Public health research suggests that children exposed to localized air pollution may suffer from cognitive impairment during testing or chronic conditions such as asthma that could influence their academic performance. After controlling for the appropriate confounding variables, our findings indicate that a 1-unit increase (or an equivalent one-third increase in the standard deviation) in the average amount of particulate matter observed over the past 6 years in a school district reduces the average standardized test score by about 4%. In addition, a typical student in a California school district in the two highest quintiles of PM 2.5 exposure (controlling for other causal factors) exhibits standardized test scores closer to the fifth-grade equivalency level than the sixth.

We searched PubMed for studies that were (1) peer-reviewed; (2) written in English; (3) quantitatively measured environmental exposures; (4) included 1 or more groups identifying as a sexual minority, gender minority, or both; (5) compared to the general population; (6) in the United States; and (7) published on or after January 1, 2011. Our scoping review identified very few studies that examined and documented environmental exposure disparities between SGM and non-SGM populations in the United States. These studies focused mostly on cigarette smoke exposures. None examined environmental exposure disparities between gender minority and cisgender populations. To address this critical gap in environmental health research for SGM populations in the short term, researchers can merge existing environmental data (eg, data from the Environmental Protection Agency) with SGM population data. Longer-term solutions require systematically including validated sexual orientation and gender identity measures across federal, state, and local datasets, as well as increased funding for original research that explores diverse environmental exposures.

Wastewater treatment plays a crucial role in safeguarding the environment, public health, aquatic organisms, and water resources, reducing environmental impact, and adhering to regulations. However, the current methods for treating wastewater in Africa fall short of these goals, resulting in substantially poor environmental and health outcomes and inadequate provision of safe water and essential sanitation. Poor wastewater management in several African countries has led to severe health risks for humans, animals, and aquatic ecosystems. This poses a particular threat to vulnerable groups like children, women, and the disabled residing in rural and remote areas with limited access to healthcare. Hence, this article aims to shine a spotlight on the difficulties in managing wastewater in Africa and to recommend several plausible strategies to tackle this issue. A literature search to find the most recent and relevant research papers from various databases, such as Scopus, Web of Science, PubMed, and Google Scholar, along with resources from the World Health Organization, was conducted. The selection criteria focused on including the most recent and relevant publications published in English to facilitate comprehension, analysis, and interpretation of the secondary data. Essentially, addressing the challenge of wastewater management in Africa requires developing indigenous innovative technologies, transitioning to a sustainable economy, establishing wastewater treatment infrastructures in rural and remote areas, enhancing operation and maintenance practices, training treatment facility workers, improving electricity supply, strengthening government participation and support, encouraging public involvement, setting local water quality benchmarks, and international financial and technical support.
