Smog Alert Response

This guide to smog alert response begins with a section on the basics of an effective smog response program. It provides a rationale for program development, indicates the role of municipalities, outlines the development of a smog alert response plan, and notes related activities that can be implemented outside of the traditional smog season. Section 2 reviews how to expand the scope, influence, & impact of smog response programs through such initiatives as community outreach & education, partnerships, research, and linkages with other municipal priorities. Section 3 highlights examples of municipal actions across Ontario which may be of interest to those engaged in the process of smog alert response. Section 4 covers the science of smog, including smog constituents & their characteristics, smog precursors, the relationship of smog to geography and meteorology, and how smog is monitored & reported in Ontario. The final section presents a sample municipal operational plan and a resource kit for municipalities that includes sample policies, contracts, by-laws, newsletters, & promotional materials.

The world's cities are choking on pollution from traffic and industry. With the health of over 1.6 billion people under threat, poor urban air quality is fast becoming one of them most pressing environmental problems of our times. Smog Alert examines the causes and scale of urban air pollution, identifying who is most at risk, and what particular health risks various pollutants pose. It then considers an effective framework for air quality management, so that national and city authorities can consider what pollution control polices and measures are needed to deliver healthy urban air quality, and to sustain it in the future. Having established the background and framework, the book examines the existing and alternative measures to monitor and combat the declining air quality. It assesses smog alert systems; the potential for cleaner car and fuel technology; sustainable traffic management and public transport policies; and methods of controlling both industrial and residential emissions. Detailed case studies illustrate the severity and breadth of the problem - from the first serious photochemical smogs in Los Angeles to the dire warning offered by Mexico City; and from London (the city which coined the word 'smog') to Athens' pollution phenomenon, the 'nefos'. Drawing on the lessons learned from past experience, Smog Alert provides a comprehensive analysis of how health air quality may yet be achieved in the world's cities.

Ontario's Ministry of the Environment monitors, analyzes and forecasts ambient air quality. When unacceptably high levels of ground-level ozone are present or expected, the ministry issues official smog alerts. The 1st section of this guide outlines how municipalities can take effective action by putting local smog response programs in place. It includes information on developing a smog alert response policy, staff training, and maintaining awareness. The 2nd section contains useful information on air quality and smog, including the harmful effects of smog, its major sources and components, and the relationship between smog and the weather. A list of practical smog alert workplace actions in included.

The main objective of these updated global guidelines is to offer health-based air quality guideline levels, expressed as long-term or short-term concentrations for six key air pollutants: PM2.5, PM10, ozone, nitrogen dioxide, sulfur dioxide and carbon monoxide. In addition, the guidelines provide interim targets to guide reduction efforts of these pollutants, as well as good practice statements for the management of certain types of PM (i.e., black carbon/elemental carbon, ultrafine particles, particles originating from sand and duststorms). These guidelines are not legally binding standards; however, they provide WHO Member States with an evidence-informed tool, which they can use to inform legislation and policy. Ultimately, the goal of these guidelines is to help reduce levels of air pollutants in order to decrease the enormous health burden resulting from the exposure to air pollution worldwide.

This book presents WHO guidelines for the protection of public health from risks due to a number of chemicals commonly present in indoor air. The substances considered in this review, i.e. benzene, carbon monoxide, formaldehyde, naphthalene, nitrogen dioxide, polycyclic aromatic hydrocarbons (especially benzo[a]pyrene), radon, trichloroethylene and tetrachloroethylene, have indoor sources, are known in respect of their hazardousness to health and are often found indoors in concentrations of health concern. The guidelines are targeted at public health professionals involved in preventing health risks of environmental exposures, as well as specialists and authorities involved in the design and use of buildings, indoor materials and products. They provide a scientific basis for legally enforceable standards.

This paper assesses whether responses to information about risk impact estimates of the relationship between ozone and asthma in Southern California. Using a regression discontinuity design, I find smog alerts significantly reduces daily attendance at two major outdoor facilities. Using daily time-series regression models that include year-month and small area fixed effects, I find estimates of the effect of ozone for children and the elderly that include information are significantly larger than estimates that do not. These results are consistent with the hypothesis that individuals take substantial action to reduce exposure to risk; estimates ignoring these actions are severely biased.

This book explores various and distinct aspects of environmental health literacy (EHL) from the perspective of investigators working in this emerging field and their community partners in research. Chapters aim to distinguish EHL from health literacy and environmental health education in order to classify it as a unique field with its own purposes and outcomes. Contributions in this book represent the key aspects of communication, dissemination and implementation, and social scientific research related to environmental health sciences and the range of expertise and interest in EHL. Readers will learn about the conceptual framework and underlying philosophical tenets of EHL, and its relation to health literacy and communications research. Special attention is given to topics like dissemination and implementation of culturally relevant environmental risk messaging, and promotion of EHL through visual technologies. Authoritative entries by experts also focus on important approaches to advancing EHL through community-engaged research and by engaging teachers and students at an early age through developing innovative STEM curriculum. The significance of theater is highlighted by describing the use of an interactive theater experience as an approach that enables community residents to express themselves in non-verbal ways.
