SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.

In the present study, /hydroxyethyl carbamate/ HEC was synthesized by reacting ethylene carbonate with ammonia and was characterized. A single dose of HEC or /ethyl carbamate/ EC in saline was injected i.p. into adult male strain A mice, which were maintained for 16 weeks. HEC doses of 1.12, 4.6 and 11.2 mmol/kg induced 0.16, 0.32 and 0.32 lung adenomas/mouse, respectively. The 28% tumor incidence for the two highest doses was significantly (P < 0.05) greater than that in controls injected with saline alone. The number of tumors/mouse with 4.6 mmol HEC/kg was one-fortieth of that for an equimolar dose of EC. The weak activity of HEC supports the view that HEC is not a proximal carcinogenic metabolite of EC, i.e. that vinyl carbamate is produced directly from EC.

The carbamates alone weakly activated estrogen- or progesterone-responsive reporter genes in breast and endometrial cancer cells. All of the carbamates decreased estradiol- or progesterone-induced reporter gene activity in the breast and endometrial cancer cells. In whole cell competition binding assays, the carbamates demonstrated a limited capacity to displace radiolabeled estrogen or progesterone from /estrogen receptor/ or /progesterone receptor/. /Carbamates/

When human liver microsomes were incubated with NADPH and ethyl carbamate, the products vinyl carbamate, 2-hydroxyethyl carbamate, and ethyl N-hydroxycarbamate were detected. When the reaction was done with ethyl carbamate as the substrate, the rate of product formation was nearly first order in ethyl carbamate concentration (Km greater than 2 mM) and the rate was considerably slower than in the case of vinyl carbamate. ... A large kinetic deuterium isotope effect (greater than 7) was observed for the formation of 1,N6-ethenoadenosine from ethyl carbamate, and high isotope effects (6-8) were also noted for the formation of vinyl carbamate and 2-hydroxyethyl carbamate.
