Compared to staying in the indoor home environment, the effects of short visits to outdoor urban environments on short-term psychological, physiological and cognitive responses were not studied previously. Aim To evaluate whether visits to different urban and ethnic environments, in comparison to staying in the home indoor environment, leads to short-term changes in psychological, physiological and cognitive responses and whether these responses are independent of ethnicity. Methods The participants, 20-35 year-old healthy women (N = 72, 48 Arab and 24 Jewish), started the experiment at their home and visited six different outdoor urban environments in predominantly ethnic Arab or Jewish cities, in Israel. First they visited intra-ethnic city and afterward inter-ethnic city environments. In each city they first visited an urban park and afterward, in a random order, a residential neighbing the visits did not explain the observed changes between the outdoor environments and home. Conclusions Visits to urban parks compared to staying in the home environment had beneficial short-term changes in psychological, physiological, and cognitive responses, regardless of ethnicity. The changes could not be attributed to the investigated mediators. Women should be encouraged to go outdoors and specifically visit parks to improve their psychological and physiological health.Intentional or accidental release of copper nanoparticles (Cu-NPs) from consumer products during manufacturing, use, and end-of-life management could pose health and ecological risks. This paper presents a detailed study on the role of water chemistry on the fate of uncoated and carbon-coated Cu-NPs dispersed in aqueous cetyltrimethylammonium bromide (CTAB) surfactant in the presence and absence of humic acids (HAs).
