The brine shrimp, Artemia spp., is widely used in ecotoxicological research as a biological index. In the present study, aquatic stability and acute toxic effects of TiO2, CuO and ZnO nanoparticles (NPs) on Artemia franciscana were investigated. Acute exposure was conducted in sea water with different concentrations of selected nanoparticles at 24h, 48h, 72h and 96h. The mortality rate of A. fr...

Acute exposure of A549 cells to Ag-NPs induces stronger effects on DNA integrity, ROS level, cell metabolism and cycle than repeated exposure. dissolves in both conditions Ag ions recombine with thiolated proteins.

 The major route of exposure is by inhalation.  Acute inhalation exposure to bromine vapour may cause upper respiratory effects, cough, headache, CNS effects and lacrimation.  Acute oral exposure to bromine results in central nervous system effects.  Deep partial skin loss and skin discolouration have been reported following acute dermal exposure to bromine.  Ocular exposure to bromine cau...

BACKGROUND A nationwide study was conducted to explore the short term association between daily individual meteorological parameters and the incidence of acute coronary syndrome (ACS) treated with coronary emergency catheter interventions in the Republic of Slovenia, a south-central European country. METHOD We linked meteorological data with daily ACS incidence for the entire population of Sl...

A low-cost yet highly sensitive colorimetric sensor array for the detection and identification of toxic industrial chemicals (TICs) has been developed. The sensor consists of a disposable array of cross-responsive nanoporous pigments whose colors are changed by diverse chemical interactions with analytes. Clear differentiation among 20 different TICs has been easily achieved at both their IDLH ...

The purpose of this study was to analyze the health risks benzene exposure, on human health, especially for workers/employees engaged in oil industry. To assess effects workers, it obtained from data workers exposed work environment. Acute exposure (14 days), moderate (15-364 days) and chronic (365 are workplaces where is below Minimum Risk Level (MRL) value inhaled that reduced by ATSDR acute,...
