Abstract | An interim toxic emission inventory has been developed for the conterminous United States. Seven toxic metals found in lake and coastal waters are included: arsenic, cadmium, chromium, lead, mercury, nickel and selenium. The emissions are large relative to some estimates and demonstrate the importance of metal production in toxic metal emissions. In the absence of regional inventories dedicated to toxic emissions, there is a need for improvement of emission factors and speciation profiles for use with particulate emission inventories. |
