Maximum admissible concentration MAC

The assay conditions were optimized with respect to antibody and tracer concentration to obtain maximal sensitivity at 0.1 ppb, the current maximum admissible concentration (MAC) in drinking water.

Table 3. Maximum admissible concentrations (MAC) of major atmospheric pollutants for humans and for vegetation.

Because of its widespread use, relatively large amounts of these compounds are released into the environment and some of them enter the food chain. They have become ubiquitous in the environment.The most commonly used phthalates have been included in the list of priority pollutants in several countries. These are dimethyl- (DMP), diethyl- (DEP), di- -butyl- (DnBP), butylbenzyl- (BBP), bis(2-ethyUiexyl)- (DEHP), and di- -octyl (DnOP) phthalates. The United States Environmental Protection Agency (US EPA) has established a maximum admissible concentration (MAC) in water of 6 /rg/1 for DEHP." " In recent years, considerable attention has been paid to human exposure to phthalates because of the suspicion of its carcinogenic and estrogenic properties. " " ... 

Toxicological studies of bromate have provided continuous evidence of its possible carcinogenicity (Km-okawa et al, 1990). As a result a maximum admissible concentration (MAC) of 10 pg/L bromate in drinking waters is recommended by the US ERA (US EPA,1997), the Emopean Commission (Council Directive 98/83) and the WHO (WHO, 1991), this limit has been defined primarily on the basis of the detection...

Maximum Admissible Concentration (MAC) = 0.1 og/L) for pesticides in drinking water. Recent studies have been aimed at increasing the sensitivity of CMIA by attaching several M-CO probes borne by PAMAM dendrimers to antibodies [19] or to avidin which can then be used in conjugation with biotinylated antibodies [18]. Detection of these labeled antibodies can be carried out on membranes, making it possible to omit the step of extracting the free fraction by solvent. 

By using potassium decanoate as an example of a highly charged micelle of well-defined volume, the phase nature and extension for competing phases co-existing with micelles at the maximum admissible concentration (MAC) can be explicitly predicted. The polarity of the solute is modified through the value of the standard chemical potential, For a non-polar...
