Give me a sample of air and I will tell which species are found from your region : Molecular identification of fungi from airborne spore samples
2017
Fungi are a megadiverse group of organisms, they play major roles in ecosystem functioning and are important for human health, food production and nature conservation. Our knowledge on fungal diversity and fungal ecology is however still very limited, in part because surveying and identifying fungi is time demanding and requires expert knowledge. We present a method that allows anyone to generate a list of fungal species likely to occur in a region of interest, with minimal effort and without requiring taxonomical expertise. The method consists of using a cyclone sampler to acquire fungal spores directly from the air to an Eppendorf tube, and applying DNA barcoding with probabilistic specie…
Unconventional Reducing Gases Monitoring in Everyday Places
2017
Abstract Air pollution, be it indoors or outdoors, is a major environmental health concern as it can lead to serious health effects, such as respiratory diseases, including asthma and lung cancer. Much progress has been made in Europe in improving outdoor air quality and limit values have been set for several pollutants. However, indoor air quality also requires attention because this is where we spend most of our time. Measurements at appropriate spatial and temporal scales are essential for understanding and monitoring heterogeneous environments with complex and highly variable emission sources, such as in urban areas. However, the costs and complexity of conventional air quality measurem…
Global, regional, and national comparative risk assessment of 79 behavioural, environmental and occupational, and metabolic risks or clusters of risk…
2015
Summary Background The Global Burden of Disease, Injuries, and Risk Factor study 2013 (GBD 2013) is the first of a series of annual updates of the GBD. Risk factor quantification, particularly of modifiable risk factors, can help to identify emerging threats to population health and opportunities for prevention. The GBD 2013 provides a timely opportunity to update the comparative risk assessment with new data for exposure, relative risks, and evidence on the appropriate counterfactual risk distribution. Methods Attributable deaths, years of life lost, years lived with disability, and disability-adjusted life-years (DALYs) have been estimated for 79 risks or clusters of risks using the GBD 2…
ENVIRONMENTAL EFFECTS ON FRACTIONAL EXHALED NITRIC OXIDE IN ALLERGIC CHILDREN
2011
Fractional exhaled nitric oxide (FeNO) is a non-invasive marker of airway inflammation in asthma and respiratory allergy. Environmental factors, especially indoor and outdoor air quality, may play an important role in triggering acute exacerbations of respiratory symptoms. The authors have reviewed the literature reporting effects of outdoor and indoor pollutants on FeNO in children. Although the findings are not consistent, urban and industrial pollution—mainly particles (PM2.5 and PM10), nitrogen dioxide (NO2), and sulfur dioxide (SO2)—as well as formaldehyde and electric baseboard heating have been shown to increase FeNO, whilst ozone (O3) tends to decrease it. Among children exposed to …
Spunti critici sull’aggiornamento della normativa europea in tema di qualità dell’aria
2022
This paper aims at presenting an argument in favour of the need for a prompt update of the European legislation on air quality, by taking its cue from the current situation in Italy. The paper starts by providing a definition of outdoor air pollution and by referring to the most influential Italian scientific studies on the main health risks connected. The perspective then shifts to the analysis of the relevant legislation at both European and national level in an attempt to systematically recompose the complex framework of plans and regulations adopted for the containment and prevention of outdoor pollution. In this framework, the analysis of the three infringement procedures opened agains…
Inquinamento ambientale, fumo e asma grave
2018
The health burden of air pollution on the world’s children is immense. Environmental factors are responsible for an estimated 26% of all children’s death worldwide. A large body of research exists on the effects of air pollution on children’s health, including effects on fetal growth, birth outcomes, lung development and function, asthma, respiratory infection and otitis media. It is also clearly linked to a higher risk of developing asthma, a major cause of morbidity in children. Indoor environments contribute significantly to total human exposure to air pollutants. Overall, people spend most time indoors. Pollutants remain in the air longer inside than outside. Some pollutants may be two …
