Diethyl zinc toxicity. Zinc is a chemical element with the symbol Zn and atomic number 30. Zinc is a slightly brittle metal at room temperature and has a silvery-greyish appearance when oxidation is removed. It is the first element in group 12 IIB of the periodic table.
In some respects zinc is chemically similar to magnesium. Both elements exhibit only one normal oxidation state 2 and the Zn 2 and Mg 2. Diethyl ether Wiki 1696894 Beilstein.

Only those codes applicable to the University of Maryland are listed Hazardous waste is any solid waste that either exhibits any of the characteristics of hazardous waste or is a listed EPA waste. In addition EPA Hazardous Waste Codes are also classified as acute and non-acute. P-listed codes and certain dioxin codes F020-F023 and F026-F028 are considered to be acute.

Materials listed below in quantities up to about 100 g or 100 ml at a time are suitable for disposal down the drain while flushing with excess.
Acute toxicity As summarized in the Cosmetic Ingredients. A recent study found diethyl phthalate DEP and diethylhexyl phthalate DEHP in e-liquids although the quantified levels in the studys sample were below phthalate exposure limits Oh and Shin 2015. DEP can be a solvent or plasticizer and is found in variety of consumer products including fragrances cosmetics and detergent.
Zinc is the 14th most common element in the human body and is essential for all living things. The average human body contains about 20 to 25 grams of zinc and normal dietary intake of zinc is about 15 milligram mg per day Refs. Homeostatic mechanisms in the body regulate zincs absorption distribution cellular uptake and excretion Ref.
Similarly any oxygen absorbed.
