Causal relationships among biological toxicity, geochemical conditions and derived DBPs in groundwater

- We clarified the roles of environmental factors on groundwater contamination patterns.
- RDA biplots revealed the relationships between the dominant DBPs and these factors.
- BDCAA and As + 5 are two main contributors to bio-toxicity in a coastal area of Taiwan.
- Seawater intrusion with Br-concentration indirectly increased the bio-toxicity.
