THE CONTINUOUS MONITORING OF FIELD WATER SAMPLES WITH A NOVEL MULTI-CHANNEL TWO-STAGE MINI-BIOREACTOR SYSTEM

摘要

Toxicity monitoring of field water samples was performed using a novel multi-channel two-stage mini-bioreactor system and genetically engineered bioluminescent bacteria for the con- tinuous monitoring and classification of the toxicity present in the samples. The toxicity of various samples spiked with known endocrine disrupting chemicals and phenol was also investigated for system characterization. The field samples used in this study were obtained from two different sites on a monthly basis-from a drinking water treatment plant, referred to as site N, and from a stream near a dam which is currently being constructed, referred to as site T.
