Abstract:: An abandoned cinnabar mining and roasting site is in the major sub-basin of the watershed for Cottage Grove Reservoir, Oregon. Average surface sediment total mercury concentration in the river draining this sub-basin (0.61±0.52 μg /g) was about ten-fold higher than three smaller tributaries to the reservoir. Total mercury in reservoir...

Creator:: Vorderstrasse, Beth A.
Abstract:: T cell-dependent immune responses are highly sensitive to suppression by exposure to the environmental contaminant 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), yet direct effects of TCDD on T cells have been difficult to demonstrate. Because the activation of naive T cells is initiated by dendritic cells (DC), the studies presented in this dissertation were...

Creator:: Ruby, Carl E.
Abstract:: In experimentally exposed mice, the environmental contaminant 2,3,7,8 tetrachlorodibenzo-p-dioxin (TCDD) produces significant suppression of adaptive immune responses at low doses. However, the underlying biochemical and cellular mechanisms of TCDD-induced immunotoxicity have remained elusive since the identification of these effects nearly 30 years ago. Antigen-presenting cells (APC) constitute various populations of...
