Organic solvent in the production of enterprises by the regular use, some of the use is also very large, so staff will often come into contact with organic solvent or contain in the machine solvent substances, what toxicity do these organic solvents have? Is it harmful to human health? With the help of alcohol recycling plant owner Gershon,solvent recovery equipment:
Organic solvents have the following toxicity:
1. Skin mucous membrane stimulation: most organic solvents have different degrees of stimulation to the skin mucous membrane, but mainly ketones and esters. May cause respiratory inflammation, contact and allergic dermatitis, bronchial asthma, eczema, conjunctivitis and so on.
2. Blood toxicity: Aromatic hydrocarbons, especially benzene, are the most common. Benzene reaches certain dose to be able to inhibit bone marrow hematopoietic function, often have leukopenia first, later thrombocytopenia, finally red blood cell reduction, become pancytopenia. Individual contact benzene sensitive person, can produce leukaemia.
3. Hepatorenal toxicity: more commonly seen in chlorine organic solvents, such as trichloroethylene, tetrachloroethylene, chloroform, carbon tetrachloride, trichloropropane, dichloroethane poisoning. The pathological changes of toxic hepatitis are fatty liver and hepatocyte necrosis. Clinical can have liver area to ache, emaciate, liver is splenomegaly, anorexia, weak, liver function is abnormal wait for expression. The renal damage caused by organic solvent is mostly tubular, with proteinuria and progressive decline in renal function.
4. Neurotoxicity: Chlorinated hydrocarbons (trichloroethylene, dichloromethane), aliphatic hydrocarbons (n-hexane, pentane, gasoline), aromatic hydrocarbons (benzene, styrene, butyltoluene, vinyl toluene), carbon disulfide, triclosan phosphate and other solvents with strong lipid solubility are most common.
There are roughly three types of damage to the nervous system caused by organic solvents. The second type is toxic encephalopathy, which is relatively rare and can be seen in severe acute and chronic poisoning caused by organic solvents such as carbon disulfide, benzene and gasoline. The third is toxic peripheral neuritis. Most of them are sensory type, followed by mixed type. Limb numbness, sensory decline, tingling, limb weakness, muscle atrophy and other manifestations; The first is toxic neurasthenia and vegetative nerve dysfunction. The patient can have giddy, have a headache, insomnia, much dream, somnolence, weak, memory drops, inappetency, angular, and much sweat, mood is unstable, heart rate is accelerated or decelerate, blood pressure fluctuates, skin temperature drops or bilateral limb temperature is asymmetric wait for a performance.
Now that you've learned about the toxicity of organic solvents, especially for people who have been exposed to organic solvents, do you know how to deal with them?This article links: /news/526.html
