Ecotoxicological evaluation of wastewater from 2.4.6-TNT production
During the manufacture of explosives, large amounts of water are used to remove unwanted by-products generated. This water in turn, ends up in wastewater treatment plants or water bodies. The aim ofExpand

Responses of Aquatic Nontarget Organisms in Experiments Simulating a Scenario of Contamination by Imidacloprid in a Freshwater Environment
Several studies have indicated the presence of the neonicotinoid insecticide imidacloprid (IMI) in aquatic ecosystems in concentrations up to 320.0 µg L−1. In the present study, we evaluated theExpand
Thermal dehydration of lanthanum chloride heptahydrate: thermodynamic approach
Abstract Production of rare-earth metals from molten chloride electrolysis demands the use of anhydrous chloride in order to increase current efficiency. The main difficulty in obtaining theseExpand
Hydrogen sulphide scavenging by porous magnetite
Abstract Hydrogen sulphide known for its smell of 'rotten eggs' is a very toxic and corrosive gas. Small concentrations in drilling mud as low as 10 ppm, can reduce significantly drill pipe life byExpand
Tantalum electrowinning from molten fluorides: characterization of structure and defects
high melting-point and corrosion resistance—in which it is matched only by glass, graphite and PTFE1,2,3—other applications, such as in superalloys for the aircraft industry and in the chemicalExpand
Distribution and density of mixed‐input ON bipolar cells of the goldfish (Carassius auratus) during growth
Neurons are continuously produced at different rates and locations in the teleost retina. Goldfish rods are homogeneously distributed and maintain a stable density throughout growth, whereas littleExpand
Treatment of wastewater from a cotton dyeing process with UV/H2O2 using a photoreactor covered with reflective material.
Wastewater containing several dyes, including sulfur black from the dyeing process in a textile mill, was treated using a UV/H2O2 process. The wastewater was characterized by a low BOD/COD ratio,Expand
