Bacterial deposition method was applied over hard to detect microbial community transmission of the germs with air by droplets and dust combine in some poultry farms chicken broiler and hen layer after determining the level of the microbial load in the barns. - Observed in this study that most of the farms studied the conditions did not apply the proper care and education in terms of ventilation and servicewhich impact positively on the growth and reproduction of bacteria and increased bacterial load and fit the level of contamination parcels with high temperatures and humidity for some bacteria, including Staphylococcus and Streptococcus. - As results showed in the classification of isolates according to the api that tests for Staphylococcus aureus bacteria (Staphylococcus xylosus Staphylococcus aureus), Escherichiacoli and (Homophilesparagallinarum) Also transmission of infection and diagnosis of injury satisfactory bacterial isolates from compatible ambient air in poultry flocks in adjacent pens in farms.
Meteorological elements affect the dynamics of air pollutants, where these elements can play an important role in dispersing and transferring air pollutants as well as to photochemical reactions of secondary air pollutants. This study was conduct ed to analyze the effect of several meteorological variables on the concentrations of some air pollutants (Co, NO2, SO2, O3, PM10) at two sites in Damascus city, by using the Pearson correlation coefficient.
The present research was conducted to study the resistance of Acasia tree which were near to Banias- Jableh freeway. This study was performed by study the stomata and its distribution on the upper and down leaf surfaces. Also, a concentration of c hlorophyll and a severity of photosynthesis, then compared the results between the polluted region with the control one. Results showed that a number of stomata decreased in polluted region compared to the control one, where this reduction play a role in reduce the injury resulting from gas air pollutants, and this reflexes on the severity of photosynthesis and the chlorophyll.
