Cumulative risk assessment
This chapter focuses on the potential of cumulative risk assessment (CRA) to improve policy decisions about environmental justice. The collective nature of CRA embodies several contemporary and distinct ideas. First, harmful entities (e.g. environmental stressors, levels of toxicity), events (e.g. duration and frequency of exposure), and outcomes (e.g. discomfort, dysfunction, disability, disease) accumulate, causing aggregate quantities of multi…
Concurrent Fetal Exposure to Multiple Environmental Chemicals along the U.S.—Mexico Border: An Exploratory Study in Brownsville, Texas
There is mounting concern that cumulative exposure to diverse chemicals in the environment may contribute to observed adverse health outcomes in the Lower Rio Grande Valley of Texas. To investigate this situation, biomarker concentrations of organochlorine (OC) pesticides/metabolites, polychlorinated biphenyls (PCBs), and polycyclic aromatic hydrocarbons (PAHs) were measured in maternal and umbilical cord blood from pregnant Hispanic women in Bro…
Socioeconomic Context and the Food Landscape in Texas: Results from Hotspot Analysis and Border/Non-Border Comparison of Unhealthy Food Environments
Identifying the relationship between socioeconomic disparity, ethnic concentration and mRFEI score could be a fundamental step in improving health in disadvantage communities, particularly those on the Texas-Mexico border
Biomarkers of Maternal and Fetal Exposure to Organochlorine Pesticides Measured in Pregnant Hispanic Women from Brownsville, Texas
Biomarkers of organochlorine pesticides were measured in both venous and umbilical cord blood from 35 pregnant Hispanic women living in Brownsville, Texas, USA. Gas chromatography with an electron capture detector was used to analyze specimens for 30 individual pesticides or their metabolites. Results indicate that blood concentrations were relatively low for most individual compounds, but that high-end (upper 10th percentile) values for total DD…
Application of a Novel Method for Assessing Cumulative Risk Burden by County
The purpose of this study is to apply the Human Security Index (HSI) as a tool to detect social and economic cumulative risk burden at a county-level in the state of Texas. The HSI is an index comprising a network of three sub-components or "fabrics"; the Economic, Environmental, and Social Fabrics. We hypothesized that the HSI will be a useful instrument for identifying and analyzing socioeconomic conditions that contribute to cumulative risk bu…
Impact of Hispanic Ethnic Concentration and Socioeconomic Status on Obesity Prevalence in Texas Counties
The purpose of this study is to determine whether Hispanic ethnic concentration is associated with a higher prevalence of obesity and, if this relationship exists, whether it is affected by the socioeconomic environment. The study uses the Texas Behavioral Risk Factor Surveillance System (BRFSS) linked to 2000 census data to access the relationship between prevalence of obesity, Hispanic ethnic concentration, poverty and level of education at a c…
Health inequities in environmental justice communities: Relevant indicators to reflect a variety of health threats
Residents of environmental justice (EJ) communities often suffer significant health inequities due to pollutants and to adverse social conditions. However, methodologies for assessing such communities seldom account for both kinds of factors. While traditional environmental health risk assessments use single-pollutant, single-source measures of chronic risk alone, this project develops a technique for assessing "overall risk burden" in EJ communi…
Cumulative Risk Assessment for Combined Health Effects From Chemical and Nonchemical Stressors
Cumulative risk assessment is a science policy tool for organizing and analyzing information to examine, characterize, and possibly quantify combined threats from multiple environmental stressors. We briefly survey the state of the art regarding cumulative risk assessment, emphasizing challenges and complexities of moving beyond the current focus on chemical mixtures to incorporate nonchemical stressors, such as poverty and discrimination, into t…
Conceptual Models for Cumulative Risk Assessment
In the absence of scientific consensus on an appropriate theoretical framework, cumulative risk assessment and related research have relied on speculative conceptual models. We argue for the importance of theoretical backing for such models and discuss 3 relevant theoretical frameworks, each supporting a distinctive “family” of models. Social determinant models postulate that unequal health outcomes are caused by structural inequalities; health d…
Stakeholder Participation in Voluntary Environmental Agreements: Analysis of 10 Project XL Case Studies
This article examines stakeholder involvement and influence as part of voluntary environmental agreements between regulatory agencies and companies. Ten pilot projects that were part of the U.S. Environmental Protection Agency's Project XL (excellence and leadership) were examined to evaluate process goals (fairness and competence) and outcome goals (trust and incorporation of public values in decisions). The ten case studies encompass a range of…

Indoor Air Quality: An Overview of Policy and Regulatory Issues
Historically, nonindustrial indoor environments-residential, commercial, institutional, and public buildings-have been considered relatively nonhazardous. During outdoor air pollution episodes, small children and individuals with respiratory illnesses are encouraged to stay indoors. Although this practice may be good advice if the goal is to reduce human exposures to photochemical oxidants (such as ozone), there is increasing evidence that concen…
