“…For example, direct mortality sources (Loss et al, 2012) are not incorporated into our models. Direct mortality from collision (Bing et al, 2012;Low et al, 2017), poisoning from pesticides and pollutants (Kim et al, 2016;Barghi et al, 2018), and illegal trapping and consumption (Kamp et al, 2015;Yong et al, 2015) are reported in the region, and are possible cause of declines of these species. These sources of direct mortality, in addition to habitat loss and degradation from land-use change are still major threats on the breeding grounds in South Korea and non-breeding grounds.…”

Population declines in terrestrial bird species have been reported across temperate regions in the world and are attributed to habitat loss, climate change, or other direct mortality sources. North American and European studies indicate that long-distance migrants, common species, and species associated with grasslands and agricultural lands are declining at the greatest rates. However, data from East Asia on avian population trends and associated drivers are extremely sparse. We modeled changes in occupancy of 52 common breeding landbird species in South Korea between 1997–2005 and 2013–2019. Thirty-eight percent of the species showed evidence of declines, and seven of these were declining severely (46–95%). Occupancy of Black-capped Kingfisher (Halcyon pileata) populations have dropped the most precipitously over the study period. Among declining species, long-distance migrants (9/20) and common species (14/20) showed more rapid declines than other groups. Declines of five species were associated with climate change, and two species appeared to be affected by land-cover change. However, causes of change in occupancy of other species (46/52) remains cryptic. Based on our results, we suggest an immediate re-evaluation of species’ conservation status and legal protection levels for seven severely declining species in South Korea, and a dedicated survey design and analysis effort for the continued monitoring landbird populations. Because many species exhibiting declines migrate from beyond national boundaries, international collaborations will be required to better quantify population trends across the full annual cycle, and to understand mechanisms for these declines.

“…PFAS are persistent, pervasive contaminants that have been found on all continents and in the serum of many animals that have been studied [ 44 , 45 , 46 ]. They resist degradation while in the environment and require more sophisticated purification techniques to remove from water, once they have been introduced [ 25 , 47 , 48 ].…”

Large-scale manufacturing of poly- and perfluorinated compounds in the second half of the 20th century has led to their ubiquity in the environment, and their unique structure has made them persistent contaminants. A recent drinking water advisory level issued by the United States Environmental Protection Agency lowered the advisory level concentration of perfluorooctanesulfonic acid (PFOS) and perfluorooctanoic acid (PFOA) from 200 nanograms per liter and 400 nanograms per liter, respectively, to 70 nanograms per liter separately or combined. Small temporal variations in PFOS and PFOA concentrations could be the difference between meeting or exceeding the recommended limit. In this study, newly sampled data from a contaminated military site in Alaska and historical data from former Pease Air Force Base were collected. Data were evaluated to determine if monthly variations within PFOS and PFOA existed. No statistically significant temporal trend was observed in the Alaska data, while the results from Pease, although statistically significant, showed the spread of observed contaminant concentrations around the fitted line is broad (as indicated by the low R2 values), indicating that collection date has little value in predicting contaminant concentrations. Though not currently the subject of a US EPA health advisory, data on perfluorobutanesulfonic acid (PFBS), perfluorohexane sulfonic acid (PFHxS), perfluoroheptanoic acid (PFHpA), and perfluorononanoic acid (PFNA) were collected for each site and their average concentrations evaluated.

“…During the early phase of the pandemic in China, indiscriminate use of disinfectants had resulted in abnormal deaths of wild animals including wild boars, weasels, blackbirds and other birds (You 2020 ; Yingzi and Xiaomin 2020 ). Chlorine disinfectants are known to be toxic to aquatic and terrestrial organisms by causing cell damage (Sedlak and Gunten 2011 ) affecting respiratory and digestive systems (Bull et al 1990 ), giving rise to secondary carcinogenic chemicals (Marine et al, 2019 ) apart from exhibiting potential for bioaccumulation (Barghi et al 2018 ). The introduction, persistence and probable transfer of such toxic chemicals in the interconnected food webs of terrestrial and aquatic ecosystems raise grave concerns.…”

Graphical abstract The nexus of COVID-19 and environment is conspicuously deep-rooted. The roles of environmental factors in the origin, transmission and spread of COVID-19 and the mutual impact of the pandemic on the global environment have been the two perspectives to view this nexus. The present paper attempts to systematically review the existing literature to understand and explore the linkages of COVID-19 with environment and proposes conceptual frameworks to underline this nexus. Our study indicates a critical role of meteorological factors, ambient air pollutants and wastewater in severe acute respiratory syndrome coronavirus 2(SARS-CoV-2) transmission-spread dynamics. The study also focuses on the direct and indirect impacts of COVID-19 on the regional and global environment. Most of the indirect environmental effects of COVID-19 were attributed to global human confinement that resulted from the implementation of the pandemic containment measures. This worldwide anthropogenic ‘pause’ sent ripples to all environmental compartments and presented a unique test bed to identify anthropogenic impacts on the earth’s natural systems. The review further addresses emerging sustainability challenges in the new normal and their potential solutions. The situation warrants critical attention to the environment-COVID-19 nexus and innovative sustainable practices to address the ramifications of short- and long-term environmental impacts of the COVID-19 pandemic.
