“…Another option is to replace lead with a manganese fuel additive such as methylcyclopentadienylmanganese tricarbonyl (MMT), that has similar antiknock and octane number-boosting properties. Studies with this manganese fuel additive at the recommended use level of 0.125 g Mn/gal (33 mg/L) gave exhaust emission particles with mass median diameter of 0.2-0.4 ,um (46). Manganese was emitted as MnO.…”

Metallic elements contained in coal, oil and gasoline are mobilized by combustion processes and may be emitted into the atmosphere, mainly as components of submicron particles. The information about the amounts, composition and form of metal compounds is reviewed for some fuels and combustion processes. Since metal compounds are always contained in urban air pollutants, they have to be considered whenever an evaluation of biological impact of air pollutants is made. The value of currently used bioassays for the evaluation of the role of trace metal compounds, either as major biologically active components or as modifiers of biological effects of organic compounds is assessed. The whole animal bioassays for carcinogenicity do not seem to be an appropriate approach. They are costly, time-consuming and not easily amenable to the testing of complex mixtures. Some problems related to the application and interpretation of short-term bioassays are considered, and the usefulness of such bioassays for the evaluation of trace metal components contained in complex air pollution mixtures is examined.

“…These catalysts, designed to remove NO, CO, and hydrocarbons simultaneously, are intrinsically much more prone to poisoning (1). In these laboratory experiments we were not concerned with catalyst deactivation by physical causes (plugging of catalyst pores and channels), which is an intrinsic problem associated with the deposits derived from MMT, even at lower concentrations (2,8).…”

“…Below this concentration, the rate constant was constant at 0.14/hr. Faggon et al (38) estimated that the maximum contribution to airborne manganese from use of MMT would be 0.05 mg/m3. A chronic inhalation study with rats and squirrel monkeys at exposure levels of 10, 100, and 1000 mg/m3 for 22 hr/day, 7 days/week, has been reported by Ulrich and Van Petten (45).…”

Emission control devices are installed to meet the exhaust standards of the Clean Air Act for carbon monoxide and hydrocarbons, and it is necessary to know, from a public health point of view, how exhaust emissions may be affected by changes in fuel additives and fuel composition. Since these topics are concerned with developing technologies, the available literature on exhaust emission characteristics and the limited information on health effects, is reviewed.
