Bayesian source apportionment and eco-probabilistic risk assessment of aliphatic and polycyclic aromatic hydrocarbons in sediments from the offshore area between the Deep Water Tano and West Cape three points blocks, Ghana.

This study investigates aliphatic and polycyclic aromatic hydrocarbons in sediments from offshore Ghana, focusing on their distribution, sources, and ecological risk. Samples were collected from 15 sites near Deep Water Tano and West Cape Three Points blocks. GC-FID and GC-MS analyses revealed higher concentrations in West Cape Three Points compared to Deep Water Tano.

Reduction in mycotoxin levels of African nutmeg () powder using a high-energy electron beam.

This study investigated the role of irradiation with a high-energy electron beam in reducing mycotoxin levels of African nutmeg powder (ANP) samples. African nutmeg was procured from a local market in Accra, Ghana, cleaned, milled, packaged and irradiated using electrons of energy 9 MeV at doses of 2, 4, 6 and 8 kGy. Un-irradiated ANP served as a control.

The effect of soil types, pH, and geographical locations on carcinogenic metal buildup in Oryza sativa cultivated in Ghana.

This study investigated the impact of soil type, pH, and geographical locations on the accumulation of arsenic (As), lead (Pb), and cadmium (Cd) in rice grains cultivated in Ghana. One hundred rice farms for the sampling of rice grains and soil were selected from two regions in Ghana-Volta and Oti. The concentrations of As, Pb, and Cd were analyzed using ICP-OES.

Deciphering groundwater pollution in the Lower Anayari Catchment: insights from using δH, δO, PMF, and APCS-MLR receptor model.

This research provides a comprehensive analysis of groundwater pollution in the Lower Anayari Catchment (LAC) through δH and δO isotopic analysis, along with positive matrix factorization (PMF) and PCS-MLR receptor models. Forty groundwater samples were collected from hand-dug wells and equipped boreholes across the LAC. Flame photometry for Na and K, complexometric titration for Ca, ion chromatography for Cl, F, NO, SO, and PO, and atomic absorption spectrometry for Mg, Fe, Pb, Cd, As, and Ni were analytical techniques/instruments employed.

Microbial food safety of lettuce produced under irrigated wastewater from Onyasia River in Ghana.

Fresh produce continues to be the main source of foodborne illness outbreaks, particularly in developing countries where water stress results in the use of surface wastewater all year round for irrigation of vegetables. The objective of the current study was to evaluate the microbial quality of lettuce irrigated with wastewater from Onyasia river. Lettuce and soil were sampled from selected vegetable farms on the Eastern gate of the Ghana Atomic Energy Commission land alongside surface wastewater from the Onyasia river, which is used as the main source for irrigation.

Occurrence, ecological risk assessment and source apportionment of pharmaceuticals, steroid hormones and xenoestrogens in the Ghanaian aquatic environments.

Elevated levels of pharmaceuticals, steroid hormones and xenoestrogens (PSHXEs) in the aquatic environment pose a serious threat to the ecological balance. The endocrine disrupting PSHXEs in aquatic systems are linked to several adverse effects like reproductive health impairment, feminization, high mortality rate, decreased biodiversity etc. This study, therefore, sought to investigate the occurrence and the ecological risks posed by some selected PSHXEs and also conduct source apportionment of the PSHXEs in the Ghanaian aquatic environments.

PAHs contamination levels in the breast milk of Ghanaian women from an e-waste recycling site and a residential area.

Breast milk samples from 128 primipararae and multiparae Ghanaian women were screened for Polycyclic Aromatic Hydrocarbons (PAHs) from 2014 and 2016. These were breast milk from women residing or working around an electronic waste recycling site and a reference area (a residential area). This research is aimed at assessing PAHs levels in human milk samples from some Ghanaian mothers, prediction of the sources of these PAHs and the probable carcinogenic and mutagenic risks to infants.

Assessment of PCBs and exposure risk to infants in breast milk of primiparae and multiparae mothers in an electronic waste hot spot and non-hot spot areas in Ghana.

The aim of the study was to assess the levels of PCBs in the breast milk of some Ghanaian women at suspected hotspot and relatively non-hotspot areas and to find out if the levels of these PCBs pose any risk to the breastfed infants. A total of 128 individual human breast milk were sampled from both primiparae and multiparae mothers. The levels of PCBs in the milk samples were compared.
