The problems associated with air pollution and higher air temperatures in cities have been known for over a century, but so have the impacts of trees and forests on improving air quality and regulating air temperatures. Science has advanced our understanding on the various ways that trees affect...

This section contains 3 papers focusing on the state of research in the ecotoxicology of pesticides; past, present and future pollutant materials; and soil pollution and its consequences on the above-ground fauna.

Adaptation to a warmer world is a priority, especially in large urban centres where the population is concentrated and heat-related risks are compounded by the urban heat island. These cities are also interested in improving their air quality. This paper summarizes and discusses current knowledge...

The different ways of exposure to recalcitrant pollutants, such as PCBs, for humans are contaminated foodstuffs, the breathing of contaminated air in the vicinity of leaking or used electrical transformers, containing or contaminated with PCBs.

Air pollution affects pollen allergy in at least three ways: through its direct effects on human health, through changes in plant health, and through the direct alteration of the allergenic pollen grain. This literature review addresses the latter point: the chemical or biological effects of air ...

Citizen controversies around air quality measurements are frequent in some places and one of the explanations happens to be the significant discrepancies between feelings and air quality measurements. These controversies testify to the social and health issue linked to this question and the fact...
