10.Stability and reactivity 10.1 Reactivity

no data available

10.2 Chemical stability

Study has been undertaken to determine the stability of four benzodiazepines: clonazepam, midazolam, flunitrazepam & oxazepam in whole blood samples. Spiked blood was stored at four different temperatures (room temperature, 4 degrees C, -20 degrees C & -80 degrees C) & analysed at selected times during 1 yr. Determination was performed on the first, third & seventh day during the first wk, then once/wk for 3 wk, once every 2 wk for 4 wk, then once/month for 4 months & finally, once every 2 months. Extraction was performed using liquid-liquid extraction with 1-chlorobutane, while quantification was carried out using high performance liquid chromatography equipped with a photodiode-array ultraviolet detector. At room temperature, the concn of all benzodiazepines decreased over 1 yr to 100 & 70% for low & high concns, respectively. At 4°C, the decr was between 90 & 100% for low concns & between 50 & 80% for high concns. At -20°C, the measured decr was between 10 & 20% for high & low concns, respectively. At -80°C, the measured loss was not significant at high concn except for midazolam. However, at low concn the determined decr was between 5 & 12%. The data collected suggests that quantitative results concerning long-term stored samples should be interpreted with caution in forensic cases. Further investigations concerning the stability of drugs in whole blood or other biological samples, additional methods of identification & determination as well as the establishment of optimal storage conditions should be undertaken in forensic cases.

12.2 Persistence and degradability

Biodegradation data in soil or water were not available. (SRC, 2013)

12.3 Bioaccumulative potential

An estimated BCF of 11 was calculated in fish for flunitrazepam(SRC), using an estimated log Kow of 2.06(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).

12.4 Mobility in soil

The Koc of flunitrazepam is estimated as 170(SRC), using a log Kow of 2.06(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that flunitrazepam is expected to have moderate mobility in soil.

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.

Contaminated packaging

Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
