چکیده
I am writing this letter on behalf of the International Diatomite Producers Association (“IDPA”), a trade association of producers of diatomaceous earth products that was formed in 1987. IDPA includes in its membership companies both doing business and operating facilities in the state of California. IDPA sponsored one of the principal epidemiology studies relating to crystalline silica exposure and the potential risk of lung disease, and has been a leader in developing safe work practices for the use and handling of diatomaceous earth, which contains crystalline silica.

متن کاملEnergetics of Zn2+ adsorption in silicate MEL-type nanoporous material
Density-functional-based and ab initio calculations were implemented at different computational levels to estimate the binding energy of Zn2+ ion adsorbed on the available sites of a silicate MEL-type adsorbent. B3LYP and MP2 were used in combination with the 6-31G*, 6-31+G*, LanL2DZ, 6-311+G*, and Def2-TZVP basis sets. The zinc cation was found to preferentially occupy the 6MR sites followed b...
