“…Dust can contain radioactive elements due to human activities like construction, mining, and industrial procedures that release radioactive contaminants into the environment (IAEA, 2019).Dust, which is made up of microscopic airborne particles, both natural and manmade, can be found in many different places. (Ediagbonya et al,2022;. In contrast to anthropogenic sources, which include activities like mining, construction, and transportation, rock weathering, volcanic eruptions, and wind erosion are examples of natural causes of dust.…”

This research investigates the numerous facts of radioactive elements, including their origins, how they impact various ecosystems, how they affect living beings as well as inanimate objects, how they can be quantified, and how they can be cleaned up. Samples were collected from Wuye Abuja, Guzape Abuja, Ore Ondo State, Ilado Ondo State, and Irele Ondo State, which are all locations in Nigeria. Each of these locations has a unique climate as well as other environmental characteristics. Ionizing radiation-emitting substances can be found in nature as well as be produced artificially. They have raised concerns because of their potential to harm nearby materials and living organisms. Obtaining a complete picture of how radioactive elements behave around the planet is the aim of this study. To understand how radioactive materials enter the environment, research examines both natural (such as uranium and thorium) and man-made (such as nuclear fallout) sources. For Samples A, B, C, D, and E, the mean concentrations of radium (Ra-226) are 185.20, 162.53, 142.28, 97.27, and 100.70, respectively. For Samples A, B, C, D, and E, the mean concentrations of uranium (U-238) are, respectively, 83.48, 84.60, 70.17, 47.57, and 48.07. Thorium (Th-232) average concentrations for Samples A, B, C, D, and E are 33.07, 26.86, 31.53, 26.40, and 27.60, respectively. While the mean potassium (K-40) concentrations for Samples A, B, C, D, and E are, respectively, 224.47, 115.70, 127.07, 62.30, and 78.33.Except for Uranium (U-238) with 84.60 in sample B, the results showed a significant difference in sample A. The highest values of Radium (Ra-226), Thorium (Th-232), and Potassium (K-40) were 185.20, 33.07, and 224.47, respectively.

“…The soil, water, and air all contain chemicals and persistent organic contaminants that are recyclable [1][2][3][4][5][6]. Common hazardous and biological reactions they are known to cause include body weight loss, thymicatrophy, cutaneous disease, hepatic damage, teratogenicity, reproductive toxicity, immunotoxicity, and high induction potency of 3-methyl cholanthrene type hepatic microsomal enzymes [7].…”

Polychlorinated biphenyls (PCBs) adhere to soil particles and persist there for a considerable amount of time. Their near proximity might expose people by ingesting, inhalation, and skin contact, which could have neurotoxic, mutagenic, and cancerous health effects. In Okitipupa, Ondo State, Nigeria, this investigation measured the level of PCBs in soil at five different sites. A GC paired with an ECD detector was used to evaluate the sample. Concentrated H2SO4 was used to clean the extracts. According to the study's findings, the average concentration of PCB congeners at the different sites was 5.364 g/kg, with a range of 0.150 to 13.30 g/kg. Recovery rates for specific PCB congeners ranged from 87% to 100%. The number of polychlorinated biphenyls (PCBs) in the soil was higher than the 0.050 mg/kg WHO acceptable limit. TetraPCB and triPCBs have a strong positive connection. The correlation between the soil's pH and total PCBs was positive and strong (r = 3.95) while the correlation between the soil's EC and total PCBs was negative and strong (r = -0.411). The estimated daily intake (EDI) ranged from 3.0* 10-7 to 6.0* 10-7 incremental lifetime cancer risk (ICLR) ranged from 2.0* 10-6 to 4.0* 10-6. While the quotient hazard (QH) values varied from 9.0* 10-4 to 2.0* 10-3, The EDI, ICLR and QH were within USEPA tolerable risk limit
