spelling Chemical characteristics of bottom ash from biomedical waste incinerators in GhanaBiomedical waste (BMW)IncineratorBottom Ash (BA)Heavy metalGhanahttps://v2.sherpa.ac.uk/id/publication/15706Biomedical waste (BMW) incineration is the most used alternative disposal method in developing countries, such as Ghana. The improper disposal of incinerator-generated bottom ash (BA) is a significant concern due to the hazardous nature of waste. A study was conducted at Tema Hospital (TGH) and Asuogyaman Hospital (VRAH) incinerator sites. The BA samples were sent to the Council for Scientific and Industrial Research, Institute of Industrial Research, Ghana. The BA samples were weighed with fisher analytical balance, ground, and sieved with standard grade meshes of 120, 100, and 80 to determine the BA particle size distribution. The chemical composition and heavy metals were analysed using X-ray fluorescence spectrometry (XRF) and atomic absorption spectroscopy (AAS) techniques. The results indicated the chemical composition of the analysed BA samples was CaCO3 (49.90%), CaO (27.96%) and MgCO3 (6.02%) for TGH and CaCO3 (48.30%), CaO (27.07%), and SiO2 (6.10%) for VRAH, respectively. The mean concentration (M) (kg m−3) and standard deviation (SD) for TGH in the BA were 7.082 ± 0.478 (Ti), 4.657 ± 0.127 (Zn) and 4.271 ± 1.263 (Fe), while that of VRAH consisted of 10.469 ± 1.588 (Ti), 7.896 ± 2.154 (Fe) and 4.389 ± 0.371 (Zn). Therefore, the heavy metals’ mean concentration at the BA is above the WHO permissible limits of soil, i.e., 0.056 kg m−3 (Ti), 0.085 kg m−3 (Pb), 0.100 kg m−3 (Cr) and 0.036 kg m−3 (Cu). Furthermore, the heavy metal mean concentrations of TGH and VRAH present in the BA analysed samples were ranked in descending order: Ti > Zn > Fe and Ti > Fe > Zn, respectively. It is therefore recommended that BA must be properly disposed of because of the hazardous nature of heavy metals present in the analysed samples, which are able to cause environmental and public health issues.Springer NatureRepositório Institucional da Universidade Fernando PessoaDebrah, Justice KofiDinis, Maria Alzira Pimenta2023-04-14T16:17:21Z2023-04-142023-04-14T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10284/11762engAPAth: Debrah, J.
