Monitoring, pollution

Mld-IR sensor systems can be used onsite for the determination of organic pollutants in soils, aquifers, and marine environments. For Instance, Sanghera et al. deployed (Fig. 7.15] a 20 m long fiber combined with a portable FTIR unit and a cone penetrometer to detect diesel fuel contamination in soils and marine sands [167]. 

Furthermore, preliminary pilot-scale tests were led in an artificial aquifer with a 2 m long flexible As2oSe3oTe5o fiber [168]. The study showed that FEWS enables detection of weak concentrations of pollutants, down to 1 ppm for chlorinated hydrocarbons, specifically C2CI4, in the aquifer inlet as a function of time. These studies illustrate

Under the conditions of increasing antropogenic environmental pollution monitoring of toxic metals (Pb, Cd, Zn, Al, Mo, Cr, Bi) is a very actually. The big number and difficult of analyzes which necessary for solving this problem need new express and effective methods.

DNA analysis, performance of polymerase chain reactions, clinical assays for pH, enzymes, proteins, oxygen etc., trace pollution monitoring and other sorts of biological analyzes are at the focus of recent developments [5]. Another reference lists environmental monitoring (including speciation), clinical monitoring, and quality control in production processes as applications of pTAS equipment in chemical analysis [30].

Lichens accumulate trace elements from the atmosphere and thus are frequently used instead of air filters for pollution monitoring. Certification of nine elements (Al, As, Cd, Cr, Cu, Hg, Mo, Ni, Pb, and Zn) by a group of ii selected laboratories was performed in BCR CRM 482 (Lichen) after an inter-comparison on trace elements in samples of this material (Quevauviller et al. 1996b). 

SPE has been applied to phthalate esters (plasticisers in PVC), polar pesticides (agricultural usage) and for other continuous pollution monitoring problems and environmental analyses [272]. For these applications SPE has largely displaced LLE as the preferred technique for the preparation of liquid samples, e.g. EPA method 506 is concerned with the determination of phthalates and adipate esters in drinking water.
