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.

It used recording data for 455 married or cohabiting persons who were from 23 counties of Mississippi at the time of Hurricane. There are also a highly experience epidemiological survey team and seven local interviewers who underwent training in general techniques participated the interviews. The study was approved by an Institutional Review Board. The data was measured using the PTSD module of the Composite International Diagnostic Interview for the Diagnostic and Statistical Manual of Mental Disorder. Following the reference, it was modified in connected to the Hurricane Katrina.

Indian Point Energy Centre is a new power plants station in Buchanan. As well as the communities around it are without any emergency respond plants to nuclear disaster. NRC is  Nuclear Regulatory Commission, which is an organisation for the safety of nuclear power production and civilians uses for nuclear materials. In addtion, there are some representors of different communities. For example, Ben Smilowitz who is executive director of the Disaster Accountability Project, and Dutchess County’s commissioner of emergency response,Dana Smith. Some actors' words are quotated to show the main point of the article and support the author research.

This concept design is create a market which is within more functions and technologies for guardrail. In the existing market, there are some good design highway guardrail, such as EZY-guard smart guardrail. Most of the existing product are applied outter shapes and physical structures rather than some electrical technology. Compare to the existing products, this concept design is more challenged by the cost.
