ENVIRONMENTAL IMPACT OF POLUTANTS ON SOIL AND SUBSOIL

The paper present details of analysis of soil samples which were contamined in soil, in rihizosphere areas. Surface samples were collected from a depth of about 0-15 cm. Depth samples were taken from a depth of about 20-40 cm.
Research and methods: soil samples were taken as „Technical Guidelines on procedures for investigation and assessment of soil and subsoil” issued in accordance with GD. 1408/2007 and Ord. 184/1997. The sample is soil under the influence of soil heavy traffic recreation area, near the intersection Mangalia – Saturn.
The indicators which were analysed are:lead, nickel, copper, total chromium, zinc. For each indicator, were analysed, from April to October month, the quantities (in mg/d. s), for 3 types of usage:normal, alert threshold, intervention threshold, for Mangalia - Saturn – Area and for Mangalia - Saturn – Depth.

Results: risk matrix and calculations of test solutions.
Conclusions: The trend is the accumulation Ni and Cr in all indicators have not exceeded the normal values. Indicators Cu and Zn values determined in generel ranks around the normal, with few exceptions below alert threshol..
