“…To each triplicate sample, 20 cm 3 of 0.5 moldm -3 trioxonitrate (V) acid was added and filtered into 50 cm 3 volumetric flask through Whatman No 42 filter paper. The filtrate obtained was made up to 50 cm 3 mark with distilled water and stored in pre-cleaned polyethylene bottles for heavy metals analysis using Atomic Absorption Spectrometer (Buck Scientific model 210 VGP) [19,20].…”

Freshwater is a vital medium by which fish for human consumption are cultured, thus, preserving its quality is essential. The presence and bioaccumulation pattern of some heavy metal concentrations in wild African Catfish, Clarias gariepinus (Burchell, 1822) muscles and water samples, collected from River Kaduna during the dry season month of December was assessed, to determine their concentrations, physico-chemical parameters, and risk evaluation of selected metals and their effects on fish quality. Analysis was carried out using standard analytical procedures and methods. Risk assessment for Fe, Pb, Ni, Cd, and Hg were based on average daily dose, hazard quotient, and cancer risk was also determined. Result showed that physico-chemical parameters, were within WHO recommended threshold limits, and mean concentrations of heavy metals followed the order Fe>Pb>Hg>Ni>Cd. Carcinogenic risk () via ingestion of fish muscles for Pb, Hg and Cd were higher than the acceptable limit (10-6). Anthropogenic activities, especially indiscriminate waste disposal were suggested as the main contributor to environmental pollution. Findings reveals possible health implications, thus constant surveillance was suggested to guide appropriate response.

“…These experiments revealed that the higher the dosage of natural zeolite has an implication for reducing reduce heavy metal remained in soil samples. Compared to soil quality standard, the addition 5% dosage of natural zeolite was sufficient to reduce the concentration of Pb, Cu and Zn from 500 mg/kg to the acceptable level of soil quality standard published by Dutch Environmental Agency [13]. However, on Cd concentration, after 20% of natural zeolite was added to a sample, it shows that sufficient to meet the soil quality standard.…”

An experiment of the immobilization of heavy metals Pb, Cu, Zn, and Cd in contaminated soil by using the natural zeolite was performed in the laboratory. The natural zeolite was obtained from Gunungkidul, Yogyakarta, Indonesia. Artificially contaminated levels on 100, 300 and 500 mg/kg were prepared and then mixed with three different dosages of 5%, 10% and 20% of the natural zeolite. The result revealed that the addition of natural zeolite effect on reducing the heavy metal in the contaminated soil. The addition 5% dosage of the natural zeolite was sufficient to reduce the concentration of Pb, Cu and Zn from 500 mg/kg to the maximum permissible of concentration level. Finally, the natural zeolite immobilized the heavy metals in the contaminated soil by following in order: Pb2+>Cu2+>Zn2+>Cd2+.

“…The PLI values ranged from 0.94 to 1.65. According to the PLI value (Lactusu, 2000), three sampling points (Sp10, Sp14, and Sp18) were found to be very severely contaminated (0.76–1.00), whereas 21 sampling points (Sp1‐Sp9, Sp11‐Sp13, Sp15‐Sp17, and Sp19‐Sp24) were moderately polluted (1.10–2.00) depicted in Exhibit 4b. PLI value below 1.00 have no negative consequences on soil, plants, and surrounding.…”

This study investigated the concentrations of arsenic (As) in soil and plant biomass from the Barak Valley in South Assam, India. Soil samples showed concentrations ranging from 6.06 ± 0.84 mg/kg to 18.61 ± 1.52 mg/kg, with an average of 10.60 ± 3.15 mg/kg, 41.67% of the sample exceeding uncontaminated ranges (0.1–10 mg/kg). Ecological risk assessments such as contamination factors, pollutant load index, geo‐accumulation index, and anthropogenicity identified varying contamination levels across sampling points. A total of 24 plant species were collected, ferns (two species), shrubs (five species), grass (six species), and herb (11 species). The concentration of As in different plants types decreased in the order of fern (393.45 ± 159.63 mg/kg) > shrub (20.48 ± 7.25 mg/kg) > herb (17.92 ± 13.75 mg/kg) > grass (14.98 ± 13.80 mg/kg). Plant species, namely Pityrogramma calomelanos, Christella dentata, Mimosa pudica, Chromolaena odorata, Leucas aspera, Persicaria decipiens, Melastoma malabathricum, and Clerodendrum infortunatum, accumulated higher concentrations of As in their above‐ground parts compared to roots and were categorized as tolerant accumulators (TF > 1). By incorporating these plant species into phytoextraction strategies, the region can benefit from their unique properties and abilities to effectively remediate arsenic‐contaminated sites, ultimately improving the affected areas' environmental and human health conditions.
