are that "for MMT and its transformation products, when MMT is used as a fuel additive in petrol, no significant human health or environmental concerns related to exposure to either MMT or its transformation products (manganese phosphate, manganese sulfate and manganese tetroxide) were identified at use at levels up to 18 mg Mn/L. Depending on the regional needs and the vehicle emission control technology available, an MMT treat rate in the range of 8.3 mg Mn/L to 18 mg Mn/L is scientifically justified and may deliver both environmental and economic benefits without significant adverse effects."

NICNAS concluded that there is "low occupational risk associated with MMT" both "for workers involved in formulating and distributing LRP or aftermarket fuel additives and those involved in automotive maintenance". Further, they also concluded that there is a "low risk" to the public from the use of MMT.

determine a program for developing the necessary data to support a waiver application. In 1990, Ethyl filed its third waiver application prompting an extensive four-year review process. In 1993, the U.S. EPA determined that use of MMT at 8.3 mg Mn/L would not cause, or contribute to, vehicle emission control system failures.
878:), etc. The new CAA amendment required a "waiver" to allow use of fuel additives made of any elements other than carbon, hydrogen, oxygen (within certain limits) and nitrogen. To obtain a waiver, the applicant was required to demonstrate that the fuel additive would not lead to a failure of vehicle emission control systems.
990:. The US ATSDR (Agency for Toxic Substances and Disease Registry) notes that MMT is very unstable in light and degrades to a mixture of less harmful substances and inorganic manganese in less than 2 minutes. Therefore, human exposure to MMT prior to combustion in gasoline would not likely occur at significant levels.

Based on the low potential for the release of concentrated MMT (before its combustion in gasoline) under normal storage and use, as well as its rapid photo-degradation properties, it has been concluded in multiple technical and global regulatory assessments that significant impacts to human health or

The MMT dossier registered in the
European Chemical Agency's webpage indicates that before combustion in gasoline, MMT is classified as an acute toxicant by the oral, dermal, and inhalation routes of exposure under the European Union's Classification, Labeling and Packaging Regulation (EC/1272/2008),

In 2013, a risk assessment on MMT was developed by ARCADIS Consulting and verified by an independent panel, according to the methodology provided by the
European Commission in compliance with the requirements of the European Fuel Quality Directive (2009/30/EC). The conclusions of a risk assessment

Significant human or environmental exposures associated with manganese compounds (manganese phosphate, manganese sulfate and manganese dioxide) from the combustion of MMT are not expected. In Health Canada's risk assessment on the health implications of the manganese combustion products of MMT, it

concluded that "airborne manganese resulting from the combustion of MMT in gasoline powered vehicles is not entering the
Canadian environment in quantities or under conditions that may constitute a health risk" and confirmed they were taking no action with respect to MMT. Similarly, the 2003 NICNAS

The general public has minimal direct exposure to MMT. As stated by the US EPA in their risk assessment on MMT, "except for accidental or occupational contacts, exposure to MMT itself was not thought likely to pose a significant risk to the general population." Similarly, the

MMT has been used in
Canadian gasoline since 1976 (and in numerous other countries for many years) at a concentration up to 8.3 mg Mn/L (though the importation and interprovincial trade of gasoline containing MMT was restricted briefly during the period 1997–1998) and was introduced into

Ethyl
Corporation applied to the US EPA for a waiver for MMT in both 1978 and 1981; in both cases the applications were denied because of stated concerns that MMT might damage catalytic converters and increase hydrocarbon emissions. In 1988, Ethyl began a new series of discussions with the EPA to
888:
As a result of this ruling, Ethyl initiated a legal action claiming that the EPA had exceeded its authority by denying the waiver on these grounds. This was upheld by the US Court of
Appeals and EPA subsequently granted a waiver which allows the use of MMT in US unleaded gasoline (not including

The human and environmental health impacts that may result from the use of MMT will be a function of exposure to either: (1) MMT in its original, unchanged, chemical form and/or (2) manganese combustion products emitted from vehicles operating on gasoline containing MMT as an octane improver.

Additional health studies, overseen by the US EPA, were conducted to explain the transport of manganese in the body. In studies published from 2007 through 2011, no significant health effects are anticipated from the use of MMT in gasoline.
