“…Biochemical analysis is progressively used in ecotoxicological studies to monitor the ubiquity of xenobiotics [ 17 ]. Biochemical alterations have been attributed to the negative effects resulting from vulnerability to a contaminant [ 18 ]. A molecular biomarker is a significant tool for the evaluation of ecotoxicity in living organisms.…”

The present research aims to evaluate the impact of industrial processes and anthropogenic activities on the beetle Pimelia latreillei inhabiting the polluted site at Zawya Abd El- Qader, Alexandria, Egypt. Beetles were collected from the vicinity of five factories. The genotoxic effects of environmental exposures to industrial heavy metals were monitored using a broad range of assays, including energy-dispersive X ray microanalysis and X-ray diffraction (SEM and EDX)), qRT-PCR gene expression assay, micronuclei formation, and transmission electron microscope (TEM). Energy dispersive X-ray microanalysis for the soil and testicular tissues of beetles collected from the polluted site revealed a higher percentage of heavy metals than the beetles collected from the reference site (Sidi Kirier, Alexandria, Egypt). To analyze/monitor genotoxicity in P. latreillei sampled from the polluted site, the transcription levels of levels of heat shock proteins (Hsps) and accessory gland seminal fluid protein (AcPC01) in testicular tissues were recorded. The incidence of micronuclei (MN) formation in the testicular cells was also observed. Quantitative RT-PCR (RT-qPCR) analysis was carried out to detect the changes in the gene expression of the aforementioned proteins. Genes encoding heat shock proteins (Hsp60, Hsp70, and Hsp90) were significantly overexpressed (> 2-fold) in specimens sampled from the polluted site; however, AcPC01 gene expression was under-expressed (<1.5-folds). The incidence of MN was significantly increased in specimens sampled from the polluted site. Ultrastructure anomalies (nuclear and cytoplasmic disruption) were also observed in the testicular cells of the beetles sampled from the polluted site compared to those sampled from the unpolluted site. Our results, therefore, advocate a need for adequate measures to reduce increasing environmental pollution in the urban-industrial areas.

“…z nadmierną akumulacją szkodliwych substancji, takich jak metale ciężkie czy węglowodory (głównie ropopochodne), w ekosystemach wodnych i glebowych [6]. Do zanieczyszczania środowiska omawianymi składnikami dochodzi zarówno w wyniku naturalnie zachodzących w przyrodzie procesów, jak i na skutek uwalniania ich do środowiska w ramach różnych działań antropogenicznych, takich jak: górnic-two, działalność przemysłowa, galwanizacja, obróbka osadów ściekowych, rolnictwo, motoryzacja [1,3,4,7,8,9,11]. Duże, przekraczające dopuszczalne normy, nagromadzenie się zarówno węglowodorów, jak i metali ciężkich w glebie negatywnie wpływa na wegetację roślin oraz pozostałe organizmy obecne w takim ekosystemie.…”

Ocena zmian toksyczności gleby skażonej niklem i substancjami ropopochodnymi w procesach fitoremediacji W artykule omówiono zagadnienia związane z oczyszczaniem gleb skażonych niklem i substancjami ropopochodnymi. Do oczyszczania skażonej gleby wytypowano technologię opartą na fitoremediacji wykorzystującej aktywność roślin z grupy hiperakumulatorów i naftofitów (Lettuce iceberg, Melilotus officinalis, Festuca arundinacea) do pobierania zanieczyszczeń przez system korzeniowy. Na podstawie badań laboratoryjnych określono zarów-no wpływ rodzaju fitoremedianta na proces oczyszczania gleby, jak i oddziaływanie obecności substancji ropopochodnych na proces oczyszczania gleby zanieczyszczonej niklem. Podjęcie się realizacji tego zadania wymagało wykorzystania metod badawczych obejmujących analizy fizykochemiczne i badania toksykologiczne gleb, do przeprowadzenia których zastosowano mikrobiotesty typu ToxKit. Po zakończeniu 6-miesięcznego procesu fitoremediacji wykonano analizę chemiczną materiału roślinnego, celem określenia zawartości niklu w części naziemnej i korzeniu wytypowanych do badań fitoremediantów. Na podstawie uzyskanych wyników sformułowa-no wnioski dotyczące zagadnień związanych z zastosowaniem fitoremediacji w procesie oczyszczania skażonych gleb w zależności od stężenia i rodzaju substancji toksycznej. Ponadto określono, jakie rośliny spośród badanych są najlepiej przystosowane do wzrostu na skażonym terenie oraz jaki wymierny skutek obniżenia zanieczyszczeń przy ich wzroście można osiągnąć.Słowa kluczowe: fitoremediacja, gleba skażona, nikiel, substancje ropopochodne, testy toksykologiczne. Evaluation of toxicity changes in soil contaminated with nickel and petroleum-derived substances in phytoremediation processesThe article discusses issues related to cleaning of soils contaminated with nickel and petroleum-derived substances. Technology based on phytoremediation process that exploits activity of plants from the hyperaccumulator and petroleum-resistant plants group (Lettuce iceberg, Melilotus officinalis, Festuca arundinacea) was selected to clean the soil. Based on laboratory tests the impact of both the type of phytoremediation on the process of cleaning the soil, as well as the impact of the presence of oil on the process of cleaning soil contaminated with nickel was determined.This task requires the use of research methods such as physiochemical analysis and soil toxicological studies that utilize ToxKit microbiotests. Biomass chemical analysis in order to determine the nickel content in the aerial parts and roots was performed at the end of a 6-month process. Based on the obtained results conclusions related to the application of phytoremediation in soil remediation cleaning process depending on the concentration of toxic substance were edited. The types of plants that best adapt to growing in the contaminated area and reduction in the level of contamination due to their growth was also described in the article.

Abstract-Heavy metals, such as lead, have caused deleterious effect not only to the environment, but also to the public's health. In the Philippines, the ornamental plant Bougainvillea has been planted on the main roads of cities due to its capacity to thrive in heavily polluted areas. Studies show that Bougainvillea may be utilized to reduce heavy metal pollution through absorption and adsorption in soil and air, respectively. In this study, the plant's leaves were used to measure the lead accumulated, adsorbed and absorbed from two cities in Metro Manila, specifically Las Piñas and Manila. The lead concentration of the plant and its soil was measured through Flameless Atomic Absorption Spectrophotometer (AA-6300, Shimadzu, France), and the duration of measurement lasted for nine months with four time periods (0, 3, 6 and 9 th month-interval). Two-way t-test and ANOVA were used to analyze the data gathered. It was found that there is no sufficient evidence to conclude that lead content of the plants in Manila differs significantly from that of Las Piñas. Moreover, results show that Bougainvillea lead uptake may vary depending on various environmental factors, such as concentration of lead in soil, climatic condition, degree of heavy metal pollution and complexes of lead form in other soil components.Index Terms-Bougainvillea, flameless atomic absorption spectroscopy, heavy metals, lead absorption ability.
