“…However, they pointed out that although they tried to relate plant levels of analysed compounds to temperature, temperature could actually be masking other effects in biological processes, snow cover and actual atmospheric concentrations. Hellström and coworkers (5) propose that pine needles can be used to map the distribution of lipophilic airborne pollutants and clearly show local hot spots. They suggest, however, that we may never be able to calculate absolute air concentrations because of difficulties caused by biological factors affecting the uptake.…”

Levels of six PCB congeners and seven organochlorine pesticides were investigated and compared in ambient air and in pine needle samples. The applied methods are suitable for the analysis of PCBs and organochlorine pesticides in environmental samples and for their detection in recent intakes. DDE, HCB, lindane, PCB-28, PCB-52, PCB-101, PCB-138 and PCB-153 were found in all pine needle and air samples. The highest median values were found for PCB-28, PCB-101 and γ-HCH, and the lowest for PCB-180 and DDD. The median value of α-HCH/ γ-HCH ratios was 0.2 in both matrices. DDE/DDT ratios were close to or below 1 in some pine needle and ambient air samples. The results showed a correspondence between air and pine needle pollution; the same compounds were present in the highest or in the lowest levels in both types of matrices. These results suggest that pine needles are passive biomonitors of air pollution.

“…In addition, they are widespread and can be found over large areas. One conifer tree branch has several year-classes of needles, which makes it possible to obtain a pollution profile for more than one year (5).…”

“…HCB, the only OCP analyzed, showed similar levels for Fóia and Benlhevai, and lower for Porto. Hellstrom [45] analyzed pine needles for organochlorine pesticides in Central and Northern Europe and found comparable incidences, between 0.16 and 10.10 ng g -1 (dw). Although no assessment between land uses was made, the author concluded that levels were quite uniform throughout Europe, which is in line with its enormous potential for LRAT.…”

Vegetation (and pine needles in particular) has been widely used as an alternative to other conventional sampling devices to assess the atmospheric presence of semi-volatile organic contaminants (SVOCs). While most analytical procedures developed focus only on one or two chemical classes, this this work intends to establish a multi-component protocol to quantify brominated flameretardants (BFRs), polychlorinated biphenyls (PCBs), organochlorine pesticides (OCPs), polynuclear aromatic hydrocarbons (PAHs) and one class of contaminant of emerging concern, the synthetic musks fragrances (SMCs). Pine needles extracts were obtained by ultrasonic solvents extraction (USE), and different cleanup approaches using solid-phase extraction (SPE) employing combinations of sorbents and solvents as well as gel permeation chromatography (GPC) were tested. SPE with alumina followed by GCP yielded the best results, with average recoveries over 80%. The application of the method under field conditions was proven by the analysis of naturally contaminated samples from 3 sites of different potential exposure (remote, rural and urban). The total detected concentrations ranged from 0.45 to 0.87 ng g -1 dry weight (dw) for BFRs, 0.35 to 1.01 ng g -1 (dw) for PCBs, 0.36 to 12.2 ng g -1 (dw) for HCB, 245.7 to 967.8 ng g -1 (dw) for PAHs and 20.7 to 277.5 ng g -1 (dw) for SMCs.This methodology is a viable approach for the simultaneous analysis of five different classes of atmospheric pollutants employing less analytical efforts. Moreover, to the author's best knowledge, this is also the first time vegetation 2 is employed in the detection of SMCs.

Niže temperature pospješuju sorpciju organoklorovih spojeva iz zraka, no uz to su važni i biološki procesi u samoj biljci, snježni pokrivač i stvarne koncentracije onečišćivača u atmosferi (44).…”

Institut za medicinska istraživanja i medicinu rada, Zagreb, HrvatskaU ovome preglednom radu prikazani su rezultati dobiveni diljem svijeta o raspodjeli i razinama 20 kongenera poliklorbifenila (PCB) i 7 organoklorovih pesticida (OCP) u uzorcima zraka, majčina mlijeka i borovih iglica. Istraživanja prisutnosti navedenih spojeva u tim uzorcima dugi niz godina provode se i u Institutu za medicinska istraživanja i medicinu rada te su u ovome preglednom radu sažeti i ti rezultati. Vidljivo je da su se koncentracije organoklorovih spojeva značajno snizile nakon zakonske zabrane njihove upotrebe, no to se snižavanje usporilo i oni se još nalaze u svim uzorcima. Općenito, više razine PCB-a nađene su u uzorcima s urbanog područja, razine pesticida više u onima gdje je vjerojatno u prošlosti postojala njihova primjena u poljoprivredi, dok je razina HCB-a obično pokazatelj industrijske aktivnosti. γ-HCH određen je u najvišoj koncentraciji u uzorcima zraka i borovih iglica, dok su u ljudima najzastupljeniji DDE i β-HCH. Indikatorski kongeneri PCB-a također su različito zastupljeni u okolišu i ljudima te su tako u zraku i borovim iglicama više koncentracije hlapljivijih nižekloriranih PCB-a, a u ljudima postojanijih višekloriranih PCB-a. Od toksičnih ortho-supstituiranih kongenera PCB-a i u uzorcima ljudi i okoliša najzastupljeniji je PCB-118, dok su najrjeđe detektirana tri najtoksičnija ne-ortho-supstituirana kongenera: PCB-77, PCB-126 i PCB-169. Od organoklorovih pesticida DDD u svim je uzorcima određen u najnižim koncentracijama. Arh Hig Rada Toksikol 2010;61:339-356 Poliklorbifenili (PCB) i organoklorovi pesticidi (OCP) dio su skupine spojeva poznate kao postojani organski onečišćivači (engl. Persistent Organic Pollutants; POPs). Pridjev postojani dobili su zbog svoje sposobnosti da se dugo zadrže u svim dijelovima okoliša, od tla i sedimenta, preko bilja i životinja, pa do čovjeka. KLJUČNE RIJEČI: crnogorično drveće, ljudi, onečišćenje okoliša, pesticidi, poliklorbifenili, razine organoklorovih spojeva Kožul D, Herceg Romanić S. PCBs AND OCPs IN AIR, PINE NEEDLES, AND HUMAN MILKPCB i OCP dugi su niz godina primjenjivani u raznim granama industrije, poljoprivredi i javnom zdravstvu. No, zbog svoga dugog zadržavanja u okolišu, kao i štetnih učinaka na zdravlje ljudi i životinja izloženih ovim spojevima, njihova je proizvodnja i upotreba u većini zemalja ograničena ili potpuno zabranjena. Ne postoje potpuno pouzdani podaci o tome koliko se tih spojeva proizvelo i upotrijebilo prije njihove službene zabrane te u kojoj su se mjeri nastavili ilegalno upotrebljavati i nakon toga. Također, postoje zalihe pesticida koji su zabranjeni ili čiji je rok uporabe istekao, a koje su velika opasnost za okoliš (1).Od organoklorovih pesticida istražuju se heksaklorbenzen (HCB), α, β i γ-izomeri heksaklorcikloheksana
