The effects of different cadmium concentrations [17 mg(Cd) kg−1(soil) and 72 mg(Cd) kg− 1(soil)] on Cannabis sativa L. growth and photosynthesis were examined. Hemp roots showed a high tolerance to Cd, i.e. more than 800 mg(Cd) kg−1(d.m.) in roots had no major effect on hemp growth, whereas in leaves and stems concentrations of 50 – 100 mg(Cd) kg−1(d.m.) had a strong effect on plant .

What is Metal plating? A Look at the Metal Plating Process .

The plating process is a manufacturing process in which a thin layer of metal coats a substrate. Metal plating provides many benefits to products made from metal and other materials. This can be achieved through electroplating, which requires an electric current, or through electroless plating, which is in autocatalytic chemical process.
