Effects of persistent organic pollutants on environment, health and mountains: a review

Journal of Environmental Engineering and Science, 2023
Persistent organic pollutants (POPs) are chemicals that persists in environment, bio-accumulate through the food chain and can exhibit toxic effects with threatening effects to environment, humans and animals. Due to their volatility and semi-volatility,

[The effect of high altitude on human color perception].

Sheng li xue bao : [Acta physiologica Sinica], 2020
Exposure to a high altitude hypoxia environment has significant negative effects on human central nervous system. Many previous studies have explored the influence of the high altitude environment on human color perception in a simulated high altitude environment or in an environment acutely exposed to high altitude, but little has been done in ...

Effect of hypoxia on human cognitive ability and indoor oxygen environment demand for sojourners at high altitude

Building and Environment, 2021
Abstract The hypoxic environment on mountain plateaus exerts a significant negative impact on human cognitive ability and physiological well-being. Although progress has been made in the study of the cognitive decline of sojourners exposed to hypoxic environments, further knowledge that establishes the proper indoor oxygen environment beneficial for ...

Effect of 2 Hours' Exposure to Simulated High Altitude (4,500 m) on Human Red Cell Metabolism

Scandinavian Journal of Clinical and Laboratory Investigation, 1972
During acute exposure to high altitude (2 hours) the red cell metabolism is altered. A pH-induced increase in phosphofructokinase activity together with a decrease in the level of the monophosphoglycerates are the most prominent features of the changes. Despite the increase in pH, the level of 2,3-diphos-phoglycerate is not altered, probably because of

[Effect of high altitude hypoxia on the human EEG].

Zhurnal vysshei nervnoi deiatelnosti imeni I P Pavlova, 1980
The paper presents the results of the comparative study of the EEG at alpine altitudes (Tuya -- Ashu pass, 3200 m) and at low altitudes (City of Frunze, 760 m above the sea level). The dynamics of EEG changes at different stages of adaptation to hypoxia is also traced.

[Effects of hyperbaric oxygen preconditioning on human stress responses during acute exposure to high altitude].

Zhonghua lao dong wei sheng zhi ye bing za zhi = Zhonghua laodong weisheng zhiyebing zazhi = Chinese journal of industrial hygiene and occupational diseases, 2016
To explore the effects of hyperbaric oxygen preconditioning (HBOP) on human stress responses during acute exposure to high altitude and the possible mechanism.Eight male subjects were treated with HBOP for 3, 5, and 7 days, followed by acute exposure to hypoxia simulating an altitude of 4,000 m.

Effect of high altitude on human auditory brainstem responses.

Indian journal of physiology and pharmacology, 2005
The effect of hypobaric hypoxia on Brain Stem Auditory evoked potentials (BAERs) were studied. BAERs were recorded in 30 volunteers at sea level (SL) and then at high altitude (HA) of 3200 m (HA I) and 4300 m (HA II) in Eastern Himalayas and on return to sea level (RSL).

The effect of high altitude on the protein composition of human blood

Bulletin of Experimental Biology and Medicine, 1961
Twelve healthy young individuals had the protein composition of their blood determined in Stalinabad (850 m) and during their sojourn in the mountain of East Pamir between the months of May and October, 1958, at the altitude of 4200 m.

Comparative studies of the effect of moderate and high altitude stress on human subjects: studies on erythrocyte ghost ATPases

International Journal of Environmental Studies, 1983
Studies have been carried out on erythrocyte membrane‐bound ATPases of ten female subjects at a moderate altitude (2200 m) and at a high altitude (5100 m). Mg2+‐ATPase activity of the subjects was found to be significantly stimulated under conditions at a high altitude in comparison to that at a moderate altitude.
