2. Ocular tentacle malformation in Deroceras reticulatum (Mollusca: Gastropoda: Agriolimacidae)
Abstract Malformations in animals have long been known. In gastropod, natural and induced malformations are mentioned in different systems and in ocular tentacles, mainly linked to cases of parasitism and exposure to pollutants (molluscicides and chemicals). In this study we present a new malformation not documented in the ocular tentacles of slug Deroceras

3. Tunnel vision in current chemicals management cannot deal with the unknown risk of synthetic chemicals in aquatic systems
Resumo A gestão e o manejo de poluentes químicos são focados na periculosidade, exposição e avaliação de risco. Esse processo é lento e não acompanha o surgimento de novas substâncias e o desenvolvimento do seu uso. O monitoramento ambiental foca em poucas substâncias que são bem conhecidas. Consequentemente, a maioria das substâncias emitidas

6. Oxidative stress and histopathologic biomarkers of exposure to bisphenol-A in the freshwater fish, Ctenopharyngodon idella
ABSTRACT Bisphenol-A (BPA) belongs to the family of endocrine disrupting chemicals (EDCs) and it is used in the production of polycarbonate plastic and epoxy resins. The reproductive toxicity of BPA is well documented but it also exerts its toxic effects through multiple pathways especially by inducing a state of oxidative stress and causing damage to the vi

8. Genotoxic effect of Phenanthrene on Chironomus sancticaroli (Diptera: Chironomidae)
Phenanthrene, a Polycyclic Aromatic Hydrocarbon, remains adsorbed to sedimentary particles in aquatic environments. It affects mainly benthic organisms, and is considered potentially genotoxic. In ecotoxicology, species of Chironomus Meigen, 1803 are widely known as bioindicators of the effects of chemicals on aquatic organisms. This study investigates the e

9. Genotoxicity of Nicotiana tabacum leaves on Helix aspersa
Tobacco farmers are routinely exposed to complex mixtures of inorganic and organic chemicals present in tobacco leaves. In this study, we examined the genotoxicity of tobacco leaves in the snail Helix aspersa as a measure of the risk to human health. DNA damage was evaluated using the micronucleus test and the Comet assay and the concentration of cytochrome

10. Avaliação da concentração de elementos químicos tóxicos na merenda escolar de crianças da cidade de Ribeirão Preto e estimativa de suas ingestões diárias / Assessment of toxic chemicals concentration in the school
Chemical\ s contamination in the environment is a growing worldwide problem. Many of these chemical elements, including Cd, Pb and As are toxic to humans. According to the World Health Organization (WHO), 90% of the intake of these toxic elements occurs through the food consumption (Tavares et al., 1992; Virga et al., 2007). Therefore, the estimation of expo

12. Morfofisiologia do sistema genital masculino de ratos púberes e adultos após privação androgênica durante a pré-puberdade / Morphophysiology of male reproductive system of adult and pubertal rats after androgen deprivation during prepuberty
Endocrine disrupters are chemicals that can act as agonists or antagonists of endogenous hormones, interfering with the homeostasis of the organism. Since the endocrine system plays a critical role in the development and function of the male reproductive system, this is an especially vulnerable target of potential endocrine perturbations. The literature pres
