Groundwater arsenic concentrations and cancer incidence rates : a regional comparison in Oregon

Creator:: Fleming, Harmony S.
Abstract:: Arsenic contamination of groundwater is a global issue with national and local implications. Chronic exposure to arsenic in drinking water has been linked to both carcinogenic and non-carcinogenic health outcomes. The primary exposure route of inorganic arsenic is ingestion from drinking water due to natural contamination in groundwater from dissolution...

The agronomic, environmental, and economic implications of the introduction of terbacil for weed control in Oregon commercial peppermint operations

Creator:: Harris, James O.
Abstract:: The use of terbacil for weed control was adapted by a high percentage of Oregon peppermint growers soon after its introduction in 1967. To help clarify some of the implications of terbacil usage, three studies were undertaken to collect information concerning (a) the movement and build-up of terbacil in various...

An analysis of two adjacent agricultural watersheds in west central Oregon

Creator:: Schoeneberger, Philip James
Abstract:: Two small adjacent watersheds on the west-central edge of the Willamette Valley of western Oregon were studied. Information was gathered on existing conditions to determine the suitability of the two watersheds for a paired-watershed study design. A soil survey was conducted using slightly modified soil series previously established for the...

The accumulation of cadmium, copper and nickel in freshwater mussels (Margaritifera margaritifera), algae (Cladophora sp.), and sediment from Elk Creek, Oregon

Creator:: Sigismondi, Linda A.
Abstract:: Concern about heavy metal pollution has increased during the past decade in which studies have shown that heavy metals are accumulating in the environment and that these metals, in excess, are toxic to organisms, including man. Because of this concern, scientists have suggested the use of indigenous organisms as monitors...

Fine organic debris and dissolved oxygen in streamed gravels in the Oregon Coast Range

Creator:: Skaugset, Arne E.
Abstract:: Intragravel organic loading and intragravel dissolved oxygen were studied to determine the relationship between timber harvesting adjacent to first-, second-, and third-order streams and intragravel water quality. Twenty watersheds in the central Coast Range of western Oregon were studied of which five were undisturbed, nine were partially harvested, and six...
