Airports are identified hotspots for air pollution, notably for fine particles (PM) 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 and selected emitted co-pollutants (CO, NO, and O), 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 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 concentrations were as follows: Vancouver, 5.31 ± 0.017; Toronto, 6.71 ± 0.199; and Montreal, 7.52 ± 0.023 μg/m. The smallest and the coldest airport with the least flights/passengers had the highest PM 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 and submicron particles, including nanoparticles in residential areas close to airports was observed, conforming with the recommended workplace health thresholds (~ 2 × 10 cm), while before the lockdown, condensable particles were up to ~ 1 × 10 cm. Targeted reduction of PM emission is recommended for cold climate regions.

Acid mine drainage (AMD) is a worldwide problem that degrades river systems and is difficult and expensive to remediate. To protect affected catchments, it is vital to understand the behaviour of AMD-related metal(loid) contaminants as a function of space and time. To address this, the sources, loads and transport mechanisms of arsenic (As), copper (Cu), zinc (Zn), iron (Fe) and sulfur (S) in a representative AMD-affected catchment (the Carnon River in Cornwall, UK) were determined over a 12-month sampling period and with 22 years of monitoring data collected by the Environment Agency (England) (EA).

Untreated hyperprolactinemia and autoimmune thyroiditis (Hashimoto's disease) seem to increase cardiometabolic risk. The cardiometabolic effects of cabergoline were less significant in young women with concurrent euthyroid Hashimoto's illness. This study sought to investigate if the detrimental effects of this condition on cabergoline efficacy are also evident in postmenopausal women.

Low-lying and small tropical coral reef islands around the world are extremely vulnerable to the effects of global environmental change caused by the combination of anthropogenic climate change and escalating extreme hydrodynamic events. Erosion and inundation are anticipated to physically destabilize the tropical coral reef islands, rendering them uninhabitable within the next century. Therefore, it is crucial to assess the repercussions of these hazardous events on the delicate reef island ecosystem in order to conserve and ensure sustainable management.

This study aims to examine the landscape transformation and temperature dynamics using multiple spectral indices. The processes of temporal fluctuations in the land surface temperature is strongly related to the morphological features of the area in which the temperature is determined, and the given factors significantly affect the thermal properties of the surface. This research is being conducted in Pakistan to identify the vegetation cover, water bodies, impervious surfaces, and land surface temperature using decadal remote sensing data with four intervals during 1993-2023 in the Mardan division, Khyber Pakhtunkhwa.
