Source identification and health risk assessments of polycyclic aromatic hydrocarbons in settled dusts from different population density areas of Ilorin, Nigeria

Polycyclic aromatic hydrocarbons in dust from rural communities around gas flaring points in the Niger Delta of Nigeria: an exploration of spatial patterns, sources and possible risk

“…Despite the differences in the analytical approach, number of PAHs analyzed, and climatic conditions, such a comparison provides information on global concentration trends. The PAH concentrations in the indoor dust from these areas were higher than those reported for indoor dust from rural, semi-urban and urban areas in Nigeria 28,30,33,34 and other regions, 22,24,27,45 but were comparable to those found for indoor dust from Warri, Nigeria 30 and Changchun, China. 22 The PAH concentrations in the outdoor dust from these rural communities were higher than those previously reported for similar matrices from the Niger Delta and other parts of Nigeria 6,31,32,34–36 and some cities with diverse anthropogenic pressures in other regions, 20,23,25,26,47–49 but were lower than those of outdoor dust from Ulsan, Korea.…”

“…[15][16][17][18][19][20][21][22][23][24][25][26][27] In Nigeria, like other regions, most of the studies were focused on urban areas with high vehicular emissions, and intense commercial and industrial activities. 6,[28][29][30][31][32][33][34][35][36] Most considered outdoor or indoor dust and only a few explored their relationship.…”

Consequence modeling of liquefied petroleum gas accidental release from retail outlets in an African city residential environment

“…The gas plant locations were systematically selected in three different areas in the Ilorin metropolis, representing high, moderate, and low densely populated areas based on the population density classifications described in Adeniran et al 23 while a fourth location was selected due to its location within the proximity of the sales of other petroleum products. Table 1 lists the characteristics of the selected locations.…”

Polycyclic Aromatic Hydrocarbons (PAHs) in Urban Park Dusts from Lagos, Nigeria: Pollution levels, Sources and Exposure Implications.

“…PAHs emission are emitted during combustion of lubricating oil (Rajeev et al, 2023). Estimates of BaA/Chry are employed as markers to nd out distance of possible PAHs origins (Adeniran et al, 2021;Yusuf et al, 2022). High value of BaA/Chry (greater than 1) suggested local PAHs sources.…”
