EFFECT OF BIOLOGICAL POLLUTION ON HUMAN HEALTH INNORTH EAST ALGERIA ”CASE OF SERAIDI-ANNABA REGION”Imene Layachi and Mohamed BenslamaAbstract The purpose of this study is twofold first, to identify the pollen that most likely can induce allergic symptomssecond, a review of epidemiological records was undertaken from 2013 to 2017 with the aim of determiningthe prevalence of allergy in the Seraidi region âbouzizi-djnen el beyâ in the Annaba Algeria region. Thelinking between the flowering schedule of the characteristic species of the region (Seraidi) and the results ofthe analysis has made it possible to identify the species likely to be at the origin of the recorded manifestationsof allergy. These are the pollens of certain trees (the oak which occupies the first position, Erica, Pine, Olivetree), the pollens of certain spontaneous herbaceous plants (of the family Compositae, Urticaceae (Parietal)),and pollen from certain grasses (of the family Poaceae (Fecal)). The results of the epidemiological surveyscarried out showed that the average allergy due to pollen was 198 in May for conjunctivitis and 100 in Aprilfor rhinitis and asthma. Overall, the maximum symptom frequency values recorded in March-April, Mayand August-November correspond to the maximum flowering of characteristic species. Seasonal variationsin symptoms reveal the probable role of pollens in their induction. |
