RoHS restricts use of which substance?
The Restriction of the use of certain Hazardous Substances (RoHS) Directive restricts the producers of eight categories of electrical and electronic equipment from placing on the market products that contain six "banned" substances unless specific exemptions apply. These six substances are: Lead, Mercury, Hexavalent chromium, Cadmium, Polybrominated biphenyl flame retardants and Polybrominated diphenyl ether flame retardants. The phrase 'banned' is misleading as you can have minute concentrations values but they are so small that it effectively prevents their use. The maximum concentration values (MCV) are 0.1 % by weight of lead, mercury, hexavalent chromium, PBB and PBDE and 0.01 % by weight cadmium in homogeneous materials.

What coffee contains cadmium?
I have heard that coffee plants naturally up-concentrate cadmium to act as an insecticide, or as a defense strategy to make themselves inhospitable to insects. Is this true? There are many reports that coffee is a common source of cadmium. That coffee plants are 'tolerant' to cadmium. Is this because, like fish methylating mercury to protect themselves from its (mercury's) toxicity, coffee is deliberately utilizing cadmium's toxic nature to protect itself?
