Phytoremediation of organic xenobiotics is generally based on mineralization or more frequently on degradation/transformation of the xenobiotics to environmentally less dangerous compounds, which are fixed in cell compartments or stored in the vacuole as soluble products or exuded back to the environment. Affection of the metabolic pathway by suppression or enhancement of expression of enzyme leading particular... [Pg.211]

This chapter gives an overview of microbiological biosensors on respiratory basis for the measurement of the following environmentally relevant compounds inorganic N-com-pounds, heavy metals, organic xenobiotics and the estimation of sum parameters or so-called complex parameters such as BOD, ADOC, N-BOD, and the inhibition of nitrification. [Pg.81]

The mechanism and extent of adsorption are ascertained to depend on several factors, which include (a) the physical and chemical nature and properties of both HS and organic xenobiotic and (b) the conditions of the medium. Organic matter in organic amendments is relatively fresh or little humified, has composition and properties that differ substantially from native soil HS, and affects the composition and structure of native soil HS. Therefore, organic xenobiotics added to soils interact with a complex mixture of applied and native HS, which is expected to affect both quantitative and mechanistic aspects of adsorption phenomena. [Pg.170]

A comprehensive review about the effect of DOM on the bioavailabilty of organic xenobiotics is given by Haitzer et al. (1998). Most studies show that DOM concentration of up to 10 mg liter-1 decreases the bioavailability of organic chemicals. It is also obvious that the difference in the character of the DOM due to its origin is of vital importance on the results. [Pg.388]

The covalent bonding of organic xenobiotic compounds to enzymes, as shown in Reaction 7.6.1, can cause enzyme inhibition. Such bonding occurs most commonly through hydroxyl (-OH) groups on enzyme active sites. Covalent bonding of xenobiotic compounds is one of the major ways in which acetylcholinesterase (an... [Pg.178]

In real life , humans and animals can be exposed to some toxicants both pre- and postnatally. Many organic xenobiotics have the potential to bioaccumulate within exposed individuals, possibly affecting future generations by way of genetic and epigenetic effects. However, reproductive endpoints, such as conception rates and sperm counts, are relatively insensitive, and subtle, toxicant-induced changes in reproductive efficiency can be overlooked or missed (Evans, 2007). [Pg.538]
