“…The non-carcinogenic health risk (NCHR) posed by the consumption of the various parts of tilapia contaminated with HMs was defined by THQ and was estimated by following Equation (2) [ 28 , 38 ].

where R f D is the reference dose of metals that provides an estimate of the daily exposure of an individual to a particular contaminant such as HM with a potential non-carcinogenic health risk [ 39 ] The R f Ds for As, Ba, Cd, Cu, Fe, Pb, Mn, Hg, Ni, and Zn are 0.0003, 0.2, 0.001, 0.04, 0.7, 0.0035, 0.14, 0.0001, 0.02, and 0.3 mg kg −1 , respectively [ 40 , 41 , 42 , 43 , 44 , 45 , 46 ]. Generally, a THQ < 1 implies very little to no non-carcinogenic health effects.…”

Concentrations of heavy metals (HMs) were assessed in Tilapia spp. from selected communities in Calapan City, Philippines. Eleven (11) inland farmed tilapia samples were collected and analyzed for HMs concentration using X-ray fluorescence (XRF). The 11 fish samples were cut into seven pieces, according to the fish body parts, constituting a total of 77 samples. These fish samples were then labeled as bone, fins, head, meat, skin, and viscera. Results showed that the mean concentration of Cd in all parts of tilapia exceeded the Food and Agriculture Organization/World Health Organization (FAO/WHO) limits. The highest concentration was recorded in the fins, which was sevenfold higher than the limit. The trend of the mean concentration of Cd in different parts of tilapia was fins > viscera > skin > tail > head > meat > bone. The target hazard quotient (THQ) recorded a value less than 1. This means that the population exposed to tilapia, within the area where fish samples originated, were not at risk to non-carcinogens. The concentrations of Cu, Pb, Mn, Hg, and Zn in different parts, particularly in skin, fins, and viscera, also exceeded the FAO/WHO limits. The calculated cancer risk (CR) in consuming the fish skin, meat, fins, bone, viscera, and head was higher than the USEPA limit. This indicated a possible carcinogenic risk when consumed regularly. Most of the correlations observed between HMs in various parts of the tilapia had positive (direct) relationships, which were attributed to the HM toxicity target organ characteristics. Results of the principal component analysis (PCA) showed that most of the dominating HMs recorded in tilapia were attributable to anthropogenic activities and natural weathering within the watershed of agricultural areas. The agriculture area comprises about 86.83% of the overall land area of Calapan City. The identified carcinogenic risks were associated with Cd. Therefore, regular monitoring of HMs in inland fishes, their habitat, and surface water quality shall be carried out. This information is useful in creating strategies in metals concentration monitoring, health risks reduction program, and relevant guidelines that would reduce the accumulation of HM in fish.

“…Some heavy metals with stronger toxicity such as Cd, As and Pb, are well studied because of their persistence, toxicity and nonactive degradation. Others heavy metals are essential elements for plant growth [ 13 ], such as Fe, Cu, Zn, but too much of these will cause heavy metal pollution. Cd is one of the most hazardous elements and has been a public concern with increasing risk in soil remediation.…”

Background Cadmium (Cd) contamination in soil poses a serious safety risk for the development of medicine and food with ginseng as the raw material. Microorganisms are key players in the functioning and service of soil ecosystems, but the effects of Cd-contaminated ginseng growth on these microorganisms is still poorly understood. To study this hypothesis, we evaluated the effects of microorganisms and Cd (0, 0.25, 0.5, 1.0, 2.0, 5.0, and 10.0 mg kg-1 of Cd) exposure on the soil microbial community using Illumina HiSeq high-throughput sequencing. Results Our results indicated that Cd-contaminated soil affected the soil microbial diversity and composition, and bacterial diversity was affected more than fungal diversity in Cd-contaminated soil, especially according to Shannon indices. The abundance of the soil microbial community decreased and the composition changed according to the relative abundances at the phylum level, including those of Saccharibacteria and Gemmatimonadetes in bacteria and Mortierellomycota in fungi. The LEfSe algorithm was used to identify active biomarkers, and 45 differentially abundant bacterial taxonomic clades and 16 differentially abundant fungal taxonomic clades were identified with LDA scores higher than 4.0. Finally, a heatmap of Spearman's rank correlation coefficients and canonical discriminant analysis (CDA) indicated that some key biomarkers, Arenimonas, Xanthomonadales, Nitrosomonadaceae, Methylophilales, Caulobacterales, Aeromicrobium, Chitinophagaceae, Acidimicrobiales, Nocardioidaceae, Propionibacteriales, Frankiales, and Gemmatimonadaceae, were positively correlated with the total and available Cd (p<0.05) but negatively correlated with AK, AP, and pH (p<0.05) in the bacterial community. Similarly, in the fungal community, Tubaria, Mortierellaceae, and Rhizophagus were positively correlated with the total and available Cd but negatively correlated with AK, AP, TK, and pH. Conclusion Cd contamination significantly affected microbial diversity and composition in ginseng-growing soil. Our findings provide new insight into the effects of Cd contamination on the microbial communities in ginseng-growing soil.

“…Due to groundwater contamination in Maner block of Patna, not only soil but food items have also become contaminated with As Singh and Ghosh 2012). In a recent study by Tyagi et al (2020), signi cant As accumulation was reported in rice grains and rice-based food products (chuda and laiya) from Patna, Bihar and health hazards and carcinogenic risks were found to be higher than recommended safe limits. Considering the lack of survey of large parts of Bihar, the present work was planned to determine the level of As in the agricultural lands of the Gangetic plains in Bihar to get recent status of As contamination.…”

Arsenic (As) is a nonessential and toxic metalloid found in sediments, soils and aquatic environments. The contamination of As is a serious problem in South and Southeast Asia threatening the health of millions of people. In this study, 71 soil samples were collected from agricultural fields from Bihar, India situated in the middle Gangetic basin to understand the status of As contamination. The 71 samples from Bihar were taken from three districts; Buxar (n = 21), Bhojpur (n = 34) and Patna (n = 16). Arsenic concentration in soil samples was determined by the wavelength dispersive X-ray fluorescence (WD-XRF) method. The pH, oxidation reduction potential (ORP), organic matter (OM) and cation exchange capacity (CEC) of the samples were also analysed. The mean and range of As concentration were found to be 16.72 mg kg− 1 (13.9–19.4 mg kg− 1), 17.18 mg kg− 1 (13.9–21.1 mg kg− 1) and 17.16 mg kg− 1 (14.8–20.5 mg kg− 1) in Buxar, Bhojpur and Patna, respectively. Of the 71 samples from Bihar, five samples had As levels equal to or higher than the maximum permissible limit i.e. 20 mg kg− 1 for agricultural soil. These five samples were taken from the village of Salempur, Benwaliya, Gundi, Daulatpur and Katesar. To assess the contamination level, various indices like contamination factor, ecological risk assessment and geoaccumulation index were calculated, which indicated “moderate to high” As contamination in the studied areas. The study provides information about the As contamination scenario in middle Gangetic basin and proposes to conduct more comprehensive surveys to understand As contamination in the hugely populated state of Bihar.
