Three basic stages of the chemical safety assessment process have been discussed in the publication: hazard assessment, exposure assessment and risk characterization. In the framework of hazard assessment among others the threshold levels for exposure considered as safe have been mentioned and discussed. By discussion concerning exposure assessment, the role of the exposure scenarios and the way of approach to the real human exposure levels and predicted environmental concentration as the reference values to the no harmful effect threshold levels have been described. Then the way of risk characterization and cyclic achievement of acceptable risk level have been talked over and, by extension elaboration of the final exposure scenario which may be applied for downstream users in the supply chain to create safe substance handling conditions – has been discussed....

In relation to the REACH procedures, the producers and importers have to deliver registration documentation, containing information about chemical substance, especially about its toxic and ecotoxic properties. The paper presents selected results of toxicological and ecotoxicological tests of liquid fuel additive. The results will be required in the subsequent stage for compilation of chemical safety assessment and report.

Ethyl alcohol (ethanol), CAS No1: 64-17-5, EC No2: 200-578-6, is a chemical substance applied first of all in the food industry for the vodka and liquors manufacturing in the spirituous branch, and also as an additive for making some selected sweetmeats, cakes, layer cakes and food fragrances. This way of use prevails in Poland. It should be not forgotten that ethanol belongs simultaneously to the most important basic solvents for both organic and inorganic substances used in the chemical, cosmetic and pharmaceutical industries, in this latter as a raw material for production of numerical medicaments. As an additive to the gasoline is used as an engine fuel. Main suppliers of this feedstock for spirituous branch in Poland are distilleries making raw ethyl alcohol in the process of alcoholic fermentation of agri-...
