Photochemical Oxidation of Soil Organic Matter by Sunlight
Although soils are considered as major carbon stores, rapid oxidation of soil organic carbon can contribute to CO2 evolution and global warming on a large scale. Generally, microbial and climatic factors are thought to be mainly responsible for such oxidative losses. Another probable factor is photodegradation by sunlight. Cultivated soils of the tropics are left barren for a greater part of th...
متن کاملEffects of photochemical smog
Photochemical smog IS a complex m1xture of chemiCals, some harmless. others h1ghly react1ve and poten11ally dangerous for plants, an1mats and humans. The main consmuents of photochemical smog are ozone (0.,) and nitrogen diox1de (N0 2). Although ozone is widely cons1dered the chTef indicator of photochemical smog, Ollrogen diox1de IS an important pollutant in 11s own right, alfecllng human and ...
متن کاملEffects of cloud overlap in photochemical models
[1] Different schemes have been used to represent the vertical coherence of clouds for radiation and cloud microphysics in general circulation models and for photolysis in photochemical transport models. Here, we examine the maximum-random overlap scheme, the random overlap scheme, and a linear scheme (linear scaling of the cloud optical depth in a grid box with cloud fraction) and evaluate the...
متن کاملThe Effects of Sunlight on Blood Pressure and Plasma Concentration of Na+,K+,T3,T4 B.
ABSTRACT: The exposure to light affects the biological functions of human.This Study has investigated the effects of duration of sunlight exposure on blood pressure and plasma concentration of Na+,K+,T3, T4 The subjects are two groups of workers from a construction company in Kerman . The first group (experimental )having an average of 8 Workhours in Sunshine (n=84) and the Second one (contro...
متن کاملPhotochemical Isotope Effects in the Early
There is increasing consensus on the role of photochemistry in establishing the large non-mass-dependent (NMD) isotopic variations observed in oxygen in solar system materials. A prime candidate process is isotopic self-shielding in the photolysis of gaseous carbon monoxide. Still at issue are the questions of where and when this might have occurred. One class of models requires low temperature...
