Residents of Love Canal, in the Niagara Falls region of Western New York, were alerted to signs of a toxic waste crisis involving the lethal chemical byproduct dioxin in the late 1970s. Residents learned about the crisis through news media, community activism and research, and their own visceral experiences – they could smell noxious fumes, noticed black sludge seeping into their basements, and saw children falling ill. Activists and academics carried out community-based research to survey the area in an effort to understand the extent of the hazard and its effects – data that they saw as missing, at the time – in turn generating evidence of changes in health and pregnancy abnormalities. In doing so, members of the community aimed to hold corporate and government stakeholders accountable to evacuate residents, organize remediation, and strengthen scientific studies and interventions to care for residents. Regional health authorities, however, dismissed community-based studies as “useless housewife data”. Activists responded by scrutinizing government and scientific studies, critiquing a lack of ecological validity and trustworthiness. Residents and community groups’ advocacy contributed to their exercise of epistemic authority, the creation of archival records and initiatives tracking the crisis over the last five decades, and wider public attention to Love Canal and other sites like it.

Studie provides visual representations of lead concentration in Santa Ana cross matching it with vulnerability risk.

“Also of note when interpreting our results is that this study did not take into consideration the ingestion of heavy metals through the dietary route. Had we considered this additional exposure pathway, our calculated chronic daily intake levels of heavy metals would have been greater, resulting in higher estimated risk (particularly for metals such as Pb, As, and Cd which have been widely documented in various foods)” (Marsi et al. 2021)

“Both cancer and non-cancer risk at the Census tract level exhibited positive correlations with indicators of social as well as physiological vulnerability” (Marsi et al. 2021)

Exposure to heavy metals has been associated with adverse health effects and disproportionately impacts communities of a lower socio-economic status.  

This study used a community-based participatory research approach to collect and analyze a large number of randomly sampled soil measurements to yield a high spatially resolved understanding of the distribution of heavy metals in the Santa Ana soil, in an effort to exposure misclassification. This study looks into average metal  concentrations at the Census tract level and by land use type, which helps map potential sources of heavy metals in the soil and better understand the association between socioeconomic status and soil contamination (Marsi et al. 2021). 

In 2018, soil samples of eight heavy metals including lead (Pb), arsenic (As), manganese (Mn), chromium (Cr), nickel (Ni), copper (Cu), cadmium (Cd), and zinc (Zn) were collected across Santa Ana. These were analyzed at a high resolution using XRF analysis. Then, metal concentrations were mapped out and American Community Survey data was used to assess the metals throughout Census tracts in terms of social and economic variables. Risk assessment was conducted to evaluate carcinogenic risk. The results of the concentrations of soil metals were categorized according to land-use type and socioeconomic factors. “Census tracts where the median household income was under $50 000 had 90%, 92.9%, 56.6%, and 54.3% higher Pb, Zn, Cd, and As concentrations compared to high-income counterparts” (Marsi et al. 2021). All Census tracts in Santa were above hazard inder >1, which implies non-carcinogenic effects, and almost all Census tracts showed a cancer risk above 104, which implies greater than acceptable risk. Risk was found to be driven by childhood exposure.

It was concluded that the issue of elevated soil contamination relates back to environmental justice due to overlap between contaminated areas and neighborhoods of lower socioeconomic status. Marsi et al. (2021) found there needs to be more community-driven recommendations for policies and other actions to address disproportionate solid contamination and prevent adverse health outcomes.

As outlined in this brief article by the U.S. Energy Information Administration, energy consumption by New York City alone has dropped significantly more than the surrounding areas. On a prima-facie observation, one could say the foregoing alleviates stress on the existing energy infrastructures. However, deeper analyses should consider the repercussions that demanding less energy may have on production, supply, and distribution, as well as transitions between larger and smaller electric microgrids. Given energy infrastructures in the United States are already vulnerable, can it be really said the pandemic alleviates stress on the existing energy infrastructures when everybody is connected to the internet and is generally using more technology at home?
