Substance Infocard
DDT total
EC / List no.: -
CAS no.: -
Mol. Formula:
Here you can find all of the regulations and regulatory lists in which this substance appears, according to the data available to ECHA. This substance has been found in the following regulatory activities (directly, or inheriting the regulatory context of a parent substance):
| Region | Legislation | Emission medium | Process/equipment | Maximum emissions | Average emissions | Notes | |||
|---|---|---|---|---|---|---|---|---|---|
| Maximum limit | Maximum sampling duration | Average limit | Average sampling duration | ||||||
| European Union | Water Environmental Quality Standards Directive | Surface waters other than inland surface waters | 0.025 µg/l | 1.0 yr | Unless otherwise specified the EQS parameter expressed as an annual average value (AA-EQS) applies to the total concentration of all isomers. This substance is not a priority substance but one of the other pollutants for which the EQS are identical to those laid down in the legislation that applied prior to 13 January 2009. DDT total comprises the sum of the isomers 111-trichloro-22 bis (p-chlorophenyl) ethane (CAS number 50-29-3; EU number 200-024-3); 111-trichloro-2-(o-chlorophenyl)-2-(p-chlorophenyl) ethane (CAS number 789-02-6; EU number 212-332-5); 11-dichloro-22 bis (p-chlorophenyl) ethylene (CAS number 72-55-9; EU number 200-784-6); and 11-dichloro-22 bis (p-chlorophenyl) ethane (CAS number 72-54-8; EU number 200-783-0). Where the MAC-EQS are not applicable the AA-EQS values are considered protective against short-term pollution peaks in continuous discharges since they are significantly lower than the values derived on the basis of acute toxicity. | ||||
