ANSWER:The use of lead has been reduced over the years because exposure to lead can cause health and reproductive problems. The reason is lead is a heavy metal and once introduced into your body, it is almost impossible to remove it again. Lead has been removed from most paints produced in the US, although some foreign countries do not feel this is in their best interests to use lead free paints and products to the detriment of their citizens. The US has also removed lead from the gasoline we use. See the related link for more information on lead poisioning.

Tin-lead solders were most often used because they are easily melted and inexpensive. Lead-based solders have a few problems which are reducing their popularity: - Environmental concerns about e-waste - Worker safety concerns for people who constantly work with solder - The low melting point, which is not suitable for modern microprocessors Any metal which is melted to bond to another metal is a solder.

But there are industries in which the lead-free solders are not acceptable.
