80 Years of Excellence

Chemistry-Biology Faculty of Ternopil National Pedagogical University

From Foundations to Innovations

In the heart of Western Ukrainian education, in Ternopil, for more than eight decades, a scientific and pedagogical center has been thriving, preparing nature defenders, life and substance researchers, and teachers of future generations - the Chemistry-Biology Faculty of Ternopil National Pedagogical University named after Volodymyr Hnatyuk.

The faculty's anniversary is not just a tribute to the past but an opportunity to appreciate its relentless progress forward. This is a story of how fundamental knowledge in chemistry and biology intertwines with pedagogy to solve modern environmental challenges, develop biotechnologies, and educate new scientists.

History: A Foundation Strengthened Through Challenges

1945

Founded in the difficult post-war years as a natural sciences faculty, it became a center for the revival of education and science in the region.

Early Challenges

The first steps were difficult: lack of equipment, premises, and qualified personnel. However, the enthusiasm of the first teachers and students gave impetus to development.

Name Change

The name "Chemistry-Biology" appeared later, clearly defining its profile. The faculty evolved from training chemistry and biology teachers to becoming a scientific center with strong research traditions in biochemistry, plant physiology, ecology, organic and analytical chemistry.

Important Milestone

The university was named after the outstanding Ukrainian ethnographer Volodymyr Hnatyuk, emphasizing the connection with national cultural heritage.

Chemistry

Strong traditions in organic and analytical chemistry research.

Biology

Pioneering work in plant physiology and biochemistry.

Modern Equipment

The faculty laboratories are equipped with modern equipment: spectrophotometers, chromatographs (HPLC, GC), PCR amplifiers, high-resolution microscopes, opening wide opportunities for research.

In Focus: Heavy Metal Phytoextraction Experiment

The Threat

Soil contamination with heavy metals (lead, cadmium, zinc) near industrial zones or highways is a serious environmental problem that threatens human health and ecosystems.

The Solution

Using hyperaccumulator plants to remove metals from soil - phytoextraction.

Experiment Methodology

Clean control soil was taken. Soil batches were artificially contaminated with solutions of lead (Pb(NO₃)₂) and cadmium (CdCl₂) salts to concentrations of 100 mg/kg (Pb) and 20 mg/kg (Cd) - levels characteristic of moderately contaminated areas.

Seedlings of willow (Salix viminalis), sunflower (Helianthus annuus), and tobacco (Nicotiana tabacum) - species known for their potential metal accumulation ability - were planted in pots with contaminated and control soil.

After the vegetation period, plants were collected, the root system was thoroughly washed. Plants were divided into roots, stems, and leaves.

Concentrations of Pb and Cd in the obtained solutions were determined by atomic absorption spectroscopy (AAS). This method is extremely accurate for determining low metal concentrations due to the absorption of light of a specific wavelength by analyte atoms.

Results and Analysis

The key indicator of phytoextraction efficiency is the biological accumulation coefficient (BAC) - the ratio of metal concentration in the plant to its concentration in the soil.

Table 1: Metal concentrations in soil after experiment
Soil Type Initial Pb (mg/kg) Final Pb (mg/kg) Initial Cd (mg/kg) Final Cd (mg/kg)
Control (clean) < 5 < 5 < 0.5 < 0.5
Contaminated (Before) 100.0 ± 5.0 - 20.0 ± 1.0 -
Contaminated (After - Willow) 100.0 ± 5.0 82.3 ± 4.1 20.0 ± 1.0 15.1 ± 0.8
Contaminated (After - Sunflower) 100.0 ± 5.0 88.7 ± 4.4 20.0 ± 1.0 17.5 ± 0.9
Contaminated (After - Tobacco) 100.0 ± 5.0 91.5 ± 4.6 20.0 ± 1.0 18.2 ± 0.9
Key Findings
  • All plant species reduced metal content in soil
  • Willow was most effective for removing both metals
  • Maximum metal accumulation occurs in roots and leaves
Experiment Significance

This research clearly demonstrates the practical potential of phytoremediation - an environmentally friendly and economically beneficial method for cleaning contaminated areas.

Researcher's Toolkit

Essential reagents and materials for phytoremediation research:

  • Lead nitrate (Pb(NO₃)₂): Source of lead ions (Pb²⁺) for artificial soil contamination
  • Cadmium chloride (CdCl₂): Source of cadmium ions (Cd²⁺) for artificial soil contamination
  • Nitric acid (HNO₃, conc.): Mineralization of biological samples
  • Atomic absorption spectrophotometer (AAS): High-precision instrument for determining metal concentrations in solutions

Future Perspectives: The Future Laid Today

The Chemistry-Biology Faculty of TNPU looks to the future with optimism and ambitions:

Deepening Research

Integration of modern molecular biology methods (genomics, proteomics), nanotechnologies and artificial intelligence for data analysis in biochemical and environmental research.

Expanding Biotechnology

Development of areas related to the creation of biological preparations for agriculture, medicine (search for new antioxidants, antimicrobial substances from plants), biomass processing.

Ecology & Sustainability

Development of practical recommendations for the rehabilitation of disturbed ecosystems, monitoring of climate changes at the regional level, implementation of circular economy principles.

Modernizing Education

Active implementation of digital educational platforms, distance formats, project-based learning aimed at developing practical skills and critical thinking in students.

Conclusion: A Living Organism of Knowledge

80 years is an age of wisdom and experience for the Chemistry-Biology Faculty of TNPU named after V. Hnatyuk. From post-war reconstruction to today's challenges, the faculty has always been and remains a living organism that is constantly evolving.

Its strength lies in the combination of deep fundamental knowledge, applied research aimed at solving real problems of the region and the country, and the unchanging mission - to train highly qualified specialists, teachers and scientists.

The anniversary is not only a summary but also a start into a new era of innovations, when biology and chemistry become keys to solving humanity's most complex tasks. The future of the faculty is the future of science, education and environmental safety of Ternopil region and Ukraine.
