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.

Staßfurt, Saxony-Anhalt Environmental health threats

Philipp Baum

1. Long-term threats, legacy of mining
- Unstable old salt mines below Stassfurt that have to be monitored and water flows have to be management to prevent ground movement
- so far, more than 800 buildings, including an 500-year old church had to be demolished. Currently, ground movement is under control
- 27 waste heaps and contaminted sites within the city that contain many very hazadous chemical compunds. They were never properly cleaned up

2. Long-term threats, ongoing causes
- by-products of salt mining and refining are collected in large landfills that leak salt into sorrounding areas. There are no plans how these landfills can be remediated, they have to be mananged indenfinitely
- soil erosion of arable land around the city by high intensity farming of crops for livestock production and bioenergy
- toxic waste produced by waste incarceration plant is pumped into former salt mining caves where it solidifies and becomes impossible to recover

3. Short term threats
- explosion in bionenergy plant in 2020
- leakage of ammonia at public street in 2014
- pollution of river bode with ammonia and chloride by CHIECH Soda, massive fish kills every summer
- air pollution, cause unknown, probably mostly by metalworks industry

Staßfurt, Saxony-Anhalt Setting: Salt-mining

Philipp Baum

Staßfurt is a small city in the East German Bundesland Saxony-Anhalt with about 24 thousand inhabitants. Like many cities and villages in the area, it faces huge demographic problems: The population is shrinking rapidly, consists mostly of older people, unemployment is high, percentage of highly educated people is low. The city has a long history of salt mining that goes back to the 13th century. Many inhabitants proudly refer to Staßfurt as the "Cradle of potash-mining" ("Wiege des Kalibergbaus"). Unfilled salt mining shafts that were flooded by groundwater had to be abandoned and started to cave in. Over 800 buildings in the city center had to be demolished because of instabilities, among them a 500-year old church. Nevertheless, salt mining and a metallic industry that developed alongside it is still the largest economic sector in Staßfurt. The city is still permeated by an old mining culture that becomes visible in traditional festivals, clubs (Bergmannsverein e.V. Staßfurt) and the playing of traditional miner's song on offical occasions (Steigerlied).

The main finding or argument of this article is that a patient's culture will significantly impact a patient's narrative and description of their medical history. Each culture has its own stigmas and norms that can affect the way a patient views their own medical history. This is an important thing that doctors should recognize when analyzing and assessing a patient's situation and history. Also, there is discussion about how an illness can impact an individual physically, mentally, socially, and otherwise. Public perception is an important part of this article.
