“…Research also suggests that trees can be used as bio-indicators for pollution emission location and prediction (Reischl et al 1987(Reischl et al , 1989Gaggi et al 1985).

“…organic fatty compounds) actively accumulate in lipids on plant surfaces (the cuticle is composed of cutin, which is a lipid-based polymer) (Taiz and Zeiger 1991). The leaves of trees are highly lipophilic and due to lipophilic affinity, they are excellent accumulators of lipophilic foreign substances such as VOCs (Reischl et al 1987(Reischl et al , 1989. For example, as measured in field experiments, nitrogen based chemicals and compounds have shown high affinities for leaf cuticles and other plant surfaces (Asman et al 1998).…”

Recent reports clearly indicate that odor emitted from concentrated livestock production facilities in the Midwest of the US is a significant social problem that negatively impacts rural and state economies, human health, and the quality of rural life. A potential incremental approach to dealing with livestock odor is the use of shelterbelts arranged in strategic designs near and within livestock facilities. This review outlines the various ways that shelterbelts can be effective technology which bio-physically mitigates odor thereby reducing social conflict from odor nuisance. The biophysical potential of shelterbelts to mitigate livestock odor arises from the tree/ shrub impacts on the central characteristics and physical behavior of livestock odor. As the majority of odors generated in animal facilities that are detectable at appreciable distances travel as particulates, there is compelling evidence that shelterbelts can ameliorate livestock odor by impeding the movement of these particulates. Because the odor source is near the ground and the tendency of livestock odor is to travel along the ground, shelterbelts of modest heights (i.e. 20-30 ft) may be ideal for odor interception, disruption, and dilution. Shelterbelts can be adapted to fit almost any production situation. Depending on shelterbelt health, these trees can provide long term, year round odor interception, with increasing effectiveness over time. Additionally, more is becoming known about how landscape aesthetics affect how people might perceive livestock odor, suggesting that landscape elements such as shelterbelts can lead to aesthetic improvements and perhaps more positive opinions of livestock odor and the farm systems that create them.

“…For example, for these collected near to pulp/paper mill and waste combustion site OCDD and 123789HxCDF/1234678HpCDF dominated but OCDD and OCDF dominated near two pentachlorophenol wood-preserving sites, while at another site the profile typical of combustion with the total PCDFs content equal or greater than PCDDs and dominance of tetrato penta-CDFs and hexa-to octa-CDD was noted. [17,19,30] In a study in Korea, both OCDD and OCDF were a highly minor fraction of the total PCDD/Fs found in pine needles, while around the Tokyo Bay in Japan OCDD was important (up to around 50%), while OCDF was minor contributor. [14,18] The PCDD/Fs homologue group and congeners profiles of pine needles in this study are largely different from that reported recently for pine needles from neighbor to Poland the German sites, for which contribution from OCDD, and especially from OCDF is much lower, while comparable to that for forest soils in this country.…”

There is scarcity of data on sources, environmental diffusion and concentrations of PCDD/Fs and dioxin-like compounds in the Eastern and Central Europe. A study has been conducted using pine needles as passive matrix on diffusion of airborne 17 highly toxic PCDD/Fs in Poland. The target compounds were quantified using isotope dilution and HRGC/HRMS. One-year-old pine needles collected from 25 spatially distant sites in October 2002 revealed a relatively very low aerial emission and degree of pollution with PCDD/Fs. The most toxic 2,3,7,8-TCDD was absent (< 0.44 pg/g) in fresh pine needles sampled and absent at all sites were also 1,2,3,7,8-PeCDD, 1,2,3,4,7,8-HxCDD, 1,2,3,6,7,8-HxCDD, 1,2,3,7,8,9-HxCDD and 1,2,3,7,8,9-HxCDF (< 0.27 pg/g). OCDD at concentration range from 1.4 to 34 pg/g and OCDF at range from 1.5 to 41 pg/g were the only among 17 compounds found at each site, and next in prevalence was 1,2,3,4,7,8,9-HpCDF (total range from < 0.41 to 8.1 pg/g), which was found at 24 off 25 sites. The I-TEQ transformed concentrations of PCDD/Fs of pine needles of Poland ranged from < 0.01 to 1.28 pg/g ww or from 0.01 to 3.18 pg/g dw. The CDD/F homologue groups and congeners profiles of pine needles with highly dominant HpCDD/F and OCDD/F found in this survey suggest on lack of significant other than coal/lignite/wood combustiont sources of PCDD/Fs diffusion to ambient air in Poland.

“…It has been shown that penetration into the leaf occurs for more volatile compounds that are taken up by leaves via dry gaseous deposition (Ko$ niger et al, 1991 ;Riederer, 1995 ;Sinkkonen et al, 1995). The evidence indicates that the degree of penetration into the leaf increases with diminishing partition coefficient or increasing vapour pressure of the chemical (Reischl et al, 1987 ;Schreiber et al, 1996).…”

The fate of polychlorinated dibenzo-p-dioxins and dibenzofurans and polycyclic aromatic hydrocarbons deposited to maize leaves under ambient conditions was investigated, with focus on those compounds that are primarily associated with particles in the atmosphere. Leaf samples collected from mature maize plants over an 8-wk period were subjected to four extraction procedures : (1) rinsing with distilled water ; (2) shaking in aqueous EDTA solution ; (3) immersion in chloroform\methanol ; (4) soxhlet extraction with toluene. Of the compounds deposited primarily in association with particles, 20% of the total leaf contamination was present in the first two aqueous extracts, indicating that only a small portion of these substances was subject to ready erosion from the leaf surfaces. Some 50-60% of the chemical was present in the third extract, while 20-40% was found in the final extract. The chemical in the final extract was no longer associated with particles, since these had been removed with the first three extractions. This chemical must have desorbed from the particles with which it was originally deposited, and migrated through the epicuticular waxes. Model calculations indicated that 15-35% of the chemical in the third extract had also desorbed from the particles, and there was evidence that polychlorinated dibenzo-p-dioxins and dibenzofurans desorb more readily than polycyclic aromatic hydrocarbons. It is concluded that desorption of chemical from particles and subsequent transport through the cuticle is an important process determining plant accumulation of organic contaminants associated with atmospheric particles.Key words : polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD\F), polycyclic aromatic hydrocarbons (PAH), leaf, atmospheric particles, deposition, retention. A large part of human exposure to lipophilic organic compounds such as polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD\Fs) and polycyclic aromatic hydrocarbons (PAHs) occurs via the agricultural food chain. Under most conditions atmospheric deposition is the main pathway of these compounds to agricultural plants, and thereby into the agricultural food chain (McLachlan, 1996). The atmospheric input of the compounds into the plants can proceed through different mechanisms : dry gaseous deposition, dry particle-bound deposition, and wet deposition. The recent literature reveals that each of these three deposition pathways can contribute to the total plant burden, the relative
