Diclofop in runoff from agricultural watersheds in a high winter rainfall zone

Creator:: Hickman, John Spencer
Abstract:: Diclofop-methyl [me yl 2-(4-(2,4-dichlorophenoxy) phenoxy) propanoate] hydrolysis, degradation, and leaching were studied in field and laboratory experiments. Greater than 75% of the applied diclofop-methyl hydrolyzed to diclofop in 2 days at 4°C, the prevailing soil temperature during western Oregon winters. Degradation beyond the diclofop molecule, also an active herbicide, was...

Farm level response to agricultural effluent control strategies : the case of the Willamette Valley

Creator:: Taylor, Michael L. (Michael Lester), 1960-
Abstract:: Changes in the structure of the U.S. agricultural industry since World War II have transformed it into a highly productive component of the domestic economy. But these changes have not occurred without indirect costs. For example, the reliance on agricultural chemicals has produced environmental effects causing growing concern. In addition,...

Long-term fertilizer input influences total and bioavailable metal in agricultural soils and crops

Creator:: Pérez, Angela L.
Abstract:: Protection of the quality and integrity of food supplies is of global concern. Crops can accumulate non-nutritive and sometimes toxic metals and metalloids. Accumulated metals/metalloids can come in part, from fertilizers, which may contain variable levels of non-nutritive metals or metalloids such as arsenic (As), cadmium (Cd), lead (Pb), nickel...

Yesterday's orchard ... today's home : legacy pesticides on former orchard property

Creator:: Oregon State University. Extension Service, Stone, David L. (David Louis), and Anderson, Kim A.
Abstract:: Oregon has a rich history of orchard cultivation across the state. Today, orchards continue to be an important part of Oregon’s economy and contribute to a healthy and balanced diet for the public. But, with the growth of residential development, lands that once contained orchards are being converted into homes...

Effects of atrazine on olfactory-mediated behaviors in Pacific lamprey (Entosphenus tridentatus)

Creator:: Smith, April G.
Abstract:: Pacific lamprey (Entosphenus tridentatus) are experiencing population declines throughout their range. Xenobiotics could be an important risk factor for lamprey populations. Our goal was to establish if common herbicides, as used in forest management, could affect reproductive fitness. We determined that atrazine was a likely compound of greatest concern to...

Ruminal Biodegradation of Heterocyclic Toxic Compounds

Creator:: Tanaree, Dan D.
Abstract:: Cyclic nitramines are a class of compounds that include most of the commonly used explosives today. These are among the most common toxicants released into the environment as a result of human activity, generated on military ranges, battlefields, and production sites. Of these, hexahydro-1,3,5-trinitro-1,3,5- triazine (RDX) is of particular interest,...

Environmental estrogens and skeletal development disruption in the fathead minnow : A teleost model of vertebrate developmental toxicity

Creator:: Warner, Kara E.
Abstract:: Natural and synthetic estrogenic compounds detected in surface waters have been linked to endocrine signaling disruption in several species. Endogenous estrogen contributes to cartilage and bone deposition during development in vertebrates, and is susceptible to perturbation from xenoestrogens. The goals of this work were to develop a teleost model to...
