It is the duty of the German Environment Agency air monitoring network to accomplish the German monitoring obligations, which result either from the signing of international agreemens (e.g. UN ECE Convention on long range transboundary air pollution) or from the EU legislation. Measuring programs, measurement parameters, measurement methods are specified and are developed by experts in international working groups.
There is no measurement need for the German Environmental Agency air monitoring network regarding the paramters (aluminium, barium, strontium) you mentioned.
SUCCES study 1996 (NASA)
IN (ice nucleating particles) sampled within aircraft exhaust and contrails had higher number fractions of metallic particles, which includes those rich in Zn, Al and Ti than the IN sampled in air that was not immediately affected by aircraft exhaust.

Atmospheric Aerosol Properties and Climate Impact
U.S. Climate Change Science Program 2009
Changes in cloud cover, in cloud vertical development, and cloud optical properties will have strong radiative and therefore, climatic impacts. Furthermore, factors that change cloud development will also change precipitation processes. These changes may alter amounts, locations and intensities of local and regional rain and snowfall, creating droughts, floods and severe weather.
Inadvertent climate modification due to anthropogenic lead
in: Nature Geoscience, April 2009
Aerosol particles can interact with water vapour in the atmosphere, facilitating the condensation of water and the
formation of clouds. At temperatures below 273 K, a fraction
of atmospheric particles act as sites for ice-crystal formation.
Atmospheric ice crystals—which are incorporated into clouds
that cover more than a third of the globe are thought
to initiate most of the terrestrial precipitation
Stratospheric Welsbach Seeding for Reduction of Global Warming 1990
One proposed solution to the problem of global warming involves the seeding of the atmosphere with metallic particles.
One technique proposed to seed the metallic particles was to add the tiny particlesto the fuel of jet airliners, so that the particles would be emitted from jet engine exhaust while the airliner was at its crusing altitude.
System and Method of Control of the Terrestrial Climate and its Protection against Warming and Climatic Catastrophes Caused by Warming such as Hurricanes 2009
This system of the control and protection of the terrestrial climate relies mainly on civilian airlines burning (preferably price-subsidized) sun-shading (sun-blocking/sun-reflective) fuels in the high levels of the atmosphere in order to reduce the intensity of the solar radiation reaching the Earth's surface. The use of sun-blocking airline fuels for the protection of the Earth from solar radiation parallels the use of sun-blocking skin-creams for the protection of the individual.
Global Warming and Ice Ages: I. Prospects for Physics-Based Modulation of Global Change
Edward Teller, L. Wood, R. Hyde
The potential economic impacts of such limitations are obviously large: ≥$10 Billions/year. We propose that for far smaller — <1% —costs, the mean thermal effects of "greenhouse gases" may be obviated in any of several distinct ways, some of them novel. These suggestions are all based on scatterers that prevent a small
fraction of solar radiation from reaching all or part of the Earth.
Non-technical Briefing Notes for a Workshop At the Council on Foreign Relations Washington DC, May 05, 2008
This workshop will focus on the question of strategies for constraining and shaping geoengineering. We will explore formal, legal strategies as well as informal efforts to create norms that could govern testing and deployment of geoengineering systems and their possible undesirable consequences.
Benefits, risks, and costs of stratospheric geoengineering 2009
Anthropogenic stratospheric aerosol injection would cool the planet, stop the melting of sea ice and land-based glaciers, slow sea level rise, and increase the terrestrial carbon sink, but produce regional drought, ozone depletion, less sunlight for solar power, and make skies less blue. Furthermore it would hamper Earth based optical astronomy, do nothing to stop ocean acidification, and present many ethical and moral issues.

ENGINEERING THE CLIMATE: RESEARCH NEEDS AND STRATEGIES FOR INTERNATIONAL COORDINATION

The Regulation of Geoengineering
Fifth Report of Session 2009–10
Future Topic Geoengineering 2012
Planungsamt der Bundeswehr, Dezernat Zukunftsanalyse (Future Analysis of the German armed forces on Geoengineering)
It is the international law, which is decisive for the legal assessment of the implementation of Geoengineering, due to its potential global side effects. But there is neither a binding definition (about Geoengineering) nor a direct regulation or even less a prohibition by now.
