“…BC surface concentration levels are especially influenced by winds, precipitation, planetary boundary layer, as well as atmospheric mixing heights due to sensitivity to wet and dry deposition [ 17 – 20 ]. Studies have also demonstrated that the effects from air pollution events can persist on a scale of days to months with impacts on atmospheric chemistry, weather, biogeochemical cycles, and linkage to disease and premature death [ 21 – 26 ]. However, monitoring pollutant impacts can be limited by uncertainty and discrepancies between air pollution datasets [ 27 – 28 ].…”

Air pollution is one of the major environmental concerns in Vietnam. In this study, we assess the current status of air pollution over Hanoi, Vietnam using multiple different satellite datasets and weather information, and assess the potential to capture rice residue burning emissions with satellite data in a cloud-covered region. We used a timeseries of Ozone Monitoring Instrument (OMI) Ultraviolet Aerosol Index (UVAI) satellite data to characterize absorbing aerosols related to biomass burning. We also tested a timeseries of 3-hourly MERRA-2 reanalysis Black Carbon (BC) concentration data for 5 years from 2012–2016 and explored pollution trends over time. We then used MODIS active fires, and synoptic wind patterns to attribute variability in Hanoi pollution to different sources. Because Hanoi is within the Red River Delta where rice residue burning is prominent, we explored trends to see if the residue burning signal is evident in the UVAI or BC data. Further, as the region experiences monsoon-influenced rainfall patterns, we adjusted the BC data based on daily rainfall amounts. Results indicated forest biomass burning from Northwest Vietnam and Laos impacts Hanoi air quality during the peak UVAI months of March and April. Whereas, during local rice residue burning months of June and October, no increase in UVAI is observed, with slight BC increase in October only. During the peak BC months of December and January, wind patterns indicated pollutant transport from southern China megacity areas. Results also indicated severe pollution episodes during December 2013 and January 2014. We observed significantly higher BC concentrations during nighttime than daytime with peaks generally between 2130 and 0030 local time. Our results highlight the need for better air pollution monitoring systems to capture episodic pollution events and their surface-level impacts, such as rice residue burning in cloud-prone regions in general and Hanoi, Vietnam in particular.

“…Air pollutants such as particulate matter (Sanderfoot & Holloway, ) and CO 2 (Paoletti, De Marco, Beddows, Harrison, & Manning, ) are typically higher in urban than in rural areas, and the levels of surface ozone in the lower atmosphere have increased at a higher rate in urban compared to rural areas since 1990 (Paoletti et al, ). These and other air pollutants impose respiratory constraints, and increase detoxification efforts and stress levels on birds (reviewed in Sanderfoot & Holloway, ), which increase their oxygen uptake 10–20 times when in flight (Maina, ). Air pollution can influence bird flight behaviour.…”

“…Migrating birds might modify flight altitudes in response to the air pollution of urban areas. Research about the effects of air pollution in the environment and in birds, however, has focused mostly on terrestrial and aquatic habitats (reviewed in Lovett et al, ), and on on‐the‐ground specimens (reviewed in Sanderfoot & Holloway, ), research is needed to evaluate its effects on airspace habitat use (Diehl, Peterson, Bolus, & Johnson, ) and bird behaviour aloft (but see Li et al, ).…”

1. Urban areas affect terrestrial ecological processes and local weather, but we know little about their effect on aerial ecological processes.2. Here, we identify urban from non-urban areas based on the intensity of artificial light at night (ALAN) in the landscape, and, along with weather covariates, evaluate the effect of urbanization on flight altitudes of nocturnally migrating birds.3. Birds are attracted to ALAN; hence, we predicted that altitudes would be lower over urban than over non-urban areas. However, other factors associated with urbanization may also affect flight altitudes. For example, surface temperature and terrain roughness are higher in urban areas, increasing air turbulence and height of the boundary layer, and affecting local winds. 4. We used data from nine weather surveillance radars in the eastern United States to estimate altitudes at five quantiles of the vertical distribution of birds migrating at night over urban and non-urban areas during five consecutive spring and autumn migration seasons. We fit Generalized Linear Mixed Models by season for each of the five quantiles of bird flight altitude and their differences between urban and non-urban areas.5. After controlling for other environmental variables and contrary to our prediction, we found that birds generally fly higher over urban areas compared to rural areas in spring, and marginally higher at the mid-layers of the vertical distribution in autumn. We also identified a small interaction effect between urbanization and crosswind speed, and between urbanization and surface air temperature, on flight altitudes. We also found that the difference in flight altitudes of nocturnally migrating birds between urban and non-urban areas varied among radars and seasons, but was consistently higher over urban areas throughout the years sampled. 6. Our results suggest that the effects of urbanization on wildlife extend into the aerosphere and are complex, stressing the need of understanding the influence of anthropogenic factors on airspace habitat.

“…Studies have been conducted on the effects of PM containing neocotinoid insecticides on economically important insects such as honey bees, these insecticides are widely used in seed coating and it has been shown that bees are exposed to these substances during seed sowing with lethal effects compatible with the colony losses observed by beekeepers (Tapparo et al 2012). In the city, PM is abundant and from diverse origin, its impact on urban insect health is possible but remain a study to carry out, so far there are some reports about air PM effects on dogs (Calderón-Garcidueñas et al 2017) and avian species health (Sanderfoot and Holloway 2017). Insects and their health can serve as biological indicators for indirectly monitor air quality, since as reported by Negri et al 2015 and by the present work, insects accumulate in one way or another both PM and large agglomerates.…”

This study was made to assess airborne dust by sampling particles trapped in car air filters (CAFs) of Mexico City. The CAFs dust was analyzed by optical microscopy and SEM-EDX. The optical microscopy revealed that the dust contains organic matter; insect and plant debris and inorganic matter; quartz sand, plastics and polystyrene. This material was classified in different sizes (from 10 µm to 76 µm). Particulate matter (PM) trapped within the filter fiber arrangements were observed by SEM-EDX. PM of Mexico City was characterized as mainly agglomerated particles and fine particles. Agglomerates were mechanically disintegrated and main components were determined finding elements such as C, O, Si, Al, Ca and Fe. An impaction test was implemented to have insights into how agglomerates probably hit the filter surface, disintegrate and reintegrate other agglomerates. Pollen particles were frequently associated with agglomerated PM; its composition was analyzed, finding Pt on its surface among others. Likewise, the insect debris presented plenty of PM adhered to its surface. This work validates that CAFs are a simple, cheap and adequate sampling approach for further urban air quality evaluations.
