The most popular .. incorporates .. vanadium. This new, more environmentally friendly coating is .. vanadate conversion coating. .. arsenate coatings may theoretically provide similar protection, at the risk of being a health hazard to humans and animals. Phosphates make algae go boom, so use fluoride, vanadium and arsenic?

Well, it certainly reads like one. Such pseudo-ecological BS puts wind in the sails of "eco-sceptics". As probably did RoHS, making our electronics way less reliable and prone to silent failure modes that are apparent only after the fact (or can be diagnosed only with X-rays like with BGA solder ball voids).

  This example is probably corporate propaganda. WRT RoHS, as someone who works with electronics, I'm glad RoHS is enforced at least as much as it is. We are exempt so far, so our old-school technicians use leaded solder for cobbled-together boards that I prefer to stay away from, especially their desks. AFAIK, all components/equipment we buy is RoHS compliant and we had 0 failures from lead-free solder issues. Lots of bad connectors, cables, heat on SSDs and batteries, short circuits, power applied at inappropriate places, botched soldering on leaded! boards in an assembly house, but I don't think we had solder issues with industrial RoHS boards. Even if we counted all unattributed component failures that could plausibly have something to do with solder (likely not), it would still be a small minority, maybe 10% of failures. Lead-free solder had issues while manufacturing adapted, but most issues have been mitigated, unless you're taking shortcuts for devices in harsh conditions. And if you really need it, there is high-reliability lead-free solder.
