1. Water pollution: one of the main Limnology challenges in the Anthropocene
Resumo: A humanidade está definindo um novo período geológico. A era do Antropoceno é marcada por mudanças nos processos geológicos, nos regimes hidrológicos, na estrutura da biosfera, dentre outros processos devido às expansões humanas sobre a paisagem ao redor do mundo. A aceleração dos ciclos biogeoquímicos, a grande carga de poluentes nos rec

3. Soil Chemistry after Irrigation with Treated Wastewater in Semiarid Climate
ABSTRACT Soil irrigation using treated wastewater in the Brazilian semiarid region is a promising practice as this area currently faces water scarcity and pollution of water resources by domestic sewage. The aim of this study was to evaluate the use of treated wastewater in drip irrigation and its effect on the chemistry of soil cultivated with squash (Cucur

4. Efeito indireto dos aerossóis: observações em nuvens amazônicas em atmosfera poluída e na transição para limpa segundo os dados dos programas LBA/SMOCC/ENFIM! E AERONET/NASA. / Indirect effect of aerosols: observations in the Amazon clouds in polluted air and clean transition to the second program data LBA / SMOCC / AT LAST! And AERONET / NASA.
In the Brazilian Amazon, fires occur seasonally. The pollution generated because changes in time weather and climate of the Amazon. Studies have shown that the emission of particulate matter alters the radiative balance via direct effect (Solar radiation scattering and reflection.) and indirect aerosol (Increased concentration droplet and the cloud content l

5. Desenvolvimento de um sistema para detecção de dispersóides no ar
The amount of dust suspended in air can be harmful to human health if not complied with the limits previously established by the WHO (World Health Organisation). The air is polluted when it contains elements foreign to its natural composition: oxygen, nitrogen, noble gases and water vapor and even carbon dioxide. The most common forms of air pollution are ca

6. Efeitos da aplicação de glifosato na química de solos alagados / Effects of glyphosate on the chemistry of flooded soils
This study aimed to evaluate the effects of the herbicide glyphosate in the chemistry of the flooded soils in two humid tropical areas included in the Brazilian savanna, observing these effects in the solid fraction and the soil solution. We used soil from an area of lowland irrigated rice cultivation and a preserved area of path, constituting, respectively,

7. Acúmulo tecidual de chumbo e seus efeitos sobre os processos osmorregulatórios de prochilodus lineatus
Os metais presentes no ambiente aquático podem interferir nos processos deosmorregulação dos teleósteos de água doce, além de se acumularem em diferentes tecidos dos peixes. Assim, o presente trabalho teve o objetivo de determinar o acúmulo tecidual de chumbo e seus efeitos sobre os processos osmorregulatórios de Prochilodus lineatus. Juvenis desta e

8. Dynamic adsorption of chromium ions onto natural and crosslinked chitosan membranes for wastewater treatment
Water pollution with heavy metals is a matter of major concern for public health and also for natural resource management. The present study investigated the effect of chemical modifications on biopolymeric adsorbents (based on chitosan membranes) for chromium removal using fixed-bed dynamic adsorption technique. Parameters such as flow rate, initial concent

9. Diverse uses of feathers with emphasis on diagnosis of avian viral infections and vaccine virus monitoring
The large amounts of feathers produced by the poultry industry, that is considered as a waste was explored for possible uses in various industries, such as meals for animals, biofuels, biodegradable plastic materials, combating water pollution and more. That review mentions these uses, but concentrate on the utilization of feathers for the diagnosis of viral

10. The effect of temperature on the reproduction of Limnodrilus hoffmeisteri (Oligochaeta: Tubificidae)
The tubificid worm Limnodrilus hoffmeisteri Claparede, 1862 is widely used as an indicator of organic pollution in aquatic environments. Nevertheless, little is known about its biology. The present work aimed to compare the reproductive rate of L. hoffmeisteri raised at three different temperatures (15, 20 and 25°C). Seventy-five adult individuals were kept

11. INTERMITTENT AND CONTINUOS FLOODING IN RICE: WATER USE, AGRONOMIC EFFICIENCY AND IMAZETHAPYR, IMAZAPIC AND FIPRONIL DISSIPATION / IRRIGAÇÃO CONTÍNUA E INTERMITENTE EM ARROZ IRRIGADO: USO DE ÁGUA, EFICIÊNCIA AGRONÔMICA E DISSIPAÇÃO DE IMAZETHAPYR, IMAZAPIC E FIPRONIL
Every anthropogenic activity causes environmental impact in some extent. Rice paddy fields area are pointed out as an activity with high potential of pollution due to the large amount of water used to maintain the flooding and the intensive use of pesticides and nutrients that can be transported to the environment. Though, there are other irrigation manageme

12. Efeitos citotoxicos e genotoxicos no meristema radicular de Allium cepa exposta a agua do Rio Paraiba do Sul - estado de São Paulo - regiões de Tremembe e Aparecida / Citotoxic and genotoxic effects in the root meristem of Allium cepa exposed to the water of the Paraiba do Sul river - São Paulo state - regions of Tremembe and Aparecida
One of the main sources of pollution of fresh water ecosystems refers to the discharge of industrial and urban wastes. Untreated sewage is considered an important cause to the deterioration of water quality in developing countries. Environmental pollutants have caused a decrease in water quality, inducing harmful effects in organisms which are in direct or i
