“…Based on these records, the average levels of SO 2 concentration in the island were recently published, and it was observed that the threshold recommended as safe by the European Commission was exceeded in the Valle area during 1 to 4% of the eruption duration. Furthermore, during the first month of the eruption, the threshold of 400 μm-3 was frequently exceeded, especially in the later stages of the phenomenon, in contrast to the emissions of particulate matter [ 2 , 26 ].…”

Background The eruption of the Tajogaite volcano began on the island of La Palma on September 19, 2021, lasting for 85 days. This study aims to present the design and methodology of the ISVOLCAN (Health Impact on the Population of La Palma due to the Volcanic Eruption) cohort, as well as the preliminary findings from the first 1002 enrolled participants. Methods A prospective cohort study was conducted with random selection of adult participants from the general population, with an estimated sample size of 2600 individuals. The results of the first 857 participants are presented, along with a group of 145 voluntary participants who served as interveners during the eruption. Data on epidemiology and volcano exposure were collected, and participants underwent physical examinations, including anthropometry, blood pressure measurement, spirometry, and venous blood extraction for toxicological assessment. Results In the general population (n = 857), descriptive analysis revealed that the participants were mostly middle-aged individuals (50.8 ± 16.4), with a predominance of females. Before the eruption, the participants resided at a median distance of 6.7 km from the volcano in the Western region and 10.9 km in the Eastern region. Approximately 15.4% of the sample required evacuation, whose 34.8% returning to their homes on average after 3 months. A significant number of participants reported engaging in daily tasks involving cleaning of volcanic ash both indoors and outdoors. The most reported acute symptoms included ocular irritation, insomnia, mood disorders (anxiety-depression), and respiratory symptoms. Multivariate analysis results show that participants in the western region had a higher likelihood of lower respiratory tract symptoms (OR 1.99; 95% CI:1.33–2.99), depression and anxiety (OR 1.95; 95% CI:1.30–2.93), and insomnia (OR 2.03; 95% CI:1.33–3.09), compared to those in the eastern region. Conclusion The ongoing follow-up of the ISVOLCAN cohort will provide valuable insights into the short, medium, and long-term health impact related to the material emitted during the Tajogaite eruption, based on the level of exposure suffered by the affected population.

“…In addition, nearby events can rapidly affect the air quality in less industrialized and poor cities. An example is the eruption of the Cumbre Vieja volcano, in the Canary Islands, which affected air quality in several cities in the Saharan region (Filonchyk et al, 2022).…”

“…Therefore, La Palma is the treated unit in our empirical setting. According to the extant literature, the volcanic eruptions have a negative impact on ecosystems near the volcano, with detrimental effects on the vegetation cover, quality of lands and therefore the quality of living of animals (Filonchyk et al, 2022). During the eruption period, a large column of smoke and ashes (mostly S02) moved to the atmosphere and towards the Iberian Peninsula, potentially affecting the nearby islands of La Gomera and Tenerife.…”
