Organochloro pesticides
Organochloro hydrocarbons with insecticidal properties
The development and production of organochloro pesticides began already in the first half of the last century. Compounds like DDT, pentachlorophenol, hexachlorobenzene, lindane, aldrin, dieldrin and chlorophen were extensively used as plant protection products and pesticides all over the world. In the mid 1950s their negative properties became evident, e.g. their persistence and their high potetial for bioaccumulation and biomagnification. Moreover, some compounds are suspected to be carcinogenic and endocrine disruptive. As a consequence many industrial countries banned or restricted the use of organochloro pesticides in the 1970s.
A worldwide ban or restriction of the most hazardous organochloro pesticides followed when the Stockholm Convention and its amendment became effective in 2004 and 2009, respectively.

As the only viviparous fish in German nearshore waters, it is a bioindicator in nearshore coastal marine ecosystems.

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.
