“…Morphometric parameters and biological features are widely used by forensic entomologists to establish the minimum time elapsed since death (Bharti, 2009;Chen et al, 2011). Thus the information presented in our article is very useful for experts in forensic entomology for the time corpses' decay evaluation (Greenberg, 1991;Zhang and Pu, 2011), especially in industrialized regions of planet, where lead and cadmium are major technogenic pollutants (Bobyliov et al, 2014).…”

“…As a result of the increasing level of usage of these metals in industry, they negatively affect human health (Ahamed and Siddiqui, 2007;Zhang and Pu, 2011;Li et al, 2011). When intruding into the biogeochemical processes in natural ecosystems, heavy metal compounds disrupt the stability of elementary compounds of biological systems at different levels of their organization.…”

Shulman, M.V., Pakhomov, O.Y., Brygadyrenko, V.V., 2017. Effect of lead and cadmium ions upon the pupariation and morphological changes in Calliphora vicina (Diptera, Calliphoridae). Folia Oecologica, 44: 28-37.Modelling the influence of different concentrations of lead and cadmium ions upon a laboratory culture of insects has not been adequately studied. In our research, we assessed the influence of cadmium and lead nitrates at different concentrations (10 -2 -10 -9 М) upon the development of larvae, pupae and imagines of Calliphora vicina Robineau-Desvoidy, 1830 (Diptera: Calliphoridae). We found an acceleration in the development of larvae and an increase in mass of puparia when lead ions were added to the food of the larvae, and decrease in the mass of puparia when cadmium ions were added. We registered nanism and malformation of the fly imagines in experiments with lead and cadmium in the food substrate. We observed that under the influence of the studied heavy metal ions there was a reduced motor activity of the fly larvae at all stages of development, a delay in formation of puparia and a delay in the emergence of imagines in comparison with the control group.

“…Thawornchaisit and Polprasert [22] showed that the nature of phosphate phase in triple superphosphate, diammonium phosphate, and phosphate rock, contributes to stabilize cadmium in contaminated soils. Similarly, Zhang and Pu [23] evidenced a change in the availability of cadmium, copper, lead, and zinc, following applications of rock phosphate, calcium magnesium phosphate, limestone, and palygorskite. In the context of the remediation of contaminated soils, many authors have also demonstrated that the stabilization of potentially toxic metals such as Pb, Cu, or Zn, depends on the nature of phosphate rock used [24][25][26].…”

Phosphate fertilizers represent a major source of trace metal contaminants in agricultural soils. To predict the inputs and the fate of trace metals in soils of the eastern Mediterranean region, a speciation study was conducted using a total of 44 phosphate fertilizers commercialized in the area. The contents in major anions and potentially toxic metals (Zn, Pb, Cd, and Cu) were determined using atomic absorption spectrometry (AAS) and X‐ray fluorescence spectrometry (XRF). The nature of mineral phases in the fertilizer was characterized using X‐ray diffraction and Fourier transform infrared spectrometry. The results show that sulfates are the main Cd‐bearing phases when present in the P‐fertilizer. The contents in Zn and Pb were linearly related, whereas the levels of Sb, Ag, Pd, Nb, Mo, and P2O5 were strongly correlated to each other. The annual average inputs of Zn, Cu, Pb, and Cd were calculated to be 922, 124, 26, and 6 g/ha per year, respectively. Even though such inputs comply with the maximal metals concentrations authorized in temperate countries, an accumulation of those metals in the typical arid and alkaline soils of the eastern Mediterranean countries is expected.

“…Montmorillonite had better potential to reduce copper than attapulgite. Zhang and Pu 12 reported the ability to retain heavy metals in four soil amendments, namely agricultural limestone, rock phosphate, palygorskite, and calcium magnesium phosphate. Additives were mixed at a ratio of 2% and 5% into the calcareous soil and acidic soil contaminated with lead, cadmium, copper, and zinc.…”

The aim of this research was to reduce the heavy metal movement to the biosystem using clay minerals including zeolite, sepiolite, and diatomite. The clay soil and sandy loam soil were made contaminated with 200, 350, 700, and 250 mg of Zn, Cu, Cr, and Ni per kg of soil, respectively. The ratio of clay minerals added to soils was 2.5%, 5%, and 7.5%. The determination of various forms of heavy metals bound to soil mixed with clay minerals and left for a period of 30 and 60 days was carried out using the sequential extraction method. The results indicated that Ni and Zn were mostly in an exchangeable form, while Cu and Cr were mostly in an oxide bound form and an organically bound form. The pH of the soils increased after adding clay minerals. Diatomite caused the smallest change in the pH value. Chromium had the best adsorption capacity by bonding with various elements in the soil, followed by Cu, Zn, and Ni, respectively. The addition of sepiolite caused more heavy metals in a stable form than adding zeolite and diatomite. When adding clay minerals to both types of soil, the highest impact was on Ni, followed by Zn, Cu, and Cr, respectively. The bioavailable index (BI) value was the least when adding sepiolite. The risk of heavy metals moving to the biosystem was lower when increasing the incubation time. Without adding any clay mineral, the BI value of metals in the sandy clay loam soil was higher than that in the clay soil.
