08/04/2009 Drinking water 0.00088 ng/l Study on levels of mono and dichloronaphthalene in
drinking water in Japan. After chlorination, levels of
0.03–0.44 ng/litre for chloronaphthalene and levels of
not detected to 0.15 ng/litre for dichloronaphthalene.
Multiply by 2l per day for adult consumption. Convert
from ng/l to μg/l divide by 1,000.

08/04/2009 Drinking water and
food
0.0001 μg/day Chloronaphthalene can be found in drinking water
after chlorination processing, leading to a daily intake
in the order of 0.1 ng. The exposure of the population
from 1- and 2-chloronaphthalene from food is
negligible. Convert from ng/l to μg/l divide by 1,000.

08/04/2009 Ambient air 0.02 μg day-1 According to TSD (1993) the lower chlorinated
naphthalenes can be found in ambient air in the
neighbourhood if different sources, from these data a
concentration in the order of 1 ng/m 3 can be estimated
in residential areas. Conversion from original data:
multiply by 20m 3 . Convert from ng/day to μg/day
divide by 1,000.
