CONTENT OF WATER SOLUBLE AND INTERCNANGEABLE FORM OF LEAD IN THE ROADWAY DUST LOANG THE MAIN ROAD M-17 THROUGN THE CITY OF MOSTAR

Abstract

One of the most significant contributors to the heavy metal concentration growth, especially lead metal concentration growth in the soil is traffic. The main objective of the study was to determine the lead content and its concentration in water of soluble and interchangeable forms of lead on the M-17 road in Mostar has been done. Observing this road, five different locations had been chosen for exploring the defined task. Road dust samples were taken in the first cycle, fall 2018. The specified metal is identified according to EU standards. The AAS-flame method was used to determine total lead level and AAS-plow technique was used to determine soluble and exchangeable lead forms. According to the obtained results, the following conclusion. The results of the research show large oscillations of lead concentration on different locations. The highest concentration was found at location 5: Bišće field 498.33 mg / kg and lowest at location 3 Brankovac at 6.12 mg / kg.
