A model was established to relate the amount of naphthalene migrating from the surrounding air into milk contained in LDPE bottles after exposure to an environment having a considerable amount of naphthalene. Although the real situation is very complicated, the model was established by treating the case as involving migration into milk from a time‐dependent source of naphthalene, the equation for which is based on the increase with time in the naphthalene concentration in the LDPE bottles in the same environment. A model was then suggested to relate the amount of naphthalene migrating into milk with time as well as the naphthalene concentration in the surrounding air. Finally, the validity of the established model was checked for milk drinks exposed during storage to a naphthalene‐based moth repellent stored in a confined space.
