Scarzella has contributed to the understanding of heavy metal mobility, organic contaminant degradation, and the impact of industrial effluents on freshwater ecosystems. She has held academic appointments at multiple institutions, published extensively in peer‑reviewed journals, and served on national advisory committees related to environmental protection.
Early Life and Education
Family Background and Early Years
Elda Mazzocchi Scarzella was born on 12 March 1957 in the city of Bologna, Italy. She grew up in a family with strong academic ties; her father, Luigi Mazzocchi, was a professor of physics at the University of Bologna, while her mother, Carla Scarzella, taught chemistry at a local high school. The household environment encouraged scientific curiosity, with regular discussions about scientific developments and access to scientific literature.
Primary and Secondary Education
During her primary schooling at Liceo Scientifico “Galileo” in Bologna, Scarzella demonstrated an early aptitude for mathematics and chemistry. She consistently earned top grades and participated in regional science competitions, securing first place in a chemistry contest organized by the Italian National Institute of Physics in 1973. In 1974, she entered the same high school, where she completed the Scientific High School Diploma (Maturità Scientifica) with honors in 1975.
Undergraduate Studies
In 1975, Scarzella enrolled in the Faculty of Sciences at the University of Bologna, pursuing a Bachelor of Science degree in Chemistry. Her undergraduate coursework included analytical chemistry, organic synthesis, physical chemistry, and environmental science. Her senior thesis, titled “Spectrophotometric Determination of Lead in Water Samples,” was supervised by Professor Gianni Rossi and presented at the university’s annual scientific symposium in 1978. The project demonstrated her interest in environmental analytical methods and earned her the university’s Outstanding Thesis Award.
Graduate Training
After completing her bachelor's degree, Scarzella continued at the University of Bologna for a Master of Science in Analytical Chemistry. Her master's thesis, “Chromatographic Approaches for the Detection of Organic Micro‑Pollutants in Riverine Water,” explored advanced liquid chromatography techniques. The work contributed to the development of a rapid screening method for detecting trace levels of pesticides in river water, which later became a reference for environmental monitoring programs in Italy. She received her master's degree in 1980.
In 1981, Scarzella began her doctoral studies at the same institution under the guidance of Professor Maria Antonietta De Luca. Her Ph.D. research focused on the speciation and transport mechanisms of arsenic and mercury in freshwater systems. She employed a combination of field sampling, laboratory sorption experiments, and isotope dilution mass spectrometry. Her dissertation, “Mechanistic Studies of Trace Metal Mobility in River Sediments,” was awarded the University of Bologna’s Best Dissertation Prize in 1985.
Academic Career
Early Post‑Doctoral Positions
Following the completion of her doctorate, Scarzella accepted a post‑doctoral fellowship at the Italian National Research Council (Consiglio Nazionale delle Ricerche, CNR), where she worked from 1985 to 1987. Her research at CNR involved collaboration with the Department of Environmental Sciences, focusing on the development of bioassays for detecting endocrine‑disrupting compounds in surface waters. During this period, she co‑authored a series of papers that highlighted the ecological risks posed by bisphenol A and related chemicals.
Faculty Appointment at the University of Padua
In 1988, Scarzella joined the faculty of the University of Padua as an associate professor in the Department of Chemistry. Her appointment coincided with the creation of a new environmental chemistry laboratory dedicated to interdisciplinary research on water quality. She led graduate students and post‑doctoral researchers, expanding the laboratory’s scope to include studies on nanomaterials, heavy metal bioavailability, and microbial transformation of pollutants.
Promotion to Full Professor
Scarzella’s research output, coupled with her commitment to teaching, led to her promotion to full professor in 1996. In 2001, she was appointed chair of the Department of Chemistry, a position she held until 2010. During her tenure, she oversaw the expansion of the department’s research infrastructure, secured substantial external funding, and initiated a graduate program in Environmental Engineering and Chemistry.
International Collaboration and Visiting Positions
Scarzella’s international profile grew through her collaboration with research groups in the United States, United Kingdom, and Australia. She held visiting appointments at the University of California, Berkeley (1999), the University of Oxford (2003), and the University of Queensland (2007). These visits facilitated cross‑institutional studies on the long‑term fate of microplastics in freshwater ecosystems and the development of cost‑effective water treatment technologies.
Retirement and Emeritus Status
In 2015, Scarzella retired from her active faculty position and was granted emeritus status by the University of Padua. She continued to advise students, collaborate on research projects, and serve on editorial boards of scientific journals. Her emeritus years were marked by a focus on policy advisory work and the mentoring of early‑career scientists.
Research Contributions
Trace Metal Speciation and Mobility
One of Scarzella’s core research areas involved the detailed investigation of trace metal speciation in aquatic environments. She pioneered the use of X-ray absorption spectroscopy to elucidate the coordination chemistry of arsenic, mercury, and cadmium in river sediments. Her studies clarified the role of organic matter and sulfide minerals in mediating metal sorption and release, informing risk assessments for contaminated sites.
Development of Analytical Techniques
Scarzella contributed significantly to the advancement of analytical methodologies for environmental monitoring. She developed a rapid, portable spectrophotometric device capable of detecting nitrate, phosphate, and heavy metal ions in situ. The device’s low detection limits and ease of use made it suitable for field surveys in remote regions. Additionally, she refined high‑performance liquid chromatography protocols for the detection of pharmaceuticals and personal care products at sub‑nanomolar concentrations.
Assessment of Endocrine Disruptors
Collaborating with ecotoxicologists, Scarzella assessed the presence and ecological impact of endocrine‑disrupting compounds in European rivers. Her laboratory performed both chemical analyses and bioassays using zebrafish embryos and amphibian tadpoles. The findings provided empirical evidence that linked trace levels of bisphenol A to developmental abnormalities, influencing regulatory limits for this chemical in the European Union.
Remediation Strategies for Contaminated Water Bodies
Scarzella explored sustainable remediation techniques for polluted water bodies. She investigated the use of phytoremediation plants, such as willow and poplar, to extract heavy metals and organic pollutants from contaminated soils and water. Her work demonstrated that these plants could accumulate significant concentrations of arsenic and mercury, thereby reducing the overall contaminant burden in affected areas. She also evaluated the use of constructed wetlands for the removal of nitrate and phosphates from agricultural runoff.
Nanomaterials in Water Treatment
In the early 2010s, Scarzella’s research shifted toward the application of nanomaterials in water treatment. She studied the synthesis of iron‑oxide nanoparticles functionalized with chitosan to enhance adsorption of lead and cadmium ions. Her studies revealed high removal efficiencies (>90%) and suggested scalable production methods for use in municipal water treatment facilities.
