Abstract
The biodegradability of 5 different commercially available common photographic developers and their ingredients hydroquinone, isoascorbic acid, and its sodium salt was determined in parallel using the OECD-screening-test (OECD 301E). The results obtained from the degradation test on hydroquinone were compared with the results of other laboratories. Biodegradability of developers containing isoascorbic acid was in the same range as of comparable products containing hydroquinone. Biologische Abbaubarkeit von Photoentwicklern und ihren Inhaltsstoffen, insbesondere von Hydrochinon und Isoascorbinsaure Die biologische Abbaubarkeit von 5 verschiedenen kommerziell erhaltlichen typischen Photoentwicklern und deren Inhaltsstoffen Hydrochinon, Isoascorbinsaure und ihrem Natriumsalz wurde parallel im OECD-Screening-Test (OECD 301E) gepruft. Die Abbauergebnisse aus dem Abbau von Hydrochinon wurden mit Resultaten anderer Labors verglichen. Der Abbaugrad von Photoentwicklern, die Isoascorbinsaure enthalten, war im selben Bereich wie der fur vergleichbare Photoentwickler, die Hydrochinon enthalten.
