Outdoor and indoor particle air pollution and its health consequences in African cities: New evidence and an exhortation

Sustainable Environment, Journal Year: 2023, Volume and Issue: 9(1)

Published: Oct. 12, 2023

Particulate matter (PM) air pollution has been identified as the leading cause of disease burden in Africa. A greater understanding particle and its negative health effects is critical for developing effective long-term solutions to pollution. The current research on outdoor indoor concentrations their populated African cities was summarised this study. In academic databases, 71 articles published peer-reviewed journals between 2010 2023 were located, with 45 reporting PM 27 examining impacts exposure airborne particles. narrative synthesis technique used systematic review critically analyse provide descriptive summaries study findings tabular form. According study, most that assessed burdens focused either PM2.5 or both PM10. PM10 levels ambient home surpassed WHO-recommended threshold values.

Impact of biogas adoption on household energy use and livelihood improvement in Kenya: an overview on a roadmap toward sustainability

International Journal of Energy Sector Management, Journal Year: 2024, Volume and Issue: unknown

Published: Oct. 29, 2024

Purpose This study assesses the impact of biogas adoption on household energy use and livelihood improvement. Also, this aims to clarify benefits as a pathway sustainable energy. Design/methodology/approach The explored adopting uptake. Fourteen sustainability indicators were identified, validated categorized. Findings Adopting technology provides numerous benefits, including better air quality, reduced deforestation lower greenhouse gas emissions. Households can replace up 4.5 tons wood fuel, cutting CO 2 emissions by around 6.75 annually. shift saves approximately US$25 (Ksh.3223) monthly frees 45.5 h per week, enabling families pursue additional income-generating activities. Biogas also produces digestate, natural fertilizer that improves soil fertility, water retention reduces erosion while minimizing need for chemical fertilizers. Integrating in livestock housing odors, pathogens methane Research limitations/implications findings demonstrate social, economic environmental implications use. Social Health include exposure smoke particulate matter, particularly benefiting women children reducing respiratory issues, improving lighting enhancing educational opportunities. further hygiene, promotes cleanliness, strengthens security alleviates poverty. In addition, construction, operation maintenance systems create jobs, digestate enhances agricultural productivity. Originality/value unique thorough analysis biogas, offering valuable insights outlining approach.

The accumulation of potentially toxic elements (PTEs) in water, soil and vegetables can pose a severe threat to the respective organisms lead human health risks upon exposure. Water, vegetable samples were collected from Mokolo River its vicinity. Total concentration quantification speciation analysis chromium (Cr) arsenic (As) performed using inductively coupled plasma-mass spectrometry (ICP-MS) high-performance liquid chromatography hyphenated (HPLC-ICP-MS), respectively. total concentrations Cr As below maximum permissible levels (MPLs) set by World Health Organization (WHO) South Africa’s Department Water Affairs Forestry (DWAF) for drinking water. quality guideline value 64.0 µg/g was surpassed most sites posed great risk growing it, whereas 12.0 one sampling site. observed high could be linked use fertilizers atmospheric deposits introduced through coal burning power stations. In vegetables, recommended MPL 0.5 µg/g, rendering unsafe consumption. Concentrations ranging 197 1180 ng/g 374 17400 detected Cr(VI) Cr(III), consumption containing would result adults children as hazard quotient (THQ) exceeded 1. some particularly cause serious THQ > 10 Cr-contaminated vegetables. incremental lifetime cancer (ILCR) threshold 1 × 10−4 exceeded, indicating that overall had children.
