Harmful PM2.5 emissions in Dhaka, Bangledesh prompting researchers to study emissions during winter and monsoon season.
helena.davAssessing 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
helena.davThe 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.

jaostranderKnowles supports this argument through his investigation and presentation of three historical disasters that occurred in the United States. The disasters he chose included a structural integrity factor and a general malfunction or misuse of safety equipment. Knowles also discussed policy that resulted because of these disasters. The argument is also supported through his discussion of the events that occurred post 9/11 and the public out cry from that event as well. Knowles discusses the investigation after theses events occurred and how often times there is a lot of opinions and findings as to what the cause of the disaster or equipment failure was.

jaostrander"These studies can help us understand what factors are associated with different courses of mental illness, which can help us identify the most vulnerable populations and inform tailored interventions"
"Exposure to potentially traumatic events is disaster-specific and often measured differently between studies, making it difficult to compare experiences and mental health consequences or to generalize findings to all disaster-affected populations (22). Additionally, most instruments that assess symptoms of mental disorder have been developed and validated in the United States (23, 48) and may lack cultural relevance and validity in areas impacted by disasters worldwide"
"Persons who live in a community where a disaster has occured may differ in their degree of exposure in the event. They may be affected directly, being present at the disaster site, or indirectly, having loved ones present at the disaster site or seeing images of the disaster in the media."
