There are four different main components when it comes to the composition of a PCB: the substrate. the copper foil/sheeting. the solder mask. and the silkscreen. Let's start in the middle with the substrate and work our way outward. The beginning piece of a PCB is almost always the base substrate material.

Lead (Pb) and Zinc (Zn) are heavy metals commonly found at the same work places [1]. Both these metals have unique physical and chemical properties that make them suitable for great variety of applications. Pb has become common environmental and occupational contaminant widely distributed in the world.

The growth of A. paniculata was normal at 24–193 μM Pb, 153–1223 μM Zn and 9–89 μM Cd in the solution.However, necrosis and withered leaves were observed in the highest Pb, Zn treatments and Cd levels ≥178 μM, as well as in the control.When the solution Pb, Zn and Cd was increased to certain levels, the growth of A. paniculata was …
