The operating costs of vapour destruction systems can be reduced in an autothermal after-burning mode if the concentration of the carbon compounds in the waste is high enough. 
Obratovalne stroške sistemov za uničevanje hlapov je mogoče znižati z naknadnim zgorevanjem brez dovajanja toplote, če je koncentracija ogljikovih spojin v odpadkih dovolj visoka.

B. Anode production 
B. Proizvodnja anod
PAH emissions from anode production have to be dealt with in a similar fashion as those from coke production. 
Emisije PAH iz proizvodnje anod je treba obravnavati podobno kot emisije iz proizvodnje koksa.
The following secondary measures for emission reduction of PAH-contaminated dust are used: 
Za zmanjšanje emisij prahu, onesnaženega s PAH, se uporabljajo naslednji sekundarni ukrepi:
(a) Electrostatic tar precipitation; 
(a) elektrostatično izločanje katrana;
(b) Combination of a conventional electrostatic tar filter with a wet electrostatic filter as a more efficient technical measure; 
(b) kombinacija klasičnega elektrofiltra za katran in mokrega elektrofiltra kot učinkovitejšega tehničnega ukrepa;
(c) Thermal after-burning of the waste gases; and 
(c) toplotno naknadno zgorevanje odpadnih plinov in
(d) Dry scrubbing with limestone/petroleum coke or aluminum oxide (Al(2)O(3)). 
(d) suho čiščenje prahu z apnencem/petrolkoksom ali aluminijevim oksidom (Al(2)O(3)).
The operating costs in thermal after-burning can be reduced in an autothermal after-burning mode if the concentration of carbon compounds in the waste gas is high enough. 
Obratovalne stroške za postopek toplotnega naknadnega zgorevanja je mogoče zmanjšati s pomočjo naknadnega zgorevanja brez dovajanja toplote, če je koncentracija ogljikovih spojin v odpadnem plinu dovolj visoka.

V preglednici 5 je povzetek ukrepov za zmanjšanje emisij PAH pri proizvodnji anod.
PAH emission control for anode production 
Nadzorovanje emisij PAH pri proizvodnji anod
Aluminium is produced from aluminium oxide (Al(2)O(3)) by electrolysis in pots (cells) electrically connected in series. 
Aluminij se proizvaja iz aluminijevega oksida (Al(2)O(3)) z elektrolizo v zaporedno vezanih posodah (celicah).
Pots are classified as prebake or Soederberg pots, according to the type of the anode. 
Glede na vrsto anode gre bodisi za posode s predpečenimi anodami bodisi za Soederbergove posode.
Prebake pots have anodes consisting of calcined (baked) carbon blocks, which are replaced after partial consumption. 
Posode s predpečenimi anodami so opremljene z anodami kalciniranih (žganih) blokov ogljika, ki se po delni porabi zamenjajo.
Soederberg anodes are baked in the cell, with a mixture of petroleum coke and coal tar pitch acting as a binder. 
Soederbergove anode so žgane v celici z mešanico petrolkoksa in katranske smole, ki deluje kot vezivo.
Very high PAH emissions are released from the Soederberg process. 
Pri Soederbergovem postopku se sproščajo zelo velike emisije PAH.
Primary abatement measures include modernization of existing plants and optimization of the processes, which could reduce PAH emissions by 70-90%. 
Med primarne ukrepe zmanjševanja emisij sodita posodabljanje obstoječih obratov in optimiziranje tehnoloških postopkov, s katerimi bi bilo mogoče zmanjšati emisije PAH za 70 do 90%.
An emission level of 0.015 kg B(a)P/tonne of Al could be reached. 
Doseči je mogoče stopnjo emisije 0,015 kg B(a)P/tono aluminija.
Replacing the existing Soederberg cells by prebaked ones would require major reconstruction of the existing process, but would nearly eliminate the PAH emissions. 
Zamenjava obstoječih Soederbergovih celic s predpečenimi anodami bi sicer zahtevala obsežno rekonstrukcijo obstoječega postopka, vendar bi skoraj v celoti odpravila emisije PAH.
The capital costs of such replacements are very high. 
Investicijski stroški za tako zamenjavo so zelo visoki.

PAH emissions from residential combustion can be detected from stoves or open fireplaces especially when wood or coal is used. 
Emisije PAH iz kurišč v gospodinjstvih je mogoče zaslediti, kadar se v pečeh oziroma štedilnikih ali v odprtih ognjiščih kuri les ali premog.
Households could be a significant source of PAH emissions. 
Gospodinjstva so lahko pomemben vir emisij PAH.
This is the result of the use of fireplaces and small firing installations burning solid fuels in households. 
To je posledica uporabe trdnih goriv v ognjišč in malih kurilnih napravah v gospodinjstvih.
In some countries the usual fuel for stoves is coal. 
V nekaterih državah je običajno gorivo za peči in štedilnike premog.
Coal-burning stoves emit less PAH than wood-burning ones, because of their higher combustion temperatures and more consistent fuel quality. 
Zaradi višje temperature zgorevanja in enakomernejše kakovosti goriva so emisije PAH iz peči na premog manjše kot iz peči na drva.
Furthermore, combustion systems with optimized operation characteristics (e.g. burning rate) effectively control PAH emissions from residential combustion. 
Poleg tega je mogoče učinkovito zmanjšati emisije PAH iz gospodinjstev z izboljšanjem lastnosti zgorevalnih sistemov (na primer hitrost zgorevanja).
Optimized combustion conditions include optimized combustion chamber design and optimized supply of air. 
Med izboljšane lastnosti zgorevalnih sistemov sodita boljša zasnova zgorevalne komore in izboljšan dovod zraka.
There are several techniques which optimize combustion conditions and reduce emissions. 
Na voljo je več tehnik za izboljšanje lastnosti zgorevalnih sistemov in zmanjšanje emisij.
There is a significant difference in emissions between different techniques. 
Glede na različne tehnike se stopnja emisij bistveno razlikuje.
A modern wood-fired boiler with a water accumulation tank, representing BAT, reduces the emission by more than 90% compared to an outdated boiler without a water accumulation tank. 
Z uporabo sodobnih kotlov na les z zbirno posodo za vodo, ki so ena od tehnik BAT, se zmanjšajo emisije za več kot 90% v primerjavi z zastarelimi kotli brez zbirne posode za vodo.
A modern boiler has three different zones: 
Sodobni kotel ima tri prekate:
a fireplace for the gasification of wood, a gas combustion zone with ceramics or other material which allow temperatures of some 1000°C, and a convection zone. 
kurišče za uplinjanje lesa, prekat za zgorevanje plina s keramiko ali kakšnim drugim materialom, ki omogoča temperaturo okrog 1000 °C, in konvekcijski prekat.
The convection part where the water absorbs the heat should be sufficiently long and effective so that the gas temperature can be reduced from 1000°C to 250°C or less. 
Konvekcijski del, kjer voda absorbira toploto, mora biti dovolj dolg in učinkovit, da se temperatura plinov lahko zmanjša s 1000 °C na 250 °C ali manj.
There are also several techniques to supplement old and outdated boilers, for example with water accumulation tanks, ceramic inserts and pellet burners. 
Obstaja tudi več načinov, kako nadomestiti stare in zastarele kotle, na primer z zbirnimi posodami za vodo, keramičnimi vložki in briketnimi gorilniki.
Optimized burning rates are accompanied by low emissions of carbon monoxide (CO), total hydrocarbons (THC) and PAHs. 
Z izboljšanjem hitrosti zgorevanja se zmanjšajo emisije ogljikovega monoksida (CO), skupnih ogljikovodikov (- THC) in PAH.
Setting limits (type approval regulations) on the emission of CO and THCs also affects the emission of PAHs. 
Posledica omejitev emisij CO in THC (predpisi o tipskih atestih) so tudi majhne emisije PAH.
Low emission of CO and THCs results in low emission of PAHs. Since measuring PAH is far more expensive than measuring CO, it is more cost-effective to set a limit value for CO and THCs. 
Merjenje PAH je precej dražje kot merjenje CO, zato je gospodarneje določiti mejne vrednosti za CO in THC.
Work is continuing on a proposal for a CEN standard for coal and wood-fired boilers up to 300 kW (see table 7). 
Nadaljuje se delo v zvezi s predlogom za standard CEN za kotle na les in premog do 300 kW (glej preglednico 7).

Stopnje emisij v mg/m3 pri 10% O(2).70. Emisije iz peči in štedilnikov na les v gospodinjstvih je mogoče zmanjšati:
(a) For existing stoves, by public information and awareness programmes regarding proper stove operation, the use of untreated wood only, fuel preparation procedures and the correct seasoning of wood for moisture content; and 
(a) za obstoječe peči in štedilnike z obveščanjem javnosti in s programi ozaveščanja o pravilni uporabi peči in štedilnikov, uporabi izključno neobdelanega lesa, postopkih priprave in pravilnega sušenja lesa, da bi se zmanjšala njegova vlažnost, in
(b) For new stoves, by the application of product standards as described in the draft CEN standard (and equivalent product standards in the United States and Canada). 
(b) za nove peči in štedilnike z uporabo standardov za izdelke, navedenih v osnutku standarda CEN (in ustreznih standardov za izdelke v ZDA in Kanadi).
More general measures for PAH emission reduction are those related to the development of centralized systems for households and energy conservation such as improved thermal insulation to reduce energy consumption. 
Obstajajo splošnejši ukrepi za zmanjšanje emisij PAH, in sicer razvoj centraliziranih sistemov za gospodinjstva in ukrepi varčevanja z energijo, na primer boljša toplotna izolacija.
Information is summarized in table 8. 
Možni ukrepi so navedeni v preglednici 8.

E. Wood preservation installations 
.E. Obrati za zaščito lesa
Wood preservation with PAH-containing coal-tar products may be a major source of PAH emissions to the air. 
Zaščita lesa z derivati premogovega katrana, ki vsebujejo PAH, je lahko pomemben vir emisij PAH v zrak.
Emissions may occur during the impregnation process itself as well as during storage, handling and use of the impregnated wood in the open air. 
Do emisij lahko pride med samim postopkom impregniranja, pa tudi med skladiščenjem, prestavljanjem in uporabo impregniranega lesa na prostem.
The most widely used PAH-containing coal-tar products are carbolineum and creosote. 
Katranska derivata z najširšo uporabo, ki vsebujeta PAH, sta karbolinej in kreozot.
Both are coal tar distillates containing PAHs for the protection of timber (wood) against biological attack. 
Oba sta destilata premogovega katrana, vsebujeta PAH in sta namenjena zaščiti žaganega lesa pred biološkimi škodljivci.
PAH emissions from wood preservation, installations and storage facilities may be reduced using several approaches, implemented either separately or in combination, such as: 
Emisije PAH iz obratov za zaščito lesa in prostorov za skladiščenje je mogoče zmanjšati z uporabo različnih pristopov, uporabljenih bodisi posamezno bodisi skupaj, kot so:
(a) Requirements on storage conditions to prevent pollution of soil and surface water by leached PAH and contaminated rainwater (e.g. storage sites impermeable to rainwater, roof cover, reuse of contaminated water for the impregnation process, quality demands for the material produced); 
(a) zahteve glede skladiščenja, da bi se preprečilo onesnaževanje prsti in površinske vode z izluženimi PAH in onesnaženo meteorno vodo (na primer skladiščni prostori, zavarovani pred dežjem, nadstreški, ponovna uporaba onesnažene vode v postopku impregniranja, zahteve glede kakovosti izdelkov);
(b) Measures to reduce atmospheric emissions at impregnation plants (e.g. the hot wood should be cooled down from 90°C to 30°C at least before transport to storage sites. 
(b) ukrepi za zmanjšanje emisij v ozračje iz obratov za impregniranje (na primer preden se les odpelje v skladišče, ga je treba ohladiti z 90 °C vsaj na 30 °C.
However, an alternative method using pressure steam under vacuum conditions to impregnate the wood with creosote should be highlighted as BAT); 
Kot tehniko BAT je treba omeniti nadomestno možnost uporabe tlaka vodne pare v podtlačnih razmerah za impregniranje lesa s kreozotom);
(c) The optimum loading of wood preservative, which gives adequate protection to the treated wood product in situ, can be regarded as a BAT as this will reduce the demand for replacements, thereby reducing emissions from the wood preservation installations; 
(c) za tehniko BAT je mogoče imeti čim ustreznejši nanos zaščitnega sredstva, s katerim se les ustrezno zaščiti in situ, s čimer se zmanjša potreba po zamenjavi, s tem pa tudi zmanjšujejo emisije iz obratov za zaščito lesa;
(d) Using wood preservation products with a lower content of those PAHs that are POPs: 
(d) uporaba izdelkov za zaščito lesa z manjšo vsebnostjo tistih PAH, ki so obstojna organska onesnaževala:
Possibly using modified creosote which is taken to be a distillation fraction boiling between 270°C and 355°C, which reduces both the emissions of the more volatile PAHs and the heavier, more toxic PAHs; 
po možnosti se uporablja modificirani kreozot, ki naj bi bil frakcija z vreliščem med 270 °C in 355 °C, s čimer se zmanjšajo emisije bolj hlapnih PAH in težjih, bolj strupenih PAH;
Discouraging the use of carbolineum would also reduce PAH emissions; 
odsvetovanje uporabe karbolineja bi prav tako omogočilo zmanjševanje emisij PAH;
(e) Evaluating and then using, as appropriate, alternatives, such as those in table 9, that minimize reliance on PAH-based products. 
(e) presoja in ustrezna uporaba nadomestnih možnosti, na primer tistih, navedenih v preglednici 9, s katerimi se na najmanjšo mero zmanjša uporaba izdelkov, ki vsebujejo PAH.
Burning of impregnated wood gives rise to PAH emissions and other harmful substances. 
Pri gorenju impregniranega lesa nastajajo emisije PAH in drugih škodljivih snovi.
If burning does take place, it should be done in installations with adequate abatement techniques. 
Če se tak les že sežiga, bi moralo gorenje potekati v napravi, ustrezno opremljeni za zmanjševanje emisij.

In some countries, 1,2-dibromomethane in combination with 1,2-dichloromethane is used as a scavenger in leaded petrol. 
V nekaterih državah se uporablja 1,2-dibromometan v kombinaciji z 1,2-diklorometanom kot dodatek v osvinčenem bencinu.
Moreover, PCDD/F are formed during the combustion process in the engine. The application of three-way catalytic converters for cars will require the use of unleaded fuel. 
Poleg tega med zgorevanjem v motorju nastajajo PCDD/F. Za uporabo tristeznih avtomobilskih katalizatorjev bo potrebno neosvinčeno gorivo.
The addition of scavengers and other halogenated compounds to petrol and other fuels and to lubricants should be avoided as far as possible. 
Če je to mogoče, se je treba izogibati dodajanju dodatkov in drugih halogeniranih spojin bencinu in drugim gorivom ter mazivom.

CONTROL MEASURES FOR EMISSIONS OF POPs FROM MOBILE SOURCES 
UKREPI ZA ZMANJŠANJE EMISIJ OBSTOJNIH ORGANSKIH ONESNAŽEVAL (POP) IZ PREMIČNIH VIROV
A. POP emissions from motor vehicles 
A. Emisije POP iz motornih vozil
POP emissions from motor vehicles occur as particle-bound PAHs emitted from diesel-fuelled vehicles. 
Emisije POP iz motornih vozil se pojavljajo kot na delce vezani PAH, ki jih oddajajo vozila z dizelskim motorjem.
To a minor extent PAHs are also emitted by petrol-fuelled vehicles. 
PAH v manjšem obsegu oddajajo tudi vozila z bencinskim motorjem.
Lubrication oil and fuels may contain halogenated compounds as a result of additives or the production process. 
Zaradi dodatkov ali proizvodnega postopka lahko mazivno olje in goriva vsebujejo halogenirane spojine.
These compounds may be transformed during combustion into PCDD/F and subsequently emitted with the exhaust gases. 
Te spojine se lahko med zgorevanjem pretvorijo v PCDD/F in se pozneje izločijo z izpušnimi plini.
B. Inspection and maintenance 
B. Pregled in vzdrževanje
For diesel-fuelled mobile sources, the effectiveness of the control of emissions of PAHs may be ensured through programmes to test the mobile sources periodically for particulate emissions, opacity during free acceleration, or equivalent methods. 
Pri premičnih virih z dizelskim motorjem se lahko učinkovitost nadzora nad emisijami PAH zagotovi s programi za občasen nadzor nad emisijami trdnih delcev, merjenjem motnosti pri pospeševanju v prostem teku ali enakovrednimi postopki.
For petrol-fuelled mobile sources, the effectiveness of the control of emissions of PAHs (in addition to other exhaust components) may be ensured through programmes to test periodically the fuel metering and the efficiency of the catalytic converter. 
Pri premičnih virih z bencinskim motorjem se lahko učinkovitost nadzora nad emisijami PAH (poleg drugih sestavin izpuha) zagotovi s programi za občasno merjenje porabe goriva in učinkovitosti katalizatorjev.

General aspects of control technologies 
Splošno o nadzoru
It is important to ensure that vehicles are designed to meet emission standards while in service. 
Pomembno je zagotoviti, da so vozila zasnovana tako, da med uporabo izpolnjujejo standarde za emisije.
This can be done by ensuring conformity of production, lifetime durability, warranty of emission-control components, and recall of defective vehicles. 
To je mogoče zagotoviti z ustrezno proizvodnjo, obstojnostjo v celotnem življenjskem obdobju, jamstvom za sestavne dele, ki zmanjšujejo emisije, in izločitvijo neustreznih vozil.
For vehicles in use, continued emission control performance can be ensured by an effective inspection and maintenance programme. 
Stalen nadzor nad emisijami se za vozila v uporabi zagotovi z učinkovitim programom pregledov in vzdrževanja.
Technical measures for emission control 
Tehnični ukrepi za nadzor nad emisijami
The following measures to control PAH emissions are important: 
Pomembni so naslednji ukrepi za nadzor nad emisijami PAH:
(a) Fuel-quality specifications and engine modifications to control emissions before they are formed (primary measures); and 
(a) opredelitev kakovosti goriva in spremembe zasnove motorjev zaradi zmanjšanja emisij, preden nastanejo (primarni ukrepi), in
(b) Addition of exhaust treatment systems, e.g. oxidizing catalysts or particle traps (secondary measures). 
(b) namestitev sistemov za čiščenje izpušnih plinov, na primer oksidacijskih katalizatorjev ali lovilnikov trdnih delcev (sekundarni ukrepi).
(a) Diesel engines 
(a) Dizelski motorji
Diesel-fuel modification can yield two benefits: 
Sprememba dizelskega goriva ima lahko dve prednosti:
a lower sulphur content reduces emissions of particles and increases the conversion efficiency of oxidizing catalysts, and the reduction in di and tri-aromatic compounds reduces the formation and emission of PAHs. 
manjša vsebnost žvepla zmanjšuje emisije delcev in povečuje učinkovitost oksidacijskih katalizatorjev, zmanjšanje di- in triaromatskih spojin pa zmanjša nastanek in emisije PAH.
A primary measure to reduce emissions is to modify the engine to achieve more complete combustion. 
Eden od primarnih ukrepov za zmanjšanje emisij je sprememba zasnove motorja, da se doseže popolnejše zgorevanje.
Many different modifications are in use. 
Uporabljajo se raznovrstne spremembe.
In general, vehicle exhaust composition is influenced by changes in combustion chamber design and by higher fuel injection pressures. 
Na sestavo izpušnih plinov na splošno vplivajo spremembe v zasnovi zgorevalne komore in večji tlak pri vbrizgavanju goriva.
At present, most diesel engines rely on mechanical engine control systems. 
Danes se pri večini dizelskih motorjev uporabljajo mehanski sistemi krmiljenja motorja.
Newer engines increasingly use computerized electronic control systems with greater potential flexibility in controlling emissions. 
Pri novejših motorjih pa se vse pogosteje uporabljajo računalniško vodeni elektronski sistemi krmiljenja, ki omogočajo večjo prilagodljivost pri nadzoru nad emisijami.
Another technology to control emissions is the combined technology of turbocharging and intercooling. 
Druga možnost za nadzor nad emisijami je kombinirana tehnologija visokotlačnega polnjenja in vmesnega hlajenja.
This system is successful in reducing NOx as well as increasing fuel economy and power output. 
S tem sistemom se uspešno zmanjšuje NO(x) ter povečujeta varčna poraba goriva in izstopna moč.
For heavy and light-duty engines the use of intake manifold tuning is also a possibility. 
Pri motorjih z veliko in majhno prostornino je možno tudi spreminjanje geometrije sesalne cevi.
Controlling the lubricating oil is important to reduce particulate matter (PM), as 10 to 50% of particulate matter is formed from engine oil. 
Pri zmanjševanju emisij trdnih delcev (PM) so pomembni ukrepi v zvezi z mazivnim oljem, saj 10 do 50% trdnih delcev nastaja iz motornega olja.
