AER’s new dickhead Laurie Pushor off to Kenney-wanna-be-Trump races: “No Duty of Care” AER abuses Covid-19 crisis to deregulate oilpatch and foothills coal mining. (Stephen Cousin’s sketch may offend some, but it’s too perfect not to add to this vulgar news.)
Broomfield Colorado: To learn the true abusive nature of the frac beast & judicial industry enabling the beast, read this: Sheltering frac’d at home from Coronavirus has families frightened for their lives. Rightly so with published research showing air pollution dramatically increases Covid-19 fatalities, never mind living frac’d with an “evacution plan in chaos.”
Are Covid-19 fatalities a measure of the oil & gas industry’s killing power? More and more studies prove how deadly & dishonest the industry is. Message to CAPP & AER: It’s not “odours” killing us, it’s pollution, including nitrogen dioxide.
Rule-of-law-when-it-suits-them: Trump order this for his pals to stretch their selfish greedy pockets even more while escalating pollution that’s already risking the lungs & lives of millions? Covid-19 can be brutal on healthy lungs, never mind lungs poisoned by fossil fuels.
Role of the chronic air pollution levels in the Covid-19 outbreak risk in Italy by Daniele Fattorini and Francesco Regoli, September 2020, Environmental Pollution, Vol 264
• Covid-19 outbreak in Italy is exhibiting a clear regional trend.
•Long-term air-quality data correlate with Covid-19 in the Italian provinces.
•Chronic atmospheric pollution may favour coronavirus spreading.
•Environmental pollution should be considered in epidemics prevention.
After the initial outbreak in China, the diffusion in Italy of SARS-CoV-2 is exhibiting a clear regional trend with more elevated frequency and severity of cases in Northern areas. Among multiple factors possibly involved in such geographical differences, a role has been hypothesized for atmospheric pollution. We provide additional evidence on the possible influence of air quality, particularly in terms of chronicity of exposure on the spread viral infection in Italian regions. Actual data on Covid-19 outbreak in Italian provinces and corresponding long-term air quality evaluations, were obtained from Italian and European agencies, elaborated and tested for possible interactions.
Our elaborations reveal that, beside concentrations, the chronicity of exposure may influence the anomalous variability of SARS-CoV-2 in Italy. Data on distribution of atmospheric pollutants (NO2, O3, PM2.5 and PM10) in Italian regions during the last 4 years, days exceeding regulatory limits, and years of the last decade (2010–2019) in which the limits have been exceeded for at least 35 days, highlight that Northern Italy has been constantly exposed to chronic air pollution.
Long-term air-quality data significantly correlated with cases of Covid-19 in up to 71 Italian provinces (updated April 27, 2020) providing further evidence that chronic exposure to atmospheric contamination may represent a favourable context for the spread of the virus.
Pro-inflammatory responses and high incidence of respiratory and cardiac affections are well known, while the capability of this coronavirus to bind particulate matters remains to be established. Atmospheric and environmental pollution should be considered as part of an integrated approach for sustainable development, human health protection and prevention of epidemic spreads but in a long-term and chronic perspective, since adoption of mitigation actions during a viral outbreak could be of limited utility.
Covid-19 Atmospheric pollution Chronic exposure Viral diffusion Italy
In December 2019, several pneumonia cases were suddenly observed in the metropolitan city of Wuhan (China), as the result of infection to a novel coronavirus (Li et al., 2020; Wu et al., 2020; Xu et al., 2020). This virus was termed SARS-CoV-2 for its similarity with that responsible of the global epidemic Severe Acute Respiratory Syndrome (SARS) occurred between 2002 and 2003 (Xu et al., 2020). Patients affected by SARS-CoV-2 infection often experienced serious complications, including organ failure, septic shock, pulmonary oedema, severe pneumonia and acute respiratory stress syndrome which in several cases were fatal (Chen et al., 2020; Sohrabi et al., 2020). The most severe symptoms, requiring intensive care recovery, were generally observed in older individuals with previous comorbidities, such as cardiovascular, endocrine, digestive and respiratory diseases (Sohrabi et al., 2020; Wang et al., 2020a). The World Health Organization (WHO) has defined this new syndrome with the acronym Covid-19 for Corona Virus Disease 2019 (Sohrabi et al., 2020; WHO, 2020a).
The drastic containment measures adopted by Chinese government did not prevent the diffusion of SARS-CoV-2, which in a few weeks has spread globally. Italy was the first country in Europe to be affected by the epidemic Covid-19, with an outbreak even larger than that originally observed in China (Fanelli and Piazza, 2020; Remuzzi and Remuzzi, 2020). Other European countries and United States rapidly registered an exponential growth of clinical cases, leading to restrictions and a global lockdown with evident social and economic repercussions (Cohen and Kupferschmidt, 2020; ECDC, 2020). The WHO has recently declared the pandemic state of Covid-19 with over 2.8 million of cases reported and over 201.000 victims worldwide (Cucinotta and Vanelli, 2020; WHO, 2020b; ECDC, 2020, accessed on April 27, 2020).
The ongoing epidemic trend in Italy immediately showed strong regional differences in the spread of infections, with most cases concentrated in the north of the country (Remuzzi and Remuzzi, 2020). The distribution of positive cases reported from February 24th to April 27th is summarized in Fig. 1A: some areas of Lombardy and Piedmont clearly exceeded 10.000 cases, e.g. 18.371 at Milan, 12.564 at Brescia, 11.113 at Bergamo, 12.199 at Turin (data re-elaborated from the official daily reports of the Department of Civil Protection,ICPD, 2020, accessed on April 27, 2020). Also, the relative percentage distribution of the positive test rate (Fig. 1B) exhibit higher values in Northern Italy despite a certain uncertainty of data due to the different numbers and frequency of oropharyngeal swabs performed in various regions to test coronavirus positivity; mortality rate ranged from 18% in the northern regions to less than 5% in the others (Fig. 1C). Overall these trends closely parallel the rates of reported Covid-19 cases and of fatal events, expressed as percentage values normalized to the number of inhabitants for regional populations (Fig. 1D and E), further evidencing a significantly greater diffusion in Northern Italy, both in terms of number of infections and the severity of cases (mortality).
To explain such geographical trend, it was initially assumed that restrictions decided by government authorities after the first outbreak in Lombardy, had contained the infection preventing its rapid spread to the rest of the country. Some authors, however, from the clinical course of a large cohort of patients, have concluded that the epidemic coronavirus had been circulating in Italy for several weeks before the first recognized outbreak and the relative adopted containment measures (Cereda et al., 2020). In this respect, the differentiated occurrence of infection cannot be fully explained by the social confinement actions.
Since the presence of comorbidities appeared determinant for the aetiology and severity of the Covid-19 symptoms (Chen et al., 2020; Wang et al., 2020b; Wu et al., 2020), the role of atmospheric pollution in contributing to the high levels of SARS-CoV-2 lethality in Northern Italy has been hypothesized (Conticini et al., 2020).
Association between short-term exposure to air pollution and Covid-19 infection has been described also for the recent outbreak in China (Zhu et al., 2020). The adverse effects of air pollutants on human health are widely recognized in scientific literature, depending on various susceptibility factors such as age, nutritional status and predisposing conditions (Kampa and Castanas, 2008).
Chronic exposure to the atmospheric pollution contributes to increased hospitalizations and mortality, primarily affecting cardiovascular and respiratory systems, causing various diseases and pathologies including cancer (Brunekreef and Holgate, 2002; Kampa and Castanas, 2008). Among air pollutants, the current focus is mainly given on nitrogen dioxide (NO2), particulate matter (PM2.5 and PM10) and ozone (O3), frequently occurring at elevated concentrations in large areas of the planet.
The percentage of European population exposed to levels higher than the regulatory limits is about 7–8% for NO2, 6–8% for PM2.5, 13–19% for PM10 and 12–29% for O3 (EEA, 2019). Premature deaths due to acute respiratory diseases from such pollutants are estimated to be over to two million per year worldwide and 45.000 for Italy (Brunekreef and Holgate, 2002; Huang et al., 2016; EAA, 2019; Watts et al., 2019).
Here, we are providing additional evidence on the possible influence of air quality on the spread of SARS-CoV-2 in Italian regions. Since the effects of air pollutants on human health not only depend on their concentrations but also, if not especially, on chronicity of exposure, we have elaborated the last four years (from 2016 to 2019, EEA, 2020) of regional distribution of NO2, PM2.5 and PM10 as presented in Fig. 2. The highest atmospheric concentrations were clearly distributed in the Northern areas (Piedmont, Lombardy, Veneto and Emilia-Romagna), in addition to urbanized cities, such as Rome and Naples.
The long-term condition of population exposure is also revealed by the number of days per year in which the regulatory limits of O3 and PM10 are exceeded (Fig. 3A–B): the critical situation of Northern Italy is reflected by values of up to 80 days of exceedance per year (average of the last three years, EAA, 2019).
Worthy to remind, ozone is one of the main precursors for the formation of NO2, and chronic exposure to this contaminant for almost a quarter of a year is undoubtedly of primary importance.
The chronic air pollution in Northern Italy is further represented by the number of years during the last decade (2010–2019) in which the limit value for PM10 (50 μg/m3 per day) has been exceeded for at least 35 days (Fig. 3C). Once again, these data would provide evidence that the whole Northern area below the Alpine arc has been constantly exposed to significantly higher levels of these contaminants.
The hypothesis that atmospheric pollution may influence the SARS-CoV-2 outbreak in Italy was also tested from the relationships between the confirmed cases of Covid-19 in up to 71 Italian provinces (updated April 27, 2020) with the corresponding air quality data. The latter were expressed as average concentrations in the last 4 years of NO2, PM2.5 and PM10 (Fig. 4A–C) and the number of days exceeding the regulatory limits (averages of the last 3 years) for O3 and PM10 (Fig. 4D–E). The always significant correlations provided further evidence on the role that chronic exposure to atmospheric contamination may have as a favourable context for the spread and virulence of the SARS-CoV-2 within a population subjected to a higher incidence of respiratory and cardiac affections.
It is well known that exposure to atmospheric contaminants modulate the host’s inflammatory response leading to an overexpression of inflammatory cytokines and chemokines (Gouda et al., 2018). Clear effects of Milan winter PM2.5 were observed on elevated production of interleukin IL-6 and IL-8 in human bronchial cells (Longhin et al., 2018), and also NO2 was shown to correlate with IL-6 levels on inflammatory status (Perret et al., 2017). The impairment of respiratory system and chronic disease by air pollution can thus facilitate viral infection in lower tracts (Shinya et al., 2006; van Riel et al., 2006).
In addition, various studies have reported a direct relationship between the spread and contagion capacity of some viruses with the atmospheric levels and mobility of air pollutants (Ciencewicki and Jaspers, 2007; Sedlmaier et al., 2009). The avian influenza virus (H5N1) could be transported across long distances by fine dust during Asian storms (Chen et al., 2010), and atmospheric levels of PM2.5, PM10, carbon monoxide, NO2 and sulphur dioxide were shown to influence the diffusion of the human respiratory syncytial virus in children (Ye et al., 2016), and the daily spread of the measles virus in China (Chen et al., 2017; Peng et al., 2020).
Although the capability of this coronavirus to bind particulate matters remains to be established, chronic exposure to atmospheric contamination and related diseases may represent a risk factor in determining the severity of Covid-19 syndrome and the high incidence of fatal events (Chen et al., 2020; Conticini et al., 2020; Dutheil et al., 2020; Wang et al., 2020a; Wu et al., 2020).
In conclusion, the actual pandemic event is demonstrating that infectious diseases represent one of the key challenges for human society.
Our findings, if confirmed by future studies, suggest that air quality should also be considered as part of an integrated approach toward sustainable development, human health protection and prevention of epidemic spreads. However, the role of atmospheric pollution should be considered in a long-term, chronic perspective, and adoption of mitigation actions only during a viral outbreak could be of limited utility. We need to highlight that our analyses did not include other important determinants of Covid-19 incidence and mortality, such as age structure, lifestyle factors (e.g. diet or smoking habits), the prevalence of pre-existing conditions such as cardiovascular and respiratory problems and diabetes prior to the pandemic, the capacity of the healthcare system, the case identification practices (e.g. the percentage of the population that were tested and the percentage of positive tests to the total number of tests), and the duration of the confinement, among others. Given these limitations, our findings should be interpreted as more hypothesis-generating rather than confirmatory. As such, we call for future studies to fill this gap of knowledge by addressing at which extent the aforementioned factors may have mutually contributed to the diffusion of Covid-19 in Italy.
