The Ramapough Lunaape Nation: Facing Health Impacts Associated with Proximity to a Superfund Site

Contaminated sites and Indigenous peoples in Canada and the United States: A scoping review

Indigenous communities are disproportionately exposed to contaminated sites, and this poses unique challenges as many Indigenous peoples consider land as an integral part of their culture and economy. This scoping review aimed to identify and map information on contaminated sites and Indigenous peoples in Canada and the United States, namely (1) the relationship between contaminated sites and Indigenous peoples and their land and food systems; (2) strategies, challenges, and successes for contaminated sites assessment and management on Indigenous land; and (3) Indigenous leadership and inclusion in contaminated site assessment and management. We followed a PRISMA-ScR (Transparent Reporting of Systematic Reviews and Meta-Analyses-Extension for Scoping Reviews) checklist to collect data that could be categorized into these three objectives. Between October 2021 and July 2023, information from three data streams was retrieved: a systematic literature search; a grey literature search; and federal site data retrieval (Canada's Federal Contaminated Sites Inventory, USEPA's contaminated sites databases, including Superfund). This search yielded 51 peer-reviewed articles, 21 grey literature articles, and 11 404 federal site records, evidencing the contamination of the lands of 875 Indigenous communities and the presence of 440 different contaminants or contaminant groups. The body of information was categorized into three themes within the above objectives: Objective 1: Indigenous communities and geographic patterns; Contaminated sites, sources, and media; Contaminated sites and Indigenous lands; Contaminated sites and Indigenous food systems; Contaminated sites and the health of Indigenous peoples; Objective 2: Site management and classification processes; Health risk assessment; Risk management; Long-term management; and Objective 3: Collaborative research, Collaborative site management; Traditional knowledge and contaminated sites. Results highlighted a need to prioritize holism, efficiency, and Indigenous leadership in site assessment, management, and research, including a focus on community-specific approaches to site assessment and management; a reconceptualization of risks that privileges Indigenous epistemologies; and greater collaboration between stakeholder networks.

Diabetes quality of life, Chemical Intolerance, and generational status in a Latino sample: an RRNeT study

Objectives

The impact of diabetes on quality of life (QoL) includes deficits in physical functioning and emotional and mental health. Individuals with diabetes can experience significant distress related to diabetes management and burden. Comorbid conditions can contribute to QoL among individuals with diabetes. Chemical Intolerance (CI) has received minimal attention in the context of diabetes. CI is characterized by multi-systemic symptoms initiated by a one-time high dose or persistent low-dose exposure to environmental toxins. Latinos experience diabetes distress and are exposed to environmental factors at disproportionate rates. This study sought to investigate generational differences in diabetes QoL and CI in a Latino sample across generational status.

Methods

To assess the modifying effect of CI between QoL and generations, the analysis was stratified by those with and without CI.

Results

Compared to 2nd generation Latinos, Latino immigrants were more likely to indicate that without diabetes, their life would be better across several QoL domains. Latino immigrants had a lower A1C and BMI than2nd generation Latinos. Additionally, they were less likely to have scores indicative of CI than U.S.-born Latinos. QoL varied by generational status and suggested a greater emphasis on family and social relationships among immigrants than U.S.-born Latinos. There were no differences in health services measures across generations.

Conclusions

This study highlights generational differences in the impact of diabetes on QoL. It is one of the few studies to seek to understand the impact of CI on QoL in the context of a chronic condition such as type 2 diabetes.

Exposure Routes and Health Risks Associated with Pesticide Application

Pesticides play an important role in agricultural development. However, pesticide application can result in both acute and chronic human toxicities, and the adverse effects of pesticides on the environment and human health remain a serious problem. There is therefore a need to discuss the application methods for pesticides, the routes of pesticide exposure, and the health risks posed by pesticide application. The health problems related to pesticide application and exposure in developing countries are of particular concern. The purpose of this paper is to provide scientific information for policymakers in order to allow the development of proper pesticide application technics and methods to minimize pesticide exposure and the adverse health effects on both applicators and communities. Studies indicate that there are four main pesticide application methods, including hydraulic spraying, backpack spraying, basal trunk spraying, and aerial spraying. Pesticide application methods are mainly selected by considering the habits of target pests, the characteristics of target sites, and the properties of pesticides. Humans are directly exposed to pesticides in occupational, agricultural, and household activities and are indirectly exposed to pesticides via environmental media, including air, water, soil, and food. Human exposure to pesticides occurs mainly through dermal, oral, and respiratory routes. People who are directly and/or indirectly exposed to pesticides may contract acute toxicity effects and chronic diseases. Although no segment of the general population is completely protected against exposure to pesticides and their potentially serious health effects, a disproportionate burden is shouldered by people in developing countries. Both deterministic and probabilistic human health risk assessments have their advantages and disadvantages and both types of methods should be comprehensively implemented in research on exposure and human health risk assessment. Equipment for appropriate pesticide application is important for application efficiency to minimize the loss of spray solution as well as reduce pesticide residuals in the environment and adverse human health effects due to over-spraying and residues. Policymakers should implement various useful measures, such as integrated pest management (IPM) laws that prohibit the use of pesticides with high risks and the development of a national implementation plan (NIP) to reduce the adverse effects of pesticides on the environment and on human health.
