“…It is interesting to note that Zn was not only closely related to Pb but also to Cu, Cd, and As (Table 6). Zn discharge can be caused by a wide range of economic activities, including mining, smelting, coal burning, manufacturing, and the use of pesticides and fungicides [32][33][34], which frequently involve other trace elements.…”

An investigation was conducted to characterize the trace element status of mangrove soils of Qi’ao Island in the Pearl River estuary. The results show that the spatial variation in the soil-borne trace elements in the investigated area was minor and most of the trace elements were at a level higher than those in other mangrove wetlands around the world, suggesting the mangrove soils of Qi’ao Island were heavily contaminated by trace elements transported from the Pearl River in the past two decades. Zn was closely related to Pb, Cu, Cd, and As, while some trace elements were not closely related to each other, indicating that they were derived from different sources. An integrated Nemerow pollution index of the surface soils at the 17 sampling locations ranged from 7.53 to 48.42, values which all fall within the highest pollution category. Among the 17 sampling locations, six locations had an ecological risk index (ERI) greater than 300, and 12 locations had an Ecological Risk Index (ERI) greater than 600, indicating that most of the investigated locations were at high or very high ecological risk. The findings obtained from this study have implications for understanding the terrestrial inputs of trace elements into part of the Pearl River estuary. This understanding can be used to guide the development of management strategies for controlling the discharges of trace elements from the catchment area and managing the aquatic ecosystems in the Pearl River Estuary.

Lead poisonousness is a widely recognized type of heavy metal poisoning in humans and animals. So, this study aimed to assess the ameliorative role of cranberry extract use on hematological changes induced by lead acetate in rats. A total number of 40 adult male albino rats weighing approximately 200 ± 20 g were randomly assigned into four groups; Normal control group, group 2; Positive control, lead acetate at a dose of (50 PPM) for 45 days, group 3; Lead acetate at a dose of (50 PPM) then Cranberry extract (75 mg/kg) for 45 days also group 4; Lead acetate (50 PPM) then Cranberry extract (150 mg/kg) for 45 days. Blood samples were collected in EDTA tubes for hematological examinations. Oral administration of lead acetate (50 PPM) significantly decreased total erythrocyte count, hemoglobin, packed cell volume and mean cell volume levels in comparison with the normal control group (P< 0.0001). Addition of cranberry extract at a dose of 75 and 150 mg/kg significantly increased the total erythrocyte count, hemoglobin, packed cell volume and mean cell volume levels in comparison with the positive control group (P< 0.0001). Oral administration of lead acetate (50 PPM) significantly increased total leukocytes count, lymphocyte, neutrophils, eosinophil and monocytes counts in comparison with the normal control group (P< 0.0001). Addition of cranberry extract at a dose of 75 and 150 mg/kg significantly decreased the total leukocytes count, lymphocyte, neutrophils, eosinophil and monocytes counts in comparison with the positive control group (P< 0.0001). Our results clearly indicate that cranberry extract ameliorates hematological changes in lead acetatetreated rats.

“…Their natural sources comprise weathering of metal-bearing rocks and volcanic eruptions, whereas anthropogenic sources embody the development of mining operations, fertilizer industries, tanneries, sheet manufacture, pesticides, etc. Mining and industrial process for the extraction of natural resources and their resultant applications for industrial, agricultural and economic development have drawn a rise in the mobilization of those elements in the environment and disruption of their biogeochemical cycles [3,4]. Contamination of ecosystems with heavy metals will result in significant risks to public health.…”

Remediation of heavy metals (Cr, Zn) using physical, chemical and biological methods: a novel approach

et al. 2020

Heavy metal pollution has become one of the most significant environmental problems globally leading to ecological imbalance. There are many physicochemical and biological methods for the removal of heavy metals. Most of the physicochemical methods are less eco-friendly and less cost-effective, while the biological methods are slow in nature. Recently, nanoparticles have been suggested as efficient alternatives to existing treatment methods, in both resource conservation and environmental remediation of anthropogenic compounds. Nanotechnologies are pervasive solution vectors in our economic environment. Biological synthesis of nanoparticles has grown markedly to create novel materials that are ecofriendly, cost-effective and stable with great importance in wider application in the areas of electronics, medicine and agriculture. Thus, the current work focuses on a comparative remediation of heavy metals using physical, chemical and biological methods and nano-structured copper iodide is used as an adsorbent for the removal of chromium (Cr) and zinc (Zn). In the present study, we have experimented with a few methods in physical (UV light irradiation, adsorption studies using CuI), chemical (UV photocatalysis using CuI) and biological methods (using co-culture bacteria strains). A combination of chemical and biological methods was also probed using CuI-polyvinyl alcohol nano-composite containing bacterial co-cultures. The synthesized nano-composite was characterized using scanning electron microscope. The present study revealed that the most effective and cost-friendly method was using biologically prepared nano-composite of CuI (a combination of both chemical and biological methods) to remediate heavy metals Cr and Zn with a removal efficiency up to ~ 67% for Cr and ~ 55% for Zn at the end of 48 h.
