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

Human exposure to second-generation and indandione anticoagulants produces symptoms consistent with anticoagulation effects (e.g., hematomas, hematemesis, hematuria, easy bruisability). Treatment of cases of exposure, particularly of substantial and repeated exposure, may require vitamin K1 therapy and monitoring of prothrombin times for periods of many months.

Safety glasses with side-shields conforming to EN166. Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU).

Skin protection

Wear impervious clothing. The type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace. Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique(without touching glove's outer surface) to avoid skin contact with this product. Dispose of contaminated gloves after use in accordance with applicable laws and good laboratory practices. Wash and dry hands. The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from it.

12.2 Persistence and degradability

AEROBIC: Relevant biodegradation screening tests available for difenacoum include four ready biodegradability tests and one inherent biodegradability test(1). The four ready biodegradability tests were performed according to OECD 301B, 301D, and 301F guidelines with CO2 evolution, dissolved oxygen, and oxygen consumption as test parameters, respectively, with sludge from sewage treatment used as inoculum(1). Initial test substance concentration was between 2 and 100 mg/L in the experiments(1). Incubation period was 28 days and the degree of degradation was between 0% and 31%, which is below the ready biodegradability pass levels of 60% or 70%(1). An inherent biodegradation test was conducted according to an OECD 302D draft guideline (OECD 2001) with CO2 evolution as test parameter and adapted sewage sludge as inoculum(1); the degradation was 3% after 56 days incubation, indicating that difenacoum is not inherently biodegradable(1). An aerobic soil half-life of 439 days has been reported(2).

12.3 Bioaccumulative potential

An estimated BCF of 6580 was calculated in fish for difenacoum(SRC), using an estimated log Kow of 7.62(1) and a regression-derived equation(1). According to a classification scheme(2), this BCF suggests the potential for bioconcentration in aquatic organisms is very high(SRC), provided the compound is not metabolized by the organism(SRC).

12.4 Mobility in soil

Using a structure estimation method based on molecular connectivity indices(1), the Koc of difenacoum can be estimated to be 4.8X10+6(SRC). According to a classification scheme(2), this estimated Koc value suggests that difenacoum is expected to be immobile in soil. The pKa of difenacoum is 4.84(3), indicating that this compound will exist partially in anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4). Using an HPLC approximation method (OECD 121), difenacoum was found to have a Koc value of 4.27X10+5 at pH 3-4 and a Koc range of 17-165 at pH 7-8.5(3); however, this method was considered unsuitable for difenacoum because it did not use measurements in real soil(3). It does suggest that lower adsorption may occur in neutral or alkaline soils(3). The low mobility of difenacoum in soil is supported by results of soil column leaching studies(3).

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.
