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...

The aim of this study is to assess the environmental impacts household life cycles in Santiago, Chile, by income level. assessment considered scenarios associated with policies. cycle was cradle-to-grave, and functional unit all materials energy required meet an inhabitant’s needs for one year (1 inh/year). Using SimaPro 9.1 software, Recipe Midpoint (H) methodology used. impact categories sele...

In this paper we utilise a stochastic address model of broadcast oligopoly markets to analyse the Australian broadcast television market. In particular, we examine the effect of the presence of a single government market participant in this market. An examination of the dynamics of the simulations demonstrates that the presence of a government market participant can simultaneously generate posi...

There is growing concern that recreational shoreline angling activity may negatively impact littoral and riparian habitats independent of any direct or indirect influences of fish harvest or fishing mortality through mechanisms such as disturbance (e.g., trampling, erosion) and pollution (e.g., littering). We sampled a suite of aquatic and terrestrial variables (i.e., water quality, aquatic and...

The fact that the results for 2-receiver broadcast channels (BCs) are not generalized to the 3-receiver ones is of information theoretical importance. In this paper we study two classes of discrete memoryless BCs with non-causal side information (SI), i.e. multilevel BC (MBC) and 3-receiver less noisy BC. First, we obtain an achievable rate region and a capacity outer bound for the MBC. Second,...

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...
