Indication of any immediate medical attention and special treatment needed

Basic treatment: Establish a patent airway. Suction if necessary. Watch for signs of respiratory insufficiency and assist ventilations if needed. Administer oxygen by nonrebreather mask at 10 to 15 L/min. Monitor for pulmonary edema and treat if necessary . Monitor for shock and treat if necessary . Anticipate seizures and treat if necessary . For eye contamination, flush eyes immediately with water. Irrigate each eye continuously with normal saline during transport . Do not use emetics.

Persistence and degradability

AEROBIC: Diethyl ((diethanolamino)methyl) phosphonate at concentrations of 10 and 20 mg/L was found to biodegrade 15 and 19%, respectively, after 28 days in a modified Sturm test using activated sludge from a municipal sewage treatment plant(1).[(1) US EPA; High Production Volume (HPV) Challenge Program.

Bioaccumulative potential

An estimated BCF of 3.2 was calculated for diethyl ((diethanolamino)methyl) phosphonate(SRC), using a log Kow of -0.72(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).[(1) US EPA; High Production Volume (HPV) Challenge Program.

Mobility in soil

The Koc of diethyl ((diethanolamino)methyl) phosphonate is estimated as 9.7(SRC), using a log Kow of -0.72(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that diethyl ((diethanolamino)methyl) phosphonate is expected to have very high mobility in soil. However, the estimated pKa of diethyl ((diethanolamino)methyl) phosphonate is 5.6(4), indicating that this compound is expected to partially exist in the protonated form in the environment, and cations generally adsorb to organic carbon and clay more strongly than their neutral counterparts(5).[(1) US EPA; High Production Volume (HPV) Challenge Program.
