relative contribution of soil particles to the indoor environment and aid
with decision of appropriate mitigation procedures.
This is a field sampling based project to take water and breastmilk samples from women in Nogales, AZ and analyze them for TCE. A questionnaire is being developed to help identify risk factors. Ultimately, these results will be combined with a PBPK model for TCE in the infant and used to compute cancer risk from various routes of exposure.
The goals of this study are to utilize existing and archived population-based questionnaire and biological data that describe food and water consumption histories and exposures to construct predictive models for urinary arsenic biomarkers that can be used as indicators of arsenic exposure and health effect outcomes. Five publications were published in relation to this study. This was an EPA funded study.
The project provides public education, evaluates the content of private wells, and integrates the efforts of the College of Agriculture and Life Sciences, College of Pharmacy, and Mel and Enid Zuckerman College of Public Health.

This project is a small/pilot project program with the Southern California NIOSH Education and Research Center. This project was funded by University of California, Los Angeles (UCLA) through the CDC and NIOSH. For this project, I am serving as Ms. Sugeng's primary sponsor.
Melanoma is a public health concern since the incidence is increasing faster than any other cancer in the United States. While ultraviolet radiation is a widely accepted risk factor for this disease, understanding the possible role arsenic exposure may play in the development of melanoma will allow for a more developed base of knowledge regarding the etiology of melanoma.We will conduct a population-based case-control study of incident cutaneous melanoma (CM) cases and arsenic content detected in toenail samples.

This project will focus on the design of a miniaturized flow cytometer (a device for counting cells) for the detection of human viruses using engineered molecular beacons. These probes target unique microbial nucleotides, producing a fluorescent signal. This approach integrates optical detection systems for fast, quantitative signal measurement. Microfluidic systems reduce reagent volumes, system cost, size, and power requirements while addressing the need for rapid, real-time environmental monitoring and disease diagnostics.

Description: An increasingly militarized border region has deeply embedded immigration enforcement policy into the daily lives of residents, including farmworkers living and working in the region. Objective: The institutionalization of ethno-racial profiling in immigration and local law enforcement, and the sanctioned use of Mexican appearance as probable cause for citizen inspection is a potential structural determinant of health yet to be explored.
This project involved an Occupational Exposure Assessment and Inflammatory Biomarker Evaluation of diesel versus biodiesel emissions, specifically in underground mining. This project was funded by the National Institute for Occupational Safety and Health.
The goal of this project is to generate pilot data on the extrinsic incubation period for an important dengue vector. We used this to translate a mathematical model into MATLAB. This model is being used to investigate weather-related vector abundance for dengue, chikungunya, and West Nile virus vectors. Support for this project came from the University of Arizona Center for Insect Science.
The goal of this project is to 1) to demonstrate utility and feasibility of detection of LTBI among migrant farmworkers, and to compare outcomes in the US and Mexico and; 2)To assess follow-up of workers detected with LTBI and ability to link individuals to care. Through additional funding, we have been able to expand the work to include further care for participating migrant farmworkers in conjunction with the Migrant clinicians Network.
The quality of irrigation water drawn from surface water sources can vary greatly. This is particularly true for waters that are subject to intermittent contamination events such as runoff or direct entry of livestock upstream of use. Such pollution in irrigation systems increases the risk of food crop contamination. A single sample does not adequately characterize the risk potential present in large irrigation systems often utilized in the Southwestern US.
The goal of this study is to evaluate the efficacy of the XStream Infection Control system against viruses, bacteria and spores from the air, surfaces and human hand transfers. Microbial surrogates will be used to represent human enteric and respiratory viruses (i.e. influenza and norovirus), MRSA and other bacterial pathogens, and C. difficile spores. The resulting data can be used for the development of exposure and risk assessment models for determining the relative risk reduction in human populations following XStream Infection Control system use.
The goal of this proposal is to develop a Center for Indigenous Environmental Health Research (CIEHR), partnering with American Indian and Alaska Native (AI/AN) communities to build capacity to determine the contribution of chemical and other environmental exposures to health inequities and support efforts to address these threats. AI/AN communities suffer from increased mortality attributable to cancer (stomach, gallbladder, liver and kidney), respiratory disease, diabetes, and liver disease, among other conditions. Chemically contaminated traditional foods, water, air, and household env
Problem Statement and Justification: Mining remains a dangerous profession. Risk management is a cyclical process of identifying operations or activities at high risk for injuries, redesigning operating procedures to reduce risks, implementing these changes and evaluating their effectiveness. Internationally, risk management is a legal requirement in many countries, but in the U.S.
First Renewal of the Intergovernmental Agreement Between the City of Tucson and the Arizona Board of Regents: The Contractor shall provide specialized Services related to the development of new technology and methods for improved monitoring and detection of microbiological and chemical contaminants in the drinking water distribution system. These Services will improve Tucson Water's investigative capabilities by providing real...time contaminant data in the field.
Infections with Legionella have been steadily increasing over the past decade. Current strategies regarding Legionella have been focused on response-based approaches rather than prevention-based. Currently there are multiple resources available through different platforms that highlight guidelines and standards for Legionella prevention and water system management. The purpose of this study is to bring together the resources to create an interactive online training focused on preventative environmental health interventions.
Prenatal exposure to organophosphorus pesticides (OPs) has been associated with a wide range of adverse childhood outcomes –. However, most of these studies rely on OP biomarkers in the general population. These biomarkers disproportionately reflect non-toxic dietary ingestion of metabolites and cannot distinguish between parent pesticides. Exposure metrics that use agricultural pesticide applications may overcome these limitations, but such studies are limited to California.
