Testing Sonoma Ash and Air for Fire-Formed Pollutants

Tuesday, January 23, 2018

When fires ripped through suburban subdivisions in Santa Rosa last October, they may have done more than reduce homes to ashes. By incinerating all kinds of materials — insulation, electronics, furniture, cleaning products, pesticides — at very high temperatures, they could have created unknown or previously unrecognized health hazards in the smoke and ash. Researchers from the University of California, Davis, are trying to figure out just what is in that ash and air. Dr. Thomas Young, who is mentioned in the article, is the Associate Director of the Superfund Program and the Leader of Project 1.

Superfund Scientists Teach Elementary Students about Watershed Pollution

Saturday, May 17, 2014

On April 25th, a group of scientists from the UC Davis Superfund Research Program (SRP) and the UC Davis Aquatic Health Program braved the rainy weather to participate in Marguerite Montgomery Elementary School (MME)'s Science Fair. The grey sky and constant drizzle, however, was an unexpected boon that helped the scientists to explain the topic of this year’s exhibit: watershed pollution. The team of scientists led a ten-minute interactive workshop for 2nd and 3rd graders about watersheds and potential pollution sources (such as litter, pet feces, agricultural run-off, car pollution, etc.). Locally, this is very important since Davis is located in one of many watersheds that washes out into the Sacramento-San Joaquin Delta, which consequently is a substantial part of the statewide water system. Pollution in this watershed may have drastic consequences to human and environmental health. After understanding how pollution from the landscape could be washed into rivers and then the ocean when it rained, students learned how these substances could harm marine wildlife. The scientists used stuffed animals – a copepod, fish, and killer whale – as members of a food chain. Students quickly caught on to the problem: not only does the killer whale get the largest dose of toxin, but humans are also part of that marine food chain.


When asked how to prevent this pollution from harming animals (and humans!), students had some creative answers: “use a policeman to stop people from polluting,” “become an ‘environmentalogist,’” and, finally, “clean it up before it can go into the river!” It sounds like they have the right idea.

Spreading the word about toxin exposure: Superfund research highlighted at the annual UC Davis Picnic Day

Friday, April 18, 2014

On April 12th, 2014, UC Davis celebrated its 100th Picnic Day, a celebration of its agricultural roots and of its premier research facilities and projects. The UC Davis Superfund Research Program (SRP) again took advantage of this tremendous opportunity to engage with the public and developed an exhibit to inform the public about their research and their mission. Graduate students Sean Kodani and Erika Fritsch, as well as Research Translation Core Leader Dr. Candace Bever and intern Allison Dycaico, led an exhibit which focused on how organisms accumulate toxins through the food chain via the ecological processes known as bioaccumulation and biomagnification. This year, the UCD SRP invited the Oregon State University (OSU) SRP to participate, which included Training Core Leader, Dr. Craig Marcus, and trainees Andrea Knecht and Erin Madeen. Alongside the UCD SRP exhibit about biomagnification and daily toxin exposure, the OSU SRP presented posters about their research on polycyclic aromatic hydrocarbons (PAHs) in smoked meat prepared by Native Americans and the effect of PAHs on development in zebrafish.

2014 Current News Postdoctoral Researchers participate in Career Day at local school

Friday, February 07, 2014

No two career paths are the same. Sacramento's School of Engineering & Sciences is very aware of this concept and so each year, they invite two speakers to each of their 7th-11th grade classrooms. This year, two postdoctoral scholars from the UC Davis Superfund Research Program, Amy Rand and Candace Bever, participated in the school's annual Career Day. Both of these postdoc researchers were assigned to different classrooms and paired with a more senior colleague in order for the students to gain different perspectives of both career paths. Amy brought in props, such as a non-stick cooking pan and a raincoat, to illustrate how her research involves everyday items. Candace punctuated her career path experiences by reminding the students that you won't always be successful in every application, but you have to put in an application in order to have a chance at obtaining that position. Both speakers were commended by their fellow professionals as exhibiting fearless enthusiasm and being natural teachers. Thank you, Amy and Candace, for taking time to inform others about your career path and by inspiring the next generation of scientists and engineers!

This research will help Amy and her team to further clarify the specific relationship between the dietary exposure to and metabolism of omega-3 fatty acids and their role in the regulation of certain cancers

Consumer Products giants are removing triclosan and other harmful chemicals from their products

Wednesday, September 04, 2013

By the end of 2014, Procter & Gamble will eliminate triclosan from its personal care and other household products.  Johnson & Johnson states that they, too, are looking to phase out triclosan from their adult products by the end of 2015-- their beauty and baby care products already do not contain triclosan.

Triclosan is an antibacterial ingredient used to prevent the growth of germs. It is also a chemical of concern that the UC Davis Superfund Research Program studies to better understand its potential health effects. Scientists from our Program found that triclosan impairs muscle function in fish and mice and stated the results they found show “strong evidence that triclosan could have effects on animal and human health at current levels of exposure.”

Other chemicals targeted for removal include parabens, 1,4-dioxane, formaldehyde-releasing perservatives, and phthalates. You can read more related topics here: Campaign for Safe CosmeticsBeyond Pesticides

UC Davis Scientists Reveal Clues Linking Bisphenol A (BPA) Exposure to Lung Disease

Thursday, August 01, 2013

Exposure to bisphenol A (BPA) has been shown to alter the development of reproductive organs, but little is known about its impacts on other organ systems. This paper on BPA health effects is important because it shows an effect in a non endocrine organ, the fetal lung, at circulating levels similar to humans. The authors found BPA increases MUc5B, a mucin, that is found in mucous cells. Increases in mucous cell abundance are a hallmark of asthma. Recent epidemiology studies show a link between neonatal BPA exposure and asthma. While this study is not conclusive in linking BPA to asthma or AHR (airways hyperresponsiveness), as there is no long term follow up on the exposed fetus, it provides an important clue about how BPA alters lung development, which in turn may predispose to airway disease.

Trainees Provide a Science Demostration for a Local Elementary School

Wednesday, May 08, 2013

UC Davis Superfund Enthusiasts, including Investigators, Trainees, and Staff, participated in César Chávez Elementary (K-6) School's Biannual Science Fair called Festival de Ciencias 2013. The UC Davis Superfund Team presented an interactive exhibit which allowed the students to see an oil spill and construct sorbent booms to clean it up. Much to the children's surprise, the booms were nylon stockings stuffed with dog hair. The demonstration showed how effective this material was in cleaning up oil spills and helped lead discussions of other technologies used in oil spill clean up. Further discussions ensued regarding how oil spills are harmful to the environment and wildlife.

Superfund Poster Educates Picnic Day Visitors about Household Toxins

Saturday, April 20, 2013

Davis, CA basked in the ripe heat of spring this Picnic Day as thousands flocked to the 99th annual gala of cow milking, cockroach racing, and pitbull kissing. Tucked in the air-conditioned cool of Meyer Hall, UC Davis' Superfund Research Program (SRP) engaged Picnic Day attendees with a different kind of exhibit—one that left them better-informed of household toxins.

SRP’s interactive “Hide and Seek” poster prompted visitors to find the hidden toxin (under flaps) and seek its respective solution (on the side panels). Since SRP investigates hazardous waste and its impact on human health, the poster aimed to inform audiences of everyday toxins that might be lurking in their homes. Pharmacology and Toxicology graduate students Sean Kodani and Lindsey Curley moderated the poster exhibit throughout the day.

“You kind of have to ring people into the conversation,” said Kodani. “But when you do, you get people from all different levels of knowledge interested in finding out more, because it’s so relevant to their lives.”

UC Davis Researchers' Key Discovery Involving Omega-3 Fatty Acids and Cancer

Tuesday, April 02, 2013

Researchers at the University of California, Davis have discovered a key mechanism by which dietary omega-3 fatty acids (fish oils) could reduce the tumor growth and spread of cancer, a disease that kills some 580,000 Americans a year.


In groundbreaking research, the team of 16 scientists led by Dr. Guodong Zhang of the Bruce Hammock laboratory, Department of Entomology and the UC Davis Comprehensive Cancer Center, discovered cytochrome P450 epoxygenase metabolites of omega-3 fatty acid DHA or epoxy docosapentaenoic acids (EDPs) block blood supply to the tumor and thus inhibit tumor growth and metastasis.

The natural EDPs were further stabilized by a drug called a soluble epoxide hydrolase inhibitor which is already under development to control pain and hypertension. The research is to be published the week of April 1-5 in the Proceedings for the National Academy of Sciences (PNAS). The studies, conducted on mice, also suggest that a combination of omega-3 diet and some anti-cancer drugs such as sorafenib.

Other co-authors of the paper in addition to Hammock were Jun Yang, Jun-Yan Liu, Kin Sing Stephen Lee, Arzu Ulu, and Sung Hee Hwang, all of the UC Davis Department of Entomology and UC Davis Comprehensive Cancer Center; Lisa Mahakian, Xiaowen Hu, Katherine Ferrara, Sarah Tam, and Elizabeth Ingham, UC Davis Department of Biomedical Engineering; Hiromi Wettersten of the UC Davis Division of Nephrology, Department of Internal Medicine; Robert Weiss, Comprehensive Cancer Center, Division of Nephrology and U.S. Department of Veterans’ Affairs Medical Center, Sacramento; and Dipak Panigrahy and Mark Kieran of the Vascular Biology Program, Children’s Hospital, Harvard Medical School.

Cell Biologist Dr. Henry Sun gave tips to UC Davis Grad Students about Survival Skills for Young Investigators

Monday, June 18, 2012

World-renowned cell biologist and former UCD Ph.D. student Dr. Henry Sun gave a workshop to graduate students on June 16 on how to be successful in doing research. He did this during a visit in 2000 that was a smashing suceess and got rave reviews from the students and faculty in attendance. That experience inspired him to develop his ideas more fornally, leading to a Nature article and development of a workship. 


This year, the workshop was again very well-received and was attended by 100 people comprised mostly of graduate students, but postdoctoral scholars, faculty and staff were also in attendance. The one-day workshop covered topics including experimental design, scientific writing, grant writing and oral presentation.
