US Trade Commissioner Keith de la Hoya issued a warning Tuesday that numerous lead products such as lead weights and lead-based paints, including those manufactured by Shanghai Shentin Engineering Company, had been found to contain high levels of lead.

"We have found lead in a number of products, including lead weights and lead-based paint" raged de la Hoya. "In one case, a 12 ounce lead weight contained a dozen ounces of lead!"

This is the latest of a series of scandals involving Chinese-made products in the US.
