Bioaccumulation of cadmium in common green bottle fly Lucilia sericata and its impact on insect development - prospect for use in feed and food production.

This study aimed to investigate the bioaccumulation of cadmium from natural feed substrate and substrate enriched with CdCl and CdO by the common green bottle fly, Lucilia sericata (Diptera: Calliphoridae). Cadmium was determined in all developmental stages (larvae, adults, and puparial cases) of L. sericata, and its accumulation was positively correlated with concentrations in insect diets.

Photosynthesis governed by nanoparticulate titanium dioxide. The Pisum sativum L. case study.

Wide availability of anthropogenic TiO nanoparticles facilitates their penetration into environment and prompts interactions with plants. They alter plants growth and change their nutritional status. In particular, metabolic processes are affected.

Ecotoxicological assessment of magnetite and magnetite/Ag nanoparticles on terrestrial and aquatic biota from different trophic levels.

The aim of the study is an ecotoxicological assessment of magnetite iron oxide-based nanoparticles (NPs), which have risen in popularity in the last decade, on selected terrestrial and aquatic organisms from various levels of the food chain. In the presented study various organisms, from both the terrestrial and aquatic environment, were used as targets for the assessment of NPs ecotoxicity. Plants (radish, oat), marine bacteria (A.

Uptake, translocation, weathering and speciation of gold nanoparticles in potato, radish, carrot and lettuce crops.

Extensive use of nanomaterials in agriculture will inevitably lead to their release to the environment in significant loads. Thus, understanding the fate of nanoparticles in the soil-plant environment, and potential presence and consequent implication of nanoparticles in food and feed products, is required. We study plant uptake of gold nanoparticles from soil, and their distribution, translocation and speciation (in terms of particle size change and release of ionic Au) in the different plant tissues of four important crops (potato, radish, carrot and lettuce).

Puparial Cases as Toxicological Indicators: Bioaccumulation of Cadmium and Thallium in the Forensically Important Blowfly .

In this study, we present entomotoxicological data on the accumulation of cadmium and thallium in a forensically important blowfly, , and evaluate the reliability and utility of such information as toxicological evidence for poisoning as a cause of death. We observed that Cd and Tl content in different growing stages of (larvae, puparial cases, and adults) was increasing with increasing metal concentration in the feeding substrate, namely metal-enriched liver. However, patterns of accumulation differed between the two metals investigated, showing a linear relationship for Cd and a saturable pattern for Tl.
