Abstract
Histopathological biomarkers of toxicity in fish organs are a usful
indicator of environmental pollution. Nile tilapia, Oreochromis niloticus
exposed for one month to sediments from the Mae Klong River,
Samutsongkram province, South West Thailand, which contained
elevated levels of heavy metals (lead and chromium), developed
abnormalities of the gills, liver and kidney. In the gill filaments, cell
proliferation, lamellar cell hyperplasia, and lamellar fusion were
observed. In the liver, there was vacuolation of hepatocytes and nuclear
pyknosis. Kidney lesions consisted of dilation of Bowman’s space and
accumulation of hyaline droplets in the tubular epithelial cell. No
recognizable changes were observed in muscle tissue. Despite these
histopathological changes, no firm correlation between levels of heavy
metals in sediments and those in fish tissues could be established.
