I read with interest about a Chinese engineer who is coping with cadmium poisoning. Cadmium is a heavy metal that is used in batteries. China is a number one producer of cadmium batteries, which are then shipped to markets around the world. Walmart, Mattel, and other major US companies use Cadmium batteries because they hold a charge longer than other types of batteries, and can deliver a good "punch" for motors.
But the manufacture of cadmium batteries can create a dust of cadmium, which is then inhaled by workers.
More can be read about that engineer's story by accessing the Wall Street Journal online, or picking up the Jan 15th issue from your local library.
It's an interesting read, because it also illustrates the balance that industry must take to make a profit but still safeguard the health and safety of the workers.
