The article provides information about a new device, AlgaTox developed in the R&D project sponsored by the Technology Agency (n.TA02030179) and patented in Czech Republic (CZ 305687). Its functionality is based on the use of biosensor, and its main advantage is fast response rate. The toxicity detection is achieved through precise measurement of green algae oxygen production dynamics after thei...

Abstract. Oxidative stress can be used to evaluate not only adverse health effects but also ecological effects, limited research uses eco-toxicological assay assess the risks posed by particle matters non-human biomes. One important reason might that concentration of toxic components atmospheric particles is far below high detection limit eco-toxic measurement. To solve rapid problem, we extend...

The growing increase in the world population, associated with increased demand for food, has promoted use of synthetic Plant Protection Products (PPPs as pesticides) agriculture, which can raise environmental concerns. Nowadays, it is generally believed that Biopesticides (BioPPPs) may contribute to reducing undesirable effects usually pesticides. However, risk assessment required by EU Member ...

Abstract The widespread use of the nanomaterials increases emission nano-pollutants into water. Carbon are particularly interesting. They characterized by relatively stable structure, which makes them able to migrate and accumulate in environment. Therefore, aim this study was determine potential toxicity at different trophic levels four selected carbon nanostructures: graphene oxide (GO), redu...

The pace of technological advancement in today’s society has generated an enormous demand for methods facilitating the intelligent testing for the toxicity of new chemicals. Until now it is common use to make prediction based on ‘real’ tests. Recent investigations support the general assumption that macroscopic properties like toxicity and ecotoxicity strongly depend on microscopic features and...

Lead acetate (AcPb) is an important raw material used in chemical industries worldwide. The potential toxicity of AcPb generally attributed to the presence Pb. However, effect on environment as a whole still poorly known. This study aimed evaluate three standard species soil invertebrates and two plant using ecotoxicology tests. Three tropical soils (Oxisol, Inceptisol, Tropical Artificial Soil...
