Shellfish like oysters, crabs and shrimp are much slower at removing contaminants -- one study found that oysters continued to be contaminated seven years after an oil spill.
Sewage from a United Nations camp contaminated one of Haiti's largest rivers, the report said.
Romania said today that it would not pay compensation to any other country affected by a cyanide spill that has contaminated two rivers.
Traces of polonium, the substance used to kill the former Russian agent, were found to have contaminated four people in Hamburg.
He noticed that a mold had contaminated one of his cultures, causing the bacteria in its vicinity to undergo lysis (membrane rupture) and die.
INTERACTIVE FEATURE Selected documents that relate to how natural gas extraction contaminated one family's water supply, with key sections highlighted and annotated to explain their meaning.
More than 20% of all Belarusian forests were contaminated, nine factories were forced to shut down and more than 2 million of its people were affected by radiation, including 500,000 children.
The team's 31 research wells in areas of Hanoi near the Red River showed that aggressive pumping of a safe aquifer over the last 20 years had pulled water more than a mile in from a contaminated one.
Noise contaminated zero problems involve functions that cannot be evaluated directly, but only indirectly via observations.
In August 2014, the mining company faced close scrutiny after a toxic spill at its largest copper mine, in the northern state of Sonora, contaminated two rivers nearby.
We investigate the application of numerical bifurcation analysis for studying the solution set of such noise contaminated zero problems, which is highly relevant in the context of equation-free analysis (coarse grained analysis) and bifurcation analysis in experiments, and develop specialized algorithms to address challenges that arise due to the presence of noise.
