For the palynological investigation, sixty samples were thoroughly analyzed in which fairly diversified palynofloral assemblages of Gondwanic affinity were recorded. About 30 genera and 50 species of palynomorphs, belong to Glossopteridales, Coniferales, Cordaitales of gymnospermous pollen, pteridophytic spores. In the present communication, the palynoflora belongs to Glossopteridales viz. Scheuringipollentites barakarensis, S. maximus, S. tentulus, Ibisporites diplosaccus, Primuspollenites levis, P. densus and Sahnites thomasii etc. Frequency distribution pattern of the palynotaxa reveals that the assemblage is dominated by the non-striate disaccates followed by striate disaccates, monosaccates (gymnosperms) and pteridophytic spores. The diversified palynoassemblage of both non striate and striate disaccates pollen strongly signifies that the Yellandu coal belt of Godavari graben belongs to Barakar Formation of Early Permian age (Late Sakmarian-Early Artinskian). Predominance of nonstriate disaccate pollen recorded from the Yellandu sediments indicates a warm and high humid climatic condition with fluvial environment of deposition.

These taxa belong to Fabaceae, Lecythidaceae, Lythraceae, Myrtaceae and Sapindaceae families. The pollen of these arborescent plants have diversity in pollen morphological characters viz., symmetry, shape, polarity and ornamentation but significantly all the pollen taxa have syncolpate apertural partten. This study provides palynological data of the syncolpate pollen taxa, which will be useful for future palynotaxonomic studies to identify the arborescent plants of Karimnagar district.

The predominant pollen grains were those of Peltophorum pterocarpum, Ageratum conyzoides, Tridax procumbens, Prosopis iulifera, Cocos nucifera, Pithecolobium dulce, whereas the spores of fungi i.e. Alternaria sp., Ascospores, Torula sp. and Curuularia sp were observed. Several pollen grains and fungal spores, reported during present study are known to be allergenic. The investigation revealed that spider webs act as natural pollen traps, and are useful to know the incidence of allergy causing pollen during winterseason.

These charcoal particles are widely accepted to be of palaeo-wildfire produducts and this study contributes to the Lower Permian wildfire data of Indian peninsular region. During this time, a global biotic crisis was taking place and changes in the palaeofloristic composition can be observed. The samples were processed by standard palynological method, using acids like HCL, HF and HNO3, followed by alkali (KOH) treatment. In the present investigation, the microscopic charcoal particles are studied along tracheidal elements and palynomorphs related to gymnosperms were recorded and these confirmed the occurrence of palaco-wildfires in Yellandu coalfied. This contributes to the understanding of regional changes that took place during Permian period on Gondwana land. the presence of charcoal in Permian sediments associated with coal levels at different localities demonstrates that wildfires have been relatively common events in the peat-forming environments in which the coal formation took place in the Godavari graden.

Sixty samples were thoroughly analyzed from the Jawahar khani-5 and recorded 3 fossil algal species viz., Leiosphaeridia sp. belongs to Prasinophyceae, Balmeella sp. of Schizomorphitae, and Tetraporina sp. of Zygnematophyceae. These acid resistant algal microfossils along with the palynostratigraphic markers of Barakar Formation of study area show the Early Permian affinity. Marine incursion is reflected by the presence of palynomorphs such as Leiosphaeridia sp., Tetraporina sp. and Balmeela sp. Presence of these algal elements indicate the marine environment and hence the depositional Yellandu coalfield area is nearby shallow marine environment.

These spider webs, the natural pollen traps, were processed by using Erdtman's acetolysis technique (1960) and recovered pollen taxa viz. Xanthium strumarium and Ziziphus mauritiana. The quantitative and qualitative analysis of palynological data reveals the dominance of arboresent plants. Hence the spider webs are functioning as air monitors which are useful for aeropalynological survey by trapped dispersed pollen in the spider webs of Rangaraopet village in Karimnagar district.

An aerobiological investigation was carried out at Pakhal wildlife Sanctuary, Warangal district, Telangana state to
know the incidence and effects of aero biota by using palynological data collected from the spider webs during
winter season. Four spider web samples were collected from Pakhal wildlife Sanctuary and processed by using
Erdtman’s acetolysis technique and recorded 30 pollen grains along with fungal spores belong to 18 families. In
this study the following allergenic pollen viz., Parthenium hysterophorus, Ageratum conyzoides, Peltophorum
pterocarpum, Prosopis julifera, Eucalyptus globulus, Xanthium strumarium, Abutilon indicum, Syzygium cumini,
Azadirachta indica and Poaceae pollen and some fungal spore like Alternaria sp., Curvularia sp., Torula sp. were
also recorded. The dominance of fungal spores is due to the unhygienic and interference of anthropogenic
activities around Pakhal Lake. These are the indications of humid climatic conditions. The present study is useful
not only to know the incidence of pollen or aeroallergens and also know the effects of allergenic diseases like
allergy, asthma and hay fever or seasonal rhinitis to the human beings and also the wild life in Pakhal wildlife
Sanctuary.

Total sixty samples were analyzed from the Jawahar khani-5 for the palynological investigation thoroughly. About one taxon protist (thecamoebian) Arcella artocrea belongs to the family Arcellidae was recorded. During palynological investigation, the dominance of non striate bisaccates pollen grains followed by striate bisaccates and the other stratigraphically significant palynomorphs, viz., Scheuringipollentites, Faunipollenites, Rhizomospora, Ibisporites, Striatites and Microbaculispora etc. in the sediments shows Barakar Formation of Early Permian affinity. The thecamoebian was recorded along with the palynostratigraphic markers of Permian sediments of the study area also shows the Early Permian affinity. Presence of these microfossils indicates the freshwater habitat and cooler climatic conditions prevailed at the time of deposition in the study area.

Some airborne bioparticles cause allergenic reactions. An allergy caused by pollen grains is called pollinosis or allergenic rhinitis. Allergic reactions begin in your immune system, when a harmless substance such as pollen, fungal spores, dust or mold is encountered by a person who is allergic to that substance, the immune system may overreact. It may produce antibodies that attack the allergen. Symptoms of pollen allergy include sneezing, itching or runny nose, nasal congestion, redness, itching and watery eyes. Substances that cause allergies, including pollen, can trigger asthma. Airborne pollen such as pollen from trees, grasses and weeds cause allergenic reactions like Conjunctivitis and nasal mucosa, when tissues are allergic to cell-bound immunoglobulin E (IgE), release tissues that mediate histamine and annoying allergic symptoms. Our immune system produces substances known as antibodies. When people come into contact with the allergen, their immune system's reaction can inflame your skin, sinuses, airways or digestive system. Pollen exposure weakens the immunity against certain seasonal respiratory viruses by diminishing the antiviral interferon response. Coexposure to airborne pollen enhances susceptibility to respiratory viral infections, regardless of the allergy status and the effect could be stronger for those with allergies. Aerobiology will be useful for finding solutions to mitigate the environmental pollution of our country. Especially from the clinical point of view, it is important to know the details about the pollen season and pollen load in the atmosphere. Monitoring of airborne pollen and spores is at most important. So, aerobiology has a very important role to play concerning human health allergies and we hope to bring about a solution to monitor and control pollen and spore allergy in urban areas.
