Speciation of arsenic and concentration of cadmium and arsenic in rice (Oryza sativa L.) cultivated under co-exposure of cadmium/arsenic and different water ponding

Tatiana Pedron; Valmir Silva; Fernanda Pollo Paniz et al.

Journal of Trace Elements and Minerals, Vol. 12 · 2025 · English · DOAJ Scopus

Over three billion people consume rice (Oryza sativa L), an important cereal in the human diet. It is cultivated typically in flooded soils. However, it is also grown in soils with limited water (upland or dryland). There are few studies on the concomitant translocation of As and Cd from soil to…

Potentially Toxic Elements in Costume Cosmetics Used by Children and Adults Are Associated with Cancer Risk

Salles, Fernanda Junqueira; Paniz, Fernanda Pollo; Batista, Bruno Lemos et al.

Int J Environ Res Public Health · 2022 · English · PubMed Central

(1) Background: Costume cosmetics, such as face paints and pancakes, are used by adults and children during Halloween, Carnival, or children’s parties. However, the metallic-based pigments used as dyes in these products may contain toxic elements associated with different levels of exposure…

Selenium Biofortification Enhanced Grain Yield and Alleviated the Risk of Arsenic and Cadmium Toxicity in Rice for Human Consumption

Paniz, Fernanda Pollo; Pedron, Tatiana; Procópio, Vitória Aparecida et al.

Toxics · 2023 · English · PubMed Central

Arsenic (As) and Cadmium (Cd) are toxic to rice plants. However, selenium (Se) has the potential to regulate As and Cd toxicity. The present study aimed to evaluate the co-exposure to As(5+) and Se(6+) species in two rice cultivars, BRS Pampa and EPAGRI 108. The plants were divided into six groups…

A high-throughput analytical tool for quantification of 15 metallic nanoparticles supported on carbon black

Felipe de Moura Souza; Fernanda Pollo Paniz; Tatiana Pedron et al.

Heliyon, Vol. 5 No. 3 · 2019 · English · DOAJ Scopus

Metallic nanoparticles (NPs) have been widely used in different areas of science. Usually, they are immobilized on a low-cost support for catalysis purposes. However, there is a lack of studies for specific methods for analytical quantification since the extraction of these metallic NPs from the…

Lead, Cadmium, and Arsenic Bioaccessibility of 24 h Duplicate Diet Ingested by Preschool Children Attending Day Care Centers in Brazil

Leroux, Isabelle Nogueira; Ferreira, Ana Paula Sacone da Silva; Paniz, Fernanda Pollo et al.

Int J Environ Res Public Health · 2018 · English · PubMed Central

Lead, known as a metal with high neurotoxicity to children, cadmium, which is a carcinogenic and bioaccumulative contaminant, and arsenic, a class 1 carcinogenic according to the International Agency for Research on Cancer, are toxic elements (TEs) whose relevant route of exposure may be diet. We…

Is the genetic variability of elite rice in southern Brazil really disappearing?

Carlos Busanello; Eduardo Venske; Cássia Fernanda Stafen et al.

Crop Breeding and Applied Biotechnology, Vol. 20 No. 2 · 2020 · English · DOAJ Scopus

There is a worldwide concern about a possible narrowing of the genetic base of most crops, as e.g. that of rice (Oryza sativa L.), as a result of the modern breeding practices. Thus, the purpose of this study was to investigate this phenomenon in the germplasm of elite paddy rice in southern…

Genome-wide association of iron content in rice grains grown in Southern Brazil

Victoria Freitas de Oliveira; Eduardo Venske; Cássia Fernanda Stafen et al.

Pesquisa Agropecuária Brasileira, Vol. 58 · 2023 · Portuguese · DOAJ Scopus

Abstract The objective of this work was to map the chromosomal regions responsible for iron accumulation in rice grains, in Southern Brazil. Eighty-one rice accessions were genotyped and phenotyped for Fe accumulation. Single nucleotide polymorphisms were mapped in the whole grain on chromosomes 1…
