Description

4,4'-Dichlorodiphenyltrichloroethane is a synthetic organochlorine insecticide. 4,4'-Dichlorodiphenyltrichloroethane functions by opening sodium ion channels in the insects’ neurons, causing them to fire spontaneously which in turn leads to death. 4,4'-Dichlorodiphenyltrichloroethane is banned for agricultural use in North America, it is still commonly used in some countries and particularly as a means of malaria control.

Excerpt from ERG Guide 151 [Substances - Toxic (Non-combustible)]: Highly toxic, may be fatal if inhaled, swallowed or absorbed through skin. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution. (ERG, 2016)

4.3 Indication of immediate medical attention and special treatment needed, if necessary

Observation. Persons exposed to high levels of organochlorine pesticides by any route should be observed for sensory disturbances, incoordination, speech slurring, mental aberrations, and involuntary motor activity that would warn of imminent convulsions. /Solid organochlorine insecticides/

5.Fire-fighting measures

5.1 Extinguishing media

Fire extinguishing agents: Water, foam, dry chemical, or carbon dioxide.

5.2 Specific hazards arising from the chemical

Excerpt from ERG Guide 151 [Substances - Toxic (Non-combustible)]: Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Containers may explode when heated. Runoff may pollute waterways. (ERG, 2016)

5.3 Special protective actions for fire-fighters

Wear self-contained breathing apparatus for firefighting if necessary.

6.Accidental release measures

6.1 Personal precautions, protective equipment and emergency procedures

6.2 Environmental precautions

Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Sweep spilled substance into covered sealable, non-metallic containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.

6.3 Methods and materials for containment and cleaning up

SRP: Wastewater from contaminant suppression, cleaning of protective clothing/equipment, or contaminated sites should be contained and evaluated for subject chemical or decomposition product concentrations. Concentrations shall be lower than applicable environmental discharge or disposal criteria. Alternatively, pretreatment and/or discharge to a POTW is acceptable only after review by the governing authority. Due consideration shall be given to remediation worker exposure (inhalation, dermal and ingestion) as well as fate during treatment, transfer and disposal. If it is not practicable to manage the chemical in this fashion, it must meet Hazardous Material Criteria for disposal.

7.Handling and storage

12.2 Persistence and degradability

DDT is biodegraded by a number of microorganisms isolated from water, sediments and soils(1,2). Biodegradation under environmental conditions has been shown to be quite variable, however, with a number of factors playing a role, especially the presence of anaerobic conditions and high populations of the required microorganisms(1,2). In certain flooded soils, DDT is readily degraded with complete degradation in one soil in approximately 31 days(3). Degradation has been demonstrated in soils under anaerobic conditions, while little or no degradation was observed under aerobic conditions(1,2,4). Various amendments to soils such as energy and carbon sources, were shown to increase degradation under anaerobic but not aerobic conditions(1,4,5). Reported half-lives for DDT in soils range from 2 years to > 15 years(6-9). Using a river-die away test, no change in DDT concentration was found in raw river water over a period of 8 weeks(10). DDT incubated in 6 lake water samples was converted to DDD (1,1'-bis(p-chlorophenyl)-2,2-dichloroethane), with greater conversion in samples with large amounts of plankton - up to 95% conversion in one sample(1). Six marine water samples showed poor metabolic activity with respect to DDT degradation(11). DDT degradation of up to 67% in sediments in up to 24 weeks has been reported(12). DDT is apparently co-metabolized by microorganisms and is not used as a sole carbon source(1). Products of biodegradation include DDD and DDE (1,1'-bis(p-chlorophenyl)-2,2-dichloroethylene); occasionally DBP (4,4'-dichlorobenzophenone) is formed appreciably(1,2).

12.3 Bioaccumulative potential

The following BCF values have been reported for aquatic organisms: 600 to 84,500, fish(1,2); 51,000 to 100,000, fathead minnows(3,4). Bioconcentration factors of 5,100-24,400 were measured for carp exposed to 1 ug/L of DDT over a 10 week incubation period and BCF values of 6,080-25,900 were measured for carp exposed to 0.1 ug/L(5). According to a classification scheme(6), these BCF values suggest bioconcentration in aquatic organisms is very high(SRC).

12.4 Mobility in soil

The Koc of DDT ranges from 1.13X10+5(1) to 3.5X10+5(2). According to a classification scheme(3), these Koc values suggest that DDT 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.

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.
