Since phenol is absorbed through the skin relatively quickly, systemic poisoning can occur in addition to the local caustic burns. [51] Resorptive poisoning by a large quantity of phenol can occur even with only a small area of skin, rapidly leading to paralysis of the central nervous system and a severe drop in body temperature.
Synthesis of DNP (right) from phenol and nitric acid via 2-Nitrophenol and 4-Nitrophenol. DNP has the chemical formula HOC 6 H 3 (NO 2) 2. As a solid, it is a yellow, crystalline and has a sweet, musty odor. [1] [2] It sublimates, is volatile with steam, and is soluble in most organic solvents as well as aqueous alkaline solutions. [2]
Methanol toxicity (also methanol poisoning) is poisoning from methanol, characteristically via ingestion. [1] Symptoms may include an altered/decreased level of consciousness, poor or no coordination, vomiting, abdominal pain, and a specific smell on the breath. [1] [2] Decreased vision may start as early as twelve hours after exposure. [2]
Later symptoms include dizziness, vomiting, severe abdominal pain and diarrhoea. Severe cases may lead to fast, shallow breathing, then coma and convulsions. Patients may be given dialysis.
Symptoms of dinitro-ortho-cresol poisoning, due to ingestion or other forms of exposure, include confusion, fever, headache, shortness of breath, and sweating. [ 8 ] References
Toxic encephalopathy is a neurologic disorder caused by exposure to neurotoxic organic solvents such as toluene, following exposure to heavy metals such as manganese, as a side effect of melarsoprol treatment for African trypanosomiasis, adverse effects to prescription drugs, or exposure to extreme concentrations of any natural toxin such as cyanotoxins found in shellfish or freshwater ...
Common symptoms are often flulike and include headache, dizziness, upset stomach, chest pain or confusion, but highly concentrated levels of CO can cause a person to pass out without feeling symptoms.
What are the symptoms of carbon monoxide poisoning? In high concentrations, it can be deadly. The acute effects arise from carboxyhemoglobin formation in the blood, which hampers oxygen absorption.
