Tissues of living

When microscopists began to look at the tissues of living forms they already had in their minds a view of matter as an aggregate of more or less uniform microscopic components. It is therefore understandable that when they saw everywhere agglomerations of more or less spherical halations, they concluded that these optical illusions were the fundamental subunits of animate matter, and when they actually saw cells they had no idea what they were (Harris, 1999, p. 39-...

Persistent organic pollutants (POPs) are organochlorine compounds widely used as pesticides and/or industrial chemicals. These chemicals share four common properties highly toxic, persistent, capable of long-range transport and bio-accumulation in the fatty tissues of living... 

The hydrophobicity of an organic molecule is quantified by means of its partition coefficient between octanol and water (Kow)- Kow is equal to the ratio of compound concentrations at saturation in n-octanol and in water at equilibrium and at a specific temperature. n-Octanol possesses structural properties analogous to lipidic tissues of organisms, and so Kow allows evaluation of the lipophilic character of the contaminant and thus of its capacity to be accumulated in the lipidic tissues of living organisms. The Kow value of hydrophobic organic pollutants (HOPs) is higher than 100. They are nonpolar molecules with a low water solubility. Their weak solubility and their hydrophobicity...

Ascorbic acid occurs in all the tissues of living organisms where it is responsible for the normal functioning of important metabolic processes. Vegetable foodstuffs (oranges, blackcurrants, parsley, green peppers, etc.) are the richest sources of vitamin C, but animal products contain relatively little ascorbic acid, l-Ascorbic acid is a six carbon weak acid with a pA", of 4.2, which is reversibly oxidized due to its enediol structure with the loss of an electron to form the free radical semihy-droascorbic acid. ... 

Except for crab exoskeletons, gold recovery from the medium by various species of living molluscs, crustaceans, and fishes is negligible. The maximum concentration of stable gold measured in tissues of living marine organisms was 38.0 xg/kg FW. 

Persistent Organic Pollutants (POPs) and Persistent, Bioaccumulative and Toxic (PBT) substances are carbon-based chemicals that resist degradation in the environment and accumulate in the tissues of living organisms, where they can produce undesirable effects on human health or the environment at certain exposure levels (Pavan Worth, 2006).
