When looking at buying a replacement car we have several choices of engine. Petrol/LPG/Diesel/hybrid. Petrol and diesel are by far the most common and so more affordable.
Petrol engines tend to be more powerful at a lower engine size. Petrol, when burn't in an engine doesn't appear to have any short or medium term effects, other than the climate effects. Health Protection Agency: Toxological review of petrol, version 2 2007 covers this well.
Diesel engines appear to be more powerful and fuel efficient at any given engine size. However buring diesel in a car engine produces fumes such as carbon monoxide, aldehydes, oxides of nitogen and sulphurs and soot or particulates. See Health and safety Executives Report, Diesel engine exhaust emmisions 2007. These have been found to be detrimental to health causing lung and respiratory problems such as asthma and chronic bronchitis, and possibly cancer. See Health Effects of Disel Exhaust Emmisions: Sydborn et al European Respiratory Journal 2001Apr, 17(4):733-746.
So what do you buy?
