The sites used in this study are often natural brown-water systems, with high contents of humic substances.
The maximum reduction of movable fractions (from F1 to F4) of Cu was observed in zeolite 2 and 3 treatments; it happened by maximum organic matter loss resulting in conversion of organic matter into humic substances which have high contents of carboxyl groups (Liu et al. 2008).
Even if bees consume nectars and/or pollens with high contents of deterrent secondary compounds (e.g., alkaloids, glycosides, phenolic substances), one has to keep in mind that combining deterrent substances such as quinine or LiCl with sucrose solution suppressed mortality in our experiments (see Fig. 2).
Poultry feeds have high content of proteinaceous substances that produce bigger chicken with more flesh content.
Red wines also have a high content of phenolic substances including catechin and resveratrol [ 177], which are responsible for the antioxidant action, anti-inflammatory, antiatherogenic property, oestrogenic growth-promoting effect, and immunomodulation.
According to Macheix et al., grapes are among the fruits containing the highest content of phenolic substances [ 3].
Pilsner Urquell has a high content of residual extract and hop substances; therefore, it is much more sensitive to poor handling than other beers.
Three kinds of sludge had a high content of protein in extracellular polymeric substances (EPS).
The high content of suspended solids can be correlated with all inorganic and organic substances contained in a liquid, the total dissolved substances in water and salinity in the mineral environment released from rabbit manures during mineralization in T4 and T2.
Jien et al. (2011) found coniferous vegetation with high content of alkyl-C, which was attributed to selective preservation of alkyl-C from lipids and aliphatic substances (Tegelaar et al. 1995).
The application of fatty substances to enhance the denitrification efficiency of high salinity wastewater with a high content of nitrates seems like a plausible strategy to resolve the above-mentioned issues.
