EVALUATION OF OXIDATIVE/NITROSATIVE STRESS BIOMARKERS IN KIDNEY, HEART AND MUSCLE TISSUES OF Oncorhynchus mykiss (WALBAUM, 1792) TREATED WITH MERCURY CHLORIDE (HgCl2)

The widespread presence of mercury (Hg) and its derivatives in aquatic environments necessitates the investigation of their toxic effects on fish and the potential risks they pose to the health of local populations. The objective of this study was to investigate the toxic effects of mercury chloride (HgCl2) on Oncorhynchus mykiss (Walbaum. 1792) by examining the dynamics of oxidative and nitrosative stress in muscle, kidney, and heart tissues. The rainbow trout used in the study had an average weight of 125.65±8.30 g. Five experimental groups were created, including a control group and groups exposed to 25% LC50 concentration of HgCl2 for 7 and 14 days, as well as groups exposed to 50% LC50 concentration of HgCl2 for 7 and 14 days. A total of 120 fish, with 40 fish assigned to each tissue (muscle, kidney, and heart), were used in the study. To evaluate oxidative/nitrosative stress, various parameters including ONOOˉ, TOS, TAS, OSI, and MDA levels were measured. Statistical analysis revealed a significant difference between the experimental groups in terms of TAS, TOS, OSI, ONOOˉ, and MDA levels in all three tissues (muscle, kidney, and heart) (P<0.05). In conclusion, the findings of this study demonstrate that HgCl2 induces stress and toxicity in rainbow trout, as evidenced by increased levels of MDA and ONOOˉ, which are stress indicators in the fish.

ESTABLISHING THE FIRST DATABASE OF SOIL HYDRAULIC PROPERTIES IN TUNISIA BASED ON PEDOTRANSFER FUNCTIONS

Soil hydraulic properties play a crucial role in the unsaturated soil water supply process. Currently, Tunisia lacks a database containing essential values for soil retention properties and soil saturated hydraulic conductivity. The main objective of this study is to create the inaugural soil hydraulic properties database through the utilization of open-access data and pedotransfer functions (PTFs). To achieve this goal, the harmonized world soil database (FAO) was employed to identify 752 measurement points across Tunisia. Subsequently, the soil texture, organic carbon content, and bulk density were determined at each point. These acquired values were then entered into the CalcPTF software to estimate the van Genuchten soil retention parameters. The calculation of soil saturated hydraulic conductivity was accomplished using two widely recognized pedotransfer functions (Saxton and Rosetta). The outcomes facilitated the creation of a catalog containing soil hydraulic parameter value for each soil texture. Significance of discrepancies between values obtained from the PTFs was assessed using a Tukey test. The spatial variability of each soil hydraulic property was studied using the simple kriging. In conclusion, the establishment of this significant soil hydraulic properties database holds diverse applications in agricultural, hydrological, and environmental studies in Tunisia.

ENVIRONMENTAL ASSESSMENT OF POLLUTION IN AN INDUSTRIAL ENVIRONMENT USING HEAVY METAL POLLUTION INDICES AND STABLE ISOTOPES, CASE STUDY OF THE INDUSTRIAL ZONE OF SKIKDA, NORTH-EAST ALGERIA

An environmental assessment study was conducted in the industrial area of Skikda in the Northeast of Algeria which involved physicochemical parameters, heavy metal concentrations, and stable isotopes of surface water, groundwater, and soil. The results revealed high concentrations of Cd, Ni, Fe, Cu, As, Cr, Pb, Co, and Mn in groundwater. The southern part exhibited the lowest heavy metal concentrations, while the industrial zone in the North contained the highest levels. Therefore, the industrial area showed significant pollution in groundwater by Cr, Pb, and As with respectively 0.5, 0.69, and 0.44 mg/l, surpassing the respective WHO(World Health Organization) standards of 0.05, 0.01, and 0.01 mg/l. Spatial analysis showed that the industrial area presents higher concentrations of As, Cr, Cd, Pb, Cu, Zn, Ni, and Fe which demonstrated similar trends in spatial distribution, their concentrations increasing within the industrial zone. However, the western part had no significant pollution sources except for a public landfill and SONATRACH industrial complex, high concentrations of Co and Mn in the south and the west parts were observed. Mean concentration in soils indicated that Cd is ranged between35.32 to 95.12 ppm, for Fe between 145.1 and 702 ppm, As varies between 1.03 and 81.85 ppm, and Zn between 50 and 520.32 ppm and considered as dominant metals. However, Mn, Co and Cr were lower respectively with 1.97, 12.11 and 7.25 ppm. Cd and As were most influenced by the polluting companies, while Cr was mainly influenced by natural factors, such as pH and soil type. Based on the contamination degree index, the soil pollution levels of Cd, Pb, and As were classified as extremely contaminated. The statistical analysis indicated substantial anthropogenic contributions to groundwater contamination concentrated in the industrial area. The groundwater exhibits a range of δ18O and δ2H values, varying from 2.45 to -5.33‰ and 19.82 to -1.67‰ vs. the V-SMOW (Vienna-Standard Mean Ocean Water) standard, respectively. The mean isotopic composition is -2.50‰ for δ18O, -19.32‰ for δ2H, with a mean deuterium excess of 6.45. These values align with the Meteoric Water Line observed in the western Mediterranean region. It indicates a hydrological connection between recharge and groundwater which suggests a significant interaction between groundwater and surface water. Due to their proximity to the river and the shallow aquifer, the downstream area is more vulnerable to surface pollution. Furthermore, the young groundwater in the downstream can be attributed to the rapid recharge and replenishment of the aquifer caused by rainfall and quick infiltration and sustained by the shallow aquifer depth and sandy soil. Consequently, the rainwater and industrial wastes lead to faster pollutant infiltration. Anthropogenic sources, including industrial effluents from smelting, refining, manufacturing, steel and textile industries, electroplating, nickel-cadmium battery production, welding, PVC product and paint pigment manufacturing, were identified as major contributors to heavy metal pollution.

NAMBULITE AND NATRONAMBULITE OCCURRENCE IN THE MANGANESE BELT, BISTRIŢA MOUNTAINS,EASTERN CARPATHIANS, ROMANIA

Nambulite, (Li,Na)Mn4Si5O14(OH), and natronambulite, (Na,Li)(Mn,Ca)4Si5O14(OH), occur in many deposits of Manganese Belt (MnB) in Bistriţa Mountains, Eastern Carpathians, Romania. The nambulite and natronambulite form small bands which cut the old bands/lens of braunite-bixbyite-hausmannite ore. Nambulite has Li>Na and forms a series with natronambulite. The natronambulite has Na>Li and Mn>Ca. The X-ray analyses of MnB nambulite showed that it crystallizes in triclinic system, space group Pī(2). Its unit cell parameters are: a=7.5300 Å, b=11.7360 Å, c=6.7100 Å, Z=2, V=565.00 Å3, α=92.97°, β=95.23°, and γ=106.27°. The natronambulite has: a=7.6200 Å, b=11.7620 Å, c=6.7370 Å, Z=2, V=574.436 Å3, α=92.81°, β=94.55°, and γ= 106.87°. The cell parameters of natronambulite are very close to those of nambulite. The chemical compositions of nambulite and natronambulite of MnB deposits were determined by SEM and wet chemical analyses. Their Li2O and Na2O were determined by AAS and by wet chemical analyses. The wet chemical analyses of nambulite show variation for Li2O=1.05-1.34 wt.% and Na2O=1.28-0.72 wt.%. The natronambulite has Li2O< Na2O, and higher Na2O and CaO contents than nambulite. In natronambulite the Li2O content varies between 0.45-0.65 wt.% and that of Na2O between 1.10-5.96 wt.%. The main MnO compound for both minerals has variations between 38.20-46.01 wt.%, where Mn cations have minor substitutions with Mg, Ca, Ni and Zn. The mineral textural relations show that the oldest mineral of ore is braunite, closed associated with bixbyite/hausmannite. The braunite is cut/substituted by the new nambulite and natronambulite, which in their turn are substituted by leakeite and holmquistite, respectively. Both minerals are closely associated with aegirine and albite. A wide range of many minerals, some of them unusual and new for Romania, occur as veins through the nambulite/natronabulite associations: jacobsite-Q, namansilite, lithiomarsturite, serandite, hematophanite, fairfieldite, yoshimuraite, imandrite, and others. Also, many common minerals like magnetite, hematite, spessartine, albite, microcline, barium feldspars, barite, nickelian phlogopite/kinoshitalite, and others occur. The mineralogy, geochemistry, and tectonically setting of Mn deposits showed their hydrothermal submarine origin related to subduction processes. The source of Li was not from external supply.

ASSESSMENT OF THE POTENTIALLY TOXIC ELEMENTS CONTAMINATION AND THEIR UPTAKE BY AMBROSIA ARTEMISIIFOLIA L. IN SOILS IN THE NORTHERN PART OF BOSNIA AND HERZEGOVINA

This research focused on the determination of potentially toxic elements (PTEs) distribution in different agricultural soils and Ambrosia atremisiifolia L. (ragweed) at seven, different locations in the northern part of Bosnia and Herzegovina (BiH). Quantification of PTEs was done using atomic absorption spectrophotometry provided after acid digestion of the air-dried samples of soil and plant material. Determined content of elements in the soils increased as follows: Cd<Pb<Cu<Zn<Cr<Ni<Mn<Fe and were under the allowed maximum for unpolluted soils, except for Ni and Cr. However, transfer of Ni and Cr from the soil to the ragweed as well as their bioaccumulation was not intensive. Established metal contents ratio from plant tissues (root and shoot) to soil for both elements, represented their bioaccumulation factors (BAF), which were extremely low in the roots, as well as in the shoots, both in average less than 0.2. On the other hand, Zn showed a tendency to accumulate in ragweed shoots (BAF=2.07). The study showed that uptake and accumulation of PTEs in the ragweed was mainly influenced by their content in the soil, as well as specific characteristics and biological role of each element. Hence, content of PTEs in the ragweed tissue could be used as the soil contamination degree indicator.
