“…Previous studies conducted in Nigeria have similarly employed the use of gravitational and non-volumetric samplers for the trapping of airborne pollen and spores (Njokuocha, 2006;Adekanmbi and Ogundipe, 2010;Essien and Aina, 2014;Adeniyi et al, 2014;Ezike et al, 2016;Ajikah et al, 2017;Adekanmbi et al, 2017;Alebiosu et al, 2017). Higher monthly pollen concentrations were observed from October to March and this is similar to Njokuocha (2006) who reported more pollen load from September to January in Nsukka, South-Eastern, Nigeria.…”

“…In Nigeria, some aeropalynological work have been recently conducted in various parts of the country and these include investigating dominant pollen and fern spore types (Adekanmbi and Ogundipe, 2010;Adeonipekun, 2012;Abdulrahman et al, 2015;Ajikah et al, 2015Ajikah et al, , 2017Adekanmbi et al, 2017), examining correlations between pollen data and meteorological parameters (Ezike et al, 2016;Ajikah et al, 2017;Alebiosu et al, 2017); relationships between airborne pollen load and medical data (Adeniyi et al, 2014); inferences on their health risk periods (Adeniyi et al, 2014;Ezike et al, 2016;Alebiosu et al, 2017). Essien and Aina (2014) quoted Singh and Rawat (2000), stating that most pollen grains found as allergens are wind-pollinated, characteristic of a light-weight and may be dispersed to considerable distances.…”

The incidence of airborne pollen occurring as aeroallergens of varied levels at different periods of the year has generated some public health concern globally. The present study was conducted in order to examine the monthly depositional rate of airborne pollen and fern spores, as well as the impact of meteorological parameters and local plants on pollen distribution at two study sites in Kaduna and Sokoto States of North Western Nigeria. The study spanned a period of one year, during which a modified Tauber pollen sampler was employed in the collection of atmospheric pollen and fern spores; local plants were also enumerated. Residual solution was collected monthly, subjected to acetolysis and the treated residues were viewed for microscopic studies. The results reveal monthly distribution of airborne pollen and fern spore types at the study sites during the sampling period. Dominant pollen types in Kaduna State were those of Alchornea laxiflora, Pinus caribaea, Terminalia sp., Sapotaceae and Poaceae family. Pollen of Syzygium guineense, Alchornea sp., Sapotaceae and Poaceae dominated in Sokoto State. Spores of Pteris sp., Nephrolepis sp. and a trilete fern were also recovered at both locations. Some local plants in the immediate vegetation contributed to the aeroflora of these locations. No significant correlation was recorded between monthly total pollen concentrations and mean monthly meteorological parameters of the locations. It is imperative to investigate the allergenicity of these dominant pollen types, so as to aid pollen hypersensitive individuals in adopting appropriate prophylactic measures.

“…Therefore, vegetation is a major contributor to the array of pollen types recovered in the atmosphere of any location. 12,13,28 Owing to its variable geographic and climatic attributes, Nigeria has a rich plant diversity, in which almost 7895 plant species have been documented. 31 Basically, the Nigerian vegetation is controlled by climate, with special reference to the mean annual rainfall and extent of dryness in a season, suitably determined by minimum relative humidity and the period of no rainfall.…”

“…The first goal is significant because pollinosis has an "annual periodicity, with symptoms usually occurring at the same time of the year, during pollination." 55 Pollen data collected from different localities from a few months to 1 year in Nigeria, 12,13,20,21,24,[26][27][28][49][50][51][52]56 suggest that some pollen and/or spore types, based on their abundance or otherwise, could be responsible for allergenic reactions among patients of hay fever. For instance, it has been reported that Poaceae grains have a high possibility of stimulating pollinosis reaction in patients, 26 but neither this has been tested nor there are any proofs of such relationships in Nigeria.…”

“…Instances include Elaeis guineensis and some other members of the same family Arecaceae, which produce morphologically dissimilar monosulcate pollen; 35 members of different plant families of Cucurbitaceae and Rutaceae also produce morphologically similar colporate and prolate pollen types. 36,37 More so, setbacks in allergenicity studies of potential pollen allergens in Nigeria include (i) inadequate understanding of phenological shifts among plant species 28 during collection of pollen samples; (ii) difficulty in accessing human subjects; and (iii) its accompanying complexities of ethical issues. Adekanmbi et al 27 cited the work of Conejero et al, 38 and stated that an important limitation in their study of allergenicity was the subcutaneous route of Mus musculus sensitization.…”

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.
