They precipitate calcium from the bloodstream causing violent Emergency Overview: muscular stimulation, convulsions, collapse, and death. Primary Routes of Exposure:Ingestion, Inhalation of dust. Eye Contact:May cause moderate to severe irritation of the eyes. Skin Contact:May cause moderate to severe irritation of the skin. Inhalation:Dust may be severely irritating to the nose, mucous membranes and respiratory tract. Harmful if swallowed. Ingestion may cause vomiting, pain, violent muscular stimulation, convulsions, collapse Ingestion: and death. Soluble oxalates remove calcium from the bloodstream. This interferes with the central nervous system Acute Health Affects: causing violent convulsions and death. Prolonged exposure to oxalates can lead to kidney failure resulting from calcium oxalate precipitation in renal Chronic Health Affects: tubes NTP:No IARC:No OSHA:No SECTION 4: First Aid Measures Immediately flush the eyes with copious amounts of water for at least 10-15 minutes. A victim may need Eye Exposure: assistance in keeping their eye lids open. Get immediate medical attention. Wash the affected area with water. Remove contaminated clothes if necessary. Seek medical assistance if Skin Exposure: irritation persists. Remove the victim to fresh air. Closely monitor the victim for signs of respiratory problems, such as difficulty Inhalation: in breathing, coughing, wheezing, or pain. In such cases seek immediate medical assistance. Antidotes are said to be soluble calcium given orally, and calcium gluconate given intravenously, to be Ingestion: administered by trained medical personnel. Keep the victim calm. Give the victim water (only if conscious).

制备

将0.3g Y(NO3)3溶于200mL水中，加入2mL 6mol/L的硝酸，然后加入40mL溶有3g草酸甲酯的水溶液。充分混合后，回流3h，即析出草酸盐沉淀。室温放置过夜再进行过滤，依次用水、乙醇和乙醚洗涤，生成结晶在室温风干，得九水合物。
