Description: Given the cost and popularity along with the uncertainty/variability in data quality, the use of air sensors for a given application requires an understanding of the data quality of these devices. This can be done either in the laboratory or in-situ in the field, both of which have their advantages and disadvantages. The advantage of a field study is that it portrays real world conditions along with interferences from a complex mixture of pollutants. Field deployment of sensors along with a co-located reference monitor allows for direct assessment of the data quality performance of the sensor devices.
Learning Objectives: This course will demonstrate the basic steps of a co-location analysis from data already collected. Such an analysis not only illuminates the performance of the given sensors, but could be used to re-calibrate the instruments to provide improved performance. The analysis will consider various performance parameters such as precision, accuracy, error and discuss effects of temperature and relative humidity.
Attendees of this course will utilize collocated reference and sensor data and evaluate performance based on several metrics. Data will already be uploaded online and an R Shiny package will be used for analysis. Data from several sites are likely to be used to illustrate issues. The instructors will also discuss other issues such as:
1. Logistics: Permissions, space concerns and distance from other instruments’ sample inlets, insurance, safety, power, networking, access, etc.
2. Choice of colocation site: how representative is the colocation site’s environment with the environment that the monitor will eventually be located? Discussion of the different types of sites (regional, near-roadway, etc.) that are operated by gov’t, as this often conditions the instruments and pollutant species that are collected there.
3. How long should the colocation be? Re-colocation/re-calibration?
4. Do all monitors need to be collocated/calibrated within a study/region?
5. Measuring other covariates to understand sensor performance/calibration? E.g., temperature, humidity
6. Identifying sensor limits of detection (high or low) and/or non-linear sensor response from colocation data.
7. Identifying sensor drift or failure from colocation data.

Description: The public looks to health care providers for expertise in environmental health. Unfortunately, physicians receive very little formal training regarding environmental exposures and even less on the relationship to health outcomes. Medical school curricula are increasingly including instruction on social determinants of health as these factors are accepted influences for poor health outcomes. Building from this, attendees of this 2-hour workshop will learn how to use the US EPA’s EJSCREEN Environmental Justice Screening and Mapping Tool, in conjunction with publicly available health outcome data to teach medical professionals the relationship between environmental exposures (lead-based paint and air pollution), social factors (race, economic status) and poor health outcomes, such as lead poisoning, asthma, and shortened life expectancy. As health educators and students may not have access to GIS applications or methods, the tools needed for this activity are an internet browser and a spreadsheet application with mapping capabilities such as Microsoft Excel.

Description: There is an increasing need for methods to assess exposure and related impacts of toxic chemical emissions on human health and ecosystems including consumer exposure. This course provides a practical overview of multimedia chemical fate modelling, near-field and far-field multi-pathway human exposure modelling, ecosystem and human health effects dose-response modelling, and comparative indicators for human-toxicological and ecotoxicological impacts. We explain basic concepts of environmental mass balance modelling including partitioning, first order cross-media transport, and persistence. We further introduce the concept of assessing multiple transfers between near-field and far-field environments and resulting exposures for consumers and the general population, discussing data and models available for detergents, building materials, food contact materials and personal care products. Along a series of practical examples, we will illustrate how fate, exposure, effect and damage factors can be combined to construct factors to characterize chemical emissions and chemicals in consumer products, building on the USEtox scientific consensus model and USEtox-compatible near-field models. We will conclude with a demonstration of how the models can be used in various applications, including the prioritization and ranking of chemicals for institutions like the European Commission or the U.S. Environmental Protection Agency.
Course Objectives
The aim of this course is to introduce participants to the exposure science methods used in life-cycle and comparative risk assessments. Participants will learn to use and evaluate basic tools for mass-balance, fate modelling, near-field and far-field exposure and intake fraction, and effect factor estimation. Participants will review underlying model assumptions and evaluate data needs along with data and knowledge gaps in these assessments.
The course is intended for environmental science practitioners interested in the scientific fundamentals of chemical impact assessment for a broad range of environmental emissions. Only basic background knowledge of environmental modelling, risk assessment or life cycle assessment is considered necessary.
Participants will come away with knowledge of basic concepts of consumer and population exposure science for chemical impact assessment and be able to perform their own assessment using the latest release version of the scientific consensus model USEtox and related near-field models, and interpret results for their own application context.
Target Audience
The course is for PhD students, professionals and practitioners interested in state-of-the-art mass balance-based tools for use in life cycle impact assessment, human and ecological toxicity assessment, consumer exposure assessment, risk screening, chemical substitution and prioritization. No specific previous knowledge is required.

Description: Data visualization is critical to conveying new findings in environmental health and is a vital part of advancing the field of environmental epidemiology around the globe. There are a variety of options for creating figures with licensed software, but data visualization packages like ggplot2/R are easily accessible and economical alternatives that can produce high quality and journal-ready figures. The syntax of ggplot2 is challenging to learn, so this workshop aims to allow participants to become comfortable with the syntax of ggplot2, create elegant, complex figures, and be comfortable applying the skills learned to their own research projects.
This workshop, led by a diverse, all-female panel of new researchers, will offer live-coding and interactive examples using R statistical software. This session will begin with a brief introduction to the ggplot2 package and supporting packages. Next, we will cover general practices for manipulating data structures and data formatting for creating ggplots. We will spend the majority of the workshop introducing examples of various plots that are frequently used in environmental epidemiology, focusing on the following aspects:
• Adding confidence intervals to point estimates;
• Manipulating background, axis, titles, legends, colors, themes;
• Creating maps;
• Saving and exporting high quality figures for presentations and publications.
We assume that participants will have some experience in statistical programming. No prior experience with ggplot is necessary, but this workshop is not meant to be an introduction to R.
