Summer is the season for pesticide use

Okay, no one really enjoys using pesticides. But in Summer, bugs crawl, weeds grow, mosquitos bite and…..well, you get what I mean. So, since pesticide use is common in Summer, we all need to know how to use them in a manner that reduces health risks, to ourselves, our loved ones, to non-targeted species (e.g. pollinators) and to the general environment. Notice I didn’t use the word “safe”, because “safe” doesn’t belong in the vocabulary … Read More

Multiple agencies meet to discuss pesticide issues

Pesticides are a commonly used tool for the control of a variety of pests, including weeds, bacteria, insects, rodents and molds, and represent a potential health risk to those who use them. Oregon OSHA is actively involved in ensuring that safe work practices with pesticides are followed, and provides a variety of educational and consultation services in this regard. Last week, Oregon OSHA sponsored the 2016 Oregon Pesticide Symposium, which was held March 15-16 at the Chemeketa … Read More

AWWA is all about water

It is easy to take for granted the access to clean and safe water that we all enjoy. But without the experts who design, construct, operate and manage the utilities that provide our water, this luxury would not exist. This week, I had the privilege of addressing our regional water professionals at the 32nd annual American Water Works Association (AWWA) Pacific Northwest Section Cascade to Coast Short School, held March 13-16 at the Valley River … Read More

Research paper reveals effects of enzyme loss

  Glial expression of Swiss-cheese (SWS), the Drosophila orthologue of Neuropathy Target Esterase, is required for neuronal ensheathment and function, by Dutta S, Rieche F, Eckl N, Duch C, and Kretzschmar D. That’s the title of a paper, recently published, that describes work originating from the laboratory of Doris Kretzschmar. In this work, Dr. Kretzschmar and postdoctoral fellow Sudeshna Dutta created a genetic mutation in a fruit fly enzyme that is analogous to neuropathy target … Read More

Arsenic and cadmium air pollution found in SE and North PDX

Potentially unsafe levels of arsenic and cadmium have been detected in the air of Southeast Portland. The primary source was been localized to a glass production facility that has operated there for ~40 years. They have since terminated use of these metals in their process, so there is no current risk of continued airborne exposure from this source. A similar finding has been localized to a glass production facility in North Portland, who has also … Read More

Asian gypsy moth makes appearance in Portland

In 2015, Asian gypsy moths (AGM), a plant-eating invasive species, were detected in Portland’s Forest Park and northern part of the St Johns neighborhood. The moths were found during routine monitoring in traps placed throughout the region by the Oregon Department of Agriculture. A related species, the European gypsy moth (EGM), was also found. EGM is endemic to the northeastern United States, has defoliated millions of acres of trees and shrubs, and since the late … Read More

VA changes policy on Agent Orange-exposed AF Reserve veterans.

During the Vietnam war, approximately 20 million gallons of herbicides, including about 10.5 million gallons of dioxin-contaminated Agent Orange, were sprayed in South Vietnam to deprive the Viet Cong of food as well as jungle cover. The 30-40 Fairchild C-123 aircraft used in this operation were subsequently returned to the United States and reassigned, without proper decontamination, to Air Force Reserve units for use in transport and aeromedical operations. Between 1972 and 1981, as many … Read More

New pesticide fact sheets from ODA

Improper use of pesticides in the home, on the farm, or in a forest can harm people, animals and the environment. The Pesticide and Analytical Response Center (PARC), a program operated by the Oregon Department of Agriculture’s Pesticides Division, and the Oregon Health Authority, have collaborated in the production of two fact sheets that explain what to do and who to call if you are concerned about an application or have actually been exposed to … Read More

Another successful PhD graduate!

Congratulations to newly minted PhD Stacey Lin for successfully defending her graduate thesis, which explored the mechanisms by which a potent liver carcinogen, Aflatoxin B1 (AFB1), produces DNA mutations that eventually lead to cancer of the liver. She is interested in the mutagenic spectrum of AFB1 and the ability of cells to bypass and repair genetic damage. The results of Stacey’s work opens new avenues of research that will allow scientists to further probe and understand … Read More

Oregon Institute of Occupational Health Sciences Holds Science Retreat

The Oregon Institute of Occupational Health Sciences (formerly CROET) faculty held a Science Retreat on Wednesday, October 30, to discuss their mission and research themes, and to learn from the OHSU Foundation about ways that the Institute can gain philanthropic support. Led by Director Steve Shea, PhD, the Retreat began with a discussion about why we are committing our careers to occupational health and safety.  Why do we do what we do.  Faculty conducting basic … Read More
