In each male, the following testicular lesions were scored: (1) hemocytic infiltration of the gonadal acini and phagocytosis of spermatogenic cells, (2) hemocytic infiltration of interacinal connective tissue, (3) aggregations of hemocytes under the mantle epithelium, and (4) occurrence of brown cells.
For example: a long exposure refers to a single, protracted shutter cycle to capture enough low-intensity light, whereas a multiple exposure involves a series of relatively brief shutter cycles; effectively layering a series of photographs in one image.
Exposure limits may be expressed as 8-hour time-weighted averages, or may be expressed for shorter exposures, such as ceiling levels or 15-minute short-term exposure levels. When necessary to assess and evaluate specific worker exposure or to investigate and resolve worker complaints or concerns.
