“…This study suggested a climate change experience resulting in a longer and/or highly seasonal dry period in southern Nigeria. 13 Adeonipekun 13 further confirmed the inferences made by Adeonipekun and John 24 Similarly, Orijemie and Israel 30 sampled the air filters of 20 vehicles that travelled to several parts of Nigeria with the aim of using the associated palynomorphs to reconstruct their routes. Reconstruction of the routes was successful in 75% of vehicles.…”

“…In Nigeria, aeropalynology research has included climate change as part of its goal. 13,24,30 Adeonipekun and John 24 studied an unusual dust that swept across Nigeria in March 2010; they found that the dust was from a late Harmattan period. This late occurrence of the Harmattan dust indicated a delayed inter-tropical continental zone whose position should have moved further north but maintained it until the month of March 2010.…”

Background: Aeropalynology is a branch of palynology that studies the content of atmospheric pollen grains and spores. The amount, concentration, and distribution of these aerospora are influenced by the seasonal flowering of parent plants and variations in climatic conditions as well as local and regional variabilities. Atmospheric pollen grains and spores are diverse and have been identified as major biological particles that trigger immune cells to release inflammatory chemical mediators, inducing respiratory-linked and allergic conditions, such as polli-nosis, among susceptible individuals. Objective: The burden of these allergic conditions on patients, families, healthcare systems, and governments has risen globally, thereby affecting developing countries, including Nigeria, wherein the financial and infrastructural institutions are not effective enough to mitigate these challenges. Avoidance of allergenic aerospora is an effective mode of addressing pollinosis with its associated conditions. However, there is a need to ascertain the atmospheric quantity, diversity, and pattern of occurrence of allergenic pollen/spores. Results: In this paper, we reviewed published articles on aeropalynology in Nigeria with atten-tion to the design and duration of the study and the used equipment. We further investigated whether identification and quantification of allergy-causing palynomorphs was part of published articles’ foci. Conclusion: The availability of such data/information is crucial for reducing epidemiological uncertainties, enhancing the diagnosis of allergic conditions, and securing a robust set of mitigation strategies and/or effective treatment of these conditions in Nigeria.

“…As a result, during prosecutions, almost all confessional statements are challenged on the basis of police coercion. A significant challenge facing law enforcement agencies has been identifying vehicles associated with crime scenes and suspects (Orijemie and Israel, 2019;Adekanmbi et al, 2021). To address the challenge, there is a need to generate data sets of ecological marker species that will be used to associate vehicles with specific routes.…”

“…Car air filters (CAFs) are installed in ventilation systems and motor engines to prevent particulate matter from tampering with engine mechanics. They have also been used as low-cost "active-passive" air sampling media for hydrophobic organic compounds and palynomorphs for forensic palynological studies (Katsoyiannis et al, 2012;Cai et al, 2014;More et al, 2013;Orijemie and Israel, 2019). The parts of the car, particularly the air filters, hold a large amount of aerosol, which contains pollen grains, spores, fungi spores, insects, and other constituents (More et al, 2013).…”

This study focuses on the significance of airborne pollen grains and spores as markers for tracking vehicles along specific routes. Using standard methods, the research examined monthly pollen distribution and its correlation with meteorological data. Dust and soot samples were collected monthly from the car air filters of commercial vehicles traveling on the Ife-Ondo road and subjected to palynological analysis for a period of 24 months. The findings revealed a total of 393 pollen grains and 131 spores, representing 40 pollen and 22 spore types from 27 and 17 families, respectively. Notable markers among these include Hagenia abyssinica, Podocarpus milanjianus, Theobroma cacao, Cannabis sativa, and Myrianthus arboreus, among others. These markers serve as crucial identifiers for vehicle-related investigations. The study revealed a statistically significant positive correlation between monthly total airborne pollen concentrations and relative humidity, rainfall, and wind speed. In a practical context, the study has created a valuable dataset and monthly atlas of pollen and spore types. This resource can be instrumental for security agencies in their efforts to investigate vehicle-related crimes and monitor vehicular movements along the Ife-Ondo road.
