Structure of Dechlorane Plus®
Source: PubChem

Chlorinated flame retardants

Dechlorane Plus®, first used as a substitute for the pesticide Mirex, is a high-production volume chemical that consists of two isomers (syn and anti). In the technical mixture, the anti-isomer accounts for approximately 60 to 80% of the total isomers. Anti-Cl11-Dechlorane Plus (Cl11-Anti-DP) and anti-Cl10-Dechlorane Plus (Cl10-anti-DP) are examples for degradation products of Dechlorane Plus® after dechlorination. 1,5-Dechlorane Plus® Mono-Adduct is a transformation product (Diels Alder adduct) of Dechlorane Plus®. Dechlorane 602, Dechlorane 603 and Dechlorane 604 are similar substances to Dechlorane Plus®, also being replacement substances for Mirex.
Dechlorane Plus® is a potential substitute for DecaBDE and suspected to be highly persistent, to show biomagnification and potential for long-range transport.

Zebra mussel Common mussel species as invasive animal in rivers and lakes with high information level for water pollution
Bream Bioindicator in rivers and lakes
Suspended particulate matter Fine insoluble mineral or organic particles in the water phase
Blue mussel One of the most important edible mussel species common in the North and Baltic Sea
Eelpout As the only viviparous fish in German nearshore waters, it is a bioindicator in nearshore coastal marine ecosystems.
Herring gull Inshore, the herring gull mainly feeds from the sea: upon fish, mussels, and crabs.
Common spruce A major primary producer in semi-natural and anthropogenic affected ecosystems.
Pine A major primary producer in semi-natural and anthropogenic affected ecosystems.
Lombardy poplar A deciduous tree typical of ecosystems close to dense conurbations and an indicator for the characterisation of the immission situation during the vegetation period.
Beech As the most dominant deciduous tree species in Central Europe, it plays a significant role in most nearly natural and also anthropogenically influenced forest ecosystems up to an altitude of 1100 m.
Roe deer, one-year-old The roe deer is the most common of the larger herbivores (first order-consumer) to be found in the wild in Europe.
Earthworm (Aporrectodea longa) As an organism living at ground level, it is a major driver of the decomposition of organic material (e.g. plant litter).
Earthworm (Lumbricus terrestris) As an organism living at ground level, it is a major driver of the decomposition of organic material (e.g. plant litter).
Soil Soil is livelihood and biosphere for humans, animals, plants and soil organisms. All the substances brought in are transported, transformed and/or accumulated in the soil.
