EPA and EPRI studies on the effects of high levels of atmospheric sulfates reflect the situation of the early 1970's in the Northeast. Emissions, deposition, and transportation; ground-level fluxes; soil-sulfur reactions and river removal; and cycle balance are examined. The health and welfare ...
Mercury, a potentially toxic metal, is present in the environment as a result of both natural processes and from man-made sources. The amount of mercury mo... PG Crandall,CA O'Bryan 被引量: 0发表: 0年 Environmental Contaminants and Reproductive Abnormalities in Wildlife: Implications for Publi...

aHow natural gas travels from the earth to the points of consumption is discussed, along with the growth of the international trade in natural gas and the possibility of developing nonconventional sources of methane. 怎么天然气从地球移动到问题的消耗量与国际贸易的成长在天然气和开发一起甲烷的非传统...
The west coast on the Arabian Gulf exhibited a much higher level of pollution by man-made debris than the east coast on the Gulf of Oman. Potential sources are pointed out and comparisons with other regions of the world are discussed.
Man-made as well as natural sources contribute to the occurrence of trace constituents in the atmosphere. A strict distinction between these source types i... W Winiwarter,H Haberl,D Simpson - 《Journal of Geophysical Research》 被引量: 306发表: 1999年 ...
Xi uses this example to emphasize that scientific and technological development must be integrated with social progress. He stresses the need to deepen reforms in the management of science and technology, allowing all sources of innovation to flow freely. ...
Significant legal advances have been made towards safer driving in the past few years. Safety standards for vehicle have been raised both at the point of manufacture (制造业) and through regular road-worthiness inspections (车辆上路安检). In addition, speed limits have been lowered. Due to these...
weather events, from consumer choices to national legislation, from individual transportation to international industry, the consequences of man-made climate change are all around us. To slow, stop or even reverse climate change, we have to reduce the amount of carbon dioxide released into the ...
Mannoprotein is defined as a glycoprotein present on the surface of pathogenic fungi, such as Candida, consisting mainly of mannose residues with various linkages like α1-2, α1-3, α1-6, and β1-2. It plays a role in host-pathogen interactions and can vary in structure based on the...
