“…Cadmium is highly phytotoxic to plants [18,19]. This hypothesis regarding the risk of Cd to plant life in airport soils is also supported by Rao et al [21], who identified its high potential ecological risk indicating potential harm to plants in their study monitoring the contamination of airport soils.…”

“…Mander et al [68] related air transport to the increased Cd content in soils and plants in the vicinity of runways. Similarly, Ray et al [23] and Rao et al [21] linked airport soils to contamination by Cd. Cadmium is highly phytotoxic to plants [18,19].…”

“…The results may, however, be slightly affected (underestimated) by runway reconstruction in 2010, though it is difficult to assess the impact of the reconstruction on the soil quality. Rao et al [21], in their study, related air traffic to environmental contamination by Cd and Pb. Other elements (Cu, Cr, Ni, and Zn) were then associated with natural sources in that study.…”

“…Calijuri et al [69] reported that emitted pollutants can be carried by rainwater into the airport's drainage system and subsequently transported to more remote areas. Even though the soil is reported to be a good sink for monitoring of traffic pollution [21,33], the environment needs to be monitored comprehensively in the case of airports, and air or water pollution should be addressed on a larger scale. Particles released during aircraft movement enter the environment immediately close to the runways and, due to atmospheric deposition, can settle in the soils of airports [64].…”

Environmental Impact Assessment of Potentially Toxic Elements in Soils Near the Runway at the International Airport in Central Europe

The environmental impacts of air transport and air transportation systems have become increasingly important and are heavily debated. The aim of the study was to determine the degree of soil contamination by the potentially toxic elements (Cu, Ni, Pb, and Zn) in the vicinity of the airport runway and to evaluate whether airport traffic has had factual toxic effects on airport vegetation. The overall assessment of soil contamination by means of the Nemerow integrated pollution index indicated slight pollution; evaluation by the geoaccumulation index evinced moderate contamination by Zn and nonexistent to moderate contamination by Cu, Ni, and Pb. A significant difference between the take-off and landing sections of the runway was not statistically confirmed. The vegetation risk assessment by means of the potential ecological risk index (RI) showed the low ecological risk, while the phytotoxicity test revealed an inhibition of up to 33.7%, with a slight inhibition of 16.7% on average, and thus low toxic effects of airport traffic on airport vegetation. The results of the linear regression model between phytotoxicity and RI manifested no relation between the two. The outcomes from other studies suggest that the range of elements and the extent of contamination can be highly variable at different airports and frequently affected by car traffic. Therefore, further research on this issue is needed for the more precise determination of the elements emitted by air traffic at airports.

“…It is worth noting that such elements have been previously observed near airports (Pal et al 2020 ). Other studies of soils near airports have also revealed the presence of different metals and heavy metals and while the concentrations vary from study to study, all agree that the concentration of these species is elevated (Özkan et al 2017 ; Rao et al 2014 ; Ray et al 2012 ). Since the EDS analysis detection is not sufficient for ultra-trace analysis, we also performed a complementary QQQ-ICP-MS/MS analysis.…”

Airports are identified hotspots for air pollution, notably for fine particles (PM 2.5 ) that are pivotal in aerosol-cloud interaction processes of climate change and human health. We herein studied the field observation and statistical analysis of 10-year data of PM 2.5 and selected emitted co-pollutants (CO, NO x , and O 3 ), in the vicinity of three major Canadian airports, with moderate to cold climates. The decadal data analysis indicated that in colder climate airports, pollutants like PM 2.5 and CO accumulate disproportionally to their emissions in fall and winter, in comparison to airports in milder climates. Decadal daily averages and standard errors of PM 2.5 concentrations were as follows: Vancouver, 5.31 ± 0.017; Toronto, 6.71 ± 0.199; and Montreal, 7.52 ± 0.023 μg/m 3 . The smallest and the coldest airport with the least flights/passengers had the highest PM 2.5 concentration. QQQ-ICP-MS/MS and HR-S/TEM analysis of aerosols near Montreal Airport indicated a wide range of emerging contaminants (Cd, Mo, Co, As, Ni, Cr, and Pb) ranging from 0.90 to 622 μg/L, which were also observed in the atmosphere. During the lockdown, a pronounced decrease in the concentrations of PM 2.5 and submicron particles, including nanoparticles , in residential areas close to airports was observed, conforming with the recommended workplace health thresholds (~ 2 × 10 4 cm −3 ), while before the lockdown, condensable particles were up to ~ 1 × 10 5 cm −3 . Targeted reduction of PM 2.5 emission is recommended for cold climate regions.
