Chronic Exposure 03
Chronic Exposure 03 : A continuous or intermittent exposure of an organism to a stressor (e.g., a toxic substance or ionizing radiation) over an extended period of time or significant fraction (often 10% or more) of the life span of the organism. Generally, chronic exposure is considered to produce only effects that can be observed some time following initial exposure. These may include impaired reproduction or growth, genetic effects, and other effects such as cancer, pre-cancerous lesions, benign tumors, cataracts, skin changes, and congenital defects
