“Since asthma surveillance data were not available at the census tract level for most of Louisiana, we estimated asthma burden using the inpatient discharge data available through LDH.”  (4)

“Case counts are not provided for CTs with a 2018 population of less than 800 to safeguard privacy.” (4)

“To minimize the need for suppression, inpatient discharge data was aggregated for the three most recent years available (2017–2019) and average annual crude rates were calculated for cases where asthma (ICD-10 code J45) was the primary diagnosis, as well as where asthma was any diagnosis.” (4)

“Spearman’s Rank Correlation was utilized to analyze the correlation between various social and environmental vulnerability factors, COVID-19 incidence, and the measures of asthma risk by CT.” (4)

“This was performed by first ranking the values in each dataset using RANK.AVG function in MS Excel 2016, followed by applying the PEARSON function to compare two datasets. Significance was set at alpha less than 0.05 (α < 0.05), with degrees of freedom (df) equal to two less than the total number of data points represented in both datasets” (4)

The research team works for the Section of Environmental Epidemiology and Toxicology, Office of Public Health, Louisiana Department of Health in Baton Rouge. Team members included Arundhati Bakshi; Shanon Soileau; Collete Stewart; Kate Friedman; Collete Maser; Alexis Williams; Kathleen Aubin; and Alicia Van Doren. 

“Currently, much of the environmental focus of the pandemic remains on PM2.5 levels; however, we noted that higher levels of ozone was consistently associated with higher incidence rates of COVID-19, and it was the only environmental factor that appeared to have an additive effect over SVI on COVID-19 incidence (Fig 1).” (11)

“Specifically, our data show a moderately strong positive correlation between SVI due to minority status/language barrier and three health data variables: asthma hospitalization; estimated asthma prevalence; and cumulative COVID-19 incidence at 3 months (Table 2). Interestingly, SVI measures were either negatively or not significantly correlated COVID-19 incidence at the 9-and 12-month time points, indicating that social vulnerability factors may have played a greater role in COVID-19 spread early in the pandemic, but may have been of diminishing importance as the pandemic wore on (Fig 1 and Table 2).” (9)

This document uses data resources from the Center for Disease Control/Agency for Toxic Substances and Disease Registry (CDC/ATSDR), the Environmental Protection Agency (EPA), and the Louisiana Department of Health (LDH).

These data resources include the Social Vulnerability Index (2018 - CDC/ATSDR), the NATA Respiratory Hazard Index (EPA 2014), PM2.5level (average annual concentration in ug/m3, EPA 2016), ozone level (summer seasonal average of daily maximum 8-hour concentration in air in parts per billion, EPA 2016), indoor mold concerns reported to IEQES program (average annual number of calls, LDH 2017-2019), cumulative COVID-19 incidence rate at 3-, 6-, 9- and 12-month increments (LDH March 2020 - March 2021), asthma hospitalization (average annual crude rate, where asthma was a primary diagnosis among hospitalization cases, LDH 2017-2019), and estimated asthma prevalence (average annual crude rate, where asthma was any diagnosis among hospitalization cases, LDH 2017-2019).

Given the vastness of Formosa Plastics' influence, there are many ways to tell its story to the world. As environmental justice activists and researchers, how do we describe a company and its negative impact when there is so much to say? Limited by time, word count, and the audience's attention span, we must decide what goes unsaid. As a result, we could write countless answers to the same question, "What is Formosa Plastics?"

In this published academic case study, I introduce Formosa Plastics through a local lens--specifically, through the eyes of a grandmother-turned-activist in the small town of Welcome, Louisiana. Her family's history with social justice activism, as well as the area's connection to centuries of slavery, make the environmental racism of Formosa Plastics' Sunshine Project especially salient. Although Formosa Plastics is a global force, telling its story on the microscale is an equally important perspective. After all, in Sharon Lavigne's eyes, her small town is her world. How many of these little worlds have Formosa Plastics destroyed as they wreak havoc across international borders?

This epi study looks at multiple organizations that have put together data regarding the respiratory health changes of individuals that were directly affected by destruction of the WTC in 2001. It proposes the problems that are faced by those individuals and the difficulties of treating them and acquiring data about them. This data will not only help these individuals with treatment and education, but can also help with plans for future care if this kind of thing is unfortunately ever to happen again.

This study is published in Disaster Medicine and Public Health Preparedness (DMPHP).  DMPHP is a journal that is focused on emphasizing public health preparedness and disaster response for all health care and public health professionals globally. Using scientific information that they've gathered, they make it accessible and understandable from medical and public health perspectives. As per the title they study many emergency situations such as 9/11, H1N1, and Katrina.

"The role of epidemiology in disaster response policy development" cites this epi study. This article addresses the role of epidemiology in informing policies after a disaster to mitigate ongoing exposures, provide care and compensation, and improve preparedness for future disasters. It uses our article to support the argument that epidemiology should be used for prep for disaster.

Professionals can use this information of affected individuals in order to designate their post event focus on care for emergency providers.
