Introduction to Aerosols 1: Particle Aerodynamics, Diffusion, and Size Measurement

Abstract: This tutorial is the first of two that introduce the broad field of aerosol science. We begin with the behavior of individual particles to understand how they behave in the environment, and the physical principles on which most aerosol measurements are based. The drag forces that act on a particle determine its settling velocity and whether it is able to follow the flow of a gas. Several different models describe the drag forces: Stokes law applies for spherical particles moving at modest velocities, though a slip correction must be introduced to account for non-continuum effects for particles small compared to the mean-free-path of the gas molecules. Other corrections are required if the velocity becomes large enough the fluid inertia affects the motion. Knowledge of these scaling principles makes it possible to relate particle behavior in seemingly disparate systems and make it possible to determine particle size. The drag forces also determine Brownian motion, and, hence, affect their deposition and losses in the respiratory tract, in sampling systems, and in filters, causing aerosol filtration to be more effective than filtration of particles from liquid media. We will briefly look at how this aerodynamic behavior is employed in determining particle size in a wide range of instruments, including the migration of charged particles in mobility analyzers.

Nano in the Home: Measurement and Modeling Techniques for Characterizing the Dynamics of Ultrafine Particles in Indoor Environments.

Abstract: An important class of indoor aerosols are ultrafine particles (UFPs) - particles smaller than 100 nm in size. UFPs are the most numerous particles in the indoor atmosphere. UFPs penetrate deep into our respiratory systems and preferentially deposit in both the tracheobronchial and alveolar regions of our lungs. Indoor sources of UFPs are ubiquitous, ranging from candles and gas stoves to 3D printers and terpene ozonolysis. This tutorial will introduce you to measurement and modeling techniques for characterizing the dynamics of UFPs in indoor environments. You will learn how to evaluate the emissions/formation of UFPs, UFP transformations due coagulation and condensation, and UFP removal via deposition, filtration, and ventilation. The tutorial will include hands-on activities with various aerosol instrumentation.

Generation and Sampling Techniques for Bioaerosols

Abstract: Biological aerosols are comprised of particles containing bacteria, fungal spores, hyphae pollen, algae, proteins, viruses, and fragments of the above. They have wide-ranging impacts ranging from human disease and allergies to potential impacts on the water cycle by acting as cloud condensation or ice nuclei. In order to understand the implications of bioaerosols, measurement of ambient bioaerosols, as well as laboratory studies of bioaerosols, are necessary. Physical principles that are applied to collect non-biological aerosol particles can also be used to collect bioaerosols. Analysis of collected biological particles could be performed using a variety of techniques, such as culture, characterization of nucleic acids and proteins, as well as real-time methods using spectroscopy and mass spectrometry. However, it is essential that the properties of biological particles that allow their analysis and quantitation to be preserved during and after sampling, which often requires compromises in sampling efficiency. This tutorial will review the traditional and modern techniques for bioaerosol collection and real-time measurement. The advantages and disadvantages of various methods for sampling and detection, as well as their applications, will be discussed. Biological aerosols could be released into the ambient environment by various means, and laboratory generation of bioaerosols generally seeks to reproduce naturally generated bioaerosols through adaptation of similar physical mechanisms, e.g. using controlled liquid agitation to produce representative particles. This tutorial will also focus on describing the natural processes that generate bioaerosols and commonly used techniques to create similar bioaerosols in the laboratory setting.

Introduction to Aerosols 2: The Particle Size Distribution and Its Dynamics

Abstract: This tutorial continues the basic introduction to aerosol science. In this session we focus on developing the tools to describe the dynamics of aerosol populations. An aerosol is an ensemble of particles in a gas, and the particles are distributed over a range of sizes. Therefore, they must be represented by a particle size distribution. We will discuss the representation of aerosol populations as size distributions, their graphical representation, and models such as the log normal-distribution. Condensation and evaporation of volatile species onto particles determines their growth in the atmosphere, and efficient counting of particles too small to detect optically in condensation particle counters. Both continuum and non-continuum effects must again be considered, as must the surface tension which governs particle activation, initial activation, and the possibility of nucleating new particles from the vapor phase. These processes also alter the shape of the size distribution. Particle-particle collisions lead to coagulation, which further alters the size distribution. We will examine how these diverse processes are combined to describe the population dynamics for aerosol systems.

Sensor Data Science Bootcamp

Abstract: The recent proliferation of low-cost aerosol and gas sensors has sparked much interest among the scientific community. Such devices show promise to enable measurements at unprecedented spatial and temporal scales, which, in turn, can lead to the creation of distributed sensor networks to support both traditional research and community-based research. With these exciting prospects, however, come challenges of sensor performance, sensor reliability, and data management. This tutorial will review basic principles of statistics and data science for real-time aerosol sensors, with a focus on low-cost (<$2,000) devices. Topics to be covered will include data management and cleaning, exploratory data analysis, linear models, troubleshooting techniques (and potential solutions), statistical issues relevant to time-series data (such as autocorrelation), and determination of analytic figures of merit (e.g., accuracy, bias, prevision, limit of detection). Participants need not have formal training in data science beforehand; self-help resources for learning basic data science in the R and MATLAB programming languages will be provided.

Mixed methods (quantitative/qualitative) studies applied to household-level solid-fuel combustion in LMIC and Native Nations

Abstract: Understanding sources of air pollution is critical to effective air quality management. Air pollution composition in low- and middle- income countries (LMICs) and Native Nations is still not well characterized. In particular, household-level solid fuel combustion contributes substantially to poor air quality and air pollution exposures in urban, peri-urban, and rural settings. In this tutorial, we will discuss household-level solid fuel combustion and exposures to household air pollution in these communities. We will focus on the application of mixed methods for studying the diverse sources of air pollution in these locales and the strategies so far in place or in development for mitigating them.

Session 3: 1:00 PM - 2:40 PM


An Introduction to Reduced-Complexity Models for Air Quality

Abstract: Chemical transport models (CTMs) are the gold standard for predicting how changing emissions will influence future air quality. However, they are computationally intensive, meaning that only a limited number of scenarios can be simulated in detail. Furthermore, they require considerable expertise, limiting the communities of researchers that can assess how emissions changes will affect ambient concentrations of air pollutants and human health. Reduced-Complexity Models (RCMs) fill this gap by providing tools that are better suitable for screening and uncertainty analyses and useable by policy and energy systems analysts that lack resources and expertise to use CTMs.

This training will provide an introduction to three RCMs now publicly available for air quality assessments: APEEP, EASIUR, and InMAP. We will summarize the inner workings and assumptions in each of these models. We will demonstrate where to obtain these models, introduce how to use them, including how to adjust assumptions about dose-response and economic valuation. An intercomparison of the results of the models will be summarized.

Aerosol Thermodynamics

Abstract: This tutorial covers the fundamentals of aerosol thermodynamics and some of the tools available for aerosol thermodynamics calculations. Atmospheric particles are composed of water, inorganic electrolytes and organic compounds that may be water soluble or insoluble. These compounds interact in the particle phase to govern the gas-particle partitioning of semi-volatile compounds, the phase partitioning of these species within the particle phase, and the amount of water associated with the water soluble compounds in the particle. Fundamentally, aerosol thermodynamics differs from “normal” thermodynamics in that the independent variable is the relative humidity for ambient and laboratory aerosols whereas with “normal” thermodynamics the independent variable is usually the solute concentration.

The tutorial will be divided into two major topics. The first will cover the fundamentals of aerosol thermodynamics. The second will cover some of the on-line tools available to help with aerosol thermodynamics calculations.

Biological Endpoints: Which should I measure in relation to disease

Abstract: While the evidence linking short and long-term exposures to air pollutants is well established, there are still considerable gaps in our understanding of the underlying causal pathways, linking exposure to symptom exacerbation and disease development. This information is essential to provide a causal underpinning of the association observed in epidemiolocal studies. Therefore, the acute toxicological effects, usually quantified one day after particle delivery to the lungs, are not necessarily predictive for long-term effects leading to pulmonary tissue disorders or even development of chronic lung diseases. In vitro assays, however determining the persistent cytotoxicity of nanoparticles for pulmonary phagocytes might hold promise to evaluate or predict long-term toxicity. Attendees of this tutorial will be introduced to the best available biomarkers and scientific approaches/models to evaluate both the acute and long-term consequences of air pollution on health.

Nucleation of particles from the gas phase

Abstract: Nucleation of condensed-phase particles from the gas phase is of fundamental importance in contexts ranging from atmospheric aerosols, to nanoparticle formation in industrial process chambers, to formation of interstellar dust. Considering the ubiquitous importance of nucleation, it is remarkable that it remains poorly understood, in the sense that no fundamental theories exist that accurately predict, for virtually all substances, either the rate of nucleation or its dependence on conditions such as temperature and vapor saturation ratio. Therefore, nucleation represents a fundamental challenge and opportunity for the development of improved understanding. This tutorial reviews the classical theory of homogeneous nucleation, non-classical atomistic theory, steady-state and transient nucleation, and chemical nucleation, including nucleation in flames and plasmas, and discusses comparisons of theoretical predictions with experimental observations.
