Linking Selenium Sources to Ecosystems: Mining
Thus, mining of coal seams and their associated waste rock are primary geologic selenium sources that have the potential to affect aquatic ecosystems. Selenium release to the environment during coal burning for power generation can be direct during combustion or indirect from disposal of solid combustion waste (i.e., fly ash).

Ecosystem - Selenium
Over the last decade, a large ecosystem of Open Source projects have sprouted up around Selenium. This page attempts to capture some of those projects that make use of Selenium WebDriver as a central part of what they do.
Lifetime Chronicles of Selenium Exposure Linked to ...
Aquatic ecosystems worldwide face growing threats from elevated levels of contaminants from human activities. Toxic levels of selenium (Se) shown to cause deformities in birds, fish, and mammals can transfer from parents to progeny during embryonic development or accumulate through Se-enriched diets. For migratory species that move across landscapes, tracking exposure to elevated Se is vital ...
Selenium Assessment in Aquatic Ecosystems | SpringerLink
Selenium is a naturally occurring trace element that can become concentrated and released by industrial, agricultural, petrochemical and mining activities. At concentrated levels it is toxic and has polluted ecosystems around the world.
Selenium - driver.getPageSource() differs than the source ...
The "source" code you get from Selenium seems to not be the source at all. It seems to be the HTML for the current DOM. The source code you see in the browser is the HTML as given by the server, before any dynamic changes made to it by JavaScript. If the DOM changes at all, the browser source code doesnt reflect those changes, but Selenium will.
