WORLD HEALTH ORGANIZATION INTERNATIONAL AGENCY FOR RESEARCH ON CANCER IARC MONOGRAPHS ON THE EVALUATION OF THE CARCINOGENIC RISK OF CHEMICALS TO HUMANS Polynuclear Aromatic Hydrocarbons, Part 2, Carbon Blacks, Mineral Oils (Lubricant Base Oils and Derived Products) and Some Nitroarenes VOLUME 33 This publication represents the 'hews and expert opinions of an IARC Working Group on the Evaluation of the Carcinogenic Risk of Chemicals to Humans which met in Lyon 7-14 June 19S3 April 1984 INTERNATIONAL AGENCY FOR RESEARCH ON CANCER yW OOOOlT MINERAL OILS1 (LUBRICANT BASE OILS AND DERIVED PRODUCTS) 1. Chemical and Physical Data 1.1 Synonyms and trade names Mineral oils (general) Chem. Abstr. Services Reg. No.: 8002-05-9 Chem. Abstr. Name: Petroleum IUPAC Systematic Name: Synonym: Petroleum distillate In view of problems of nomenclature and of the wide differences in the production, uses and cnemical, physical and toxicological characteristics of petroleum refinery materials, a system for defining petroleum crude oil refinery process streams was adopted in 1978 under the US Toxic Substances Control Act (TSCA) and in 1981 under the Commission of the European Communities's Sixth Amendment to the Dangerous Substances Directive - European inventory of Existing Commercial Chemical Substances (EINECS). Each stream is defined on the basis of petroleum crude oil type, viscosity and process, and is identified by a Chemical Abstract Services (CAS) Registry Number, which identifies its last refining process. The important refinery streams (most of which are used as lubricant base oils) that are included on the inventories of chemical substances in the USA and Europe are given in Table 1. A general term that nas oeen used to Gescnpe not only matenai covered in inis monograpn but crude petroleum and virtually all materials derived from it (e.g.. light naontna. gasoline, kerosene, middle distillates and fuel oils). Witnin ttus monograpn, the term luoncant base oils is used to refer to the refinery streams and the term lubncating oil' to the end product, as marketed, whicn is sold for lubncating purposes ana may or may not contain additives. -- 87 -- vvv 00G0I7616
