Persistence and degradability

Both 1- and 2-chloronaphthalene were metabolized by Pseudomonads grown on naphthalene as the sole source of carbon and energy(1). Using a sewage sludge inoculum grown on naphthalene, it was shown that 1- and 2-chloronaphthalene were both degraded on incubation with the inoculum(1). The metabolism of 1-chloronaphthalene by two species of naphthalene utilizing bacteria has been investigated(2). The bacteria were grown in mineral salts medium at pH 6.9, with 1-chloronaphthalene added as the sole source of carbon. Two metabolites were isolated 8-chloro-1,2-dihydro 1,2-dihydroxynaphthalene and 3-chlorosalicylic acid. These metabolites demonstrated that the initial site of bacterial degradation is the ring which does not contain the chlorine constituent(2).

Bioaccumulative potential

BCF values in the range of 142-338 were measured for carp exposed to 0.005 mg/l solutions of 1-chloronaphthalene during an 8 week incubation period. BCF values in the range of 142-403 were measured for carp exposed to 0.05 mg/l solutions of 1-chloronaphthalene during an 8 week incubation period. According to a classification scheme(2), these BCF values suggest bioconcentration in aquatic organisms is high(SRC).

Mobility in soil

Using a structure estimation method based on molecular connectivity indices(1), the Koc for 1-chloronaphthalene can be estimated to be 3000(SRC). According to a classification scheme(2), this estimated Koc value suggests that 1-chloronaphthalene is expected to have slight mobility in soil(SRC).

Other adverse effects

no data available

SECTION 13: Disposal considerations

Disposal methods

Product

The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
