Uptake of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs) was studied in earthworms collected from a sawmill site in Sweden with severe PCDD/Fs contamination (the hot spot concentration was 690,000ng TEQWHO2005/kg d.w.) in order to investigate the transfer of PCDD/Fs from the site to the biota. PCDD/Fs concentrations in the collected earthworms were compared to PCD...

While many blood substitutes are based on mammalian hemoglobins (e.g., human hemoglobin, HbA), the naturally extracellular hemoglobins of invertebrates (a.k.a. erythrocruorins, Ecs) are intriguing alternative oxygen carriers. Specifically, the erythrocruorin of Lumbricus terrestris has been shown to effectively deliver oxygen in mice and rats without the negative side effects observed with HbA....

This study aimed to investigate the effects of tow nanoparticles (NPs) on the absorption, accumulation, reproduction of the Eisenia fetida. A 4×2×2 factorial experiment in a randomized complete block design with three replications was conducted. The factors included in the experiment are the content of NPs at four levels (0, 0.4, 0.8, and 1.2gr/kg weight of substrate), the type of NPs at two le...

The authors developed an environmentally safe technology for obtaining liquid organic fertilizer. includes compost by applying microflora containing actinomycetes and microscopic fungi, populating the with vermiculture Eisenia foetida biohumus. In 2018-2020 fertilizers obtained from waste were used on industrial plantings of technical variety Bastardo Magarachsky (planting scheme: 3 × 1.5 m, fo...

The objectives of this study were to provide data that can be used to predict exposure-based effects of RDX in aged soil on multiple endpoint organisms representing two trophic levels. These data can be used for defining criteria or reference values for environmental management and conducting specific risk assessment. Dose-response experiments formed the basis for the evaluation of toxic effect...

An information agent is viewed as a deductive database consisting of 3 parts: • an observation database containing the facts the agent has observed or sensed from its surrounding environment. • an input database containing the information the agent has obtained from other agents • an intensional database which is a set of rules for computing derived information from the information stored in th...

This work presents the dynamics of E. fetida (Sav.) earthworm populations during vermicomposting of duckweed (Lemna minor L.) biomass in small containers, and provides properties of the vermicomposts produced. An experiment was conducted under laboratory conditions (in darkness, at an average temperature 25±5oC, with substrate moisture 70-75%). Test pots (3 replications for each duckweed treatm...
