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.

In response to multiple concerns about water quality expressed by residents, EJCAN launched a water quality testing initiative with university-based collaborators from UNC Chapel Hill and Appalachian State University. Threats to water include but are not limited to industrialized agriculture. Industrialized hog feces contain pathogens, heavy metals, and antibiotic-resistant bacteria that growers store in large, open pit lagoons (Grant 1999; Wing et al. 2008; Blanchette 2019; Christenson et al. 2022). When operators spray the waste onto nearby fields, they also release air and waterborne contaminants. Scholars have linked airborne emissions from industrial hog operations to respiratory dysfunction, mood disorders, compromised immune function, anemia, kidney disease, tuberculosis, and low birth weight (Wing et al. 2000; Kravchenko et al. 2018; Guidry et al. 2018). Moreover, the odor is noxious, causing nausea, embarrassment, disorientation, and social loss in cultural continuity as people cease culturally meaningful practices like gardening, going for walks, or gathering outside to share food (Herring 2014; Blanchette 2019). The impacts to water include contamination, harmful algal blooms, fish kills, and eutrophication in rivers and estuaries, especially when hurricanes flood the inner coastal plains with industrialized animal waste (Wing et al. 2000; Wing et al. 2008; NCCN 2021; Emanuel 2018; Christenson et al. 2022). Access to water infrastructure in Sampson County is highly uneven, and residents have been advocating for improved access for more than a decade.

In response to concerns expressed by community members, EJCAN launched a water quality testing initiative with university-based collaborators to increase knoweldge about the impacts of multiple hazards on water. Industrialized hog feces contain pathogens, heavy metals, and antibiotic-resistant bacteria that growers store in large, open pit lagoons (Grant 1999; Wing et al. 2008; Blanchette 2019; Christenson et al. 2022).

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.

A variety of sources were used to make this article, as seen in the bibliography. The authors referenced many US government documents, news and research articles, recovery programs, research on other disasters, and various other works. This shows that the authors were not narrow-minded in their research, they looked for many points of view and other evidence for the article.

The article looks at the "chronic disaster syndrome" - consisting of a multitude of factors that all act upon a person or family after a disaser like Katrina. The aftermath of the distaster lasts years, and this can wear on one's health if they are unable to return to their normal lives. Being displaced for a long period of time, in less optimal conditions, in a new environment, with new schools and jobs, can be traumatic

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.
