Seasonal influence on suitability of masquerade tree as a bioindicator of vehicular pollution along University of Ilorin Road, Nigeria Mojeed Bello, Nasiru Abdus-Salam, Lateef Ibrahim, Taoheed Bello, Abubakar Aremu, et al. Journal of the Serbian Chemical Society, 2026 This study focused on the seasonal impacts on the suitability of masquerade (Polyalthia longifolia) as a bioindicator of vehicular pollutants. Some leaves of the tree were plucked along the roadside and from a control site with no vehicular emissions. Biochemical parameters, including pH, ascorbic acid content, relative water content, total chlorophyll and air pollution tolerance index (APTI), were determined in both dry and wet seasons using standard methods. Potentially toxic elements (PTEs) commonly associated with automobile pollutants (Pb, Zn, Cr, Mn, Fe and Cu) were analyzed using atomic absorption spectroscopy, after acid digestion. The concentrations of PTEs were slightly higher in leaves from roadside masquerade tree than in those from the control site, except for Cr and Cu at some sampling points during the wet season. The biochemical properties in the roadside samples indicated the presence of pollutants compared to the control site in both seasons. APTI of the roadside samples showed higher sensitivity (mean value = 10.30) in the dry season, indicating a gradual loss in tolerance to pollution; however, a slight increase (mean value = 11.23) in tolerance was observed in the wet season. The masquerade tree demonstrated its sensitivity to vehicular pollution in both seasons. It is more sensitive in the dry season but tends to tolerate pollutants in the wet season by increasing APTI through improved defense mechanisms.
Spatio-temporal monitoring of potentially toxic elements in Lagos harbour water and its health risk implications Kazeem A. Basheeru, Folahan A. Adekola, Nasir Abdus-Salam, Hussein K. Okoro SN Applied Sciences, 2022 Continuous discharge of industrial and domestic inputs from various processes into the Lagos lagoon has significantly affected the quality of the aquatic environment, as a result of potentially toxic elements (PTEs) being released into the harbour during anthropogenic activities. This study involved monitoring the concentration and distribution of heavy metals in Lagos harbour during the dry and wet seasons. The PTEs can pose a serious ecological threat to the marine environment as well as human beings when the level of priority metals like cadmium, lead, and chromium is beyond World Health Organization (WHO) limits of 0.003, 0.05, and 0.1 mg/L, respectively. The shipping activities within the harbour play a significant role in the generation of these toxic metals. The diverse nature of these metals coexisting with their oxidation states in aquatic environments and their bioaccumulation influences the toxicity of PTEs towards the living organism. The quantification of these metals with highly selective and accurate instrumentation is imperative. Ion-selective exchangers and other functionalized composite nanomaterial are critical for harbour water remediation because of the high risk that could be associated with prolonged exposure to these toxic elements especially when the carcinogenic risk value is greater than 1 × 10−6 mg/kg/day.
