Assessment of the health impacts of air pollution exposure in East African countries.

The health effects of air pollution remain a public concern worldwide. Using data from the Global Burden of Disease 2019 report, we statistically analyzed total mortality, disability-adjusted life years (DALY), and years of life lost (YLL) attributable to air pollution in eight East African countries between 1990 and 2019. We acquired ambient ozone (O), PM concentrations and household air pollution (HAP) from the solid fuel from the State of Global Air report.

Polyoxometalate-catalyzed hydrolysis of the hemicelluloses by (Mo-V-P)-heteropolyacids-Statistical modeling using response surfaces.

The mixed-addenda Keggin-type molybdovanadophosphate heteropolyacids (Mo-V-P)-HPAs of series H[PMoVO] with n = 3,4 (HPA-3 and HPA-4) were found to be extremely effective acid catalysts for green hydrolytic conversion of plant (wood and agro-crop) hemicelluloses into soluble mono and oligosaccharides (XOS) within an integrated biorefining scheme. Response surface methodology (RSM) has been applied for statistical modeling and optimization of (Mo-V-P)-HPA catalyzed hemicellulose hydrolysis using potential European energy agro-crop giant reed (Arundo donax) as a model lignocellulosic feedstock. In much diluted (0.
