What is TDI in medical terms?
Tolerable Daily Intake. Similar term(s): TDI. Definition: A TDI is an estimate of the amount of a substance in air, food or drinking water that can be taken in daily over a lifetime without appreciable health risk. The TDI short forTolerable Daily Intake specifies the quantity of a substance that can be consumed on a daily basis over an entire lifetime without an appreciable health risk.Tolerable Daily Intake. Similar term(s): TDI. Definition: A TDI is an estimate of the amount of a substance in air, food or drinking water that can be taken in daily over a lifetime without appreciable health risk. TDIs are calculated on the basis of laboratory toxicity data to which uncertainty factors are applied.
What is TDI disease?
Five respiratory reactions attributable to TDI are described with supporting evidence. The reactions are sensitization, irritation from overexposure, acute loss of ventilatory capacity, accelerated loss of pulmonary function and induction of a general asthmatic state.

What are the side effects of TDI?
Toluene diisocyanate is irritating to mucous membranes, skin, eyes, and the respiratory tract. Acute inhalation exposure may lead to euphoria, ataxia, mental aberrations, vomiting, abdominal pain, bronchospasm, chemical bronchitis, hypersensitivity pneumonitis, and noncardiogenic pulmonary edema. Toluene diisocyanate (TDI) pulmonary disease: Immunologic and inhalation challenge studies – Journal of Allergy and Clinical Immunology.Respiratory symptoms often reported in workers with TDI-induced asthma include wheezing, dyspnea, coughing, and chest tightness, which often persist after TDI exposure has ceased (Mapp et al.
What are the symptoms of TDI exposure?
Following inhalation exposure to toluene diisocyanate the symptoms may be delayed and may progress over a period of days. Symptoms include dry throat, chest tightness, shortness of breath, coughing and wheezing. Other effects include poor memory, incoordination, headache, anxiety and confusion. The main target organ of toluene-induced toxicity is the central nervous system (CNS). Toluene is also an irritant to the skin and mucous membranes. The acute toxic effects following inhalation of toluene are summarised in the table. Toluene vapours are irritating to the eyes, nose, throat, and respiratory tract.
What are the symptoms of TDI?
Respiratory effects, including a decrease in lung function, have been reported in workers exposed to TDI or MDI. Asthma and symptoms of asthma, such as wheezing and shortness of breath, have been observed in some individuals who are sensitive to the toxicity of TDI and MDI. Health effects TDI can burn the eyes and skin, it is toxic from both short term exposures and long term exposures. Single large inhaled doses can cause severe irritation of the respiratory, gastrointestinal, and central nervous systems. High levels can cause build up of fluids in the lungs, which could lead to death.
What does TDI stand for?
TDI stands for turbocharged direct injection which is a specific design of turbodiesel engines. TDI engines feature turbocharging and cylinder-direct fuel injections and are produced from the Volkswagen Group. TDI stands for Turbocharged Direct Injection. Direct injection is when fuel is sprayed directly into a car’s cylinder rather than delivered through an intake manifold. Direct injection diesel engines tend to be more efficient and produce less soot than older types of engines.On the other hand, TDI stands for Turbocharged Direct Injection. These are engines that also use turbocharging and direct injection, but with diesel fuel.TDI stands for Turbocharged Direct Injection. Direct injection is when fuel is sprayed directly into a car’s cylinder rather than delivered through an intake manifold. Direct injection diesel engines tend to be more efficient and produce less soot than older types of engines.TDI stands for “turbocharged direct injection” and is used by Audi to identify its powerful diesel engines. Combining turbocharging and direct injection enables both impressive performance and remarkable efficiency.TDI engines typically offer superior torque at lower RPMs and better fuel efficiency under sustained load, while GDI engines provide better power-to-weight ratios and more responsive acceleration.
