Abstract
Diphenyl sulfone (DPS), ortho-hydroxybiphenyl (OPP), and para-hydroxybiphenyl (PPP) were found entering a small lake receiving contaminated groundwater discharge from a Superfund Site in Woburn, MA. Concentrations up to 450 Ig/L of DPS, 100 Ig/L of OPP, and 230 Ig/L of PPP were found in the hypolimnion, whereas epilimnetic concentrations of all the chemicals were significantly lower (normally <5 Ig/L). The co-occurrence of these compounds, byproducts of the industrial synthesis of phenol, combined with the known historical production of phenol adjacent to the lake strongly indicate that these semivolatiles derived from the manufacturing of phenol. Yearround field studies and laboratory experiments were combined in a mass balance approach to model these pollutants’ chemodynamic behavior. All three chemicals were readily biodegradable during warm periods. OPP and PPP showed significant photodegradation rates under sunlight. DPS, OPP, and PPP were of low toxicity and were not mutagenic in human MCL-5 and H1A1V2 cell lines.
