FARBLOSE BIS WEISSE KRISTALLE.
CHEMISCHE GEFAHREN
Zersetzung beim Erhitzen oder Verbrennen unter Bildung giftiger und reizender Rauche mit Stickstoffoxiden, Phosphoroxiden und Schwefeloxiden. Greift Kupfer an.
ARBEITSPLATZGRENZWERTE
TLV nicht festgelegt (ACGIH 2005).
MAK nicht festgelegt (DFG 2005).
AUFNAHMEWEGE
Aufnahme in den K?rper durch Inhalation des Aerosols, über die Haut und durch Verschlucken.
INHALATIONSGEFAHREN
Verdampfung bei 20°C vernachl?ssigbar; eine gesundheitssch?dliche Partikelkonzentration in der Luft kann jedoch beim Versprühen oder Dispergieren schnell erreicht werden, vor allem als Pulver.
WIRKUNGEN BEI KURZZEITEXPOSITION
WIRKUNGEN BEI KURZZEITEXPOSITION: M?glich sind Auswirkungen auf das Nervensystem mit nachfolgenden Kr?mpfen und Atemversagen. Cholinesterasehemmer. Exposition kann zum Tod führen. Die Auswirkungen treten u.U. verz?gert ein. ?rztliche Beobachtung notwendig. (s.Anm.)
WIRKUNGEN NACH WIEDERHOLTER ODER LANGZEITEXPOSITION
Cholinesterasehemmer. Kumulative Wirkung m?glich (s. AKUTE GEFAHREN/SYMPTOME). (S. Anm.)
LECKAGE
NICHT in die Kanalisation spülen. Verschüttetes Material in abdichtbaren Beh?ltern sammeln; falls erforderlich durch Anfeuchten Staubentwicklung verhindern. Reste sorgf?ltig sammeln. An sicheren Ort bringen. Pers?nliche Schutzausrüstung: Atemschutzger?t, P2-Filter für sch?dliche Partikel.
R-S?tze Betriebsanweisung:
R22:Gesundheitssch?dlich beim Verschlucken.
R50/53:Sehr giftig für Wasserorganismen, kann in Gew?ssern l?ngerfristig sch?dliche Wirkungen haben.
S-S?tze Betriebsanweisung:
S24:Berührung mit der Haut vermeiden.
S36:DE: Bei der Arbeit geeignete Schutzkleidung tragen.
S60:Dieses Produkt und sein Beh?lter sind als gef?hrlicher Abfall zu entsorgen.

Chemische Eigenschaften
Bensulide is and amber, viscous liquid, or
forms colorless or white crystalline solid below 34.4 C.
Combustible. Commercial product is available as an
emulsifiable concentrate.
Verwenden
Bensulide is an herbicide used for preemergent control of
annual grasses and broadleaf weeds in agricultural crops
(60–65% of all use). Current registered use sites are carrots,
fruiting vegetables, leafy vegetables (mostly head lettuce),
dry bulb vegetables (onions), cucurbits (mostly melons), and
cole crops (cauliflower, cabbage, broccoli, broccolini, and
broccoflower). Bensulide can also be used on field-grown
herbaceous plants and field-grownbulbs. Products containing
bensulide are intended for outdoor homeowner use on lawns
and ornamentals, and application by professional lawn care
operators to lawns, ornamentals, parks, and recreation areas.
Hazard
Highly toxic, cholinesterase inhibitor. Use
may be restricted.
Landwirtschaftliche Anwendung
Herbicide: A selective pre-emergence herbicide used to control
bluegrass, crabgrass and other annual grasses and broadleaf
weeds in agriculture crops, cotton and turf. It is widely
used on golf courses and home lawns. Target weeds also
include barnyardgrass, burning nettle and canarygrass.
Not approved for use in EU countries.

m?gliche Exposition
A selective preemergence organophosphate
herbicide used to control bluegrass, crabgrass and
other annual grasses and broadleaf weed s in agriculture
crops, cotton and turf. It is widely used on golf courses and
home lawns. Target weeds also include barnyard grass,
burning nettle, and canary grass.
Carcinogenicity
Bensulide was given in the diet
for 104 weeks to rats at levels to achieve doses of 0, 1, 15, or
60 mg/kg/day . No cholinergic signs were observed at
any dose. Increased absolute liver weights accompanied by
mild histopathological changes (hepatocyte vacuolation and
eosinophilic foci) occurred at 60 mg/kg/day, but there was no
evidence of carcinogenic potential.
Bensulide was given in the diet for 78 weeks to mice at
levels to achieve 0, 1, 50, or 200 mg/kg/day . Survival
rates, clinical observations, and hematological parameters
were unaffected at all doses. Decreased overall body weight
gains, increased absolute and relative liver weights accompanied
by histopathological changes (pale foci, cell atypia,
and cell foci) occurred at 200 mg/kg/day (males only).
Overall body weight gain was also reduced in males at
50 mg/kg/day, but there was no evidence of carcinogenic
potential.

Inkompatibilit?ten
Incompatible with oxidizers; chlorates
nitrates, peroxides. Decomposes slowly in light and strong
UV. Corrosive to copper, aluminum, magnesium, zinc.
Slowly hydrolyzes in water, releasing ammonia gas and
forming acetate salts. In the presence of strong reducing
agents such as hydrides, organophosphates form highly toxic
and flammable phosphine gas. Contact with oxidizers can
cause the release of toxic oxides of phosphorus. Stable @
80 C for 50 hours; decomposes @ 200° C in 18 40 hours.
Waste disposal
Destruction by alkali hydrolysis
or incineration. Containers must be disposed of properly
by following package label directions or by contacting your
local or federal environmental control agency, or by contacting
your regional EPA office.
