What is PCB blood test?

What is PCB blood test?

There are tests that can measure if you have elevated levels of PCBs in blood, body fat or breast milk, from above normal exposure to PCBs in the past. A blood test is the best method for measuring exposure to large amounts of PCBs.

Can you repair a burnt circuit board?

Nevertheless, the damage can be repaired and the board restored to it original integrity – and even appearance – by the following procedure. Some specialized tools are needed, and the liquid epoxy repair material can even be colored, with color agents to replicate the color of the surrounding original board material.

What is PCB medical?

Medical PCBs are used in the cardiovascular field, for heart-related applications, like pacemakers. They are also used in medical imaging applications, like in MRIs. Third, they can be found in monitoring devices and gadgets such as body temperature monitors.
