Toxic compounds, storage

Another important storage depot for toxic compounds is the skeleton. In particular, cadmium and lead bind and accumulate in the bone tissue from which they are released very slowly. The half-life of elimination of cadmium is several years, the half-life of lead is several months. 

Repeating for emphasis - not aU poorly water-soluble compounds are equally solubilized by DMSO. The greaseball compounds will be much better solubilized than the brickdust compounds. The most common range of compound in DMSO stock concentrations in compound storage repositories is 2-20 mM. At conferences, organizations employing 2mM compound in DMSO stock solutions report fewer solubility problems. The downside is that the lower stock concentrations are more Hmited in utility in some absorption, distribution, metabolism, excretion and toxicity assays that require higher compound concentration. 

Storage of fats and oils leads to rancidity, a largely oxidative deterioration that causes development of unpleasant tastes, odors, and toxic compounds.239 Similar chemical changes account for the "drying" of oil-based paints and varnishes. These reactions occur... 

Various types of serum are fetal bovine serum—the most widely used type, newborn calf serum— which is derived from animals less than 10 days of age, donor calf serum—which is obtained from processed whole blood of calves up to 8 mo old, and horse serum. Human serum and chicken serum have specialized uses for those cells that require a serum derived from similar species, e.g., chicken serum has been repeatedly used for growing various types of avian cells. Serum can be stored safely for over 12 mo at —20°C and longer storage is possible at —70°C. Serum can also be heat inactivated (incubation at 56°C for 30 min) to remove toxic compounds or other agents that can interfere with tissue typing assays.

In connection with the realisation of the Program Of Phased CW Destruction In Russia, first it is necessary to qualify the environmental conditions in regions of chemical weapons storage, destruction and former production or, in other words, to carry out comprehensive studies of areas which have been related or are now relevant to chemical weapons, their pollution by chemical warfare agents (WA), their transformation products (TP) and another toxic compounds. 

One of the main apphcations of polymer cryogels is their use in biotechnology as carriers of cells, bacteria, and enzymes [1, 2]. The advantages of immobilized microorganisms over cultures in suspension include the easier collection and purification of bioproducts, better stability and performance under storage and operational conditions, tolerance against toxic compounds, etc.
