“…As ambient air pollution levels might confound the association between temperature and mortality (Analitis et al, 2014; Cox et al, In press), we obtained data on ozone (O 3 , 8-h maximum values), particulate matter with diameter less than 10 μm (PM 10 , daily averages), and nitrogen dioxide (NO 2 , daily averages) from the Belgian Interregional Environment Agency. In Belgium, air pollution is measured by a dense network of automatic monitoring sites (average distance between the nearest measuring stations is 25 km), collecting real-time data on a half-hourly basis.…”

Extreme temperatures are associated with increased mortality among humans. Because similar epidemiologic studies in animals may add to the existing evidence, we investigated the association between ambient temperature and the risk of mortality among dairy cattle. We used data on 87,108 dairy cow deaths in Belgium from 2006 to 2009, and we combined a case-crossover design with distributed lag non-linear models. Province-specific results were combined in a multivariate metaanalysis. Relative to the estimated minimum mortality temperature of 15.4 °C (75th percentile), the pooled cumulative relative risks over lag 0-25 days were 1.26 (95% CI: 1.11, 1.42) for extreme cold (1st percentile, −3.5 °C), 1.35 (95% CI: 1.19, 1.54) for moderate cold (5th percentile, −0.3 °C), 1.09 (95% CI: 1.02, 1.17) for moderate heat (95th percentile, 19.7 °C), and 1.26 (95% CI: 1.08; 1.48) for extreme heat (99th percentile, 22.6 °C). The temporal pattern of the temperature-mortality association was similar to that observed in humans, i.e. acute effects of heat and delayed and prolonged effects of cold. Seasonal analyses suggested that most of the temperature-related mortality, including cold effects, occurred in the warm season. Our study reinforces the evidence on the plausibility of causal effects in humans.

“…From 1990 to 2015, the burden of disease due to airborne toxins increased: smoking remained the second leading cause, while ambient air pollution moved up to fifth (Cohen et al 2017). Cattle also suffer air pollution, with up to 3% increased mortality, 10 μg/m 3 of PM 10 and ozone (Cox et al 2016).…”

Global exposures to air pollution and cigarette smoke are novel in human evolutionary history and are associated with about 16 million premature deaths per year. We investigate the history of the human exposome for relationships between novel environmental toxins and genetic changes during human evolution in six phases. Phase I: With increased walking on savannas, early human ancestors inhaled crustal dust, fecal aerosols, and spores; carrion scavenging introduced new infectious pathogens. Phase II: Domestic fire exposed early Homo to novel toxins from smoke and cooking. Phases III and IV: Neolithic to preindustrial Homo sapiens incurred infectious pathogens from domestic animals and dense communities with limited sanitation. Phase V: Industrialization introduced novel toxins from fossil fuels, industrial chemicals, and tobacco at the same time infectious pathogens were diminishing. Thereby, pathogen-driven causes of mortality were replaced by chronic diseases driven by sterile inflammogens, exogenous and endogenous. Phase VI: Considers future health during global warming with increased air pollution and infections. We hypothesize that adaptation to some ancient toxins persists in genetic variations associated with inflammation and longevity.

“…Seasonal analyses suggested that both men and women CEVD were more vulnerable to air pollution in cold seasons (winter and spring), and It was more evident in the ERRs of O 3 . Some previous papers reported that O 3 could elevate the cardiovascular mortality only in warm seasons, but more recent studies (especially those carried out in east Asia) reported more robust associations in cold seasons [29,[39][40][41]. In this study, the seasonal variations could largely attribute to the cold climate in Shenyang City.…”

The gender-based differences in the vulnerability to ambient air pollution have not been widely explored. This study aimed to investigate vulnerability differences to the short-term effects of PM 2.5 , PM 10 and O 3 between cerebrovascular diseases (CEVD) deaths of men and women. The general additive models (GAMs) and distributed lag non-linear models (DLNMs) were adopted, and both single-pollutant and two-pollutant models were performed to analyze the associations between ambient air pollution and daily CEVD deaths. Both models indicated that O 3 was the most suspicious pollutant that could induce excess CEVD deaths, and women tended to be more vulnerable to O 3. These results were confirmed by seasonal analysis, in which we also found both genders were more vulnerable to O 3 in winter. The exposure-response relationships revealed that women were usually more vulnerable to ambient air pollution than men, and the exposure-response curves differed significantly between genders. Our findings suggested that more attention should be paid on the adverse effects of ambient O 3 , and the protection of women CEVD population against air pollution should be emphasized.

Ambient Air Pollution-related Mortality in Dairy Cattle

Abstract: Background-Despite insights for humans, short-term associations of air pollution with mortality to our knowledge have never been studied in animals. We investigated the association between ambient air pollution and risk of mortality in dairy cows and effect modification by season.
