The NAEL of 7500 mg MEK/m3 (rat, 90 days) will be taken as a starting point. In view of the absence of long-term data and carcinogenicity data a safety factor of 10 is taken. Therefore, a OEL of 7500 : 10 mg/m3 = 750 mg MEK/m3 TWA 8 hr (250 ppm) is advised for exposure to MEK alone. Since skin absorption can add to the inhalatory exposure a "H" indication is advised. This value is above the odour threshold of detection; Biological monitoring it is advised to use as a BEI 2.7 mg MEK/l urine at the end of the workshift.

Ecotoxicology Modeling is a comprehensive and well-documented text providing a collection of computational methods to the ecotoxicologists primarily interested in the study of the adverse effects of chemicals, their mechanisms of action and/or their environmental fate and behavior. Avoiding mathematical jargon, the book presents numerous case studies to enable the reader to understand the interest but also the limitations of linear and nonlinear models in ecotoxicology. Written by an international team of scientists, Ecotoxicology Modeling is of primary interest to those whose research or professional activity is directly concerned with the development and application of models in ecotoxicology. It is also intended to provide the graduate and post-graduate students with a clear and accessible text covering the main types of modeling approaches used in environmental sciences.
