“…The results obtained from the laboratory analysis indicate that O. niloticus from the domestic wastewater canal is contaminated with heavy metals. There are other possible environmental measures of toxicity in addition to the heavy metal concentrations found in this field study (Ansari et al 2004). Heavy metals are well-known environmental pollutants that cause serious health hazards to humans, but their effects are not immediate and can appear after many years (Liu et al 2007).…”

The study aimed to assess water quality parameters and heavy metal contamination in water, sediment and Nile tilapia (Oreochromis niloticus). Heavy metal concentrations in water were compared to Thailand s standard limits, and chromosomal aberrations in O. niloticus from contaminated water were compared with O. niloticus from an unaffected area. The samples were collected from a domestic wastewater canal, water quality parameters were assessed, and heavy metal concentrations (Pb, Cd, Cr, Cu, Fe, Mn, Ni, and Zn) in the water, sediment and fish were analyzed by inductively coupled plasma optical emission spectrometry (ICP-OES). The water quality parameters did not exceed standard values. The concentrations of heavy metals in the water and sediment did not exceed Thailand s standards, but the Ni concentration in the water was higher than the standard limits. Similarly, heavy metal concentrations in O. niloticus were also below the standard limits. Only the Cr concentration in O. niloticus tissues exceeded the standard limits. The diploid chromosome number of O. niloticus from both areas was 2n=44 and the chromosomal damage of O. niloticus in the affected area was higher than that in the unaffected area. There were six types of chromosomal aberrations: single chromatid break, single chromatid gap, centromeric gap, fragmentation, deletion and dicentric chromosomes. The most common chromosomal abnormality in the fish samples from the affected area was single chromatid gap, and the difference in chromosomal breakages in O. niloticus between the areas was significant (p 0.05).

“…As defined by IUPAC, the term heavy metals "is often used as a group name for metals and semimetals (metalloids) that have been associated with contamination and potential toxicity or ecotoxicity" (Duffus, 2002). Heavy metals are a natural part of the marine environment whose concentrations have been constantly increasing due to anthropogenic activities (Ansari et al, 2004). Several metals and metalloids are directly linked to sea-based sources of pollution, such as shipping, offshore oil-and gasindustry, mariculture Hanke, 2016, 2018) and are, therefore, included in the guidelines for environmental status assessment by EU and UNEP/MAP directives.…”

The drive for development and modernization has come at great cost. Various human activities in developed and developing countries, particularly in sub-Saharan Africa (SSA) have given rise to environmental safety concerns. Increased artisanal mining activities, illegal refining, use of leaded petrol, airborne dust, arbitrary discarding and burning of toxic waste, absorption of production industries in inhabited areas, inadequate environmental legislation, and weak implementation of policies, have given rise to the incomparable contamination and pollution associated with heavy metals in recent decades. This review evaluates the public health effects of heavy metals and their mixtures in SSA. This shows the extent and size of the problem posed by exposure to heavy metal mixtures in regard to public health.
