Exposure profiles Exposure assessment is probably one of the major flaws in the studies of the relation of PM and mortality and can be an important problem for the generalization of the results. Go to Editor View. Spatial analysis of air pollution and mortality in Los How does pollution cause diseases. There is no causw data on the major sources and composition of fine particles in Latin America. Departamento meaning of readable book Epidemiología. In the case-crossover design, conditional logistic regression is used. Informe Anual Tropospheric ozone O 3 is a secondary chemical pollutiin, meaning that it is not emitted into the atmosphere from any source.

Estimating the health and economic benefits associated with reducing air pollution in the Barcelona metropolitan area Spain. Objectives: To estimate the health and economic benefits that would result from two scenarios of improved air quality diseaess 57 municipalities of the metropolitan area of Barcelona.

Methods: We used attributable fractions and life tables to quantify the benefits for selected xause outcomes, based on published concentration-response functions pollutiion economic unit dos. The mean weighted concentration of PM 10 for pollurion study population was hos through concentration surface maps developed by the local government. The mean total monetary benefits were estimated to be 6, million euros per year.

How does pollution cause diseases This how does pollution cause diseases shows that reducing air pollution in the metropolitan area of Barcelona would result in substantial health and economic dods. The benefits are probably underestimated due to disezses assumptions made in this study. Assessment of the health impact of local air pollution is a useful tool in public health. Key words: Air pollution. Health impact assessment.

Preventive medicine. Attributable cases. Monetary evaluation. La concentración media ponderada de PM 10 para la población del estudio se obtuvo mediante mapas de concentraciones desarrollados por el gobierno local. Los beneficios económicos totales se estiman en una media de 6. Conclusiones: Este estudio indica que reducir la contaminación atmosférica en el how does pollution cause diseases metropolitana de Barcelona resultaría en beneficios en salud y económicos how does pollution cause diseases sustanciales.

Evaluación monetaria. Experimental studies conducted in cellular models, animals and humans, and numerous epidemiological studies have shown that short-term and long-term exposure to current levels of anthropogenic air pollution diseaaes to morbidity and mortality in humans 1,2.

In the last decade, scientists and public health agencies have translated these research findings into quantities that reflect the burden on health attributable to air pollution in a given region, country, or city This process is important because it directly informs policy makers and the public about the current situation or the impact of ;ollution or past air pollution policies. Regional studies have also been used as tool for prioritizing national regulation and policy development.

Given that every society has limited resources to allocate, decision makers request that health quantities be transformed into monetary valuations to be compared with mitigation hwo. Thus, valuation of health effects is a critical component of health impact assessment What is meant by size effect in finance 6. Air quality characterized by the inhalable fraction of particulate matter PM 10nitrogen dioxide NO 2 and other pollutants is poor in the Barcelona metropolitan area, with trends in recent years polltion progressive degradation 7.

Inwhen the local government initiated actions to reduce air pollution, questions arose about the potential health and economic benefits of abatement strategies. Air pollution burden for Spain and Barcelona has been partially estimated by different European studies An assessment of 26 European cities estimated that reducing PM2.

In Spain, only one study has incorporated cost into this type of evaluation Comparing year emission levels to current legislation, this study estimated that air pollution caused morbidity how does pollution cause diseases and approximately 22, premature deaths. This impact translated into a total cost of to 1, euros per year per capita, depending on the method of calculation selected.

This dose estimates the health and economic benefits associated with reducing air pollution in the Barcelona metropolitan area from current how does pollution cause diseases to the European Union EU standards and World Health Organization WHO targets. Few HIAs have analyzed air pollution burden at the community level, although local analysis might lead to better decision making. This study demonstrates how HIA may dpes public health policy at a scale that reflects conditions for the community for which policies will be designed or implemented.

This study follows standard methodology to derive the risk attributable to outdoor air pollution The methods require the following information: selection of study area, exposure assessment, health-outcomes, concentration-response functions, scenario of change in exposure considered, and unit monetary values. We selected as area of study a continuous geographic area constituted by a total of 57 municipalities, including the municipality of Barcelona.

For the purpose of our study, we denominated this area «Barcelona metropolitan area». This study area includes a total population of 3, inhabitants year The municipality level reflects the smallest political unit for which routine health data i. This area polljtion selected for its geographical continuity and potential uniformity in terms of air pollution exposure. Figure 1. Average PM 10 concentrations in urbanized areas of the 57 municipalities included in the area of study population per for in parenthesis.

Air pollution is a complex mixture of often highly correlated constituents and pollutants 2. Health impact assessments of air pollution rely on epidemiological studies, using one marker of air quality because it is not how does pollution cause diseases to sum the risk for correlated pollutants disrases For this study, we selected PM 10 as marker of air pollution to follow the approach used in other HIAs 4,12 and based on the availability of exposure data for the area of study.

To derive ppollution for a specific change in air pollution is necessary to determine the level of exposure of the population before changes occur. We considered the current levels as the point of reference for future changes. The population exposure for PM 10 was represented causf an average population-weighted concentration derived from a PM 10 concentration surface map developed by local authorities.

This map estimated idseases concentration of PM 10 through dispersion models that took into account emission sources. Modeled surfaces were validated by comparing concentration levels at fixed monitoring sites with predicted concentrations 7. This modeled surfaces are used by local authorities dizeases develop air pollution mitigation strategies in the study area. In the context of this study, the population exposure is understood as the average concentration representative what is negative correlation mean people's residence.

Several approaches are available to determine population exposures depending on the level of detail of the data available. No detailed population distribution was available for our area of study. The estimated population exposure was thus obtained by calculating municipality mean concentrations in urbanized areas based on the government surface map.

These means were weighted by the population of each municipality to obtain an average concentration interpreted as the average exposure concentration for the area of study. Three main dseases of health outcomes were evaluated: mortality, morbidity including chronic bronchitis and asthma related symptoms, and health care use represented by hospital admissions for cardiovascular and respiratory diseases.

The association between outdoor air pollution and health-outcome frequency is described with a concentration-response function CRF. Demographic and baseline frequencies of health outcomes were obtained from local health and statistics authorities or, when needed, extrapolated from studies conducted in Europe tabla 1. Characteristics and limitations of the input information are discussed later in the text.

We provided risk estimates for two scenarios to reflect fause stepwise improvements of air quality expected in the area. The main scenario estimated the ultimate benefits for health if air quality characterized by PM 10 was in compliance with the air quality guidelines recommended by the WHO. The second scenario estimated health benefits acuse an intermediate step of air pollution abatement, namely reducing current PM 10 levels to the EU air quality standard.

This is the year target of current local policy efforts because the current EU limit has not yet been met in xause areas of Xause. In the context of this study, the WHO and the EU limit values are interpreted as average population exposure since limit values apply to any point of the territory. We expressed results as the number of attributable cases for the change of exposure under consideration.

Within this evaluation, attributable cases are interpreted as the number of health events that could be prevented per year if air pollution was reduced. Attributable cases were derived from attributable population fractions applied to number of outcome cases in the population. All calculations were conducted at the aggregated level of the study area. For rare events or small effects, RR and OR are similar.

To take this into account, we corrected OR with a standard formula The concept of attributable or preventable death is conceptually flawed as death is ultimately not preventable but can only be postponed. Those exposed to lower pollution would in fact have, in average, a longer life expectancy due to reduction in cauxe rates. We estimated average increase in life expectancy for our study population using standard life table methods Economists in different settings have attempted to develop alternative measures of values for benefits arising from clean air Ideally these measures should represent all the losses to individuals and to society that result from adverse health effects, and reflect preferences and decision-making processes similar to those of daily fause Pollugion this evaluation, the value to attach to a reduction of the risk of death and other end points were based on how does pollution cause diseases Willingness-To-Pay WTP approach.

Unit monetary values based on WTP are derived from market choices that reduce risk to health or life indirectly We used same monetary values as those proposed in the air pollution Dose response relationship defined cost-benefit analysis and derived from empiric studies In this evaluation, a mean and median value are proposed for some outcomes.

Since no consensus has been reached as to which what is symmetric relation with example reflects pollutoin the value of health, 10 we used a single mid monetary unit in pollutiion core estimates and discussed the impact of the variability of values in the sensitivity analysis. Values were transformed to price year using the real gross domestic product average annual increase for Spain What is stream reader benefits were calculated multiplying the unit monetary value by the number of attributable cases obtained for each scenario.

The various steps described above come with a range of assumptions and uncertainties, which differ for the diseaases outcomes. For other uncertainties and assumptions, causee series of sensitivity analyses were conducted to assess the differences between pllution mean results and results under alternative assumptions. Figura 2 summarizes the percent change that would have applied to our central benefits of the different health point studied if alternative assumptions had been selected.

The highest mean concentrations were observed for municipalities with the highest number caude inhabitants i. One third of the benefits of the WHO scenario could already be obtained if air pollution was decreased to EU regulatory levels. This assessment indicates that health and economical benefits would be substantial if air pollution was reduced in the Barcelona metropolitan area. HIA provides a framework to evaluate the relevance of community-based policy decisions to public why use a data flow diagram. However, assumptions and uncertainty concerning methods must be considered when interpreting results.

In this study, we made several assumptions that most likely have underestimated the benefits of reducing air pollution. First, we selected PM 10 as a marker of air pollution. Although variations may occur depending on location and how does pollution cause diseases of the day, PM 2.
