“…Bennett et al (1998) calculated the characteristic travel distance of 2,3,7,8-TCDD to be in the range 100-1,000 km on assuming a mean wind speed of 4 m s −1 . Van Pul et al (1998) obtained residence times for TCDD and octachloro-dibenzofuran corresponding to travel distances of 1,900 and 370 km, respectively. Travel distance of 810 km for TCDD and 460 km for octachloro-dibenzodioxin has been calculated (Beyer et al 2000).…”

Toxic releases from medical waste incineration comprising organic emissions such as polychlorinated dibenzo-dioxin/furan (PCDD/Fs) and polycyclic aromatic hydrocarbons (PAHs), inorganic emissions and ashes containing toxic metals have been reviewed. Attempts made by various investigators to reduce/eliminate emissions have also been included. Legislations concerning emission standards for medical waste incinerators have been discussed.

“…In the atmosphere, some semi-volatile organic chemicals (SVOCs) are transported long distances before being deposited [1]. To evaluate whether the environmental release of a man-made chemical may need to be curtailed through international agreements like the Stockholm Convention on Persistent Organic Pollutants, a number of compound-specific hazard indicators is often determined and compared with threshold criteria [2].…”

Comparison of Atmospheric Travel Distances of Several PAHs Calculated by Two Fate and Transport Models (The Tool and ELPOS) with Experimental Values Derived from a Peat Bog Transect

Multimedia fate and transport models are used to evaluate the long range transport potential (LRTP) of organic pollutants, often by calculating their characteristic travel distance (CTD). We calculated the CTD of several polycyclic aromatic hydrocarbons (PAHs) and metals using two models: the OECD P OV & LRTP Screening Tool (The Tool), and ELPOS. The absolute CTDs of PAHs estimated with the two models agree reasonably well for predominantly particle-bound congeners, while discrepancies are observed for more volatile congeners. We test the performance of the models by comparing the relative ranking of CTDs with the one of experimentally determined travel distances (ETDs). ETDs were estimated from historical deposition rates of pollutants to peat bogs in Eastern Canada. CTDs and ETDs of PAHs indicate a low LRTP. To eliminate the high influence on specific model assumptions and to emphasize the difference between the travel distances of single PAHs, ETDs and CTDs were analyzed relative to the travel distances of particle-bound compounds. The ETDs determined for PAHs, Cu, and Zn ranged from 173 to 321 km with relative uncertainties between 26% and 46%. The ETDs of two metals were shorter than OPEN ACCESSAtmosphere 2014, 5 325 those of the PAHs. For particle-bound PAHs the relative ETDs and CTDs were similar, while they differed for Chrysene.

Green tea: protective action against oxidative damage induced by xenobiotics

The indiscriminate usage of synthetic chemicals and pesticides has led to a widespread contamination of land, water and air with harmful xenobiotics. The exposure to these toxicants results in severe health effects on organisms. Also, some natural foods contain harmless chemical species (nitrate), which however become toxic on certain conditions. Hence it is pertinent to focus attention on commonly consumed plant food materials, which can neutralize the toxicity damage caused by environmental agents. One of the most important sources of antioxidants is green tea. This review focuses on the mechanisms of oxidative damage caused by different xenobiotics and the defensive action of green tea in mitigating the damage. It is concluded that tea polyphenols, catechins and flavonoids scavenge reactive oxygen species and render a protective effect.
