The mercury is rising in more ways than one. As our planet warms, wildfires such as the recent blazes in California are expected to become more common. And, a recent study shows, such fires are a major source of mercury emissions.
The map at left shows the annual average (in metric tons) of mercury, a toxic metal, released into the atmosphere by fires. The estimates are based on fires from 2002 to 2006.
Scientists at the National Center for Atmospheric Research in Boulder, Colorado, calculate that fires in the continental U.S. and Alaska release about 44 tons of mercury every year. Industrial sources such as power plants and incinerators release about 108 tons.
Leaves and ground litter absorb mercury from the atmosphere. When a fire breaks out, the stored mercury is released back into the atmosphere. It is particularly dangerous if it ends up in rivers and lakes, where it can be taken up by fish. Pregnant women and children are discouraged from eating some types of fish because of high mercury levels, which can cause neurological and development problems such as attention and language deficits.—Dawn Stover

Could the rise in mercury levels account for the rise in Autism?

Fires in high-latitude forests and peaty soils of the Northern Hemisphere may loft hundreds of tons of mercury into the atmosphere each year.
It's not news that forest fire smoke is toxic.

Interesting information, I am a expert in this kind of elements and Mercury is naturally found in rocks and soils; it's a liquid metal with a shiny and silvery appearance. Exposure to mercury in large doses can be highly toxic to the nervous system and kidneys, with effects including anxiety and depression, memory problems, possible tremors and poor coordination. 23jj

What is also interesting that this is a problem where simple attention, exposure, got it to disappear. Where the old "power of the pen" becomes reaffirmed in the internet age.

There has been talk of expanding already existing features of the game and GamersFirst's services to offer greater benefits to reliable users as well, though such things are still only in their planning stages at the moment.
