Analysis of Organic Contaminants and In Vitro Cytotoxicity to Test the Suitability of External Organic Matter Processing.

ABSTRACT: External organic matter (EOM), particularly from municipal waste, can contaminate soil when used to amend it. This may limit the benefits of using such an EOM to improve soil health and mitigate climate change. However, certain treatments may reduce the initial contaminant load of EOM. This study aimed to evaluate whether EOM processing can reduce its cytotoxicity and the concentration levels of 34 persistent and emerging organic contaminants. Sewage sludge and a mixture of manure and straw, processed by pyrolysis and anaerobic digestion to generate biochar and digestate, respectively, were selected for this study. An in vitro fish cell cytotoxicity test was performed to assess the toxicity of organic and aqueous extracts from the EOMs. It was found that organic contaminants are gen
