Indication of immediate medical attention and special treatment needed, if necessary
Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR if necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on the left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. Poisons A and B

Persistence and degradability
AEROBIC: Estrone exhibited approximately 38% mineralization in 33 days using 4 Mile Creek sediment, 56% mineralization in 33 days using Boulder Creek sediment, and up 90% mineralization using South Platte River sediments, Colorado. Sediments were collected downstream of local waste water treatment plants. Upstream sediments exhibited approximately 1, 1, and 1% mineralization, respectively(1). Estrone is biodegraded by sewage bacteria via ring cleavage, ultimately to carbon dioxide through a tricarboxylic acid cycle(2). C14-labeled estrone, present at 0.1 mg/kg, reached 2.0-17.4% mineralization in 21 days using natural German and Austrian soils in microcosm incubations maintained at 20 deg C(3,4). Soil-specific percent 14CO2 evolution values of 5.4, 4.6, 11.1, 2.0, and 17.4 were reported using Metelan (grassland, 3.3% SOC), Koeln (crop field, 0.7% SOC), Halle (crop field, 1.3% SOC), Gumpenstein (crop field, 2.2% SOC), and Hamapil (orchard, 1.5% SOC) soil microcosms, respectively(4).
Bioaccumulative potential
An estimated BCF of 54 was calculated in fish for estrone(SRC), using a log Kow of 3.13(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is moderate(SRC).
Mobility in soil
The Koc of estrone was reported as 2,000-18,000, using a Chelsea, MI topsoil (total organic carbon 5.45%)(1). Natural estrogens such as estrone are mainly removed from the aqueous phase by adsorption onto solids such as sludge in wastewater or soil in cases of land application(2). Sorption of estrone from CaCl2 solution and artificial urine in pastoral soils from North Island, New Zealand was studied. The log Koc values using Horotiu silt loam (pH 5.4; % OC 8.2; % Sand 34; % Silt 48; % Clay 17), Hamilton clay loam (pH 5.1; % OC 4; % Sand 19; % Silt 51; % Clay 30), and TeKowhai silt loam (pH 5.1; % OC 5; % Sand 9; % Silt 54; % Clay 37) were 2.66 and 2.75, 2.93 and 3.04, and 3.15 and 2.9, respectively(3), corresponding to Koc values of 457 and 562, 851 and 1096, and 1412 and 794, respectively(SRC). According to a classification scheme(4), these Koc values suggest that estrone mobility in soil is moderate to immobile. In soils with a long history of treatment with manure, biosolids, or wastewater, sorption of estrone becomes dependent on soil organic carbon content (SOC). Kd values of 122, 46, 134, 72, and 67 mL/g were reported using Metelan (grassland, SOC 3.3%), Koeln (crop field, 0.7% SOC), Halle (crop field, 1.3% SOC), Gumpenstein (crop field, 2.2% SOC), and Hamapil (orchard, 1.5% SOC) soils in Germany, respectively(5). A Kd of 402 L/kg was reported using activated sludge(6).

SECTION 13: Disposal considerations
Disposal methods
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.
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.
