4. Factors affecting bio-accumulation of PCBs in fish.
? Ecological niches: feeding habits affects PCBs
accumulation in freshwater fish cultured in
wastewater system at Au Tau.
? Possible uptake pathways for sediment-sorbed PCBs
accumulated in tilapia: ingestion sediment and/or
contact with contaminated particles contributed to the
major uptake route rather than water.
