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.

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). 

In this essay the authors have highlighted some of the stakeholders in the fight against industrial biomass operations as members of the surrounding community who live with these operations as close as their own backyards, and experience the environmental pollution directly everyday. They highlighted Belinda Joyner, a resident of Northhampton County, and an environmental activist who rose to defend her community and their lands and livelihoods due to expanding hazardous infrastructures such as the Atlantic Coast Pipeline and the Enviva power plant. Other stakeholders besides activists and organziers such as Belinda include the people of Northampton County who attend hearings with government officials and take a stance agaisnt pollution, as well as organizations such as the Dogwood Alliance. The county is predominantly Black and working class, one of several in North Carolina that bear the brunt of exploittion and pollution by powerful biomass manufacturers such as Drax and Enviva.

This timeline essay provides more examples from recent years of community responses and collective action for environmental justice.

The development of both pipelines and CAFOs (confined animal feeding operations) in eastern NC have prompted action from justice organizations such as the North Carolina Environmnetal Justice Network (NCEJN). To address the ongoing problem of CAFOs, NCEJN has provided a number of resources on their site, as well as ways to take action by signing a petition to stop the use of hog waste as fertilizer. Prior to the Atlantic Coast Pipeline (ACP) being canceled in 2020, NCEJN played a role in organizing protests and taking legal actions- in conjunction with many other community member and activist groups- against Dominion and Duke Energy, the companies responsible for the ACP's construction. 

This study examined the risk of acquiring Ebola Virus Disease (EVD) by healthcare workers in the setting of general hospitals and isolation units. By looking retrospectively at the Ebola Outbreak in Sierra Leone, the relative levels of risk to healthcare workers were computed and compared. The reasoning for these levels was also examined through interviews of surviving workers and the families/associates/colleagues of the deceased workers. The interviews reviewed common actions (and lack there of) for affected workers. This revealed certain themes that should be visited when reveising/creating hospital infection prevention and control policies.

In the case of this study, the vulnerable population examined was healthcare workers in Sierra Leone during the outbreak. These workers were found to be at a significant level of risk for transmission for a number of reasons. These include proximity to the virus (due to the occupation), lack of training in the area of infection control, and cultural factors (such as prevalence of self-medication and home management of illness). Nurses as a whole were most affected, with over half of the infected members. 

The data acquired in this study can be used not only for improvement in policies and training for healthcare workers, but also to examine the risk factors for the disease. One example is the age and gender disparities in those nfected. These could be explained by the typical age and gender of healthcare workers, but could also show a trend in risk when coupled with patient data. The data on the districts and their infection rates can be used to help pinpoint the origin of infection. 

The study was published in BMC Infectious Diseases, a peer-reviewed journal on the prevention, diagnoisis, and management of infectious disease. The journal seems to be genrally well respected.

This was a retrospective study. While not the most accurate and well supported way to conduct a study, due to the effects of recall bias, it was really the only way to gain the data that was presented in the report. There isn't really anything new about the style of research.
