1. INTRODUCTION
Water contamination by radio nuclides, heavy
metals and industrial pollutants is a very important
problem in the world. Last years the phytotechnolo-
gies are used for contamination removal by plants.
The principal mechanism for contamination uptake
is sorption by roots [1]. The main mechanism in-
volved in biosorption is ion exchange between mono-
valent metals as counter ions present in macrophytes
biomass and heavy metal ion and protons taken up
from water [2]. A review of literature shows that
metals can be removed by inexpensive biological ma-
terials as algae, fungi and bacteria [3, 4].
In 2011 Pistia stratiotes has appeared in the waste
canal of thermal power station-2 which takes places
on the Seversky Donets river near the settlement Es-
har of the Kharkov region. The significant amounts of
Pistia stratiotes have been discovered in the Seversky
Donets river in 2013 year (Fig.1). The water temper-
ature in Seversky Donets river was 25.1◦C in July
2013. The temperature in the waste canal of thermal
power station-2 (0.5 km below the water discharge)
was 30.2◦C. Water plant of Pistia stratiotes is a plant
of warm water aquariums and botanic gardens from
tropical fields from Africa. The facts of the occur-
rence of this water plant in Europe are registered [5].
Most likely, this plant is brought in reservoirs from
decorative ponds and aquariums. The tropical water
plant has appeared in natural reservoirs of medial lat-
itudes for refining of city sewage, waste of factories,
enterprises of the textile industry. This water plant
is used also in a combination to other water plants
for sewage treatment of pig-breeding complexes.
The given water plant is a plant-introdutsent (im-
migrant). This plant grows and multiplies rapidly
and also intensively absorbs almost all biogenic ele-
ments and their compounds from water. Efficacy of
compound cleaning is ∼95%. The cleared water is
used for watering of agricultural crops.

Last years it is observed dilating of a geographic
range of diffusion and acceleration invasion processes
of Pistia stratiotes. It is promoted processes of warm-
ing of a climate observed in last year’s, and also
the thermal contamination of water objects. The
Pistia stratiotes can hibernate if water does not freeze
[6] in the winter.
Strong development of Pistia stratiotes can cause
of shadowing of the water areas of the river. In such
conditions the vegetation in the water will die off and
the hydrochemical state of the river, first of all an

oxygen regimen to worsen. It can cause local (or
mass) destruction of fish and other hydrobionts that
will lead to the further deterioration of river water.
The Pistia stratiotes is object of intensive study
because of a series of unique its properties. The Pistia
stratiotes produce a big amounts of Ca oxalate crys-
tals in specialized cells called crystal idioblasts [7]. It
has been determined that Ca2+ channels play a key
role in Ca oxalate crystal formation in this plants.

such radio nuclides, as 210Pb (∼25%), 232Th (∼30%),
228Th (∼20%), 238U (∼10%), 40K (∼2%), 226Ra
(∼2%), 228Ra (∼1.0%). Concentration of natural ra-
dio nuclides in the coals used on the Zmievsky state

Nuclear power plants (NPP) also cause releasing
of radioactive isotopes into the atmosphere (Table 2).
Thereupon some isotopes represent danger at incor-
poration into a human body. Owing to the high rate
of metabolic processes in children the 131I is espe-
cially dangerous. The transport of 131I through the
grass → cow → milk → man food chain is caused pri-
marily by the interception efficiency of typical pasture
vegetation for the radionuclide, the unique secretion
of iodine into milk by the cow, and the rapidity with
which milk is processed and reaches the consumer.
The aim of the present study is to investigate the
mechanism of the simultaneous removal of metals de-
rived from industrial activities from dead freshwater
macrophytes and the creation of a method of moni-
toring of 131I in biosphere by means of detection of
its activity in roots of Pistia stratiotes.
2. MATERIALS AND METHODS
Samples of Pistia stratiotes from the Seversky
Donets river were investigated. Samples Pistia
stratiotes were taken in October, 2013. Investigation
of radionuclide activity in dry native samples (roots,
leaf) of Pistia stratiotes was conducted using Ge(Li)-
detector with energy resolution of 3.2 keV at the en-
ergy of 1333 keV. Time of activity measurements of
samples weighing up to 0.5 kg was 6...12 hours. Nat-
ural isotopes – 40K, 235,238U, 232Th families, cosmic
– 7Be, and anthropogenesis - 137Cs and 131I were de-
tected in native samples. The errors of measurements
were from 3 to 25%. Activation of samples has been
conducted with use brake radiation of the linear ac-
celerator electrons NSC KIPT with electron energy
23 MeV and a current 500 µA. Activation of samples
was carried out on air, the temperature of samples in
the course of activation did not exceed 40◦C. Trace
elements Zn, Ni, Ca, I, Mn, Rb, Zr, Na and oth-
ers were determined. The limit of detection elements
for photoactivation analysis was 10−4...10−7wt. The
ashing of samples was spent at temperature 700◦C.
3. RESULTS AND DISCUSSION
In Fig.2 the γ-spectrum of the initial sample of the
leaf of Pistia stratiotes is presented. In γ-spectrum
of investigating sample the various elements are ob-
served (226Ra, 7Be, 214Pb, 208Tl, 137Cs, 40K and oth-
ers) (Table 3). Special interest causes 7Be (T1/2=53
days). 7Be is generated by cosmic rays in the up-
per troposphere and stratosphere, and is a tracer of
downward aerosol transport.

It is especially necessary to note detection 131I.
It arrives into the water of the river in the course of
deposition of aerosols of the working NPP. The high
coefficient of accumulation Pistia stratiotes iodine al-
lows to register isotope 131I (see Table 3). Consid-
erable quantity of iodine collects by roots of Pistia
stratiotes. Therefore the possibility of determination
of 131I by means of activity of Pistia stratiotes allows
to carry out radioiodine monitoring in an environ-
ment.
In Fig.3 the gamma spectrum of the irradiated
sample of root of Pistia stratiotes is given. A consid-
erable quantity of elements (Table 4) were registered.

The content of elements in the leaves and roots of
Pistia stratiotes from Seversky Donets has the singu-
larities. The Seversky Donets river is not pure. We
will note in Pistia stratiotes high enough concentra-
tions of essential elements of Ca and K. The content
of elements in roots of Pistia stratiotes is big due to
accumulation of conventionally essential elements of
Mn, Co, Ni, Mo and I. Also high value of accumula-
tion by roots of Pistia stratiotes toxic elements of Pb,
U and As.
The iodine content in roots of Pistia stratiotes
from the Seversky Doners river is ∼10−4 g/g. As-
suming that the coefficient of accumulation of iodine
by roots of Pistia stratiotes is ∼1000 it is possible
to estimate the iodine content in the water: ∼10−7
g/g [10]. In turn, it is possible to estimate the con-
tent of 129I and 131I. For Europe the attitude 129I/I is
∼10−6 [11]. Hence, the 129I and 131I contents in wa-
ter the Seversky Doners river were ∼10−13 g/g and
∼2 Bk/l, accordingly. The estimate of the content
of 137Cs in water is ∼10−3 Bq/l that coincides with
mean values in Ukraine [12]. The estimate of value of
the ratio of 137Cs/Cs is ∼10−8. The ratio 137Cs/Cs
for leaves of Pistia stratiotes is 27.8 Bq/mg. For ex-
ample, of the most polluted wood in Finland (Kul-
laa, 18.2 kBq/m2) the ratio 137Cs/Cs is 5100 Bq/mg
[13]. The difference between the ratios of 137Cs/Cs is
partly attributable to the different deposition levels
of 137Cs. A positive correlation between the total de-
position of 137Cs and the 137Cs/Cs ratio was observed
for the different sites. However, different concentra-
tions of stable Cs in soil and rivers (e.g. vegetation,
geology, soil type) also affect the 137Cs/Cs ratio.

Considerable calcium quantity is caused the for-
mation of compounds of type of KAlSi3O8, SiO2,
Fe2O3 and others which cause the formation of small
amounts of flying compounds [14]. That in turn is
the positive factor at use of Pistia stratiotes as an
absorption material for heavy metals, Sr, As and I.
4. CONCLUSIONS
1. The 131I activity of one of dangerous radioiso-
topes from NPP has been registered in roots of Pistia
stratiotes by γ-spectrometry.
2. Accumulation of Mn, Co, Ni, Mo, I, Pb and
isotopes 228Ac, 214Pb and 214Bi has been detected in
52
roots and leaves of Pistia stratiotes (their ratios were
counted).
3. Photoactivation analysis possesses advantages
at the determination of sorption of radioisotopes by
plants.
4. The developed methods allow carrying out ra-
dioisotopes monitoring in the biosphere.

Medvedeva, M.A. Botova, N.P. Khlapova, I.D. Fedorets // Вопросы атомной науки и техники. — 2014. — № 5. — С. 50-53. — Бібліогр.: 14 назв. — англ. 1562-6016 PACS: 89.60.-k https://nasplib.isofts.kiev.ua/handle/123456789/80478 The activity of leaves and roots of Pistia stratiotes from the Seversky Donets river has been measured. The visible activity of ¹³¹I in roots of plant is found. The content estimate of ¹³¹I in water of Seversky Donets river before extraction of samples of a hydrophyte gives value exceeding 1 Bk/l. The detection of activity of ¹³¹I in roots of Pistia stratiotes can be used for its monitoring in the biosphere. The photoactivation analysis has been used for measuring of element content in leaves and roots of Pistia stratiotes. Accumulation in roots versus leaves of Pistia stratiotes Mn, Co, Ni, Mo, I, Pb and also isotopes ²²⁸Ac, ²¹⁴Pb and ²¹⁴Bi was detected. Была измерена активность листьев и корней Pistia stratiotes из Северского Донца. Зарегистрирована заметная активность ¹³¹I в корнях растения. Оценка содержания ¹³¹I в воде Северского Донца перед извлечением образцов гидрофита дает значение, превышающее 1 Бк/л. Метод детектирования активности ¹³¹I в корнях Pistia stratiotes может быть использован для мониторинга его в биосфере. Фотоактивационный анализ был использован для измерения содержания элементов в листьях и корнях Pistia stratiotes из Северского Донца. Обнаружено накопление в корнях относительно накопления в листьях Pistia stratiotes Mn, Co, Ni, Mo, I, Pb, а также изотопов ²²⁸Ac, ²¹⁴Bi и ²¹⁴Pb . Була вимiряна активнiсть листя i корення Pistia stratiotes iз Сiверського Донця. Зареєстрована помiтна активнiсть ¹³¹I у коренях рослини. Оцiнка вмiсту ¹³¹I у водi Сiверського Донця перед витяганням зразкiв гiдрофiта дає значення, яке перевищує 1 Бк/л. Метод детектування активностi ¹³¹I у коренях Pistia stratiotes може бути використаний для монiторiнгу його в бiосферi. Фотоактивацiйний аналiз був використаний для вимiрювання вмiсту елементiв у листках i кореннях Pistia stratiotes iз Сiверського Донця. Виявлено накопичення в коренях вiдносно накопичення в листях Pistia stratiotes Mn, Co, Ni, Mo, I, Pb, а також iзотопiв ²²⁸Ac, ²¹⁴Bi і ²¹⁴Pb. en Національний науковий центр «Харківський фізико-технічний інститут» НАН України Вопросы атомной науки и техники Ядерно-физические методы и обработка данных Radionuclide biosorption by the aquatic plants of Pistia stratiotes Биосорбция радионуклидов водными растениями Pistiastratiotes Бiосорбцiя радiонуклiдiв водними рослинами Pistiastratiotes Article published earlier |
