Hoh Environmental Health Laboratory
Professor Eunha Hoh, Ph.D.
School of Public Health, San Diego State University
A description of our research can be found in the following SDSU NewsCenter articles and videos:
Example projects are:
- Assessment of thirdhand cigarette smoke pollution. This project is a collaboration with Dr. Georg Matt, SDSU Department of Psychology and Dr. Penelope Quintana, SDSU School of Public Health.
- Identification of contaminants potentially affecting the conservation of California condors. This project is a collaboration with Drs. Christopher Tubbs and Ignacio Vilchis of the San Diego Zoo.
- Studying the degration of oil released by the Refugio spill. This project is a collaboration with Dr. Natalie Mladenov, SDSU College of Engineering.
- Evaluation of Decentralized Water Treatment Systems (DEWATS) by non-targeted mass spectrometry. This project is a collaboration with Dr. Natalie Mladenov, SDSU College of Engineering.
As reported in the Los Angeles Times, research by multiple groups has found some of the most abundant environmental contaminants in southern Califorina marine mammals are related to the historical disposal of DDT waste in the ocean and are associated with elevated cancer rates in sea lions. A set of our projects measure contaminants in California marine mammals to determine their suitability as sentinel species for biomagnifying compounds and have investigated DDT in particular. In April 2021, Dr. Hoh participated in a congressional briefing on southern California DDT waste dump sites (PDF).
Dr. Hoh is a member of the California Ocean Protection Council's Science Advisory Team, an expert interdisciplinary group formed to address issues impacting the state's coastal and marine ecosystems.
- An OPC Microplastics Working Group co-chaired by Dr. Hoh released their recommendations and risk assessment framework in May 2021, suggesting California be precautionary in managing microplastic pollution until the science can better quantify the effects. Report (PDF).
Dr. Hoh is a member of the California Environmental Contaminant Biomonitoring Program Scientific Guidance Panel. The role of the panel is to:
- Make recommendations regarding the program's design and implementation. This includes making specific recommendations regarding chemicals that are priorities for biomonitoring in California.
- Provide scientific peer review for the California Environmental Contaminant Biomonitoring Program.
Our recent journal article Cannabis and the Environment: What Science Tells Us and What We Still Need to Know was selected as an ACS Editors' Choice article (2021).
Our journal article Assessing Toxicity and in Vitro Bioactivity of Smoked Cigarette Leachate Using Cell-Based Assays and Chemical Analysis was selected as an ACS Editors' Choice article (2019).
The Hoh Laboratory is a member of the SDSU Blue Gold Area of Excellence.
Research projects are funded by NIH, NSF, NOAA, California SeaGrant, and the California TRDRP.
