Abuja Municipal Area Council (AMAC) is experiencing rapid urban expansion, which expected to impact land surface temperatures (LST). This paper evaluates the trends in soil adjusted vegetation index (SAVI), normalize difference buildup (NDBI), and temperature (LST) between 1987 2023 AMAC using Landsat 4 Thematic Mapper 8 Operational Land Imager/Thermal Infrared Sensor imagery, respectively. Results show that 1987, SAVI ranged from -0.126 0.477, NDBI -0.186 0.678, LST 27.18 46.4 oC. In 2023,...

Abstract The concentrations of 16 pesticides residues (alpha BHC, gamma BHC (lindane), beta Heptachlor, Aldrin, Heptachlor Epoxide, Endosulfan I, Dieldrin, Endrin, II, 4, 4 DDT, Aldehyde, sulfate, Atrazine, Phosphomethylglycine and Carbofuran) in two fish species ( Tilapia zilli Clarias gariepinus ) from selected rivers (Illushi, Owan Ogbesse) Edo State, Nigeria was investigated the associated human health risks consumption contaminated fishes also determined. Fish were collected for a...

Abstract There is an intrinsic link between polycyclic aromatic hydrocarbons (PAHs) accumulated in soils and increased health risk to humans after exposure contaminated soil via ingestion, inhalation of particulates carrying PAHs, direct contact with polluted soils. However, the assessment PAH contamination most developing countries fails consider assessment. Therefore, a comprehensive study was conducted determine concentration, source, toxicity, human risks 16 PAHs urban area Warri, Delta...

The decrease in air quality has been a major concern the world for decades, and it continued to worsen with toxic gases accumulating at exponential rates. atmosphere heavily polluted as result of anthropogenic activities, these activities were greatly reduced during COVID-19 pandemic when lockdown policy was imposed. study area, Lagos, is state Nigeria highest population count, making most susceptible spread coronavirus and, such, having strictest regulations. This seeks evaluate effects on...

Mushroom species are valued in gourmet traditions around the world for their unique taste, aroma, nutritional value and medicinal potentials. The bioactive profiling of P. tuberregium mushroom was evaluated to determine it therapeutic effect on Wistar albino rats exposed arsenic (As) chromium (Cr) toxicity. Proximate analysis showed high composition carbohydrate (80.24) followed by moisture (21.16), protein (11.46), ash (3.03) fibre (0.25) content. Phytochemical revealed presence polyphenols...

This study was aimed at investigating the relationship of trace metals with prevalence bacteria and fungi in polluted farmland Egbema Kingdom, Delta state. may contribute to knowledge on influence microorganism arability agricultural soil from an ecotoxicological viewpoint. Soil samples were analyzed for physico-chemical parameters using atomic absorption spectrophotometer (Buck Scientific, 210VGP). The also screened isolates. Trace (Fe, Zn, Cd, Ni Cu) determined soils kingdom below WHO...

Reported declines in amphibian faunal diversity Nigeria Niger Delta due to chemical contamination and habitat alteration provided the impetus for this study. The potential anthropogenic metal affect survival was examined by evaluation of acute toxicity heavy metals cadmium (Cd) lead (Pb) early larval stages B. maculatus P.bibroni at varying post-hatch maturation (3 days, 1, 2, 3 4 weeks) under laboratory conditions. were exposed nominal Cd Pb concentrations 0.10, 0.15, 0.20, 0.25 0.50 &mu;g...

Five heavy metals (Cu, Pb, Ni, Cd, Fe) were accessed in surface sediments from Ikpoba River Benin City, South of Nigeria; an area impacted by soil erosion and the Water Storm project. The analysed using atomic absorption spectrometer. mean concentrations 0.543 mg/kg (Pb), 1.289 (Ni), 0.001 (Cd), 18.90143 (Cu) 1022 (Fe) respectively.
