“…Accordingly, everyone ran for cover when the rain began to wash out the dust as predicted by NIMET. Sample of dust was collected and analyzed by Adeonipekun and John [9]. The Palynological result of the study confirmed that the dust was of Saharan origin.…”

Pathogens in the dust suspended in the atmosphere are known to cause sickness such as cough and throat problems. An unusual dust episode occurred over the coast of West Africa Gulf of Guinea between March 20 th and March 29 th in 2010. The occurrence was seen as unusual because of the time of occurrence. The cause of the dust outbreak was investigated using wind data at various pressure levels from ECMWF Re-Analysis (ERA) interim dataset. Data of horizontal visibility from two near the coast locations were used to calculate the dust load during the period. Results show that dust load during the episode was about 15 × 10 5 kg and 3 × 10 5 kg per square kilometer over Akure and Lagos respectively. Also that winds at the African Easterly Jet level (core at 750 hPa) suddenly changed from westerly to easterly thereby causing the reversal of Planetary Boundary Layer (PBL) winds. Since the dusts are embedded in within the PBL, wind reversal brought load of dust to the south coast of Gulf of Guinea at very unusual time of the year. The study concludes that watching and monitoring winds at the AEJ level could help in predicting dust pollution outbreak over West Africa.

“…As stated earlier, the biological contents of the March 2010 hazy dust in Nigeria deserve verification due to the attendant panic it brought to the public (Adeonipekun and John, 2011). Allergenic pollen produce certain chemicals, most important are histamines.…”

Palynology has become a well-established research tool leading to enormous breakthroughs in the world of science. As a result, Palynology has integrated perfectly into multidisciplinary programmes, such as Melissopalynology, Aeropalynology, Forensic palynology, Agricultural palynology, Fossil palynology, Morphorgraphic palynology (pollen morphology, pollen productivity), Latropalynology, Palaeopalynology including many other areas. Through these multidisciplinary programmes, Palynology has found various applications in Archaeology, Geology, Criminology (Forensic science), Allergology in medicine, Plant taxonomy, Stratigraphy, Paleoecology, Paleobotany and Petroleum industry. The term palynomorph includes both pollen of spermatophytes, spores of fungi, ferns, and bryophytes, as well as other organic-walled microfossils such as dinoflagellates and acritarchs. Pollen grains can be studied for comparative morphological data, clues to unexpected aspects relating to breeding systems, pollination biology and hybridization. This can bring about a better understanding of the whole biology of the group under investigation. Forensic palynology deals with the use of pollen and spores in disproving or proving relationships between people, crime scenes and objects so as to resolve civil or criminal cases. In recent petroleum researches, palynology has become an important tool in resolving many age and facies correlation problems. Palynologists are evolutionarily oriented botanists working ultra-structurally, especially those routinely using Transmission Electron Microscopy (TEM). They are perfectly trained, highly experienced scientists who regularly bring solutions to socioeconomic problems. It is in view of this that we present an overview of the various contributions and the significance of palynology, and how it could be further harnessed in bringing about socioeconomic development in Nigeria.

“…This, together with the abundant diatom frustules recorded, further supports a Saharan desert source for the strange dust. Apart from the published work of Adekanmbi and Ogundipe (2010) in the southwest Nigeria and most recently Adeonipekun and John (2011), there is no other aeropalynological work in this area (Ilorin) to serve as a basis for aeropalynological study. Even the Adekanmbi and Ogundipe (2010) work only identified most of the recovered palynomorphs mainly to family level thus not creating the needed basic data for comparative pollen analysis.…”

“…In March 2010, a strange harmattan dust covered the whole of Nigeria and raised issues bordering on changing weather conditions and its consequence on public health. Adeonipekun and John (2011) investigated this cream coloured dust and found out that pollen grains of Guinea/Sudan savanna vegetation species were dominant. This, together with the abundant diatom frustules recorded, further supports a Saharan desert source for the strange dust.…”

The work of Adeonipekun and John (2011) also was carried out on the dust deposited on a car bonnet over a month. The sample used was not directly collected from the air with an aerofloral sampler.…”

ABSTRACT:Hay fever allergy could either be from pollen or fungi spores. Using the Hirst model of pollen trap, pollen buckets were constructed; with pollen trap solutions inside them, they were placed in specific locations in the University of Ilorin for four months (December 2012/January 2013 to March/April 2013). Using acetolysis reaction, pollens and spores were recovered from the trap solution and were analyzed and identified in the microscope. Pollen/spore were counted and compared with meteorological parameters i.e. rainfall, sunshine, wind speed, humidity, and temperature. It was observed that pollen/spore concentrations were influenced by these meteorological factors. Hence there is need for us to always determine the amount of these pollen/spore concentrations all year round as it will help to predict the vegetation of a given area as well as helping hay fever sufferers manage their allergies effectively. ©JASEM http://dx.doi.org/10.4314/jasem.v19i1.7
