Sadly for most prospective owners, they will need a comprehensive tool kit and a fair working knowledge of high voltage systems in order to access the said cadmium in the charger in order to be able manage to poison themselves or families.
It is irresponsible to downplay cadmium poisoning without knowing more facts about Volkwagen's use of cadmium: cadmium is a heavy metal that is effectively retained in the human body, once cadmium gets absorbed by the human body it will stay there for decades. The biological half-life of cadmium is 10-35 years.
Cadmium primarily accumulates in the liver and in the kidney. In young children it causes brain damage, in women breast cancer, in men prostate cancer, in everyone it can cause lung cancer. Hundreds of cadmium related deaths were documented in cadmium processing industries before it was banned in Europe.
Just to give a notion of how little cadmium exposure is sufficient to cause health problems:
- Japan, where cadmium contamination of rice caused widespread health problems, the cadmium content of rice is around 50 nano-gram per gram, i.e. with 100g of daily rice intake a daily dose of 5 micro-grams of cadmium
- The daily exposure in these cadmium processing industries was typically 30 micro-gram of cadmium (through breathed in air)
While the cadmium in Volkswagen electric vehicles is ostensibly enclosed safely in plastic, it could get out of there due to damage, corrosion, accidents or vehicle fire. Also, we don't know the chemical composition of the Cadmium in Volkswagen vehicles: its toxicity highly depends on what chemical form it is in, and how concentrated the cadmium is. (It's more dangerous than lead-acid batteries, because most lead compounds are less reactive than cadmium.)
I.e. we need more data - and saying that it's "just" 0.008 grams is irresponsible.
