(1)EVOLUÇÃO NO TEOR DE CONTAMINANTES NO ARROIO DAS LAVRAS, EM LAVRAS DO SUL - RS. Gabriel Smith Nunes da Silva 1 Thayanne Barbosa Teixeira 2 Jauna Marilise do Nascimento Riegel 3 Cristiane Heredia Gomes 4. Resumo: Este trabalho objetivou na análise do histórico de contaminantes presentes nos corpos d'água através dos sedimentos de corrente do município de Lavras do Sul - RS. O histórico comparativo foi dado pela comparação entre a amostragem extraída pela equipe para realizar este projeto juntamente com a amostragem publicada a 10 anos atrás por Grazia et. al 2008. Na busca em relacionar as amostras com os valores orientadores da CETESB, este trabalho resultou em relatar e discutir a respeito do possível desenvolvimento regressivo nos teores de elementos que geram comportamentos lesivos ao meio ambiente. Foram correlacionado 3 elementos presentes nos sedimentos de corrente em áreas contempladas pelo Complexo Intrusivo Lavras do Sul (rochas graníticas) entre a análise realizada por Grazia (2008) e a análise geoquímica presente neste artigo (2018). As atividades em questão foram elaboradas e aplicadas por estudantes de Geologia, supervisionados pela professora Dra. Cristiane Heredia Gomes, ambos da Universidade Federal do Pampa, campus Caçapava do Sul.. Palavras-chave: Contaminantes, arroio, análise geoquímica. Modalidade de Participação: Iniciação Científica.
