Do the Wales 40 Palette Eyeshadows contain Lead?

Wales,Coastal Scents,Manly and BF are all buying from the same manufacturer in CHINA and I have read that they do contain higher levels of lead than is approved. The lead won't make you sick right away or go blind it just stores in your body because your body can not eliminate lead it just stays in your body and one day you wake up and BOOM CANCER! then what was it truly worth it to look cute with great colors for a few years and then spend the rest of your life vomitting from the Chemo and going bald. I rather keep my hair and be healthy with less colors in my makeup.
