Carcinogenesis studies in rodents for evaluating risks associated with chemical carcinogens in aquatic food animals.

abstract：BACKGROUND:Although numerous epidemiologic studies now use models of intraurban exposure, there has been little systematic evaluation of the performance of different models. OBJECTIVES:In this present article we proposed a modeling framework for assessing exposure model performance and the role of spatial autocorrelat...
