Notes:

1 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.

2See also regulation 4(2)(d).

3 See the definition of “pesticides and related products” in regulation 2.

4 The parametric value applies to each individual pesticide.

5Pesticides: Total” means the sum of the concentrations of the individual pesticides detected and quantified in the monitoring procedure.

6 The specified compounds are:

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.

7 The parametric value applies to the sum of the concentrations of the individual compounds detected and quantified in the monitoring process.

8 The specified compounds are:

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.
