Hubert et al. [101] state that accelerated solvent extraction compared to alternatives such as Soxhlet extraction, steam distillation, microwave extraction, ultrasonic extraction and, in some cases, supercritical fluid extraction is an exceptionally effective extraction technique. Hubert et al. [ 101 ] studied the effect of operating variables such as choice of solvent and temperature on the solvent extraction of a range of accelerated persistent organic pollutants in soil, including chlorobenzenes, HCH isomers, DDX, polychlorobiphenyl cogeners and polycyclic aromatic hydrocarbons. Temperatures ofbetween 20 and 180 °C were studied. The optimum extraction conditions use two extraction steps at 80 and 140 °C with static cycles (extraction time 35 minutes) using toluene as a solvent and at a pressure of 15 MPa. [Pg.10]

Many persistent organic pollutants (POPs) are semivolatile compounds which undergo exchange between air and atmospheric particles, soils, and vegetation. Classes of POPs include polychlorinated biphenyls (PCBs), pesticides, polycyclic aromatic hydrocarbons (PAHs), and polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDDs, PCDFs). The distribution of these substances between the particle and gas phases in the atmosphere is a... [Pg.254]

Polycyclic aromatic hydrocarbons (PAHs) are a class of persistent organic pollutants (POPs) and widespread environmental contaminants, some of which may exhibit toxic, carcinogenic and mutagenic effects Because of their low water solubility and hydrophobic nature, PAHs are partitioned... [Pg.237]

Most, if not all, cmde food oils contain some contaminants. The most hazardous contaminants in edible oils and fats are the so-caUed persistent organic pollutants (POP). In 1995, the United Nations urged for immediate action on a group of 12 POP, including 8 chlorinated pesticides, polychlorinated biphenyl (PCB), hexachlorobenzene (HCB), polychlorinated dibenzo-p-dioxin (PCDD), and polychlorinated dibenzofuran (PCDF). Polycyclic aromatic hydrocarbons (PAH) are not on the shortlist, but their presence in edible oils is also a matter of concern. [Pg.2764]
