CONCENTRATIONS OF PBDEs, HBCDs, TBBP-A, PAH, AND PCBs IN ENGLISH LAKE WATER: FIRST REPORT FROM THE OPAL PROJECT
Introduction: As part of a recently-commenced 5 year project studying the contamination of English freshwater lakes by persistent organic chemicals, this paper reports the concentrations of PBDEs, HBCDs, TBBP-A, PAH, and PCBs in water from 9 English lakes. Methods and Materials: Each lake was sampled on 3 occasions at quarterly intervals between July 2008 and January 2009 providing a summer, autumn, and winter sample for each site. Results and Discussion: For PBDEs, PAH, and PCBs, concentrations are in line broadly with those reported previously for the UK and elsewhere. To our knowledge, these are the first such data for HBCDs and TBBP-A. Very little seasonal variation in concentrations is evident. Concentrations of TBBP-A exceed those of PBDEs and HBCDs at every site, suggesting that despite its principal use as a reactive flame retardant, TBBP-A is migrating into the environment. Concentrations at each site of ΣHBCDs and TBBP-A are significantly positively correlated, indicating a common source or sources. Averaged across all sites the average±σn proportion of ΣHBCDs, TBBP-A, BDE-47, and BDE-99 associated with the freely-dissolved phase was 47±4.7％, 61±2.9％, 36±8.3％, and 29±7.3％ respectively.
