General
No respective experimental data for dibismuth trisulfide are available. Consequently, read-across was applied using study results from bismuth. The DNEL derivation is based on the calculated NOAEL for dibismuth trisulfide.
DNEL derivation is performed under consideration of the recommendations of ECHA REACH Guidance (2010) and ECETOC (2010). In view of the data used for evaluation, the "quality of whole database factors" and "dose-response factors" are considered to amount each to a value of 1.
Long term exposure- systemic effect
Inhalation exposure
A subchronic and a subacute repeated dose toxicity test with dibismuth trisulfide are not available. Consequently, read-across was applied using study results from bismuth in order to derive the worker DNEL (long-term inhalation exposure). A 28-day repeated dose oral toxicity study with bismuth revealed a NOAEL > 1000 mg Bismuth/kg bw/day. The DNEL derivation is based on the calculated NOAEL > 2460 mg/kg bw/day for dibismuth trisulfide.
Correction of the dose descriptor:
Oral NOAEL: > 2460 mg/kg bw/day
sRV(rat): 0.38 m3/ kg bw (8 hours) [standard respiratory volume of the rat]
ABS oral (rat)/ ABS inhalation (human): 0.5 [ratio of oral absorption in the rat to inhalative absorption in the human]
sRV (human)/ wRV (human): 6.7 m3/ 10 m3= 0.67 m3 [ratio of human standard respiratory volume to worker respiratory volume]
The oral NOAEL > 2460 mg/kg bw/ day is converted in an inhalation NOAEC > 2169 mg/ m3.
Calculation of the worker DNEL:
Corrected inhalatory NOAEC for worker: > 2169 mg/ m3
Assessment factor for exposure duration (subacute to chronic): 6
Assessment factor for intraspecies differences (worker): 3
Assessment factor for other interspecies differences: 2.5
Worker DNEL (inhalation exposure) = 2169 mg/m3/ (1 x 6 x 1 x 3 x 2.5 x 1 x 1) = 2169 / 45 = 48.2 mg/ m3
Dermal exposure
A subchronic and a subacute repeated dose toxicity test with dibismuth trisulfide are not available. Consequently, read-across was applied using study results from bismuth in order to derive the worker DNEL (long-term dermal exposure). A 28-day repeated dose oral toxicity study with bismuth revealed a NOAEL > 1000 mg Bismuth/kg bw/day. The DNEL derivation is based on the calculated NOAEL > 2460 mg/kg bw/day for dibismuth trisulfide.
Considering the appropriate assessment factors, the worker DNEL (long-term dermal exposure) is calculated as follows:
Correction of the dose descriptor:
Dose descriptor of relevant study: > 24600 mg/kg bw/day (NOAEL x 10; assuming 10 % dermal absorption)
Assessment factor for exposure duration (subacute to chronic): 6
Allometric scaling factor (rat to human): 4
Assessment factor for other interspecies differences: 2.5
Assessment factor for intraspecies differences (worker): 3
Taking the above mentioned assessment factors into account, the following worker DNEL is:
Worker DNEL (dermal exposure) = 24600 mg/kg bw/day / (1 x 6 x 4 x 2.5 x 3 x 1 x 1) = 24600 / 180 = 137 mg/kg bw/day
Acute/ short term exposure- systemic effect
Inhalation
There is no indication for acute systemic toxicity of dibismuth trisulfide. The substance is not classified for inhalation toxicity. Moreover, due to its strong adhesive properties dibismuth trisulfide particles agglomerate and deposit. The vapour pressure is negligible. Taken together, its physicochemical properties exclude inhalative exposure. Also no peak exposure is expected. Therefore no DNEL is required.
Dermal
In an acute dermal toxicity study with dibismuth trisulfide according EU method B.3 and OECD 402, a LD50 value of > 2000 mg/kg bw was obtained. Thus, the test material is not classified and labelled for acute dermal toxicity, according to Directive 67/548/EEC (DSD) and Regulation (EC) No 1272/2008 (CLP). Therefore no DNEL was derived.
Acute and long term exposure- local effect
Respiratory irritation
Due to its strong adhesive properties dibismuth trisulfide particles agglomerate and deposit. The vapour pressure is negligible. Taken together, its physicochemical properties excludes inhalative exposure. Moreover, there is no indication for any adverse local effects as the substance is neither classified for inhalation toxicity nor for irritation/corrosion according to Directive 67/548/EEC (DSD) and Regulation (EC) No 1272/2008 (CLP). Therefore no DNEL is required.
Skin irritation
The test item is not classified for skin irritation/corrosion and skin sensitization according to Directive 67/548/EEC (DSD) and Regulation (EC) No 1272/2008 (CLP). Therefore no DNEL was derived.
Eye irritation
The test item is not classified for eye irritation according to Regulation (EC) No 1272/2008 (CLP) and Directive 67/548/EEC (DSD).

Long term exposure- systemic effect
Inhalation exposure
A subchronic and a subacute repeated dose toxicity test with dibismuth trisulfide are not available. Consequently, read-across was applied using study results from bismuth in order to derive the consumer DNEL (long-term inhalation exposure). A 28-day repeated dose oral toxicity study with bismuth revealed a NOAEL > 1000 mg Bismuth/kg bw/day. The DNEL derivation is based on the calculated NOAEL > 2460 mg/kg bw/day for dibismuth trisulfide.
Correction of the dose descriptor:
Oral NOAEL: > 2460 mg/kg bw/day
sRV(rat): 1.15 m3/ kg bw (24 hours) [standard respiratory volume of the rat]
ABS oral (rat)/ ABS inhalation (human): 0.5 [ratio of oral absorption in the rat to inhalative absorption in the human]
The oral NOAEL > 2460 mg/kg bw/ day is converted in an inhalation NOAEC > 1070 mg/ m3.
Calculation of the consumer DNEL:
Corrected inhalatory NOAEC for consumer: > 1070 mg/ m3
Assessment factor for exposure duration (subacute to chronic): 6
Assessment factor for intraspecies differences (consumer): 10
Assessment factor for other interspecies differences: 2.5
Consumer DNEL (inhalation exposure) = 1070 mg/m3/ (1 x 6 x 1 x 10 x 2.5 x 1 x 1) = 1070 / 150 = 7.13 mg/ m3
Dermal exposure
A subchronic and a subacute repeated dose toxicity test with dibismuth trisulfide are not available. Consequently, read-across was applied using study results from bismuth in order to derive the consumer DNEL (long-term dermal exposure). A 28-day repeated dose oral toxicity study with bismuth revealed a NOAEL > 1000 mg Bismuth/kg bw/day. The DNEL derivation is based on the calculated NOAEL > 2460 mg/kg bw/day for dibismuth trisulfide.
Considering the appropriate assessment factors, the consumer DNEL (long-term dermal exposure) is calculated as follows:
Correction of the dose descriptor:
Dose descriptor of relevant study: > 24600 mg/kg bw/day (NOAEL x 10; assuming 10 % dermal absorption)
Assessment factor for exposure duration (subacute to chronic): 6
Allometric scaling factor (rat to human): 4
Assessment factor for other interspecies differences: 2.5
Assessment factor for intraspecies differences (consumer): 10
Taking the above mentioned assessment factors into account, the following consumer DNEL is:
Consumer DNEL (dermal exposure) = 24600 mg/kg bw/day / (1 x 6 x 4 x 2.5 x 10 x 1 x 1) = 24600 / 600 = 41 mg/kg bw/day
Oral exposure
A subchronic and a subacute repeated dose toxicity test with dibismuth trisulfide is not available. Consequently, read-across was applied using study results from bismuth in order to derive the consumer DNEL (long-term oral exposure). A 28-day repeated dose oral toxicity study with bismuth revealed a NOAEL > 1000 mg Bismuth/kg bw/day. The DNEL derivation is based on the calculated NOAEL > 2460 mg/kg bw/day for dibismuth trisulfide.

Taking the above mentioned assessment factors into account, the following consumer DNEL is:
Consumer DNEL (dermal exposure) = 2460 mg/kg bw/day / (1 x 6 x 4 x 2.5 x 10 x 1 x 1) = 2460 / 600 = 4.1 mg/kg bw/day
Acute/ short term exposure- systemic effect
Inhalation
There is no indication for acute systemic toxicity of dibismuth trisulfide. The substance is not classified for inhalation toxicity. Moreover, due to its strong adhesive properties dibismuth trisulfide particles agglomerate and deposit. The vapour pressure is negligible. Taken together, its physicochemical properties exclude inhalative exposure. Also no peak exposure is expected. Therefore no DNEL is required.
Dermal
In an acute dermal toxicity study with dibismuth trisulfide according EU method B.3 and OECD 402, a LD50 value of > 2000 mg/kg bw was obtained. Thus, the test material is not classified and labelled for acute dermal toxicity, according to Directive 67/548/EEC (DSD) and Regulation (EC) No 1272/2008 (CLP). Therefore no DNEL was derived.
Oral
There is no indication for acute systemic toxicity of dibismuth trisulfide. Based on the physical form and low water solubility, but mainly on the absence of toxicity in acute and repeated dose oral toxicity studies, oral absorption of dibismuth trisulfide is assumed to be very low. This conclusion is confirmed by the literature on oral absorption of insoluble bismuth compounds. Therefore no DNEL is derived.
Acute and long term exposure- local effect
Respiratory irritation
Due to its strong adhesive properties dibismuth trisulfide particles agglomerate and deposit. The vapour pressure is negligible. Taken together, its physicochemical properties exclude inhalative exposure. Moreover, there is no indication for any adverse local effects as the substance is neither classified for inhalation toxicity nor for irritation/corrosion according to Directive 67/548/EEC (DSD) and Regulation (EC) No 1272/2008 (CLP). Therefore no DNEL is required.
Skin irritation
The test item is not classified for skin irritation/corrosion and skin sensitization according to Directive 67/548/EEC (DSD) and Regulation (EC) No 1272/2008 (CLP). Therefore no DNEL was derived.
Eye irritation
The test item is not classified for eye irritation according to Regulation (EC) No 1272/2008 (CLP) and Directive 67/548/EEC (DSD).
