ULTRAVIOLET RADIATION AND GROUND‐LEVEL OZONE VARIATION IN LITHUANIA

Stratospheric ozone depletion, ultraviolet radiation and health

To our forebears the sky was the realm of the gods, inaccessible to mere humans. Only 100 years ago, the few scientists studying environmental problems would have been incredulous at suggestions that, by the late twentieth century, humankind would have begun to change the composition and function of the stratosphere. Yet this has happened. After 8000 generations of Homo sapiens, this generation...

Environment and health: 3. Ozone depletion and ultraviolet radiation.

Geostatistical Analysis and Mapping of Groundlevel Ozone in a Medium Sized Urban Area

Ground-level tropospheric ozone is one of the air pollutants of most concern. It is mainly produced by photochemical processes involving nitrogen oxides and volatile organic compounds in the lower parts of the atmosphere. Ozone levels become particularly high in regions close to high ozone precursor emissions and during summer, when stagnant meteorological conditions with high insolation and hi...

: metadiscourse in introduction sections of applied linguistics and physics research articles: exploring variation in frequency and type

abstract in written mode of language, metadiscourse markers are used commonly to help writers in general and academic writers in particular to produce coherent and professional texts. the purpose of the present study was to compare introduction sections of applied linguistics and physics articles regarding their use of interactive and interactional metadiscourse markers based on the model pro...

Simulated stratospheric ozone depletion and increased ultraviolet radiation: effects on photocarcinogenesis in hairless mice.

Solar ultraviolet radiation at the surface of the earth is a recognized cause of skin cancer. Postulated anthropogenic reductions in the thickness of the ozone layer would lead to an increased amount of ultraviolet radiation and hence would be expected to increase the risk of skin carcinogenesis. This study uses hairless (Skh:HR) mice as an animal model to study this increased risk. The mice we...
