Question

Given what we have learned to date regarding hydrocarbons, aerosols, and the ambient air environment, consider the textbook discussion in Chapter 6 regarding painted substrates of automobiles and structures.
Oilfield companies are known for keeping a well-serviced fleet of trucks for their staff employees, including often replacing these trucks for aesthetic purposes in order to maintain a strong marketing position within their competitive marketplace of client oil and gas producers. One of the most notable deteriorations in oilfield service vehicles (with relatively little age and mileage) is the exterior paint coating of the vehicle. What air pollutants might be responsible for the deterioration of the vehicle paint color, luster, and integrity? Carefully explain your answer from a chemical perspective.discuss on a short paragraph

Answer 1

The explanation is given as below:-

Air pollution induced by automobile exhaust fumes seems to be involved in increased cardiovascular and respiratory morbidity. The effects of inhalation of such pollutant gases on platelet function and blood viscosity have not been sufficiently investigated, even if these parameters seem to be in strict correlation with cardiovascular function. Twelve healthy non-smoking volunteers were exposed for 30 minutes in a closed room to air polluted by automobile fumes. Platelet aggregation, blood viscosity, HbCO levels and P50 STD were determined before and after exposure. Cardiovascular parameters (blood pressure, heart rate and ECG) were also measured. At the end of the test, HbCO levels were significantly increased, but P50 STD was significantly reduced; an impairment of both platelet function and blood viscosity was observed. No significant changes in cardiovascular parameters were recorded. The decreases in platelet aggregation and blood viscosity were not directly correlated with either the increase in carbon monoxide levels or with the reduced P50 STD levels. It can be reasonably concluded that gasoline exhaust fumes could have been responsible for the observed alterations.
