Indigenous Communities' Disproportionate Exposure to "Forever Chemicals"

ADDRESSING TOXIC RACISM: BILL C-226 AND INDIGENOUS COMMUNITIES’ DISPROPORTIONATE EXPOSURE TO “FOREVER CHEMICALS”

This blog was written by Lily Farinaccio as part of the Community Research Partnerships in Ethics (TRN407Y1) between Trinity College at the University of Toronto and WHEN under the supervision of Professor Nicole Spiegelaar. For the purposes of this blog post, the term “women” is used to describe those with ovarian reproductive systems. This is not to marginalize bodies that identify as women and do not possess these reproductive systems. Rather, it is intended to highlight how these chemicals differentially interact with certain bodies, creating sex-specific consequences.


Indigenous communities – particularly Indigenous women – face a disproportionate risk of exposure to “forever chemicals” and their health effects. Proposed Bill C-226 offers an important start to tackling cases of environmental racism such as this, but what is needed for its effective implementation?

WHAT IS ENVIRONMENTAL RACISM?

Environmental racism is a form of inequality whereby racialized communities are disproportionately impacted by polluting industries, toxins, and associated health conditions (Waldron, 2018). There are many instances of environmental racism in Canada. One example is the disproportionate exposure to per- and polyfluoroalkyl substances (PFAS), or forever chemicals, faced by Indigenous peoples. 

WHAT ARE PFAS?

PFAS are a group of thousands of synthetic chemicals with grease, heat, and water-resistant properties (Park et al., 2019). They’re used in various industrial applications and consumer products, including non-stick cookware, carpeting, apparel, upholstery, food packaging, firefighting foams, and personal care products (Park et al., 2019; Person and Renfrew, 2024). 

From an environmental health perspective, PFAS are strikingly troublesome. They resist natural processes of degradation and are persistent in the environment and the human body, earning the name forever chemicals (Garcia-Barrios, 2021). They’re also associated with a wide range of health effects, including: 

  • Endocrine, liver, and immunological effects 

  • Thyroid disease

  • Cancers

  • Developmental issues

  • Decreased fertility 

  • Asthma 

  • Decreased vaccine response 

  • Pregnancy-induced hypertension

  • Hypercholesterolemia 

  • (CELA, 2021; Pearson and Renfrew, 2024)

HOW ARE INDIGENOUS COMMUNITIES DISPROPORTIONATELY AFFECTED? 

While all Canadians are routinely exposed to PFAS, several studies have found elevated levels among Indigenous communities (Aker et al., 2023; Caron-Beaudoin et al., 2020; Caron-Beaudoin et al., 2019; Dubeau et al., 2022; Garcia-Barrios et al., 2021). For example, a recent study on First Nations communities in Québec found that concentrations of the forever chemical, perfluorooctanoic acid (PFNA), were 21 times higher than levels in the general Canadian population (Dubeau et al., 2022).

There are a number of potential reasons for these increased PFAS levels. Notably, the consumption of traditional foods such as fish and caribou has been highlighted as a primary exposure pathway for Indigenous communities. This is due to forever chemicals’ ability to bioaccumulate in marine and terrestrial food webs (Aker et al., 2023). 

Given that the consumption of traditional foods has been described as one of the strongest links between Indigenous culture, health, and their environments, the presence of PFAS in traditional food sources is significant: it forces Indigenous communities to make trade-offs between their culture and health. Not only are PFAS harming Indigenous bodies, they’re also forcing Indigenous peoples further from their culture. 

WHAT ARE THE SPECIFIC EFFECTS ON INDIGENOUS WOMEN? 

Forever chemicals are associated with sex-specific health effects. These include fertility complications, such as endometriosis, PCOS, and decreased fertility, as well as the development of melanoma and breast cancer (Cathey et al., 2023; Kim et al., 2020; Mancini et al., 2020; Omoike et al., 2021; Tsai et al., 2015). Given that Indigenous women are at increased risk of exposure to PFAS, they’re at even greater risk of suffering these severe and potentially lethal consequences.  

Indigenous women also bear a disproportionate burden in managing the transmission of PFAS and the related health problems. Mothers can transfer around 40% or more of their PFAS body burden to their infants. Forever chemicals can also be transmitted to children during breastfeeding (Rickard et al., 2022). What’s more, the presence and transmission of PFAS during pregnancy and infancy are associated with various health impacts in children, including suppressed immune responses during childhood, low infant birth weights, and neurotoxic outcomes, such as decreased executive function and lower verbal IQ (Caron-Beaudoin et al., 2020; Rickard et al., 2022).

WHAT IS BILL C-226? 

Bill C-226: An Act Respecting the Development of a National Strategy to Assess, Prevent, and Address Environmental Racism and to Advance Environmental Justice – introduced by Green Party MP Elizabeth May in February 2022 – is legislation targeted at addressing and preventing the unequal environmental harms racialized individuals currently face in Canada. As of October 2023, the bill completed its second reading in the Senate. Once it passes its third reading, it will require the federal government to create a national strategy to address environmental racism. The strategy would include a study investigating the links between race, socioeconomic status, and environmental risk, as well as possible measures to both prevent and address environmental racism. The bill also features a section on consultation, emphasizing that, in formulating the strategy, the Minister of Environment must consult with relevant stakeholders, including Indigenous peoples (Bill C-226). 

Bill C-226 marks an important step towards addressing environmental injustices that cause severe harm among racialized communities across Canada, such as the disproportionate PFAS exposure faced by Indigenous peoples and Indigenous women. Looking forward, it is crucial we think about how it can be implemented effectively. To learn more about WHEN’s recommendations pertaining to the National Strategy, we encourage you to review our submission to the Senate Committee on Energy, the Environment and Natural Resources.

HOW CAN WE EFFECTIVELY IMPLEMENT IT?

MEANINGFUL INDIGENOUS INVOLVEMENT 

To ensure Bill C-226’s efficacy, the involvement of Indigenous communities can’t be performative. When Indigenous peoples aren’t meaningfully involved in decision-making processes, it results in solutions imposed by outsiders that are both inappropriate for and unwelcomed by the community (Black and McBean, 2016). 

Three ways to foster meaningful engagement of Indigenous communities in Bill C-226’s implementation are to:

  • Address the power dynamics in policy making

    • In policy, there’s an inherent power differential between the Canadian government and Indigenous communities. Indigenous peoples are often one of the only Indigenous individuals in the room, working within a colonial government system (Fridkin et al., 2019). When applying Bill C-226, there’s a need to address the power imbalances between the Canadian government and Indigenous communities.

  • Move beyond tokenism

    • Within Canadian policy making, there’s a tendency for Indigenous communities to be involved in tokenistic ways (Fridkin et al., 2019). Meaningful Indigenous involvement in the implementation of Bill C-226 requires moving beyond tokenism and fostering engagement that’s Indigenous-led.

  • Incorporate traditional knowledge

    • Research shows that when traditional knowledge is included in policy development and implementation, it allows for Indigenous participation in decision-making, recognizes the inherent rights of Indigenous peoples, and helps move towards self-determination (Black and McBean, 2016). Traditional knowledge can be used alongside data collection in developing the national strategy, based on what Indigenous peoples consider appropriate.  

CONSIDERING INTERSECTING IDENTITY FACTORS 

In addition to the meaningful involvement of Indigenous communities, Bill C-226 must also consider the impacts of various identity factors, such as sex and gender. These factors intersect with experiences of environmental racism, as highlighted with the case of PFAS exposure among Indigenous women. Because a singular approach doesn’t take into account the disproportionate harm faced by certain individuals, it will limit Bill C-226’s ability to fully address environmental racism.
This can be avoided by applying Gender-Based Analysis Plus (GBA+). GBA+ is a framework used by the Canadian government to understand the potential impacts of a government initiative on a diverse range of individuals by taking sex, gender, age, disability, education, etc. into account (Acharya-Patel, 2022; Women and Gender Equality Canada, 2022). Using GBA+ when implementing Bill C-226 will make sure the national strategy doesn’t neglect how identity factors such as sex complicate experiences of environmental racism. Given the potential of Bill C-226, these recommendations are important to consider as it advances through the legislature.
