Sentence examples for toxicant dose from inspiring English sources

Metabolites of tobacco smoke constituents can be quantified in urine and other body fluids providing a realistic measure of carcinogen and toxicant dose in a smoker.

For the hazard characterization step, it is generally accepted that once detectable, a response of an organism to a toxicant increases proportionally with the level of exposure until reaching an upper-limit or maximal-effect level (Emax) beyond which increasing toxicant dose will not increase the response (known as a monotonic dose-response).

LoadBDSM allows the upload of data and experiment details using controlled semantics for developmental exposure (toxicant, dosing scenario, intervention), biological sample (species, tissue, stage) and disease outcome (time, risk, phenotype).

The lung appears to be uniquely sensitive to As, in that chronic ingestion of relatively low, nonovertly toxic doses can elicit increased disease risk, whereas other lung toxicants require inhalation to elicit similar disease risks.

Were parallel reference toxicant toxicity test conducted?

Having such tools to track small molecule and free radical diffusion will enable studies that can better address low-dose toxicant exposures that are relevant to disease pathogenesis.

Considering this effect culmination enables to link long-term effects of repeated low-dose toxicant pulses at concentrations that should have no effect on the number of individuals within a population (i.e., below the no observed effect concentration for each individual pulse).

For all integration forms, a clear dose-dependent positive response to the presence of the model toxicant nalidixic acid was observed, with biofilms displaying higher current density and detection sensitivity than planktonic and sessile cells.

A number of substances (including well-known examples of ethanol and thalidomide) are known developmental toxicants at low doses but do not display toxic properties for adults at the same concentrations.
