Parysgroen

#50C878

Parysgroen ((de) Schweinfurter Grün) is 'n pigment, maar ook 'n dodelike gifstof.[1] Dit is koper (II) arsenietasetaat, 'n dubbele sout wat koper, arseen, en die anioon van asynsuur verbind. Die chemiese formule is Cu(CH3COO)2 · 3 Cu(AsO2)2.

Parysgroen is sedert die 19de eeu as 'n kleurstof in skilderwerk gebruik. Dit word aangeprys vir sy kleurintensiteit en ligspoed, maar sy giftigheid is reeds lank bekend. Sy toksiese eienskappe en gebruike dateer terug na die Tweede Wêreldoorlog, toe dit as 'n plaagdoder vir rotte in Parys en malariamuskiete in Italië en omstreke gebruik is.[2]
