“…Studies of the chemical oxidation of substituted benzenes have indicated that ring degradation increases with increasing degree of alkyl substitution (27). Other studies of the metabolic products of n-, sec-, and fe/7-butylbenzene have indicated that oxidation of the ring as opposed to the branch will take place when a more highly substituted side chain is present (28). However, the authors are not aware of studies on the relative rate of metabolism of a ring or an alkyl substituent of a PAH that would allow conclusions regarding bioaccumulation.…”

The uptake of polycyclic aromatic compounds (PAC) from contaminated sediments into the muscle of finfish is described and modeled. Winter flounder (Pseudopleuronectes americanus) were exposed to various concentrations of Hibernia crude oil in sediments during 4 months in the winter. Concentrations of parental and specific alkylated PAC, including polycyclic aromatic hydrocarbons (PAH) and a polycyclic aromatic sulfur heterocycle (PASH, represented by dibenzothiophene, DBT) were determined in sediments and muscle. Commercially available specific alkylated naphthalenes, phenanthrenes, and anthracenes with known aqueous solubilities were quantified. PAH concentrations in sediments ranged from those expected in pristine areas to levels 25-50 times higher. Biota-sediment accumulation factors (BSAF) were deduced, showing that the more watersoluble PAH displayed higher BSAFs. A simple fugacity model describing the equilibrium and kinetics of uptake of chemicals from sediment suggests that the more soluble PAH are approaching equilibrium. However, the less soluble higher molecular weight PAH require a much longer time to reach steady state because of their low concentration in water.

initiated a programme on the evaluation of the carcinogenic risk of chemicals to humans involving the production of critically evaluated monographs on individual chemicals. The programme was subsequently expanded to include evaluations of carcinogenic risks associated with exposures to complex mixtures, life-style factors and biological and physical agents, as well as those in specific occupations. The objective of the programme is to elaborate and publish in the form of monographs critical reviews of data on carcinogenicity for agents to which humans are known to be exposed and on specific exposure situations; to evaluate these data in terms of human risk with the help of international working groups of experts in chemical carcinogenesis Publications of the World Health Organization enjoy copyright protection in accordance with the provisions of Protocol 2 of the Universal Copyright Convention.

IARC Library Cataloguing in Publication Data NOTE TO THE READERThe term 'carcinogenic risk' in the IARC Monographs series is taken to mean that an agent is capable of causing cancer under some circumstances. The Monographs evaluate cancer hazards, despite the historical presence of the word 'risks' in the title.Inclusion of an agent in the Monographs does not imply that it is a carcinogen, only that the published data have been examined. Equally, the fact that an agent has not yet been evaluated in a Monograph does not mean that it is not carcinogenic.The evaluations of carcinogenic risk are made by international working groups of independent scientists and are qualitative in nature. No recommendation is given for regulation or legislation.Anyone who is aware of published data that may alter the evaluation of the carcinogenic risk of an agent to humans is encouraged to make this information available to the Section of IARC Monographs, International Agency for...
