Atmospheric particles, or particulate matter, can be solid or liquid with diameters varying from around 0.002[micrometers] to roughly 100[micrometers]. Atmospheric aerosol sources can be classified as primary or secondary, with the primary aerosol being directly emitted from the corresponding sources and the secondary particles being formed in the atmosphere, for example, from gas-phase chemical reactions that produce condensable vapors. At the same time aerosol particles are ultimately connected with the formation of water droplets and equivalently with the formation of clouds and fogs in the atmosphere.

With the reduction of material costs electroncos, many scientific instruments today you can make yourself at low cost.

Some examples of analytical instruments appear in the Journal of Chemical Education . There are also programs of UNESCO for scientific education in developing countries such as the low cost pH meter .
In Asia there are also some interesting developments like this photometer . Or that other in Brazil.

The Bureau of Land Management (BLM) manages 8.4 million acres of public lands in Colorado. These lands are managed for a multitude of uses including, but not limited to, recreation, energy production, mining, wildlife habitat and livestock grazing. Along with these 8.4 million acres, BLM Colorado oversees 27.3 million subsurface acres for mineral development. BLM Colorado employees are working hard with our partners, stakeholders, customers, elected officials, and the general public to restore and maintain the health of Colorado's public lands.
