Legal limit values

Exhaust emissions of CO, unbumed hydrocarbons, and nitrogen oxides reflect combustion conditions rather than fuel properties. The only fuel component that degrades exhaust is sulfur the SO2 concentrations ia emissions are directly proportional to the content of bound sulfur ia the fuel. Sulfur concentrations ia fuel are determined by cmde type and desulfurization processes. Specifications for aircraft fuels impose limits of 3000 —4000 ppm total sulfur but the average is half of these values. Sulfur content ia heavier fuels is determined by legal limits on stack emissions.

The relation of measured results to given values, e.g., critical levels, legally fixed values, regulatory limits, maximum acceptable values, is of continual relevance in analytical chemistry. In the analytical reality, the problematic nature of detection leads to the test statistics, strictly speaking to the t-test (Currie [1995, 1997] Ehrlich and Danzer [2006]). By means of that, it is tested, if the determined analytical result is significantly different from the average blank of the critical value, respectively. 

The result of a quantitative chemical measurement is not an end in itself. It has a cost and therefore it always has a purpose. It may be used, for example, in checking products against specifications or legal limits, to determine the yield of a reaction, or to estimate monetary value. 

Threshold Limit Value Airborne concentrations of substances devised by the ACGIH that represent conditions under which it is believed that nearly all workers maybe exposed day after day with no adverse effect. TLV s are advisory exposure guidelines, not legal standards, based on evidence from industrial experience, animal studies, or human studies when they exist. There are three different types of TLV s Time Weighted Average (TLV-TWA) Short Term Exposure Limit (TLV-STEL) and Ceiling (TLV-C). (See also PEL)... 

When subjects consumed 7 oz. of 80 proof alcohol (in orange juice) in 20 minutes, mean blood levels rose only to 0.07% (Fig. 107). This finding was in line with results reported by Sidell and Pless (1971). Only 2 subjects exceeded a level of. 10%. The rate of elimination was linear after 2 hours, averaging 15 mg% hourly, somewhat less than reported in many other studies. The mean peak value did not exceed the (then) legal limit of 0.10, even after consuming what most would consider a large dose of alcohol. Similar results have been reported by other investigators.

For Sauternes, no measured data are given. Value in parentheses corresponds to the legal limit before 2009. For Sauterenes, the values are converted from miUiequivalent. 

A level that should not be breached. In EU law, a limit value is legally binding. 

Critical threshold values (e.g. in health and environment) cannot generally be technically justified with a small uncertainty. However, if a legal limit is set, there must be test methods suited for the purpose. Reference is made to a recent ILAC Guide. 

With ceramic membranes (typical pore size 0.2 pm) this legal limit of 10 ppm is easily obtained [18]. Average membrane flux is 150 1/m h values are reported between 125 and 6001/m h [19]. The interval between cleanings or the maintenance interval can amount to 1000 h. By combination of the membrane unit with a static separator the concentration factor can be as high as 180, the oil content in the final concentrate can amount to over 90%. The pay-back time for such an installation would be less than two years at a cost of NLG 94/m effluent, and related to the present costs of treatment [18].
