Abstract EN

This research aims to estimate falling dust quantity in the main transportation garages in Hilla city and lead concentration in this dust that result from vehicles exhausts, as well as compare the results with standards limits.

As it known that the largest two garages in Hilla city are the union garage that lying on street 60, which assigned for transportation in and outside the governorate, and the second garage is Bab AL-Hussein garage that lying at Bab AL-Hussein area in Babylon city, this garage is assigned for transportation inside the governorate.

In this study six studying sites were chosen for each garage (one in entrance, and another in the exit, while the other four sites were distributed inside the garage) for monitoring and measurement, this study was done in year (2005)(during April, June, July, and September).

The results showed that falling dust quantities have wide range variety during studying period, where it wobbled in the union garage between (46.75–132.98 g / m2), and between (55.55-112.23 g/m2) in Bab AL-Hussein garage, where falling dust quantities were variety among all of studying period and did not follow unified pattern, and the same thing was for lead concentration in the falling dust where it wobbled between (42.8-230.0 mg / kg) in the union garage and between (48.85-200.22) mg / kg in Bab AL-Hussein garage.
