Equity Watch - Global Environmental Government Unit - Centre for Science and Environment (CSE)
This is called the enhanced greenhouse effect. The blanket has become thicker, to the point that today, the global climate system is getting stressed out. The global climate system consists of complex flows of energy and chemical reactions within and between atmosphere, land, ocean and biota. As one element (the radiant energy balance) goes out of gear, so ...

Earth Would Not Pass the Smog Test!
Throw in some pollutants, water vapor and particulate matter and you've got smog. Ozone is a product of chemical reactions between hydrocarbons and nitrogen oxides in the presence of sunlight. It is created when oxides of nitrogen (NOx) and volatile organic compounds (VOCs) react in heat and sunlight. NOx is produced and emitted by the burning of ...

EnviroScape -- Environmental models for school and community education
Algae loves AMD. Wetlands, constructed wetlands may be a solution to AMD. "In many areas, acid drainage forms naturally when certain minerals come into contact with water, air and bacteria. This contact and the chemical reactions that take place are part of the weathering process. The weathering of the rocks and minerals in the creek slowly ...

Integrated Assessment Briefs
In the 1960s, experiments used radioisotopes to "tag" forest nutrients, shedding light on key chemical reactions in the nutrient cycle and revealing the role played by bacteria and insects in breaking down organic matter. ORNL has gone on to examine the effects of radioactive and chemical contamination of the food chain: the ecological effects of releasing heated water from power plants ...

GAIA Model Base MESOPUFF: Mesoscale Puff Model
Each puff may follow an independent trajectory, it has a different diffusion, different chemical reactions, and dry and wet deposition. Up to five pollutants may be modelled: sulphur dioxide, sulphate, hydrogen oxide, nitric acid and nitrates. It works with time scales of few days. The package includes a preprocessor for ...

Groundwater Geochemistry and Remediation | Earth Sciences | University of Waterloo
Mathematical modelling has focused on the development of fully-coupled reactive transport codes that can account for thermodynamic and kinetic controls on chemical reactions between groundwater and the aquifer material. Remediation research is focused on the development of passive, in situ, methods including permeable reactive barriers. Our research is done ...

Terms Beginning With "O"
It can seriously impair the respiratory system and is ... Air Act required EPA to set standards. Ozone in the troposphere is produced through complex chemical reactions of nitrogen oxides, which are among the primary pollutants emitted by combustion sources; hydrocarbons, ...

Phosphorus (P) - Chemical properties, Health and Environmental effects
Red phosphorous can vary in colour from orange to purple, due to slight variations in its chemical structure. The third form, black phosphorous, is made under high pressure, looks like graphite and, ... . However, when phosphorus particles are in air they may have a protective coating that prevents chemical reactions. In water, white phosphorus is not reacting with other particles that quickly and as ...

Sulphur (S) - Chemical properties, Health and Environmental effects
Conditions in the early seas were such that simple chemical reactions could have generate the range of amino acids that are the building blocks of life ... , as well as humans. These damaging sulphur bonds are also shaped in nature during various reactions, mostly when substances that are not naturally present have already been added. They are unwanted because ...
