This study was undertaken in order to assess the environmental fate of Benzo (a) pyrene. We have
highlighted the behavior of Benzo (a) pyrene in multimedia environment or biosphere of air, water, soil and
sediments. Equilibrium Criterion (EQC) model which is used to evaluate the environmental fate of Polycyclic
Aromatic Hydrocarbons (PAHs) is used as our tool. The structure of the model and the required input data are
presented. By undertaking a sequence of level I, II and III calculations, increasing information is obtained about the
chemical’s partitioning, environmental process and chemical characteristics that influence chemical fate, its
susceptibility to transformation and transport from one media to another. Output data, consisting of diagrams, give a
complete picture of Benzo (a) pyrene’s fate in an evaluative environment. The role of this model as a tool for
assessing the fate of Benzo (a) pyrene is discussed. We suggested that this assessment can serve as a template which
can be applied to other chemicals and groups of chemicals which are present in the environment.
Key words: Benzo (a) pyrene, chemical fates, environment, EQC model, , ,
