Evaluation of the Effects of Wastewater Irrigation on Heavy Metal Accumulation in Vegetables and Human Health in the Cauliflower Example : Heavy Metal Accumulation in Cauliflower
Bull Environ Contam Toxicol. 2024 Feb 28;112(3):44. doi: 10.1007/s00128-024-03858-1.ABSTRACTThe goals of the present research were to determine the heavy metal contents in the water-soil-cauliflower samples in industrial wastewater irrigated areas and to assess the health risks of these metals to the people. Metal analyses were carried out using the atomic absorption spectrophotometer equipped with a graphite furnace. The metal readings in the cauliflower specimens ranged from 1.153 to 1.389, 0.037 to 0.095, 0.61 to 0.892, 0.625 to 0.921, 1.165 to 2.399, 0.561 to 0.652, 0.565 to 0.585, 0.159 to 0.218 and 1.268 to 1.816 mg/...

Seasonal Monitoring of Heavy Metal Pollution in Water and Zebra Mussels Dreissena polymorpha as a Potential Bioindicator Species from Lake Habitat
Bull Environ Contam Toxicol. 2024 Feb 26;112(3):43. doi: 10.1007/s00128-024-03869-y.ABSTRACTIn aquatic ecosystem, metal pollution is an important environmental hazard. Mussels as a bioindicator species are often used for assessment the presence of potentially toxic metals. Hence, the present study aimed to assess the effect of seasonal variations on some heavy metals (Cd, Cr, Pb, As, Zn and Cu) accumulation in water and Dreissena polymorpha from lake habitat. Our result indicated that Zn accumulated at a very high level in the zebra mussels while As accumulated at a high level in water samples. Seasonal variations signific...

Long-term Exposure to Industrial Chemical Contamination Affects the Magnitude of Predator-induced Immunosuppression in a Free-living Passerine
Bull Environ Contam Toxicol. 2024 Feb 25;112(3):42. doi: 10.1007/s00128-024-03857-2.ABSTRACTIndustrial chemical contamination is known to have immuno-toxic effects on birds. It may also interfere with natural stressful conditions to further disrupt the immune responses, but these possible interactive effects are still poorly documented in free-living birds. Using the phytohaemagglutinin skin-swelling test, we assessed how the T-cell mediated immune response varied according to the perceived risk of predation in hybrid sparrows, Passer domesticus × Passer hispaniolensis, originating from two sites differentially impacted b...

Degradation of Plastic Beads Containing Low Density Polyethylene (LDPE) by Sequential Photolysis, Hydrolysis and Bacterial Isolates
In this study, an attempt was made to explain the degradation of low-density polyethylene (LDPE) plastic beads with the help of selected bacterial isolates in both laboratory and field conditions. 16 S rRNA gene sequencing further identified the bacterial isolates as Micrococcus luteus and Bacillus pumilus, obtained from the municipal waste disposal site near Anand, Gujarat, India. The beads were subjected to photolysis and hydrolysis for a predetermined amount of time in addition to biodegradation. After 60 days of treatment with Pseudomonas aeruginosa, Micrococcus luteus, and Bacillus pumilus in both laboratory and field...

Study of the Toxicity and Translocation of Chromium (VI) in Vicia faba Plant
Bull Environ Contam Toxicol. 2024 Feb 21;112(3):40. doi: 10.1007/s00128-024-03864-3.ABSTRACTIn soil, chromium can be found in two main valence forms: hexavalent Cr (VI) and trivalent Cr (III). In terms of toxicity, the most toxic form to plants is Cr (VI). In the present study, we investigated the impact of Cr (VI) (0, 25, 50, 75 and 100 ppm) on growth, physiological parameters and the translocation kinetics of Cr (VI) in the faba bean plant (Vicia faba L.). The results showed that Cr (VI) negatively affects growth parameters (- 15% to - 72%), tolerance index (- 34.05% to - 64.7%), and reduce the total chlorophyll content ...

A Latest Review on Micro- and Nanoplastics in the Aquatic Environment: The Comparative Impact of Size on Environmental Behavior and Toxic Effect
Bull Environ Contam Toxicol. 2024 Feb 14;112(2):36. doi: 10.1007/s00128-024-03865-2.ABSTRACTMicro and nanoplastics (MNPs) have attracted growing global research attention due to their distinct environmental impacts, addressing escalating concerns. The diverse materials, sizes, and shapes of MNPs result in a range of environmental impacts. Size, a crucial characteristic of MNPs, influences their environmental behavior, affecting processes like migration, sedimentation, aggregation, and adsorption. Moreover, size modulates the biodistribution and toxicity of MNPs in aquatic organisms. This review delves into the comprehensiv...

Biochemical Response of the Endogeic Earthworm (Balanteodrilus extremus) Exposed to Tropical Soils
Bull Environ Contam Toxicol. 2024 Feb 14;112(2):35. doi: 10.1007/s00128-024-03860-7.ABSTRACTThis work evaluated the biochemical responses of the endogeic earthworm Balanteodrilus extremus exposed for 14 and 48 days (d) to soils collected from two tropical agricultural systems: maize-sorghum (MS) and soybean-sorghum (SS). A soil without agricultural management (WAM) and the use of pesticides was selected as a reference. The presence of organochlorine (OC) and organophosphate (OP) pesticide residues was quantified in MS and SS soils. Biomarkers of detoxification [glutathione S transferase (GST)], neurotoxicity [acetylcholine...

Inhibitory Effect of Acetaminophen on Ocular Pigmentation and its Relationship with Thyroxine in Zebrafish Embryos
Bull Environ Contam Toxicol. 2024 Feb 14;112(2):39. doi: 10.1007/s00128-024-03867-0.ABSTRACTAcetaminophen (N-acetyl-p-aminophenol; APAP) is one of the most widely used analgesics. To examine the toxicity of APAP, we used zebrafish embryos as model animals to detect the effect of APAP on the thyroid system of zebrafish embryos. The zebrafish embryos were exposed to APAP from 4 h post fertilization (4 hpf) until observation. The experimental results showed that APAP caused pericardial edema and decreased pigmentation in the zebrafish embryos or larvae. The APAP treatment caused a decrease in the expression of tpo and thrβ i...
