| Along with the "man-made chemical" scam. (Hint: Except for some transuranic elements created briefly in laboratories, there are no "man made chemicals".) |
Perhaps you're confusing man-made chemicals with man-made elements?
Elements are the building blocks for chemicals, they are not interchangable.
For instance two atoms of the element Hydrogen (H) and one atom of the element Oxygen (O) make up the chemical Dihydrogen Monoxide (H2O) commonly referred to as water.
H2O is a chemical, Oxogen and Hydrogen are elements. It is correct that there are no man-made elements other than some transuracic ones which are created mostly in nuclear reactions.
The term man-made chemicals refers to chemical compounds, which are many elements chained together. There are many of these, they are not unusual, they're all around us. Your fingers are probably touching the plastic of your mouse right now. Many of these combinations of elements absolutely do not exist in the natural world and are entirely "man-made". Some are beneficial, particularly phamaceuticals. Some are unbelievably toxic, particularly dioxins. Some are neutral, like most plastics. All are most definitely man-made.
