“…The average concentrations of As, Cd, Cu and Zn in the sediment samples of the Nam Kok River were greater than the standard values according to the standards of TPCD [31], TPCD [32] and the EU [33], while the concentrations of Cr, Ni, Mn and Pb in the sediment were lower than the standard values. When compared, the concentrations of potentially toxic elements As and Cd in the sediment of the Nam Kok River near the gold-copper-mine area were higher than those of other research studies Intamat et al [45] and Tengjaroenkul et al [17] determined that As and Cd were the two most prevalent elements in the sediment around the gold mine area of Loei Province, Thailand, and that the concentrations of As, Cd, Cu, Cr, Pb, Ni, Fe, Zn and Mn reported in the Nam Kok River in this study were lower than those of other studies [45,46,50].…”

This study aimed to determine toxic element concentrations in aquatic environments, including water and sediment, and in the Hampala macrolepidota fish, and to evaluate chromosome abnormalities, serum liver enzyme changes and liver histopathological alterations in H. macrolepidota from the Nam Kok River near the Sepon gold–copper mine, Lao People’s Democratic Republic, as compared with a control area without mining activity. The results revealed significant differences (p < 0.05) in As, Ba, Cu, Fe, Mn, Ni, Se and Zn in water, in all of the studied potentially toxic elements in sediment, and in As, Ba, Cd, Cr, Cu, Mn, Ni, Se, and Zn in the fish between the study and control areas. A chromosome assessment demonstrated 6 types of chromosome abnormalities, among which centric gap had the highest total number of chromosome abnormalities. Percentage of chromosome abnormalities, percentage of cells with chromosome abnormalities and serum liver enzymes in H. macrolepidota were significantly different (p < 0.05) between the two studied areas and were higher in the contaminated fish than in the control fish. The observation of liver histopathological changes revealed cellular degeneration, such as nuclear damage, abnormal cytoplasmic mitochondria and the disintegration of rough endoplasmic reticulum. The results indicate that the contamination of potentially toxic elements in the Nam Kok River near the Sepon gold–copper mine area negatively affected chromosomes, serum liver enzymes and liver cell structures in H. macrolepidota.

“…These results suggested that As and Cd as major accumulated metals in the sediment of the Nam Kok river were relatively high, as reported in other research studies. Culioli et al [ 50 ] found a significantly high concentration of As in a river of Corsica under an influence of tailing way of the gold mine, and Intamat et al [ 52 ] and Tengjaroenkul et al [ 57 ] found that As and Cd were the two highest concentrations among the sediment metals around gold mine area of Loei Province, Thailand. Furthermore, Intamat et al [ 52 ], Khamlerd et al [ 56 ] and Phoonaploy et al [ 58 ] reported that concentrations of Cd, Cr, Pb, Ni, Zn and Mn were lower than of the metals reported in this study.…”

The objectives of the present study were to determine the concentrations of heavy metals and metalloids in water, sediment and Osteochilus vittatus fish, and to assess chromosome aberrations, serum biochemical changes and histopathological alterations in O. vittatus from the Nam Kok river near the Sepon gold-copper mine, Lao People’s Democratic Republic compared with the reference area. The results showed that Fe, Mn and Ni in water, As and Cd in sediment as well as As, Cd, Cr, Mn and Ni in O. vittatus muscle samples near the gold-copper mine exceeded standard values. Furthermore, the chromosome assessment in O. vittatus revealed seven types of chromosome aberrations, and the highest total number of chromosome aberrations was a centromere gap. The total number of chromosome aberrations, cell number with chromosome aberrations and percentage of chromosome aberrations in O. vittatus as well as serum liver enzymes between the studied areas were significantly different (p < 0.05). The liver histopathological alterations of the fish near the gold-copper mine revealed atypical cellular structures as nuclear membrane degeneration, rough endoplasmic reticulum disintegration and abnormal cytoplasmic mitochondria. The results of this study suggested that heavy metal and metalloid contaminations from the Sepon gold-copper mine area negatively affect O. vittatus fish in terms of chromosomal defects, serum biochemical changes and liver histopathological appearances.

“…Moreover, exposure to some heavy metal pollutants of water was reported to cause some of these abnormalities in cell behaviour during mitotic division in fish and reproductive system (Cavas & Ergene‐Gozukara, 2003; Ebrahimi & Taherianfard, 2011). Heavy metals cross the cellular membrane (Tengjaroenkul et al ., 2017), inducing genotoxicity through different mechanisms. They can break DNA strands and cause DNA repair problems, as well as slower DNA alterations, DNA methylation patterns, histone modifications and gene amplifications (Sordo et al ., 2001; Tengjaroenkul et al ., 2017).…”

Mitotic chromosomal aberrations and DNA polymorphism (RAPD marker) were carried out on the Nile tilapia Oreochromis niloticus collected from five sites in Minia governorate, Egypt to test their applicability as biomonitors for heavy metal contaminants of water. The diploid chromosome number of O. niloticus population was 2 n = 44. Different types of chromosomal aberrations were recorded (e.g., deletion, ring, centromeric attenuation, end-to-end association, dicentric chromosome, stickiness chromosomes, endomitosis, fragments and chromatid gap). The chromosomal aberrations varied between O. niloticus population collected from five sites, and the most common type was ring (R) chromosomes. Samples obtained from Bahr Yousef and Irrigation drain exhibited the highest aberration frequency. The frequency of chromosomal aberration was positively correlated with the concentration of heavy metals where their concentration in the surface water of Irrigation drain and BahrYousef exceeded the limits defined by WHO as well as the concentration of Pb in muscles. The RAPD marker was also used to identify genetic variation among Nile tilapia samples collected from five different water sources. It created polymorphic and unique bands that can be used as genetic markers to track DNA variations. The dendrogram also revealed that exposure to heavy metal pollution causes gradual accumulation of variance, whereas areas subjected to environmental stress showed higher genetic variation and clustered together.
