Biological particles, industrial and diesel particles playa fundamental role in urban pollution levels often altering the health of thepopulation. Studies conducted in the atmosphere of San Miguel de Tucumán city during9 years with a volumetric sampler located 20 m of high are presented. Using an opticalmicroscope 83 pollen types were identified from which 4 herbaceous types(Urticaceae, Asteraceae, Poaceae and Amaranthaceae) and 10 arboreal types (Broussonetia, Morus, Fraxinus, Quercus,Celtis, Alnus, Juglans, Solanaceae, Anadenantheraand Mirtaceae) have contributed with the highest concentration recordedthroughout all the period and most of them have allergenic properties. Also, there have beenidentified other bioparticles as spores of fungi (Alternaria, Fusarium, Spegazzinia) and spores ofPteridophytes. During the of May to October the atmospheric cloud is break in byresidues of plant tissue derived from industrial activity of the harvest of sugarcaneand / or from the burning of sugar cane plantations, these elements jointlywith the emissions of diesel particles and inorganic material represent adetermining factor in causing various diseases in the population such as eyeirritation and conjunctival membranes disorders; respiratory irritation andaggravation of bronchopulmonary diseases. At the same time of year, little orno rainfall, low relative humidity, increase temperature and wind speed arerecorded, favoring suspension and permanency of particles in the air.Continuous aerobiológical studies of these bioparticles contribute tounderstanding of its dynamics as well as to take preventive steps to ahealthier life.
