True-that, cadmium is indeed gnarly stuff....
At the same time, NiCad batteries are in common usage far-&-wide in everything from tools to toys & quite possibly your laptop & smartphone. So, despite the alarm (& deservedly so), it looks to be a 'long' time before cadmium is no longer in widespread use......but the RoHS & Cd-free is a healthy step in the right direction anyway. https://www.batterystuff.com/kb/articles/battery-articles/what-the-heck-is-a-nicd-battery.html

Please reference a source on lead being "zero". Yes, companies may choose to use "zero" lead but the RoHS limit is still 1000ppm....

http://www.rohsguide.com/rohs-substances.htm
"Lead (Pb): < 1000 ppm
Lead is commonly used in the electrical and electronics industry in solder, lead-acid batteries, electronic components, cable sheathing and in the glass of cathode-ray tubes."


And as DD states, Cd is used in other applications so it will be many years before Cd is ever outright banned...if ever...

The zero tolerance for lead is for plumbing solder. that's why its good practice to remove your faucet aerators and run the water once a month, if you have an old home. bits of lead solder can break free only to be trapped at the tap.
