TRANSPORT OF DANGEROUS GOODS AND RISK MANAGEMENT 45In Table 2 there is an example <strong>of</strong> the classification <strong>of</strong> certain wastes which comprise or contain or are contaminatedwith oil. Classification is made according to international regulations for road <strong>transport</strong> - ADR (EuropeanAgreement Concerning the International Carriage <strong>of</strong> Dangerous Goods by Road - European agreement oninternational road <strong>transport</strong> <strong>of</strong> <strong>dangerous</strong> <strong>goods</strong>) 3 .THE TYPE OF WASTEUSED OILOther motor oils, gearoils <strong>and</strong> lubricationTable 2.

Thecomposition <strong>of</strong> used oils extremely varied depending on the source, <strong>and</strong> mixing <strong>and</strong> processing procedures.Samples <strong>of</strong> waste used motor oil, observed during the 2003rd by 2009. years were analyzed, the total concentration<strong>of</strong> 8 heavy metals (Cr, Cu, Zn, Ni, Cd, Pb, Ba, As) <strong>of</strong> which As, metalloid. Heavy metals are defined as elementsthat show the properties <strong>of</strong> metals (ductility, conductivity, stability as cations, etc.) <strong>and</strong> atomic number greater <strong>of</strong> 20They are important environmental pollutants <strong>and</strong> many <strong>of</strong> them are toxic even at very low concentrations.Samples <strong>of</strong> waste used oil is extracted, by 1 gr. oil is treated with 10cm³ in the ratio <strong>of</strong> 1:1 HNO 3 . The sample isheated with reflux from 10 to 15 minutes without boiling. After cooling, 5 cm³ concentrated HNO 3 , added to, <strong>and</strong>continues with heating by reflux for 30 minutes. Mixture evaporation to about 5 cm³. The sample is cooled, afterwhich it is added to water 2cm <strong>and</strong> 3cm³ 30% H 2 O 2 . The vessel is covered with sahat glass <strong>and</strong> heated again tobegin the reaction <strong>of</strong> peroxide. After cooling, H 2 O 2 (30%), added in 1 cm³ solution.
