In 2015, 5.9 million children under age five died (1). The major causes of child deaths globally are pneumonia, prematurity, intrapartum-related complications, neonatal sepsis, congenital anomalies, diarrhoea, injuries and malaria (2). Most of these diseases and conditions are at least partially cau...sed by the environment. It was estimated in 2012 that 26% of childhood deaths and 25% of the total disease burden in children under five could be prevented through the reduction of environmental risks such as air pollution, unsafe water, sanitation and inadequate hygiene or chemicals.

En 2015, 5,9 millions d'enfants de moins de cinq ans sont décédés (1). Les principales causes de mortalité infantile dans le monde sont la pneumonie, la prématurité, les complications durant l'accouchement, la septicémie néonatale, les anomalies congénitales, la diarrhée, les tra...umatismes accidentels et le paludisme (2). La plupart de ces maladies et de ces problèmes sont, du moins en partie, causés par l'environnement. On a estimé en 2012 que 26 % des décès infantiles et 25 % de la charge totale de morbidité des enfants de moins de cinq ans pourraient être évités par la réduction des risques environnement aux tels que la pollution de l'air, l'insalubrité de l'eau, les mauvaises conditions d'hygiène et d'assainissement ou les produits chimiques.

This guideline covers road-traffic-related air pollution and its links to ill health. It aims to improve air quality and so prevent a range of health conditions and deaths.
Cardiovascular disease, diabetes, chronic obstructive pulmonary disease, cancers, and other non-communicable diseases are among the leading causes of morbidity and mortality in low-income, middle-income, and high-income countries, and The Lancet Taskforce recently made the case for investing in non-...communicable disease prevention. Now, in The Lancet Planetary Health, Benjamin Bowe and colleagues report that exposure to PM2·5 air pollution is indeed a risk factor for diabetes.

Economics plays a vital role in health policy-making and investments to reduce air pollution; in helping to understand the costs of health care; and in determining nations’ wealth and ability to invest in health and well-being..
Air pollution is one of the world’s leading killers. Globally, air pollution causes some 7 million deaths annually from outdoor and household sources.
Ocean plastic pollution has reached crisis level: every minute, more than an entire garbage truck of plastic makes its way into the world’s oceans—roughly 11 million metric tons annually. While plastic waste presents an immediate threat to marine wildlife and ecosystems, this global challenge al...so has implications for major industries such as fishing and tourism, impacting the livelihoods of millions of people. The drivers and impacts of ocean plastic pollution also contribute to global challenges in food security, human health, and climate change.

This report describes the “Building health workers capacity on air pollution and health” pilot workshop held in Ghana in 2022 which aimed at testing the training material of the first WHO Air Pollution and Health Training toolkit (APHT) targeting health professionals. APHT aims at strengthening ...the knowledge of health workers on air pollution and health and to enable them to effectively communicate with patients and communities on how to reduce their risk, to advocate for population level interventions as well as to train other peers and colleagues using a train-the-trainer approach. This workshop report serves as a tool and example of a training that can be replicated and adapted to other contexts and settings based on country and regional priorities and needs.

All health workers would benefit from gaining knowledge and skills to protect individuals and communities from air pollution exposure. This course examines the main health impacts of air pollution and which roles health workers can play to protect and promote people’s health.
Air pollution is a familiar environmental health hazard. We know what we’re looking at when brown haze settles over a city, exhaust billows across a busy highway, or a plume rises from a smokestack. Some air pollution is not seen, but its pungent smell alerts you.
Indoor air pollution is one of the world's largest environmental problems – particularly for the poorest in the world, who often do not have access to clean fuels for cooking.The Global Burden of Disease is a major global study on the causes and risk factors for death and disease. The study estima...tes of the annual number of deaths attributed to a wide range of risk factors are shown here. This chart is shown for the global total but can be explored for any country or region using the "change country or region" toggle.

Although air pollution is well known to be harmful to the lung and airways, it can also damage most other organ systems of the body. It is estimated that about 500,000 lung cancer deaths and 1.6 million COPD deaths can be attributed to air pollution, but air pollution may also account for 19% of all... cardiovascular deaths and 21% of all stroke deaths. Air pollution has been linked to other malignancies, such as bladder cancer and childhood leukemia. Lung development in childhood is stymied with exposure to air pollutants, and poor lung development in children predicts lung impairment in adults. Air pollution is associated with reduced cognitive function and increased risk of dementia. Particulate matter in the air (particulate matter with an aerodynamic diameter < 2.5 μm) is associated with delayed psychomotor development and lower child intelligence. Studies link air pollution with diabetes mellitus prevalence, morbidity, and mortality. Pollution affects the immune system and is associated with allergic rhinitis, allergic sensitization, and autoimmunity. It is also associated with osteoporosis and bone fractures, conjunctivitis, dry eye disease, blepharitis, inflammatory bowel disease, increased intravascular coagulation, and decreased glomerular filtration rate. Atopic and urticarial skin disease, acne, and skin aging are linked to air pollution. Air pollution is controllable and, therefore, many of these adverse health effects can be prevented.

Air pollution is a major environmental risk factor and contributor to chronic, noncommunicable diseases (NCDs). However, most public health approaches to NCD prevention focus on behavioural and biomedical risk factors, rather than environmental risk factors such as air pollution. This article discus...ses the implications of such a focus. It then outlines the opportunities for those in public health and environmental science to work together across three key areas to address air pollution, NCDs and climate change: (a) acknowledging the shared drivers, including corporate determinants; (b) taking a ‘co-benefits’ approach to NCD prevention; and (c) expanding prevention research and evaluation methods through investing in systems thinking and intersectoral, cross-disciplinary collaborations.

There is increasing interest in understanding the role of air pollution as one of the greatest threats to human health worldwide. Nine of 10 individuals breathe air with polluted compounds that have a great impact on lung tissue. The nature of the relationship is complex, and new or updated data are... constantly being reported in the literature. The goal of our review was to summarize the most important air pollutants and their impact on the main respiratory diseases (chronic obstructive pulmonary disease, asthma, lung cancer, idiopathic pulmonary fibrosis, respiratory infections, bronchiectasis, tuberculosis) to reduce both short- and the long-term exposure consequences. We considered the most important air pollutants, including sulfur dioxide, nitrogen dioxide, carbon monoxide, volatile organic compounds, ozone, particulate matter and biomass smoke, and observed their impact on pulmonary pathologies. We focused on respiratory pathologies, because air pollution potentiates the increase in respiratory diseases, and the evidence that air pollutants have a detrimental effect is growing. It is imperative to constantly improve policy initiatives on air quality in both high- and low-income countries.

The article "Air Pollution: The Emergence of a Major Global Health Risk Factor" discusses the significant health impacts of air pollution, a leading risk factor for global mortality. It highlights the adverse effects of fine particulate matter (PM2.5) and tropospheric ozone, linking them to cardiova...scular and respiratory diseases, cancer, and reduced life expectancy. While high-income countries have reduced air pollution levels, low- and middle-income countries face rising pollution, contributing to 4.9 million deaths in 2017. The article emphasizes the need for research to understand pollution’s health effects, identify key sources, and evaluate the effectiveness of interventions to improve air quality globally.
