With the use of test-object experimental studies were conducted for the integral assessment of toxicinfluence of drill cuttings on living systems. It was studied how the extracts of substrata influence upon the length of theoats germs’ roots on the basis of the following structure of drill cuttings: native; drill cuttings + peat 1:1, drill cuttings +sand 1:1; drill cuttings + peat + sand 1:1:1 with the following dilutions 1:1; 1:10; 1:25; 1:50; 1:100. Both stimulating andinhibiting effects were studied. Maximum negative phytoeffect (-30%) was registered once under the influence of 100%drill cuttings extract (50-fold dilution). Addition of sand to drill cuttings decreased the inhibition; addition of peatstimulated the development of the test object (10-fold dilution). The combined effect of extracts of drill cuttings, peat andsand led to the appearance of maximum and minimum on the “Dose-effect” curve. It was confirmed to assign the 4thclass of hazard to the extract of drill cuttings.
