1. ENHANCED REMOVAL OF PERSISTENT CONTAMINANTS AND TOXICITY REDUCTION THROUGH THE APPLICATION OF A TRIPLE-STAGE FENTON PROCESS TO SANITARY LANDFILL LEACHATES FROM YUCATAN, MEXICO
Sanitary landfill leachate (SLL) is a mixture of highly toxic and recalcitrant pollutants that threatens the water quality of the Yucatán Peninsula karst aquifer, one of the most extensive aquifers on the planet. To reduce the adverse environmental impacts of this wastewater, a triple-stage Fenton process (FP) was applied in an old SLL. Removal efficiencies

2. DETERMINATION OF TOTAL AND BIOACCESSIBLE ELEMENTS IN TEMPORARY ADHESIVE TATTOOS USED BY CHILDREN AND ADULTS
The presence of bioaccessible potentially-toxic elements in five different brands of temporary tattoos (packaged with bubble gums) aimed at children and three product brands used by young and adult audiences were analyzed in accordance with the Brazilian Organization of Technical Standards (ABNT) and International Organization for Standardization (ISO) for t

3. NEGATIVE EFFECTS ON PHOTOSYNTHESIS AND CHLOROPLAST PIGMENTS EXPOSED TO LEAD AND ALUMINUM: A META-ANALYSIS
ABSTRACT Toxic metals have become some of the main abiotic agents that influence the stress of organisms due to their numerous agricultural and industrial uses that result in bioaccumulation and toxicity at different levels, depending on the type and concentration in the environment. Aluminum and lead are present as a result of anthropogenic activities and c

4. MORPHOPHYSIOLOGICAL AND NUTRITIONAL BEHAVIOR OF Hymenaea stigonocarpa Mart. ex Hayne (FABACEAE) SEEDLINGS SUBMITTED TO LIMING
RESUMO A calagem é benéfica para as plantas por promover a elevação do pH, neutralização do alumínio tóxico, aumentar o fornecimento de cálcio (Ca²+) e magnésio (Mg²+) e propiciar maior sistema radicular. No entanto, sabe-se que as espécies, principalmente nativas do Cerrado, respondem de formas distintas a essa técnica. Diante do exposto, o ob

5. Sources and doses of aluminum in experiments with rice in nutrient solution
RESUMO Não é ainda bem definida a fonte de alumínio para gerar toxidez em experimentos de solução nutritiva com plantas de arroz, embora o sulfato de alumínio e potássio tem sido utilizado como fonte para gerar toxidez por alumínio. Entretanto, em publicações mais recentes, tem-se utilizado o cloreto de alumínio. Assim, o objetivo do trabalho foi

6. Evaluation of the embryotoxicity in zebrafish (Danio rerio) of the flocculant and coagulant compounds used for water remediation
Resumo Objetivo: O carreamento decorrente das atividades de mineração atinge corpos d'água, causando contaminação da água e acidificação por metais tóxicos. Como conseqüência, a depleção de oxigênio ocorre, com o desaparecimento de certos organismos bênticos, perdas na biomassa do fitoplâncton e do zooplâncton, e mortalidade de peixes. Rem

7. Avaliação química, ecotoxicológica e genotoxicológica de águas de cavas de mineração a céu aberto
RESUMO Lagos artificiais formados em áreas de mineração a céu aberto são unidades complexas e se constituem em passivos ambientais emergentes advindos da indústria da mineração. Embora estejam aumentando em número em várias partes do globo, são um problema ambiental recente e ainda pouco estudado, especialmente no tocante à qualidade e à toxicid

8. High concentrations of toxic metals in water consumed by the Maxakali indigenous community in Brazil
Resumo O povo Maxakali é a segunda maior população indígena aldeada no Estado de Minas Gerais, Brasil, tendo nas doenças infecciosas e parasitárias, sua principal causa de morte. Problemas com a qualidade da água consumida por essa população, somados à ausência dos serviços públicos de saneamento, agravam o risco de adoecimento por diversas pato

9. Anticorrosive Effect of PVP 40000 Against AISI 1020 Carbon Steel in HCl
Polymers have received considerable attention for replacing synthetic inorganic and organic anti-corrosion inhibitors since they are not as toxic for the environment, besides being cheaper. Polyvinylpyrrolidone (PVP) has been studied due to its applicability, solubility, very low toxicity, cost and efficiency in corrosion inhibition against metals, such as z

10. Chemical Species and Aluminum Concentration in the Solution of Acid Soils Cultivated with Soybean and Corn under Liming
ABSTRACT Chemical speciation of the soil solution is an important tool to identify Al species related to phytotoxicity. In some Brazilian acid soils, the Al extractable by the KCl 1.0 mol L -1 solution (Al-KCl) exceeds 10 cmol c kg -1 and even then, in some situations, it does not cause toxicity to the plants. This study aimed to evaluate the relationship be

11. Initial root length in wheat is highly correlated with acid soil tolerance in the field
ABSTRACT: In acid soils, toxic aluminum ions inhibit plant root growth. In order to discriminate aluminum (Al) tolerance, trustful screening techniques are required. In this study, 20 wheat cultivars, showing different levels of Al tolerance, were evaluated in a short-term soil experiment to access their relative root length (RRL). Moreover, the alleles of t

12. Effects of aluminum on the elongation and external morphology of root tips in two maize genotypes
ABSTRACT The objective of this study was to evaluate the effects of toxic levels of aluminum (Al) on the growth and external morphology of root tips in two maize genotypes with differential Al tolerance. The maize genotypes UFVM-100 (Al-sensitive) and UFVM-200 (Al-tolerant) were treated with 0 and 50 mM Al in a 0.5 mM CaCl2 solution at pH 4.5; root elongatio
