“…Recent longitudinal studies have found that long-term exposure to ambient pollution is associated with reduced lung growth in children (8)(9)(10). These findings are supported by animal models, which have found that chronic exposure to particulate pollution impairs lung development (11,12).…”

Rationale: Few studies have examined associations between exposure to air pollution and childhood lung function after implementation of strict air quality regulations in the 1990s.Objectives: To assess traffic-related pollution exposure and childhood lung function.Methods: We geocoded addresses for 614 mother-child pairs enrolled during pregnancy in the Boston area 1999-2002 and followed them until a mid-childhood visit (median age, 7.7). We calculated the proximity of the home to the nearest major roadway. We estimated first year of life, lifetime, and prior-year exposure to particulate matter with a diameter smaller than 2.5 mm (PM 2.5 ) by a hybrid model using satellite-derived aerosol optical depth, and to black carbon (BC) by a land-use regression model. Measurements and Main Results:Residential proximity to roadway and prior-year and lifetime PM 2.5 and BC exposure were all associated with lower FVC. Associations with FEV 1 were also negative and proportionally similar. Pollution exposures were not associated with the FEV 1 /FVC ratio or bronchodilator response. Compared with distances greater than or equal to 400 m, living less than 100 m from a major roadway was associated with lower FVC (298.6 ml; 2176.3 to 221.0). Each 2 mg/m 3 increment in prior-year PM 2.5 was associated with lower FVC (221.8 ml; 243.9 to 0.2) and higher odds of FEV 1 less than 80% predicted (1.41; 1.03-1.93). Each 0.2 mg/m 3 increment in prior-year BC was associated with a 38.9 ml (270.4 to 27.3) lower FVC.Conclusions: Estimates of long-term exposure to ambient pollution, including proximity to major roadway, PM 2.5 , and BC (a traffic-related PM 2.5 constituent), were associated with lower lung function in this Boston-area cohort of children with relatively low pollution exposures.

“…Longo and Yang [ 52 ] and Iwasawa et al [ 8 ] reported a higher risk of acute bronchitis across the lifespan in humans exposed to sulfurous volcanic air pollution. Furthermore, in 2013, Camarinho et al [ 22 ] showed that noneruptive active volcanism is associated with increased lung injury in mice. Thus, it is not unexpected to observe an increase in the exacerbation of COPD severity in the population living in Ribeira Quente, a volcanic area with elevated soil diffuse degassing.…”

“…Previous studies evidenced that Furnas inhabitants have a high incidence of chronic bronchitis and of some cancer types (e.g., lip, oral cavity, and pharynx) [ 19 , 20 ] and a higher risk of DNA damage in human buccal epithelial cells [ 21 ]. Moreover, a very recent study by Camarinho et al [ 22 ] showed that chronic exposure to volcanogenic air pollutants causes lung injury in wild mice. However, to our knowledge, up to date no study was carried out to assess the association between volcanogenic air pollution by soil diffuse degassing (DDS) and the risk of development of respiratory defects.…”

The aim of this study was to assess whether chronic exposure to volcanogenic air pollution by hydrothermal soil diffuse degassing is associated with respiratory defects in humans. This study was carried in the archipelago of the Azores, an area with active volcanism located in the Atlantic Ocean where Eurasian, African, and American lithospheric plates meet. A cross-sectional study was performed on a study group of 146 individuals inhabiting an area where volcanic activity is marked by active fumarolic fields and soil degassing (hydrothermal area) and a reference group of 359 individuals inhabiting an area without these secondary manifestations of volcanism (nonhydrothermal area). Odds ratio (OR) and 95% confidence intervals (CIs) were adjusted for age, gender, fatigue, asthma, and smoking. The OR for restrictive defects and for exacerbation of obstructive defects (COPD) in the hydrothermal area was 4.4 (95% CI 1.78–10.69) and 3.2 (95% CI 1.82–5.58), respectively. Increased prevalence of restrictions and all COPD severity ranks (mild, moderate, and severe) was observed in the population from the hydrothermal area. These findings may assist health officials in advising and keeping up with these populations to prevent and minimize the risk of respiratory diseases.

“…Studies in mice exposed to volcanic emissions have provided evidence of increased alveolar damage (decrease in alveolar space and perimeter, increase in alveolar septal thickness, inflammation and particle deposits) compared to mice exposed to environmental pollutants [49]. Inflammatory lung reactions were noted in lymph nodes after 13 weeks of exposure to volcanic ash, and the reaction lasted until 49 weeks after exposure [50].…”

Volcanoes form along the edges of tectonic plates. Although it is true that volcanic eruptions are destructive, these eruptions also have benefits. Volcanic eruptions provide minerals to the surrounding soil, and these minerals are beneficial to agriculture and can be used as building materials. Exposure to volcanic emissions can threaten the health of inhabitants in many ways; dermal and ocular irritation, cardiopulmonary exacerbations in people who suffer from chronic diseases, and even cancer have been linked with exposure to volcanic emissions. When rainwater passes through volcanic ashes deposited on land surfaces, the leaching of metals leads to significant changes in the chemistry of the surface water, increasing the risk of drinking water and land contamination. In addition to the health effects, volcanic eruptions are known to lead to surface cooling at the regional and global scales because of the emission of fine ash particles; however, these emissions, being a source of sulfates, contribute to acid rain formation. Because volcanic ash is highly abrasive, this ash can lower visibility and cause considerable damage to the engines of transportation systems. To avoid fatalities, it is important to closely monitor volcanic activity and promote a culture of prevention at all levels of society.
