“…Another reason for their increased levels could be a result of the biotransformation of chromium in hepatocytes rendering injury to hepatocytes ( 41 ). Heavy metals are known to produce ROS in the body ( 42 ). Hepatocytes develop various defensive mechanisms to block ROS consequences.…”

The present study investigated the adverse effects of arsenic and chromium in broilers and ascertained the role of vitamin E and bentonite in alleviating their harmful effects. For this purpose, we experimented on 180 one-day-old broiler chickens. The feed was administered to broiler chicks of groups 2, 6, 7, 8, and 9 chromium @ (270 mg.kg−1 BW). Groups 3, 6, 7, 8, and 9 were administered arsenic @ (50 mg.kg−1 BW). Groups 4, 7, and 9 received vitamin E (150 mg.kg−1 BW), and groups 5, 8, and 9 received bentonite (5%), respectively. Group 1 was kept in control. All the broiler chicks treated with chromium and arsenic showed a significant (p < 0.05) decline in erythrocytic parameters on experimental days 21 and 42. Total proteins decreased significantly, while ALT, AST, urea, and creatinine increased significantly (p < 0.05). TAC and CAT decreased significantly (p < 0.05), while TOC and MDA concentrations increased significantly (p < 0.05) in chromium and arsenic-treated groups on experimental days 21 and 42. Pearson correlation analysis revealed a strong positive correlation between TAC and CAT (Pearson correlation value = 0.961; p < 0.001), similarly TOC and MDA positive correlation (Pearson correlation value = 0.920; p < 0.001). However, TAC and CAT showed a negative correlation between TOC and MDA. The intensity of gross and microscopic lesions was more in chromium (270 mg.kg−1) and arsenic (50 mg.kg−1) singly or in combination-treated groups. Thus, broiler chicks treated with chromium plus arsenic exhibited higher gross and microscopic lesion intensity than other treated groups. Fatty degeneration, severe cytoplasmic vacuolar degeneration, and expansion of sinusoidal spaces were the main lesions observed in the liver. Kidneys showed renal epithelial cells necrosis, glomerular shrinkage, and severe cytoplasmic vacuolar degeneration. Co-administration of bentonite along with chromium and arsenic resulted in partial amelioration (group 8) compared to groups 7 and 9, administered arsenic + chromium + vitamin E and arsenic + chromium + vitamin E + bentonite, respectively. It was concluded that arsenic and chromium cause damage not only to haemato-biochemical parameters but also lead to oxidation stress in broilers. Vitamin E and bentonite administration can ameliorate toxicity and oxidative stress produced by arsenic and chromium.

Growing industrialization and urbanization are seriously polluting the environment with hazardous heavy metals. Heavy metal pollution has caused major consequences on human health and the environment on a global level. Economically effective and environmentally friendly methodologies and technologies are utilized globally to remediate heavy metal-contaminated soils and wastewater. Phytoremediation is one of the potential technologies for the in-site treatment of heavy metal-contaminated soil and water. Over 163 plant species with the ability of metal concentration and tolerance have been discovered in the world as possible phytoremediators. Among the plant species used for phytoremediation, Cyprus rotundus is a safe and inexpensive phytoremediation agent that has a high capacity to accumulate heavy metals in its plant parts. This review provides a general overview of the phytoremediation potential of Cyperus rotundus through reviewing relevant originally published research articles. For the study, a literature survey was conducted by using articles from top academic research databases including ScienceDirect, JSTOR, Google Scholar, and PubMed. A total number of 71 originally published articles related to phytoremediation and heavy metal phytoremediation of Cyperus rotundus were selected for the review. According to previous studies, Cyperus rotundus is capable of extracting and accumulating As, Cd, Pb, Rb, Sn, and Zn in its roots and shoots when the soil is highly polluted with the aforementioned heavy metals. Moreover, Cypreus rotundus indicate a considerable value of bioconcentration factors and translocation factors to different heavy metals, whereas it emphasizes the possible remediation of heavy metals through this plant species. Consequently, Cyperus rotundus could be identified as a possible hyperaccumulator and Phytostabilizer for most heavy metals for upcoming phytoremediation studies.

“…Chromium is one of the important heavy metals that play an important role in enhancing the action of insulin and lowering the level of glucose in the human body [18], although its excess intake of chromium can lead to irregular heartbeats, headaches, allergic reactions, kidney and liver damage [19]. The excess amount of chromium in the soil/water also has adverse effects on plant growth and other important metabolic processes that make plants toxic such as oxidative stress [20].…”

This study was conducted to evaluate the six heavy metals zinc (Zn), iron (Fe), copper (Cu), nickel (Ni), chromium (Cr), and cadmium (Cd) in seven water samples collected from seven tribal districts (Bajaur, Mohmand, Khyber, Orakzai, Kurram, South Waziristan and North Waziristan) from Ex-FATA Pakistan. All samples were digested using the wet digestion method and the digested samples were analyzed for heavy metals using an atomic absorption spectrophotometer. Results from water samples from seven districts were compared to the recommended standard value from the World Health Organization and the Environmental Protection Agency. The results obtained from the analysis for nickel (Ni) showed that the highest concentration (0.093 mg/l) was reported in the water of Khyber district, while the lowest concentration (0.011 mg/l) was found in the water of South Orakzai district. Iron (Fe) had the highest concentration (0.32 mg/l) in the water of Orakzai district. The highest concentration (0.19 mg/L) of chromium (Cr) was reported in the water of Orakzai district. In addition, the result showed that the highest concentration (0.87 mg/l) of zinc (Zn) was in Orakzai district, the highest concentration (1.92 mg/l) of copper (Cu) in Khyber and Mohmand districts ( 1.92 mg/l), while the highest concentration (0.0029 mg/l) of cadmium (Cd) was measured in the water of Orakzai district. Therefore, based on comparison to WHO and EPA standard values, this study shows that the water of all tribal districts is safe for drinking water purposes
