6.Accidental release measures

6.1 Personal precautions, protective equipment and emergency procedures

Use personal protective equipment. Avoid dust formation. Avoid breathing vapours, mist or gas. Ensure adequate ventilation. Evacuate personnel to safe areas. Avoid breathing dust. For personal protection see section 8.

6.2 Environmental precautions

Prevent further leakage or spillage if safe to do so. Do not let product enter drains. Discharge into the environment must be avoided.

6.3 Methods and materials for containment and cleaning up

AEROBIC: In a 5-day incubation study using an activated sludge seed from a municipal sewage treatment plant, 28.0% of initial 1-hexadecanol was mineralized (CO2 measurement)(1). A theoretical BOD of 0% was observed using the AFNOR (the French norm procedure) screening test and a 5-day incubation period(2). In standard 5-day BOD tests using emulsified 1-hexadecanol, 30-60% of initial 1-hexadecanol was oxidized(3). In studies designed to examine the biodegradability of 1-hexadecanol in thin films (monolayer) on water surfaces, it was found that biological destruction of the monolayer resulted in measurable consumption of the material with all substrates that were tested; substrates included 2% settled domestic sewage in BOD dilution water, 50% Ohio River water + 50% BOD dilution water, water from a stock pond near San Antonio, TX, and other combinations of BOD dilution water and mineral supplements; oxidation rates varied with substrates; oxidation rates varied from 6.2 to 14.3% over incubation periods of 20 to 48 days(3). In Warburg respirometer tests using activated sludge and 500 mg/L of 1-hexadecanol (well above its aqueous solubility), the theoretical oxygen demand was only 0.4% after a 12-hr incubation period(4). In static culture tests examining the disappearance of 1-hexadecanol in seeded media as compared to unseeded control media over a 10-day incubation period, almost none disappeared from the control media while nearly 20% disappeared from the seeded media; in shake flask tests using seeded media and a fine granular form of 1-hexadecanol, the initial 1-hexadecanol concn of 100 mg/L decreased to only 0.25 mg/L after 30 days of incubation; the overall results of the study concluded that given sufficient time in contact with adapted microbial species under conditions otherwise non-limiting, the complete disappearance of 1-hexadecanol as an identifiable molecular species will occur; one limiting condition is the relative insolubility of 1-hexadecanol in water; it was found that microbial growth occurs more rapidly when the 1-hexadecanol substrate is added in dissolved form (eg hexane solution)(5).

7.Handling and storage

7.1 Precautions for safe handling

Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Avoid exposure - obtain special instructions before use.Provide appropriate exhaust ventilation at places where dust is formed. For precautions see section 2.2.

7.2 Conditions for safe storage, including any incompatibilities

In general, materials which are toxic as stored or which can decompose into toxic components ... should be stored in a cool, well-ventilated place, out of direct rays of the sun, away from areas of high fire hazard, and should be periodically inspected ... incompatible materials should be isolated from each other.

12.2 Persistence and degradability

AEROBIC: In a 5-day incubation study using an activated sludge seed from a municipal sewage treatment plant, 28.0% of initial 1-hexadecanol was mineralized (CO2 measurement)(1). A theoretical BOD of 0% was observed using the AFNOR (the French norm procedure) screening test and a 5-day incubation period(2). In standard 5-day BOD tests using emulsified 1-hexadecanol, 30-60% of initial 1-hexadecanol was oxidized(3). In studies designed to examine the biodegradability of 1-hexadecanol in thin films (monolayer) on water surfaces, it was found that biological destruction of the monolayer resulted in measurable consumption of the material with all substrates that were tested; substrates included 2% settled domestic sewage in BOD dilution water, 50% Ohio River water + 50% BOD dilution water, water from a stock pond near San Antonio, TX, and other combinations of BOD dilution water and mineral supplements; oxidation rates varied with substrates; oxidation rates varied from 6.2 to 14.3% over incubation periods of 20 to 48 days(3). In Warburg respirometer tests using activated sludge and 500 mg/L of 1-hexadecanol (well above its aqueous solubility), the theoretical oxygen demand was only 0.4% after a 12-hr incubation period(4). In static culture tests examining the disappearance of 1-hexadecanol in seeded media as compared to unseeded control media over a 10-day incubation period, almost none disappeared from the control media while nearly 20% disappeared from the seeded media; in shake flask tests using seeded media and a fine granular form of 1-hexadecanol, the initial 1-hexadecanol concn of 100 mg/L decreased to only 0.25 mg/L after 30 days of incubation; the overall results of the study concluded that given sufficient time in contact with adapted microbial species under conditions otherwise non-limiting, the complete disappearance of 1-hexadecanol as an identifiable molecular species will occur; one limiting condition is the relative insolubility of 1-hexadecanol in water; it was found that microbial growth occurs more rapidly when the 1-hexadecanol substrate is added in dissolved form (eg hexane solution)(5).

12.3 Bioaccumulative potential

In a 3-day static exposure study using golden orfe fish (Leuciscus idus melanotus), a 1-hexadecanol bioconcentration factor (BCF) of 56 was observed(1). According to a classification scheme(2), this BCF suggests the potential for bioconcentration in aquatic organisms is moderate(SRC), provided the compound is not metabolized by the organism(SRC). A 24-hr BCF of 17000 was observed in algae (Chlorella fusca)(1).

12.4 Mobility in soil

The Koc of 1-hexadecanol is estimated as 25,000(SRC), using a water solubility of 4.122X10-2(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that 1-hexadecanol is expected to be immobile 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.
