Chemical Class: Organochlorine
Introduction: Lindane is an organochlorine
insecticide and fumigant which has been
used on a wide range of soil-dwelling
and plant-eating (phytophagous) insects.
It is commonly used on a wide variety
of crops, in warehouses, in public health
to control insect-borne diseases, and
(with fungicides) as a seed treatment.
Lindane is also presently used in lotions,
creams, and shampoos for the control of
lice and mites (scabies) in humans.

Technical lindane is comprised of the
gamma-isomer of hexachlorocyclohexane,
HCH. Five other isomers (molecules with
a unique structural arrangement, but identical
chemical formulas) of HCH are commonly
found in technical lindane, but the gamma-isomer
is the predominant one, comprising at
least 99% of the mixture of isomers. Data
presented in this profile are for the
technical product unless otherwise stated;
lindane, HCH, or BHC refer to technical
lindane, i.e., Gamma-hexachlorocyclohexane.
Gamma-HCH has been shown to be the insecticidally
effective isomer.
Lindane may also be found in formulations
with a host of fungicides and insecticides.
It is available as a suspension, emulsifiable
concentrate, fumigant, seed treatment,
wettable and dustable powder, and ultra
low volume (ULV) liquid.

Target Pests: Termites and soil borne
pests in particular
Ecological Effects:
-
Effects
on birds: Lindane is moderately
to practically nontoxic to bird species,
with a reported LD50 of more than 2000
mg/kg in the mallard duck. The 5-day
dietary LC50 of lindane in Japanese
quail is 490 ppm The LC50 values of
lindane in pheasant and bobwhite quail
are 561 ppm and 882 ppm, respectively
. Egg-shell thinning and reduced egg
production has occurred in birds exposed
to lindane . Lindane can be stored in
the fat of birds; birds of prey in the
Netherlands contained up to 89 ppm in
their fat . Residues can also find their
way into egg yolks at measurable concentrations
for 32 days after dosing.
-
Effects
on aquatic organisms: Lindane
is highly to very highly toxic to fish
and aquatic invertebrate species. Reported
96-hour LC50 values range from 1.7 to
90 ug/L in trout (rainbow, brown, and
lake), coho salmon, carp, fathead minnow,
bluegill, largemouth bass, and yellow
perch . Water hardness did not seem
to alter the toxicity to fish, but increased
temperature caused increased toxicity
for some species and decreased toxicity
for others. Reported 96-hour LC50 values
in aquatic invertebrates were: in Daphnia,
460 ug/L; in scuds, 10-88 ug/L; and
in Pteronarcys (stone flies), 4.5 ug/L
. The bioconcentration factor for the
compound is 1400 times ambient water
concentrations, indicating significant
bioaccumulation
-
Effects
on other organisms: Lindane
is highly toxic to bees.
-
Breakdown
in soil and groundwater: Lindane
is highly persistent in most soils,
with a field half-life of approximately
15 months When sprayed on the surface,
the half-life was typically much shorter
than when incorporated into the soil
. It shows a low affinity for soil binding
, and may be mobile in soils with especially
low organic matter content or subject
to high rainfall. It may pose a risk
of groundwater contamination. The pesticide
has been found in a significant number
of groundwater samples in New Jersey,
California, Mississippi, South Carolina,
and in Italy at concentrations of less
than 1 ug/L (ppb) Lindane is a contaminant
in water in the Great Lakes at very
low concentrations as well.
-
Breakdown
in water: Lindane is very stable
in both fresh and salt water environments,
and is resistant to photodegradation.
It will disappear from the water by
secondary mechanisms such as adsorption
on sediment, biological breakdown by
microflora and fauna, and adsorption
by fish through gills, skin, and food.
-
Breakdown
in vegetation: Plants may pick
up residues from not only direct application,
but through water and vapor phases.
Persistence is seen when plants are
rich in lipid content, and crops like
cauliflower and spinach will build up
less residue than crops like carrots.
The metabolism in plants is not well
understood, but carrots are estimated
to metabolize lindane with a half-life
of just over 10 weeks (based on plant
uptake) whereas it may have a half-life
in lettuce of only 3 to 4 days.
-

Lindane is a colorless crystal compound.
