Submission Guidelines

8^th Brazilian Meeting on Chemical Speciation 2025

Guidelines for Abstract Submission

Abstracts must be submitted online in the Participant Area of the official homepage by October 1st, 2025. Each participant is allowed to submit a total of 01 abstract.

• Prepare the abstract in English according to the MS Word document – download the template.
• The abstract may not exceed one page.
• For abstracts selected by the Scientific Committee, oral presentations must be in English.

Submitted abstracts must be relevant to one of the RESEARCH TOPICS below:

1. Speciation and Fractionation in the Environment

Studies on chemical speciation, fractionation, and bioavailability of elements in water, soils, and sediments, assessment of ecological risks and contaminant mobility in natural environments. Research on speciation and chemical fractionation applied to biogeochemical processes.

2. Speciation and Fractionation Analysis in Life and Pharmaceutical Sciences

Studies on chemical speciation and fractionation in biological systems, metal-protein interactions, chemical speciation in diseases, and the impact of speciation on bioavailability and toxicity. Research on chemical speciation and fractionation in pharmaceuticals. Speciomics.

3. Speciation and Fractionation in Nutrition and Food Sciences

Studies on chemical speciation and fractionation in food and their bioavailability, the impact of chemical speciation and fractionation on human and animal nutrition, including the toxicity and benefits of specific mineral forms.

4. Speciation and Fractionation in Industrial and Mining Processes

Studies on speciation, chemical fractionation, and element mobility in industrial processes, mining, water treatment, and energy production. Waste management, recycling of critical metals, and controlling contaminant emissions.

5. Advances in Analytical Techniques and Sample Preparation for Chemical Speciation and Fractionation

Development of methods and application of analytical techniques (e.g., ICP-MS, HPLC-ICP-MS, XAS, and DGT) for fractionation and speciation analysis. Analytical methodologies for sample preparation and analysis in chemical speciation and fractionation across various sample types.

6. Emerging Topics in Chemical Speciation and Isotope Analysis

Chemical speciation and fractionation of nanomaterials, microplastics, and emerging contaminants. Monitoring and risk assessment of new organic and inorganic species and their chemical interactions with biotic or abiotic factors. The impact of climate change on the biogeochemical cycles of elements and chemical speciation. Speciation and fractionation under extreme experimental or environmental conditions, such as polar regions, volcanic zones, or deep marine environments. Applications of speciation in renewable energies. Innovative isotopic techniques, in situ and real-time speciation. Speciation in molecular modeling and bioinformatics. Chemical speciation using synchrotron radiation. Synthesis and application of organometallic species.

Poster size and language

The Organizing Committee of the 8^th EspeQBrasil have stated that posters must be restricted to a size measuring 90 cm wide x 120 cm high and be prepared in English.

Oral Presentations 

Participants with oral or flash poster presentations must present themselves to the room monitor at least 30 minutes before the start of the session in which they will participate. Abstracts selected for oral presentation must also be presented as posters.
