviroScreen) as a pathway for empirically based and analytically rigorous articulation and analysis of disproportionate impacts that are linked to systemic racism. In describing the scope and nature of application of mapping tools, Baker highlights the concept of cumulative impacts (the concentration of multiple environmental, public health, and social stressors), the importance of public participation (e.g. Hoffman’s community science model), the role of redlining in creating disproportionate vulnerabilities, and the importance of integrating research into decision making processes. Baker ultimately argues that mapping tools offer a promising opportunity for integrating research into policy decision making as part of a second generation of EJ practice. Key areas that Lee identifies as important to the continued development of more effective EJ practice include: identifying good models for quantitative studies and analysis, assembling a spectrum of different integrative approaches (to fit different contexts), connecting EJ research to policy implications, and being attentive to historical contexts and processes that produce/reproduce structural inequities.

The main arguments presented in this article is the history of disasters in the United States and the cause of buildings’ demise due to structural discrepancies. The historical accounts of the burning of the capital and the Iroquois theatre fire show how disaster investigation started and then evolved to the investigation of 9/11.

The methods, tools and data used to produce the claims in the article include: creating an argument- having separate sections of the paper: a cause, an effect and the resounding outcome. The authors created a story through describing the horrible accounts of what happened during and after Katrina. The cause is the hurricane which caused displacement of most of the population due to the flooding from the broken levee. This caused the government to hire outside resources to house and “collect” citizens. This ultimately caused rent to increase,=, and pushed the poor out of New Orleans. Through developing a solid argument; the paper gains credibility. The claims were also supported through direct quotes and government statistics.

The only reference to emergency response is that during the flooding, people were rescued from top floor apartments on rafts by neighbors, not by police or other safety officials. The article mostly deals with recovery from emergencies with national and state organizations and policies.
