Water samples were collected from 17 monitoring points monthly/quarterly between 2013 and 2016 and the elemental analyses were carried out using Inductively Coupled Plasma Mass Spectrometry (ICP-MS)

This research explores the measurement of background nuclear radiation, rate of exposure and the radiological risk for the inhabitants of South-western Nigeria. The measurement was carried out using Rad*Scanner model 500VBR, which measures radiation dose in count per minute. The mean absorbed dose rate ranges between 147.26 ± 8.13 nGy h−1 and 228.20 ± 20 nGy h−1, the annual and collective annual outdoor

Oil fingerprinting is concerned with determining the chemical profile of a spilled oil to determine its origin, whether that be a vessel, well or other source. Asphaltenes are typically discarded in this process even though they are considered refractory in comparison to the volatile fraction and have the ability to provide valuable information in oil fingerprinting. A heavy fuel oil was exposed to

Widespread land clearing for agriculture activities, urbanisation, development of hotels and residential areas has rapidly altered the land use in highland areas. These scenarios have continuously degraded the quality of river water in the area and consequently increased the risk of adverse health effects. This study investigated the impact of seasonal change on river water quality and dissolved metals

Elemental composition and heavy metal speciation of the soils of Ejigbo oil depot, Lagos state, Nigeria were determined to assess the contamination status of the study area. Oil-impacted and control soils were collected from the oil depot and uncontaminated areas respectively.
