Honey, let me tell you about this city! Honey as a biomonitor for lead distribution in urban environments Description: A look at city, regional, and global-scale applications of honey as a record for lead distribution in the environment. Lead isotopes in honey elucidate source-apportionment and distribution of Pb in a range of urban settings: from very young cities (e.g., Vancouver, BC) to cities with millennia-scale history of lead use (Paris, France), and this approach is applicable in both chronic/diffuse pollution settings and after acute lead pollution events. |

Gary Mallach Air Effects Scientist Health Canada |
In-vehicle air filtration and acute changes in cardiopulmonary and cognitive function among healthy adults. Description: We measured commuters’ exposure to air pollutants in rush-hour traffic and evaluated whether this exposure could be reduced by cabin air filtration. Also, we looked at effects on cardiopulmonary health, as well as cognition (mental processing and judgement), examining whether cabin air filtration reduced exposure to traffic related air pollutants and improved short term cardiopulmonary and cognitive function. Results will provide information about air pollution’s effects on cognition, an area of growing concern, while testing a potentially valuable and economical means of reducing exposure to traffic related air pollution in a commuting environment. |

Effects of work injury and RTW on family of precariously employed workers The impact of work injury and the return to work process on family members of injured workers has often been characterized in the context of standard than precarious jobs. Drawing on 19 in-depth interviews with precariously employed workers and employers, we identified three areas where workers’ compensation policy and employer processes did not fit well with the situations of precarious workers in Ontario. Consequently responsibility fell on family members to provide instrumental and financial support while |

Understanding Defensive Health Behavior: Evidence from Pollution Masks in Delhi. Air pollution in Delhi, India is among the highest in the world, but few residents choose to self-protect using particulate filtering masks. In this project, results were documented from two field experiments designed to understand the factors influencing mask use. In the first, differences in income levels and experimental variation in information, experience with masks, and perception of social norms were found to affect respondents' likelihood to purchase masks, but demand remained low relative to other highly polluted cities. The second intervention took advantage of a public intervention of unprecedented scale: the Delhi municipal government distributed 5 million masks during the 2018/2019 pollution season. Mask effectiveness and social acceptance beliefs did not seem to change in this intervention. |

Trevor Peckham PHD Student, Department of Environmental and Occupational Health Sciences at the University of Washington |
Precarious Employment and Health in the United States The dramatic changes in the organization of work over the last several decades—including the general shift toward more flexible and competitive employment practices—have not been adequately examined from a public health perspective. To do so, traditional models of work and health research need to be expanded beyond a sole focus on work tasks or physical and social environments to include the relational and contractual aspects of employment that may also impact health. Here we examine the association between the multidimensional construct of employment quality (EQ)—defined as the terms and conditions of the employment relationship, such as contract type, wage/benefit levels, and employee representation—and workers’ health in two nationally representative U.S. surveys. Using cross-sectional data from the General Social Survey and a latent class analysis measurement approach, we identify eight disparate patterns of EQ. |

Health and the built environment: Looking to the future Just over 50% of the global population is urbanized, with cities expected to absorb all future population growth. In general, urban populations are healthier, with improved access to services and healthcare. Densely populated cities also play a key role in efforts to reduce emissions related to global warming. Yet, cities face significant challenges, especially those in the rapidly developing megacities of low and middle income countries. Urban design and management and the ways that we interact with this “built environment” can profoundly impact health. Air pollution, noise, mobility options and land-use, among others, play a role and interact in multiple, complex ways. Understanding these interactions and using this knowledge to shape our cities as they grow has the potential improve population health and build resilience to climate change. In this presentation I will review a number of analyses using cohorts and linked administrative data combined with geospatial estimates of environmental exposure to examine built environment-health linkages, describe emerging trends, and discuss implications for population health |

Anxiety, Access and Trust: Communicating with new mothers about infant vaccination Information use in vaccination decision-making has evolved with the movement toward patient activation coupled with the arrival of online and social content sharing. Effective risk communication requires understanding the information seeking, assessment and use of specific vaccine-hesitant populations. This study applied ethnographic research methods to identified communities of low vaccine uptake in order to improve public health communication with new mothers at risk for vaccine hesitancy. |

Urban natural spaces and public health: a matter of challenges or common sense? Over the last decade, research on human health impacts of urban natural spaces has rapidly developed. An increasing number of epidemiological studies demonstrates direct and indirect health benefits by exposure to urban green and blue spaces. While these studies have significantly contributed to confirming associations between nature exposure and various health outcomes, a number of challenges remain before evidence on mechanisms and causality can be established. These challenges range from uncertainty about optimal exposure measures to what physiological effects can be expected from nature contact. Nevertheless, the side effects of “urban green interventions” occur limited. By taking also co-benefits, such as increased biodiversity and climate change mitigation from urban natural spaces, into account there seems to be little to lose from a policy perspective by advocating for more natural spaces in our cities, although the evidence is still insufficient. This presentation will provide an outline of the current evidence level and present research challenges in on-going studies around urban nature and human health. It will also discuss the prevailing discourse around pathways and mechanisms. Finally, the goal is to initiate a debate around opportunities and risks with taking a “nothing-to-lose” approach to urban green initiatives across the world. |

Mar 27 | Hugh Davies | Advancing surveillance protocols for antineoplastic drug exposures in health care settings
Abstract: The number of people receiving antineoplastic drug treatment for cancer is increasing as the population ages and more people are diagnosed with cancer. While these drugs are powerful tools in the fight against cancer exposure to these drugs can also cause genetic damage miscarriages and cancer in otherwise healthy people. Despite the dissemination of safe handling practices, healthcare workers and others such as veterinarians continue to be exposed through surface contamination. Guidelines such as USP Chapter 800 call for routine workplace surveillance but do not provide detailed guidance on how this should be done or how to interpret surface wipe samples. The SURveillance For AntiCancer drugs Exposure Study (SurFACES) sampled up to 20 different surfaces monthly at nine facilities in the US and Canada for one year, and obtained 2000 samples, each tested for 11 antineoplastic drugs. In this presentation we will characterize exposures found at the sites, discuss spatial and temporal patterns and determinants of exposures, and discuss how the findings can be used to provide improved AD surveillance guidance to practitioners. |

Assessing Sub-Daily Exposure to Wildfire Smoke and its Public Health Effects in British Columbia Inhaling smoke emitted by wildfires can affect human health. This is a growing concern for public health as wildfires will occur more frequently and affect more communities under the changing climate. This research aimed to improve our ability to monitor wildfire smoke exposures every hour at different locations in British Columbia during wildfire seasons, and to study whether more people call the ambulance during hours with more smoke. The findings show that ambulance calls for heart and lung conditions increased within one hour of exposure to smoke, while calls for diabetic conditions increased after 24 hours. These results suggest that the health effects from wildfire smoke can occur soon after exposure, and actions to reduce exposure should be taken promptly. |

Determining causation and creating an exposure history for long latency occupational disease claims – challenges and practical tools Despite studies showing that occupational exposures are responsible for approximately 2 to 10 percent of all newly diagnosed cancer cases, many cancers are not recognized as being work-related and consequently not filed with the workers’ compensation system. This presentation will provide an overview of the challenges and potential solutions in better establishing evidence of exposure that not only shows medical causation, but also meets the test of legal causation. It will discuss the role of epidemiology in determining a general causal link between a disease and an occupational exposure as well as the need to build a comprehensive occupational history to answer the question of whether an individual work developed the disease as a result of their job. |

Anxiety and Depression disorders among workers with Musculoskeletal injury in British Columbia Anxiety and depression are leading causes of global disability and frequently co-occur with physical health conditions. The purpose of this research was to describe the occurrence of anxiety and depression disorders among workers with musculoskeletal work injury in British Columbia, and to investigate the impacts of these disorders on work disability outcomes. Approximately 1 in 10 men and 3 in 10 women were found to have a recent or current anxiety or depression disorder at the time of musculoskeletal work injury, and both pre-existing and new onset anxiety and depression disorders were associated with longer work disability. Collectively these results support the inclusion of anxiety and depression disorders as part of the disability management plan for workers with musculoskeletal work injury. |

Quantifying the burden of disease from major sources of ambient fine particulate matter: Insights from an atmospheric chemist Air pollution, specifically fine particulate matter (PM2.5) in outdoor air, is recognized by the Global Burden of Disease (GBD) as the leading environmental risk factor for human health, attributable to 7.5% of all deaths in 2016. To reduce exposure to ambient PM2.5, contributions from major emission sources must be quantified. Previous studies have identified coal and residential emissions as dominant sources in polluted regions in Asia and fossil fuel emissions as dominant global sources. These studies, however, have been limited to particular regions or have focused on large, aggregate emission sectors. Here, we expand upon previous work and utilize recent updates to anthropogenic emission inventories and atmospheric chemical transport modeling to quantify the source- and fuel-specific PM2.5 exposure levels for all 195 countries and territories currently included in the GBD. This presentation will focus on methods used to quantify PM2.5 exposure levels and discuss ongoing collaborations to quantify the burden of disease from all major sources. |

Where Matters: The Health and Economic Impacts of Where We Live There is a public health crisis happening right now. Total health expenditure in Canada was estimated to be up to $253.5 billion ($6,839 per person) for 2018. This represents 11% of Canada’s gross domestic product according to the Canadian Institute for Health Information. For example, obesity, high blood pressure, and diabetes place tremendous pressure on our healthcare system. There is an increasing consensus that the postal code of the neighbourhood where we live is as important as our genetic code. Studies have shown that land-use decisions and transportation investments to enhance neighborhood walkability and access to green space can significantly affect how you travel and your physical activity, and exposure to air pollution, traffic safety and crime, and noise. Very few studies have examined how transportation investment, neighbourhood walkability and access to green space are associated with less chronic disease and lower health care cost. To date, existing evidence used to inform major transportation investment decisions have rarely accounted for the potential health impacts and related costs of these factors. The Where Matters Study aims to incorporate health into local and regional policy-making by examining the multiple pathways linking the way our communities are planned and designed with people’s travel and physical activity patterns, chronic disease risk and health care cost. |

The PURE Air Study: A multinational examination of household air pollution concentrations & primary fuel switching determinants
Approximately 2.5 billion individuals (~40% of global population), primarily in rural areas of Asia (>1.5 billion), Sub-Saharan Africa (>500 million) and Latin America (>50 million) are exposed to harmful household air pollution (HAP) from cooking and heating with polluting fuels (e.g. wood, crop waste, animal dung, coal) in rudimentary stoves. Exposure to HAP was the second highest environmental risk factor in the Global Burden of Disease (GBD) 2017, with an estimated 1.6 million attributable deaths annually. Residential combustion of polluting fuels is also a major contributor to outdoor air pollution and emissions of climate-forcing agents, including up to one-third of global anthropogenic emissions of black carbon. Few multinational studies have examined multilevel (e.g. household, community, national) factors associated with households switching from polluting to clean (gas, electric) primary cooking fuels. Longitudinal epidemiological studies of HAP exposure are also sparse due to the financial and time intensity associated with such studies. The Prospective Urban and Rural Epidemiology (PURE)-Air study, one of the largest HAP exposure assessments to-date, was carried out among rural communities of eight countries: Bangladesh, Chile, China, Colombia, India, Pakistan, Tanzania and Zimbabwe. The study design enabled an examination of physical, environmental and contextual determinants of primary cooking fuel switching and household air pollution concentrations. The concentrations measured in the PURE-Air study will be used in one of the largest epidemiological analyses of cardiovascular and respiratory disease burden due to cooking and heating with polluting fuels. |

A closer look at energy expenditure and pollution inhalation during urban cycling: Physics, physiology, and travel behaviour Although urban cycling is widely known and promoted as physically active transportation, the actual physics of utilitarian cycling have been given little attention in transportation engineering and planning. In contrast, the field of sports science has developed detailed data and models of road bicycle performance, but only for sport and racing cyclists. What can we learn about utilitarian cycling by integrating knowledge of the physical attributes of bicycles and cyclists? Findings will be presented from recent and ongoing studies aiming to quantify these relationships and enhance travel analysis tools with an understanding of the physical aspects of cycling. |

Can a single strand of hair be used to monitor exposure to toxic metals? Hair is a growing keratinous tissue comprised of sulfur. As such, the sulfur in the hair can bind the many elements present in circulating blood, including toxic metals. Since hair is metabolically inert once formed, the elements retained in the tissue become locked in, so as the hair grows it can record changes in blood element concentrations over time. Using laser ablation on single strands of hair, exposure histories can be revealed for toxic metals. But, there are some caveats, including external contamination by air, water, and hair treatments. Here we will discuss occupational exposure to lead and other metals, compare hair and blood concentrations, effects of contamination on hair concentrations, examine another growing keratinous tissue (nails) for metal monitoring, and provide forensic case studies from an inadvertent poisoning event, and the historic Franklin Expedition. |
