“…The contribution of anthropogenic activities such as industrial activities to pollution is rarely investigated in Rwanda. Air pollution was observed around the Chimerwa area, but how the industries managed wastewater was not discussed, and the tailings may be a route towards the discharge of contaminants and, hence, pollution [79,80]. The performance of the Kacyiru Sewage Treatment Plant, and the impact of its effluents on the receiving wetlands, was investigated.…”

A Review on Contaminants of Emerging Concern in the Environment: A Focus on Active Chemicals in Sub-Saharan Africa

Active chemicals are among the contaminants of emerging concern that are rarely covered in regulatory documents in sub-Saharan Africa. These substances are neither in the list of routinely monitored substances nor in the guidelines for routine environmental monitoring activities. This has been of concern to public health officials, toxicologists, communities, and governments, hence the need for risk assessment and regulation of these substances. In this review article, the presence of active chemicals in the sub-Saharan African environment was investigated. The results indicate the availability of few studies in some countries, while in other countries no reports of active chemicals were found, hence the need for further research targeting such countries. It was further observed that mixtures of active chemicals from different therapeutic categories—such as antibiotics and analgesics—were reported. The natural environment is increasingly at risk due to the presence of these substances, their metabolites, and their transformation byproducts. These substances are characterized by persistence as a result of their non-biodegradable nature; hence, they circulate from one environmental compartment to another through the food chain, causing harm along the way. Most studies that evaluated the toxicity of these substances considered the effects of a single drug, but observations indicated the presence of drug mixtures, hence the need for further evaluation of the effects of drug–drug interactions—including synergistic and additive effects—for environmental sustainability. The presence of ACs in several environmental compartments at quantifiable quantities was discovered in this investigation, indicating the potential for ecosystem injury as a result of bioaccumulation, bioconcentration, and biomagnification through the food chain. This necessitates further research on the subject in order to ensure a healthier environment.

“…Currently, particulate matter pollution is considered an important point of concern in developing countries due to its negative health effects. In Rwanda, a few studies concerning air quality have shown that particulate matter, sulfur oxide (SOx), nitrogen oxide (NOx), and ozone O3are the most common pollutants in disquiet countries (Irankunda. & Ishigaki, 2020).…”

Considerable efforts have been made to protect people from indoor air pollutant exposure as approximately 80% of people spend time indoors where pollution is often worse than outside. Further, vulnerable populations, including elderly, children, and pregnant women, spend an excessively of time indoors, exposing them to pollutants that are responsible for both short-term and long-term negative health effects, resulting an estimated 4 million premature deaths annually. Aim of this research was to assess impressions of domestic use of solid fuels (firewood and charcoals) burning on Particulate Matter PM2.5 and PM10, which are particles that are less than or equal to 2.5 and 10 micrograms (μm) in diameter respectively within Kigali the capital city of Rwanda. A sample of 31 households using only charcoals and woods for cooking were selected for targeted 72 hours of monitoring. Portable air quality sensors AirVisual Nodes were used to measure concentration levels of PM2.5 and PM10 in microgram per cubic meter (μg/m3). Results showed that homes using wood for cooking experience moderately high concentrations level of PM2.5 and PM10, over 1000 μg/m3 and 1200 μg/m3 respectively, whereas homes using charcoals for cooking had lower concentrations. This later direct to that: Outstanding to low market prices of these solid fuels, poorer households are highly exposed to indoor air pollution. So, an alternative reasonably priced domestic energy to be used for cooking are indorsed and pollution levels survey in households using combination or different types of fuels for cooking are recommended for future research. Contribution/Originality: The paper's primary contribution is that: • Households using woods and charcoals for cooking activities are exposed to high air pollution levels. • An alternative reasonably priced domestic energy to be used for cooking should be used as a primary energy for cooking. 1. INTRODUCTION Particulate matter the complex mixture of small particles and liquid droplets, which includes organic chemicals, metals, acids, and dust particles considered to be among the major air pollutants of concern (Global Burden of
