The phrase "at high exposures" is correct and usable in written English.
It can be used in contexts discussing the effects or risks associated with high levels of exposure to substances, environments, or conditions.
Example: "The study found that adverse health effects were more pronounced at high exposures to the chemical."
Alternatives: "under significant exposure" or "with elevated exposure levels".
Some neurochemical or neurobehavioral effects have been reported at high exposures.
If no adverse effects are observed in those species at high exposures, confidence of negligible ecological risk from the use of the pest control method is increased.
"While elemental mercury has been associated with adverse health effects at high exposures, the levels released by dental amalgam fillings are not high enough to cause harm in patients," the agency said in a statement.
For this reason most low exposure studies rely on a dose linear assumption which extrapolates data obtained at high exposures to lower doses assuming that the effect is linearly dose dependent.
While there is convincing evidence that fine particulate matter causes cardiovascular mortality and morbidity, little of the evidence is based on populations outside of high income countries, leaving large uncertainties at high exposures.
But though he never did nuclear research, a classmate did, and it was through him that Dr. Hall learned that nuclear physicists were bedeviled by a problem with the germanium used in devices that detected the gamma rays given off by radioactive activity — rays that are deadly at high exposures.
The Statue of Liberty is at "high exposure" risk from increasingly punishing storms.
Pooled odds ratio (OR) of mortality at high exposure values versus low exposure values was estimated.
Lead is part of a class of inorganic chemical contaminants that can damage internal organs at high exposure rates.
For the Ag ENMs with different size ranges, differences in behavior and/or effect were only observed at high exposure concentrations.
Surprisingly, Ag was found to stimulate gill Cu binding especially at high exposure concentrations, whereas, Cu had no effect on gill Ag binding.
