The bioaccumulation potential of alkyl naphthalene was estimated usig
the BCFBAF model which is part of the EPIWIN suite of models developed
by the U.S. Environmental Protection Agency. The EPIWIN program
calculates BCF values using both the Meylan model and the Arnot and
Gobas model. These QSAR models are well established and approved by the
US EPA for more than a decade. EPIWIN has been included in the OECD QSAR
Alkylnaphthalene is a UVCB substance with 4 components. For a
comprehensive assessment, the BCF of all 4 substances was determined.
The range of BCF estimates for the 4 components of the UVCB substance
are 0.9 to 34 using the Arnot-Gobas model and 3 to 102 based on the
Meylan model. The mono-alkylnaphthalene component which has the lowest
concentration (2%) had the highest BCF in models (34 to 102). BCF values
for the main components, tri-alkylnaphthalenes (53%) and
tetra-alkylnaphthalenes (28.6%), are less than 5. The highest calculated
value of 102 is proposed as a conservative estimate of the BCF.
