The capital of F.Y.R.O.M. - Skopje is the largest urban settlement in the country with the popu­lation of some 550 000. The city is situated in the north of the country about 35 km from the F.Y.R.O.M. -Yugoslav border. It has highly developed infrastructure and a large number of traffic ar­teries. The large number of streets, crossings and traffic lights along with the largenurnberof vehi­cles make the city one of the places that are most exposed to pollution. The large exposure to pollution that comes from vehicles and industrial plants ,has a negative impact on some parts of human environment (soil, plants and water).The major goal of this investigation is to determine the amount of lead and other toxic heavy metals in individual parts of the environment. The final goal of the investigation is to draw the right
conclusions that will contribute to the improvement of the human environment in the city. Sample collecting calls for specific methodology (particularly from soil and plants) arid their spe­cific preparation and appropriate analytical determination. The methodology applied included: collecting of samples from the soil; preparation of samples
for study; determination of the contents of lead and other heavy metals present and the application of the most appropriate methods of determination (ICP-MS, ICP-AES).interpretation of the results obtained.
The manner of taking samples from the soil largely affects the reliability of the results obtained. In this manner, samples can be:
-individual, if taken from one site.
-average, if made up of several individual samples (20-25).
Samples are usually taken from 0 to 20 cm in depth, only in speCific cases 40 to 40 cm in depth.
Collecting samples can be done with a pipe sampler or pedologic knife. Field samples are collected and dried in dryers at ao°c for 24 hours. The dried material is crushed, sieved and analysed.
