How to dilute acetic acid and acetic acid diluted laboratory liquid generally default to volume ratio, the proportion of 30% by volume of glacial acetic acid and water for 3 to 7, (because you buy a stock concentration of glacial acetic acid was 99.5%, can be short-sighted to 100% , do not date.) At home operation, you can use the same container (eg glass), the first volume seven (7) of water into the container slightly larger (Note Each volume of the possible agreement, preferably every both times the amount of a full cup, and operator error is small), then the amount of 3 parts (3) of glacial acetic acid was poured into the same volume of liquid is slightly larger container, then mix well Acute toxicity: LD50: 3.3 g / kg (rat orally); 1060 mg / kg (rabbit percutaneous). LC50: 5620 ppm, glacial acetic acid, 1 h (mouse inhalation); 12.3 g / m3,1 h (rat inhalation). The person I 1.47 mg / kg, the lowest toxic dose, there gastrointestinal symptoms; the person 20 ~ 50 g, lethal dose. 80% of the concentration of acetic acid can cause severe burns in guinea pig skin and glacial acetic acid agents, 50% to 80% of the produce moderate to severe burns, is very slightly less than 50%, 5% to 16% concentration never burns. People can not be 2 ~ 3 g / m3 concentration tolerated than 3 min. Human oral lethal dose is 20 ~ 50 g. Subacute and chronic toxicity: This concentration is about 100 mg / m3 role in bringing workers with chronic nose, nasopharynx, eyelid and throat inflammation occurs, or even cause bronchitis. Inhalation (200 ~ 490) mg / m3 × (7 ~ 12) years, acetic acid prices, eyelid edema, conjunctival hyperemia, chronic pharyngitis, bronchitis and other symptoms. Mutagenicity: microbial mutagenicity: Escherichia coli 300 ppm (3 h). Sister chromatid exchange: human lymphocytes 5 mmol / L. Reproductive toxicity: rat poisoning by mouth lowest dose (TDL0): 700 mg / kg (18 d, acetic acid manufacturers, postpartum), neonatal rat behavior affected. In rat testis poisoning the lowest dose (TDL0): 400 mg / kg (1 d, male), the impact on male fertility index. Health Hazards: Pathways to inhaled, ingested, percutaneous absorption. After inhalation of the nose, throat and respiratory tract irritation. A strong eye irritation. Skin contact, light erythema, causing severe chemical burns. Wrongly concentrated acetic acid, mouth and digestive tract can produce erosion, severe cases can cause shock and death. Chronic effects: eyelid edema, conjunctival hyperemia, chronic pharyngitis and bronchitis. Long-term repeated exposure can cause skin drying, degreasing and dermatitis. Environmental hazards: hazard to the environment, can cause pollution of water bodies.
