Multivariate Analysis was used, and quality indexes were obtained, such as the Trophic State Index and the Water Quality Index for Aquatic Life Protection. River samples were collected at 4 points along the  Rio Verde for 12 months. The study showed that the river presents a high trophic degree, and that it can be considered hypereutrophic, and that phosphorus concentration is determinant for this situation. The results indicated that, at point 4, downstream from the Sewage Treatment Plant, the aquatic environment is very poor for the biota. The disposal of the effluent was indicated as the cause, and it is assumed that the river has no flow capacity  to receive this contribution, without suffering impact. It was also concluded that points 1 and 2 correspond to more preserved sites, but are not totally favorable to aquatic life either because they receive surface drainage from agricultural areas in the basin. Point 3, of urban character, suffers an impact caused by irregular connections of sewers, and contribution of streams that flow into the river.","PeriodicalId":11506,"journal":{"name":"Eclética Química Journal","volume":"49 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73571307","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aiming at the degradation of the contaminants present in the environment, treatments by advanced oxidative processes are based on the synthesis of free radicals that allow the degradation of the pollutant. Among these processes are included UV/H2O2. By evaluating the ecotoxicity and phytotoxicity of the commercial Malathion® 500 CE product, using Aedes aegypti larvae and Lactuca sativa seed, the high toxicity of this formulation was observed. EC50 values for A. aegypti being equal to 0.4 μg L-1 and for L. sativa equal to 550 μg L-1. The commercial agrochemical degradation was carried out by UVC radiation and UV/H2O2, and the toxicity was evaluated after 30 and 120 minutes. After both treatments, the percentage of immobility was zero for A. aegypti, inferring the efficiency of the processes. However, for L. sativa, no treatment was able to remove or reduce initial toxicity.","PeriodicalId":11506,"journal":{"name":"Eclética Química Journal","volume":"37 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91158635","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The city of Paranaguá, located at the coast of the Paraná State in Brazil, hosts the largest bulk cargo port in Latin America and an elevated number of fertilizer processing industries. In this study we used tree barks coupled to X-ray fluorescence spectrometer analysis to biomonitor the distribution of air pollutants in the city of Paranaguá. We identified a visual correlation between the level of the elements K and Cl, with high levels detected near fertilizer warehouses. A relation between Fe levels and position of railways and train stations were also clear. The low levels of the elements Zn, Al, Ba and Mg detected in a traffic restricted zone confirm the use of these elements as markers of vehicles traffic and validate the approach of using tree barks for air pollution biomonitoring.  ","PeriodicalId":11506,"journal":{"name":"Eclética Química Journal","volume":"43 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84544416","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
