Notes:
(i)The parametric value refers to the residual monomer concentration in the water as calculated according to specifications of the maximum release from the corresponding polymer in contact with the water. This is controlled by product specification.
(ii)See the definition of “pesticides and related products” in regulation 2(1). The parametric value applies to each individual pesticide.
(iii)“Pesticides: Total” means the sum of the concentrations of the individual pesticides detected and quantified in the monitoring procedure.
(iv)“PAH” means Polycyclic Aromatic Hydrocarbons, the specified compounds being:
– benzo(b)fluoranthene
– benzo(k)fluoranthene
– benzo(ghi)perylene
– indeno(1,2,3–cd)pyrene.
The parametric value applies to the sum of the concentrations of the individual compounds detected and quantified in the monitoring process.
(v)The parametric value applies to the sum of the concentrations of the individual compounds detected and quantified in the monitoring process.
(vi)“THM: Total” means total Trihalomethanes, the specified compounds being:
– chloroform
– bromoform
– dibromochloromethane
– bromodichloromethane.
The parametric value applies to the sum of the concentrations of the individual compounds detected and quantified in the monitoring process.
