Consumption of drinking water and/or seafood, for example, might result in chronic exposure to low levels of toxins, at concentrations below regulatory levels or even conventional detection limits [ 21].
Benefiting from the large specific surface area and high porosity of nanofibrous membranes, the strips achieved ultralow naked eye detection limit of 0.06 mg m−3 (below the regulatory level of 0.1 mg m−3), wide linear range from 0.12 to 6 mg m−3, and short response time (15 min) in the absence of advanced instrumentation.
the de minimis risk is defined as a level "below regulatory concern" [ 28].
In addition to the objective safety of these surfactants and LCOH in the aquatic and sediment environments, the BCFs for each of these chemicals are well below the regulatory concern levels of 2,000 5,000 (United Nations Environment Program [UNEP], 2001; European Commission, 2003).
These institutions had one or more regulatory capital ratios that fell below regulatory minimum levels at some point over the stress test projections, including three that fell below the 5 percent benchmark for the Tier 1 common ratio.
Hence, the utility of FT-NIR to discriminate DON contamination in unprocessed samples below the set EU regulatory level was demonstrated [ 13].
With few exceptions though, contemporary levels of glyphosate in the air, water, and food result in typical human exposure estimates that remain well below the "levels of concern" or "Acceptable Daily Intakes" established by regulatory bodies around the world.
Generally, a below-normal level of TSH suggests hyperthyroidism.
