Carcinogenicity

The Human Health Assessment Group in EPA's Office of Health and Environmental Assessment has evaluated diethylstilbestrol for carcinogenicity. According to their analysis, the weight-of-evidence for diethylstilbestrol is group A, which is based on sufficient evidence in humans and sufficient evidence in animals. As a group A chemical, diethylstilbestrol is considered carcinogenic to humans.

12.Ecological information

12.1 Toxicity

• Toxicity to fish: no data available
• Toxicity to daphnia and other aquatic invertebrates: no data available
• Toxicity to algae: no data available
• Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: Over a period of 6 days under aerobic conditions at 20°C, 500 mg/l diethylstilbestrol was resistant to biodegradation in two activated sludge samples and was slightly inhibitory in a third sample(1). Biodegradation studies of diethylstilbestrol have indicated this hormone is persistant in soil and feces(2).

12.3 Bioaccumulative potential

An estimated BCF of 1600 was calculated for diethylstilbestrol(SRC), using a log Kow of 5.07(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is very high if diethylstilbestrol is not metabolized.

12.4 Mobility in soil

Using a structure estimation method based on molecular connectivity indices(1), the Koc for diethylstilbestrol can be estimated to be 570,000(SRC). According to a classification scheme(2), this estimated Koc value suggests that diethylstilbestrol 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.
