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 this article emergency response in addressed in the sense that if preemptive measures are not taken and the socioeconomic factors preventing care are not taken into consideration the United States and the world is at risk of a pandemic. If this occurs, there is uncertainty in what the appropriate response would be as the scale and complexities of the biological agent will be unknown.

“Chronic disaster syndrome” thus refers in this analysis to the cluster of trauma-and posttrauma-related phenomena that are at once individual, social, and political and that are associated with disaster as simultaneously causative and experiential of a chronic condition of distress in relation to displacement.  "

“ Living with long-term stress related to loss of family, community, jobs, and social security as well as the continuous struggle for a decent life in unsettled life circumstances, they manifest what we are calling ‘chronic disaster syndrome.’”

“One of the recurring themes that we heard from those who were still displaced in trailers or temporary living situations (e.g., with relatives), but more so from those who had returned and were, in a few cases, back in their homes, was that, even if the neighborhoods were being rebuilt, people had lost so much that nothing would never be the same.”

When I see the movie, I was questioned that are the MSF are always keep helping one areas, and how long they can help. After research, I have found the projects that MSF closed are depends on the specific project and it is always a difficult decision. For example, some projects in Liberia are closed because of after many years, they had improved the emergency and health services.

There are also Medical issues offer by MSF, and they provide services within basic vaccination, maternal, pediatric care, fighting neglected diseases and complex surgery.

There are many ways to support MSF, within Foundation support, corporate support and so on.

The main argument Knowles develops in this article is structural and engineering integrity of buildings and equipment is not always questioned until a disaster occurs and there is public outcry for regulations to be put in place. Whereas if building codes and safety equipment was being regularly tested and enforced, when disasters occured they would not be as tramatic.

The law has signed for emergency triggers financial and physical assistance through the FEMA. It is also funding for training as agency’s preparedness effort. It shapes the way of prepare for hazards, and make a better intergovernmental coordination.

"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."
