Absorption, Distribution and Excretion

... The systemic exposure to 7-Acetyl-1,1,3,4,4,6-hexamethyl-1,2,3,4-tetrahydronaphthalene (AHTN) was determined ... in humans under simulated conditions of exposure. Ring 14C-labeled AHTN was applied in alcoholic solutions without occlusion to three male volunteers at concentrations approximating that which might be encountered in a typical cologne type product. After a 6-h period, all material was removed from the surface of the skin. Blood, feces and urine were collected over a 5-day period. For both materials, levels in blood and plasma were below limits of detection at all times. Based on excretion, primarily in the urine, the total absorbed dose was approximately 1% for AHTN. However, over the 5-day period, 14.5% of AHTN was recovered from the skin in dressings over the site of application indicating that a 'reservoir' had formed in the skin but the material in the reservoir was lost, by desquamation and/or by reverse absorption, and not available systemically. A mean of 24% (AHTN) was shown to evaporate under the conditions of exposure.

  • Toxicity to daphnia and other aquatic invertebrates: EC50 Daphnia magna /(Water flea)/ 0.244 mg/L/21 days; semistatic; Effect: reproduction
  • Toxicity to algae: no data available
  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: Tonalide, present at 30 mg/L, released 0% theoretical BOD in four weeks using an activated sludge inoculum at 100 mg/L and the Japanese MITI test(1). No oxidation occurred after 28 days using adapted industrial sludge with respirometric method(1). No CO2 was released after 28 days using a sealed vessel with activated sludge adapted for 8 weeks or using sewage effluent and a modified Strum test after 28 days(1). Tonalide was degraded 80% in 3 wks by the fungus Aureobasidium pollulans and was totally degraded in 6 days by Phanerochaete chrysosporium(1).

12.3 Bioaccumulative potential

An average BCF of 1,069 was given for eel (Anguilla anguilla) and 600 for zebra fish (Brachydonio rerio)(1). A BCF was given for bluegill sunfish (L. Macrochirus) as 597(2). According to a classification scheme(3), these BCF suggest the potential for bioconcentration in aquatic organisms is high to very high(SRC). Tonalide had a BCF of 50 in midge larvae (Chironomus riparius) and 6918 in worms (Lumbriculus variegatus)(4).

12.4 Mobility in soil

Measured Koc values for tonalide are 9,550 L/kg(1), 6,309 L/kg(2) and 63,000 L/kg(3). According to a classification scheme(4), these Koc value suggest that tonalide is expected to be immobile in soil(SRC).

12.5 Other adverse effects

no data available

13.Disposal considerations

13.1 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.
