NHL is Not Associated With Exposure to Gasoline
Twenty one of twenty two studies in the English literature that have examined the risk of non-Hodgkin lymphoma (NHL) among petroleum workers exposed regularly to gasoline have found no association between the two. The overall relative risk across all such studies has been estimated to be just 1.02.
