Abstract

Teški metali jedni su od najčešćih onečišćivala okoliša. Njihovi izvori mogu biti prirodnog
ili antropogenog podrijetla. Jedan od antropogenih izvora teških metala u okolišu je
željeznički promet čiji brzi razvoj i učestale linije u sjeverozapadnoj Hrvatskoj dovode do
onečišćenja tla te do njihove akumulacije u biljkama uz željezničku prugu. Metal kositar i
polumetal antimon u željezničkoj i transportnoj industriji koriste se u proizvodnji legura te
kao premaz za kočnice, što su mogući izvori ovih teških metala u tlu. Cilj ovog rada je
analizirati koncentracije kositra i antimona u tlu i biljkama uz željezničku prugu na području
sjeverozapadne Hrvatske. Tijekom lipnja i srpnja 2014. godine sakupljeni su uzorci tala i
biljnog materijala na 60 lokacija. Koncentracije kositra i antimona određene su pomoću
tehnike masene spektrometrije visoke rezolucije s induktivno spregnutom plazmom.
Koncentracije ovih metala određene su u tlima različitih granulometrijskih sastava te u osam
vrsta biljaka koje su česte na tom području. Raspon koncentracija kositra u tlu iznosi 3,04 –
97,64 mg/kg, dok za antimon te vrijednosti iznose 0,98 – 51,98 mg/kg. Pokazalo se da su
najonečišćenije postaje one glavne na kojima najčešće dolazi do usporavanja i ubrzavanja
vlakova te na kojima je najučestaliji promet, a to su Zaprešić, Varaždin i Žeinci. S druge
strane, zabilježene su koncentracije kositra u biljkama u rasponu od 0,037 do 6,172 mg/kg,
dok za antimon one iznose od 0,008 do 1,202 mg/kg. Pokazalo se da je od osam uzorkovanih
biljnih vrsta ambrozija (Ambrosia artemisiifolia) akumulirala najveće količine kositra i
antimona.

Abstract (english)

Heavy metals are one of the most frequent environmental pollutants. They come from natural
or anthropogenic sources. One of anthropogenic sources of heavy metals in the environment
is railway transport whose rapid development and frequent traffic in northwest Croatia leads
to environmental pollution and accumulation of metals in plants along the railway line. Metal
tin and metalloid antimony are used in railway and transport industry for the production of
alloys and as coatings on brakes, which are possible sources of these heavy metals in soil.
The main goal of this thesis is to analyse concentrations of tin and antimony in soil and plants
along the railway line in northwest Croatia. During June and July 2014 soil samples and plant
material were collected at 60 sites. Concentrations of tin and antimony were determined using
High Resolution Inductively Coupled Plasma Mass Spectrometry. Their concentrations were
determined in soils of different granulometric compositions and in eight species of plants that
are commonly found in the researched area. The range of tin concentrations in soil was 3,04
– 97,64 mg/kg and for antimony 0,98 – 51, 98 mg/kg. The results showed that the most
polluted sites were the ones at the main train stations where slowdowns and accelerations
happen most frequently and at the sites with heavy traffic, like Zaprešić, Varaždin and Žeinci.
On the other hand, recorded concentrations of tin in plants were 0,037 – 6,172 mg/kg and
antimony values ranged from 0,008 to 1,202 mg/kg. It was also determined that out of eight
sampled plant species, ambrosia (Ambrosia artemisiifolia) accumulated the largest amounts
of tin and antimony.
