Noxious compounds

To deodorize a pet sprayed by a skunk, the noxious compound must be converted to an odorless one. Using an alkaline solution of 3% hydrogen peroxide and sodium bicarbonate, the thiol compound (denoted R-SH) can be oxidized to a disulfide compound,... 

Nonspecific antidiarrheal agents may be useful in treating self-limiting diarrhea. Kaolin and pectin or chalk may adsorb noxious compounds but evidence that such adsorbents are effective is unconvincing. Disadvantages can be prolongation of the course of infection and interference with absorption of desired drugs. 

Caution. The following synthesis involves noxious compounds (dimethylamine and metal carbonyls), and therefore the operations should be performed in a fume hood.

The treatment of gaseous emissions from potentially noxious compounds involves abatment of VOCs, SOx, NOx and greenhouse gases mainly. 

Biotic stress factors due to predation are usually severe in coral reefs whose biota is characterized by rich and diverse fauna and flora. Many of sessile organisms such as sponges, ascidians, soft corals, etc. have had toxins and noxious compounds to protect themselves fi om the predators. These compounds may be important sources for natural products based drugs and medicines [1-3]-... 

Avoid the use of polybrominated biphenyls and diphenyls or other noxious compounds as plastic additives. 

Furan and dioxin emissions are not a problem provided the flue gases are cooled rapidly to 260°C. Further research is being carried out to establish conditions to reduce the production of these noxious compounds.

A very marked stimulation of ascorbate synthesis in rats and mice can be evoked by exposure to various noxious compounds including the carcinogenic hydrocarbons, with methylcholanthrene the most powerful (40, 47, 80, 323). 

The Use of Biogas in MCFCs and SOFCs Technology Adsorption Processes and Adsorbent Materials for Removal of Noxious Compounds... 

In Chap. 1 different processes of biogas production (fermentation, digestion, etc.) are described evidencing the dependence of the gas composition and content of noxious compounds on the specific process and on the source of biomass. Attention is focused on the different types of compounds that can be harmful for high temperature fuel cells and their reformer systems such as sulfur compounds inorganic and organic) and siloxanes. 

Some years ago consumers were disturbed by a report that noxious compounds including D-amino acids are produced in microwaved food (56). However, several authors found afterwards that there are no differences in the content of D-amino acids between the microwave heating and conventional cooking methods (57, 38, 59). Also in the concentrations of the above mentioned markers (furosine ect.) no microwave-specific changes in food were found 40,41),... 

Adsorption onto the membrane does contribute to the removal of noxious compounds, such as interleukin-1 and interleukin-6 (lL-1, lL-6), tumor neaosis factor (TNF), peptides and 62-microglobuhn [71], As a result of the restricted surface area of dialyzers, however, adsorption capacity will rapidly be saturated. Acceptable rates of net removal by adsorption can only be achieved if the surface area is drastically increased by specifically designed devices [75, 76] or blood purification systems combining filtration and adsorption mechanisms in two devices, either arranged in parallel or in series. 

In conclusion it can be stated that CeOs, under different roles, is and probably will continue to be, the material of choice for catalytic application in the removal of noxious compounds. 

Many unusual and potentially noxious compounds have been isolated from another kind of opisthobranch molluscs, the sea hares or Aplysiidae. These animals can be easily collected in the intertidal zone and contain large quantities of metabolites which are identical with or closely related to metabolites of algae.
