3. Stability Analyses by HPLC-MS of Guanitoxin Isolated from Sphaerospermopsis torques-reginae
Guanitoxin (GNT) is a natural organophosphate produced by some species of freshwater cyanobacteria, which inhibits the active site of acetylcholinesterase, preventing the hydrolysis of cholinesterases and consequently causing serious disturbances in the neuromuscular system. Despite having a chemical structure like synthetic organophosphates, there is still

4. Avaliação da concentração e composição inorgânica do material particulado coletado no estado do Rio de Janeiro
Cities urbanization and modernization increase emission sources, contributing to particulate matter (PM) composition heterogeneity and enhance the risk to human health and environment. This paper intends to survey the studies on particulate matter carried out in the state of Rio de Janeiro. The sampling of PM is generally made using Hi-Vol samplers to collec

6. A SIMPLE AND SENSITIVE LC-MS/MS METHOD FOR THE DETERMINATION OF S-PHENYLMERCAPTURIC ACID IN HUMAN URINE
Benzene is an important environmental and occupational pollutant, and recognized as human carcinogen. S-phenylmercapturic acid (SPMA) is a highly specific biomarker of exposure to benzene, applied in occupational toxicology to assess low levels of benzene exposure. The objective of this study was to develop and validate a one-step liquid extraction bioanalyt

8. ACHPA: A sensor based system for automatic environmental control in hydroponics
Abstract The trend towards tunnel farming and hydroponic systems is increasing owing to the climatic changes as well as the need to increase crop yield. Hydroponic is a technique of growing plants without soil. Tunnel farming and hydroponic system requires controlled environmental parameters like temperature, humidity and soil moisture for better production

9. Evaluation of environmental rehabilitation practices in bauxite mining at the plateau of Poços de Caldas
Abstract Bauxite mining has been carried out around Poços de Caldas, Minas Gerais, since the 1940s. Companies operating in the region pioneered land rehabilitation in Brazil, conducted since the early 1980s. Different procedures of recontouring, runoff drainage, soil preparation and vegetation planting were employed. This research aims to evaluate current e

11. Relationship between phytoplankton structure and environmental variables in tropical reservoirs with different trophic states
ABSTRACT Phytoplankton structure is influenced by environmental factors, seasonal cycles and the trophic state of the system. The objective of the present study was to identify guilds of phytoplankton species that are representative of seasonality and trophic status. We evaluated phytoplankton biomass and species composition in five tropical reservoirs, with

12. Estimation of mercury released from an abandoned gold mine in Minas Gerais, Brazil
Abstract Mining is very important to the economic, political and social development of the Minas Gerais State in Brazil ever since the time the country became a Portuguese colony in the early 1500s. However, few researches have been conducted to evaluate the environmental impacts associated with the mining activity at this time. There are many abandoned mine
