Heavy metal contamination in some commercial marine fishes of Pakistan.
Anthropogenic activities, such as industrial discharge, cargo handling, and untreated wastewater release, have led to significant heavy metal contamination along the Karachi coastline, posing risks to marine life and human health. Current study evaluated the health risks associated with consuming five fish species (Trichiurus lepturus, Sillago sihama, Acanthopagrus arabicus, Otolithes cuvieri, and Nemipterus japonicus) by analysing muscle tissues for arsenic, chromium, copper, and nickel accumulation. Nemipterus japonicus and Otolithes cuvieri exhibited hazard index (HI) values greater than 1, indicating potential non-carcinogenic risks to adults, particularly due to high arsenic levels. Other species were deemed safe for consumption. Present study emphasises the need for further investigation into contamination sources and recommends regular monitoring of heavy metal levels to mitigate health risks from fish consumption.
期刊介绍：
Food Additives & Contaminants: Part B publishes surveillance data indicating the presence and levels of occurrence of designated food additives, residues and contaminants in foods, food supplements and animal feed. Data using validated methods must meet stipulated quality standards to be acceptable and must be presented in a prescribed format for subsequent data-handling.
Food Additives & Contaminants: Part B restricts its scope to include certain classes of food additives, residues and contaminants. This is based on a goal of covering those areas where there is a need to record surveillance data for the purposes of exposure and risk assessment.
The scope is initially restricted to:
Additives - food colours, artificial sweeteners, and preservatives;
Residues – veterinary drug and pesticide residues;
Contaminants – metals, mycotoxins, phycotoxins, plant toxins, nitrate/nitrite, PCDDs/PCFDs, PCBs, PAHs, acrylamide, 3-MPCD and contaminants derived from food packaging.
Readership: The readership includes scientists involved in all aspects of food safety and quality and particularly those involved in monitoring human exposure to chemicals from the diet.
Papers reporting surveillance data in areas other than the above should be submitted to Part A . The scope of Part B will be expanded from time-to-time to ensure inclusion of new areas of concern.
