Toxicological Profiles. Toxicological Profiles (Tox Profiles) are a unique compilation of toxicological information on a given hazardous substance. Each peer-reviewed Tox Profile reflects a comprehensive and extensive evaluation, summary, and interpretation of available toxicological and epidemiological information on a substance.

glycosuria occurred in the zirconium, niobium and lead groups. Serum cholesterol was abnormal in the antimony and vanadium groups. Antimony and lead accumu­ lated in soft tissues, the former with age. No element was tumorigenic. Lead-fed males lost weight from 24 to 30 months of age and their coats were poor, the .-mly

It does help to have a concentration of tin in the mix before adding antimony. There is a way to use less tin and get the same results if you want. You could mix 2 pounds tin, 6 pounds antimony and only 14 pounds lead. This will make 9-27-64 tin/antimony/lead. Here you cast smaller ingots of the basically a foundry type alloy.

The hearts of males fed zirconium, niobium, antimony and vanadium weighed 14.6%, 12.2%, 18.9% and 18.3% less, respectively, than those of the controls, whereas the hearts of females weighed 3.5 to 7.4% more. Tumors. None of these 5 metals was tumorigenic (table 4), as evidenced by vis ible tumors at necropsy.

The two batteries were rated for the same number of amp-hours. This change, which cost virtually nothing, increased the runtime on the new UPS from less than 1 minute to 10 minutes. The trade off was a reduced operating life from 20 years to 12 years, but the increased runtime trumped the loss of operating life. 9.

In this regard, the development of lead-free halide perovskites by substituting Pb 2+ in the perovskite structure with less toxic metal centres such as the divalent lone-pair metal cations (Sn 2+, Ge 2+) and trivalent lone-pair cations (Bi 3+, Sb 3+) have been studied for integration into the wide optoelectronic field such as solar cell devices ...
