However, these radiolabeled precursors cannot be used in organisms as they pose toxicity and other challenges.
Unlike many other cross-linking agents and/or methods (e.g., excessive vapor phase cross-linking) that may pose a risk of toxicity, our study demonstrated that these nanofibrous materials are well tolerated by anterior segment tissues.
Although the roots are used externally, the relative safety is obviously advantageous since systemic administration and or systemic absorption of the root extract from site of topical application (as employed in ethnomedicine) may pose no risk of acute toxicity.
Toxicity interaction within mixtures may pose potential hazards and risks to the environmental safety and human health.
The challenges of reducing and refining animal use in the assessment of safety and toxicity of agents that may pose hazard to humans and the environment are immense.
The leakage, liquid or vapor, may pose a variety of hazards in context to toxicity, flammability, health, radioactivity, environmental, or may simply be unpleasant.
Surfactant toxicity and inherent biodegradability of surfactants may pose additional challenges as discussed in this review.
The widespread use of this herbicide and the measured concentrations in humans and in the environment have raised concerns about its toxicity and the risk that it may pose for human and wildlife health.
To gain a better understanding whether the accidental release of metal-containing NPs may pose a threat to non-target species, we collected toxicity data on these NPs for algae, crustaceans, fish, bacteria, yeast, nematodes, protozoa and mammalian cell lines and compared the toxicity values of NPs to target- and non-target organisms.
