Moreover, Ms. Hammond said the revision proposed this year was limited to several narrow aspects of the rules -- primarily involving the maximum permitted concentration of pollutants in the groundwater.
The effluent were all far below the permitted concentration level in the current drinking water standard.
These de minimis thresholds are primarily based either on the maximum permitted concentration specified by the Ordinance on Drinking Water (Trinkwasserverordnung), or, if no maximum permitted concentration has yet been established, on toxicologically and ecotoxicologically derived threshold values.
Riders are permitted to use the drug for medical purposes below a certain threshold, but Ulissi's "adverse" sample contained almost twice the permitted concentration.
After the "aeration biofiltration" cascading treatment, the effluent iron, manganese and ammonia were all far below the permitted concentration level in the current drinking water standard.
These first results showed that the freely dissolved concentration of highly HOCs can be significantly reduced due to sorption to natural OM - already beneath the permitted concentration of 2 mg L-1 TOC in the dilution water according to OECD TG 305.
As described, the dissolved iron, manganese and ammonia concentrations were 15 17, 1.5 1.7 and ~ 1.0 mg/L, which were much higher than that in the current drinking water standard (maximum permitted concentration are 0.2, 0.05 and 0.5 mg/L, respectively) (Tekerlekopoulou et al. 2013).
Results showed that the gas sensor system covered a linear detection range from 8 mg/L to 5600 mg/L (R = 0.9963, n = 7) with a detection limit of 6.2 mg/L (S/N = 3), which was below the standard permitted concentration.
Furthermore, Commission regulation (EU) No 1004/2014 has lowered the maximum permitted concentration of butyl- and propylparaben in cosmetics and it has also banned them in leave-on products designed for application on the nappy area of children under three years of age.
The maximum permitted concentration when diluted in 0.9% saline is 5.4 mg ml−1.
