“…The estimated AEDR control value is well within the permissible limit, while that of the gold mines are above the permissible limit [14]. A comparison between the average dose rate and AEDR estimated in this study and those presented in related literature [15,30,31,33] shows that radiation risk is not only signi cantly higher at the gold mines but are also above the global allowed dose and exposure limits.…”

“…An internal hazard index ranging from 0.74 to 0.97 Bqkg − 1 , with an average value of 0.85 Bqkg − 1 was estimated for the gold mining locations, while a value of 0.24 Bqkg − 1 was estimated for the control locations. For all the locations considered, the internal and external hazard indices are less than the permissible value of unity [15].…”

The environmental and health implications of artisanal gold mining activities in mining sites across Nigeria have rekindled research interests. This study aims to assess the scalability of Naturally Occurring Radioactive Materials in gold mining sites in Iperindo, Nigeria. Soil samples were collected from three different mining sites and control locations, and analyzed for natural radionuclides, mainly 238U, 232Th, and 40K using gamma spectrometry having Sodium Iodide detector. The average activity concentration values of 61.55 ± 3.71, 72.65 ± 4.45, 1134.99 ± 38.12 Bqkg− 1 obtained from within the mining sites for 238U, 232Th, and 40K, respectively were above the world permissible values of 33.0 Bqkg− 1 for 238U, 45.0 Bqkg− 1 for 232Th, and 420.0 Bqkg− 1 for 40K. The average activity concentration value of 15.26 ± 3.19, 21.46 ± 4.27, 381.04 ± 23.36 Bqkg− 1 estimated for 238U, 232Th, and 40K, respectively, for the control location were, however, lower than the global permissible values. The study also evaluated other radiological parameters, such as radium equivalent, dose rate, annual effective dose rate, internal and external hazard indices, alpha and gamma indices, etc. The obtained values were 252.83 Bqkg− 1, 119.98 nGyh− 1, 147.15 mSvy− 1, 0.85 Bqkg− 1, 0.68 Bqkg− 1, 0.31 Bqkg− 1, and 1.89 Bqkg− 1 respectively. With the exception of radium equivalent, external and internal hazard risks, and alpha index, which were significantly lower than the recommended threshold, all the other radiological parameters were higher than recommended global limits.

“…A hallmark of technology is in industrial emission, transportation such as roads, aviation, radiation from telecommunication, and military armaments activates climate change imprint. Air pollution occasioned by dust particles, vehicular emission, soot, nitrates, NH 3 and nitrogenous gaseous oxides (NOx), oxides of sulfur, aerosols, CH 3 , PM2.5, and PM10 activate biomarkers (ceruloplasmin, orosomucoid, C3, and alpha-1-antitrypsin), which may be a pointer to high risk at moderate exposure levels that significantly and positively elevate the risk of cardiovascular disease via chronic systemic inflammation [4]. The aforementioned effect also exacerbates and promotes progression of atherosclerosis and ups cardiovascular events, including regularity of noncommunicable respiratory diseases (NCRDs) with asthma, chronic bronchitis, obstructive respiratory disease, and allergic rhinitis [5,6].…”

“…Natural and anthropogenic processes can introduce heavy metals and polycyclic aromatic hydrocarbons (PAHs) into the water environment. The contribution of natural activities such as rock weathering, wildfires, and volcanic eruption [1] [2] to pollutants pollution are insignificant in comparison to anthropogenic sources. Some PAHs and heavy metals are byproducts of anthropogenic activities such as incomplete combustion of some natural materials, urban runoff, wastewater discharge from households and industries, oil spillage, and vehicle and industrial exhaust emissions [3][4][5][6].…”

Polycyclic aromatic hydrocarbons (PAHs) and heavy metals (HMs) are predominant pollutants linked with anthropogenic activities across a host of environmental mediums. The level of pollution, ecological and health risk were assessed in surface water from Ekulu in Enugu metropolis, Nigeria for 17 PAHs and selected HMs (As, Cd, Cr, Cu, Pb, Ni, Zn) components. PAHs and HMs were determined using a gas chromatography-flame ionization detector (GC-FID) and atomic adsorption spectrophotometer (AAS). The total PAHs in station A (3.17mg/l), B (1.51mg/l), and C (1.83mg/l) were due to high molecular weight (HMW) PAHs than low molecular weight (HMW) PAHs. HMs contents were within USEPA and WHO minimum contamination levels (MCL) except Cr and Pb. The molecular diagnostics of PAHs showed that incomplete combustion of carbonaceous compounds was dominant, while petrogenic was insignificant across all samples. The ecological indices of PAHs and HMs varied from medium to high pollution due to anthropogenic activities that pose a threat to the ecosystem. The non-carcinogenic models showed that hazard index (HI) ranged from PAHs (0.027 – 0.083) and HMs (0.0067 – 0.087) which is less than unity implying no adverse health issues. The lifetime cancer risk (LCR) for PAHs (4.21×10–4 – 9.61×10–4) and HMs (1.72×10–5 – 3.98×10–5) suggested significant cancer risk is possible over some time for a population of 1 in 10,000 and 100,000 for both PAHs and HMs exposure for 70 years. Therefore, there is an urgent need for proper pollution control and mitigation plan to preserve both age groups from being continuously exposed to anthropogenic activities in the Ekulu River and further study should be carried out to monitor the available toxicants.
