Well at least you didn't inhale.
Been their done that.
I use to spread it around the pine and spruce trees to save the lawn from the acid from the trees.
Where I use to live. The landlord had his yard hard filled with coal ash from a shoe factory. He had the most healthy pear,cherry,apple, and peach trees that I had ever seen. He also had blueberries, rasberries, grape vines, and rhubarb. It was about a one acre lot. But it had a huge amount of fruits to sell and give away. Its now a parking lot.
