摘要
This study investigated the effect of traffic pollutants of roadside on soil microbiological activities in Turkey's south-eastern border. The soil samples were taken from different crossroad of Sanhurfa-Diyarbakir, Sanhurfa-Gaziantep, Sanhurfa-Mardin and Sanhurfa-Akcakale where traffic is intensive. Soil samples were taken from different distances from the roadside, i.e., 1, 10, 50, 100, 150 and 250 m. Microbial respiration, catalase and urease enzyme activities, concentration of Cd and Pb, numbers of total bacteria, fungi and actinomycetes were evaluated in soil samples. According to the results of the study, exhaust gaseous causes a damage on the soil biological activities. The farther down the road, the numbers of bacteria, fungi and actinomycetes, microbial respiration, catalase and urease enzyme activities have increased. The 250 m away from the road; cadmium and lead levels and tested soil microbiological activity were increased.
