In recent years many waterways in Slovenia have been subjected to an increased loading with pesticides due to intensification of agriculture. The most widely used herbicides are atrazine and alachlor and they were detected in some rivers and even in ground water. Therefore the effects of atrazine and alachlor on selfpurification processes were investigated. The basic selfpurification processes studied were biodegradation of organic substances and photosynthesis and growth of algae. The inhibiting effect of pesticides on the process of biodegradation of organic pollutants was evaluated by the use of laboratory river model and mathematical modelling. The harmful impacts of pesticides on aquatic autotrophic organisms were assessed by measurement of net assimilation inhibition (24-h acute toxicity test) as well as growth inhibition - chlorophyll- a content (72-h chronic toxicity test) of algae Scenedesmus subspicatus. The results obtained demonstrate that atrazine and alachlor in concentrations found in our rivers have practically no effect on biodegrading heterotrophic organisms, while their adverse effect on algae is quite considerable.

This article use the Sulphide Isobutene (T321), Five Sufides Dialkyl(RC2540) and Star of Phosphorus(P110) as the additives,Neopentyl Polyol Ester(NPE) and mineral oil N32 as base oil. Compound above additives and base oil for the four levels. A sample: adding 4% T321 additive in NPE. B sample: adding 4% T321 additive in N32. C sample: adding 4% RC2540 additive in NPE. D sample: adding RC2540, T321 and P110 additives in NPE (all is mass fraction). The oral acute toxicity test, eye mucous stimulation test, skin hypersensitive test, soaking tail toxicity tests were conducted in above samples. The test results show that. The mineral oil, it’s not only toxic then synthetic oil but also has a poor lubricating ability compare with the same percent additive in synthetic oil. In oral acute toxicity test, eye mucous stimulation test, skin hypersensitive test, soaking tail toxicity tests, Toxic reaction of mineral N32+4%wt Sulphide Isobutene (T321) obviously from other oil samples.
