Heavy metals concentration and human health risk assessment in selected shrimp species of Pakistan.
Food Addit Contam Part B Surveill
December 2024
Department of Zoology, Government College University Lahore, Lahore, Pakistan.
Heavy metal pollution in marine organisms poses a significant threat to both ecosystems and human health. Dumping untreated sewage into the sea pollutes coastal waters with toxic metals. This study examined the levels of chromium (Cr), lead (Pb), nickel (Ni), mercury (Hg), arsenic (As) and copper (Cu) in three shrimp species of genus i.

Objective: To understand the dietary patterns of adults and explore their association with iodine nutritional levels and thyroid function in adults.
Design: We randomly collected 5 ml of adult urine samples and measured urinary iodine concentration (UIC) by cerium arsenate-catalysed spectrophotometry. A serum sample of 5 ml was collected for the determination of free triiodothyronine, free thyroxine and thyrotropin, and diet-related information was collected through a FFQ.

Article Synopsis
- Marine pollutants, particularly potentially toxic elements (PTEs), are becoming a major threat to the Beibu Gulf's environment and its fishery resources due to their harmful effects and ability to accumulate in organisms.
- A study collected 18 species of seafood invertebrates from the Gulf and analyzed the levels of nine PTEs, finding that most were within safety limits, except for arsenic (As).
- The research indicated a significant increase in the concentration of As and chromium (Cr) at higher trophic levels, and it was determined that eating cephalopod, shellfish, and sea cucumber carries a greater risk to human health compared to shrimp and crab.
Risk assessment of As, Cd, Cr, and Pb via the consumption of seafood in Haikou.

In order to mitigate the risk of excessive heavy metal intake, a study was conducted to assess the levels of arsenic (As), cadmium (Cd), chromium (Cr), and lead (Pb) contamination in 23 edible seafood species obtained from markets in Haikou. The findings were analyzed to evaluate the potential health hazards posed to the local population through consumption. The metals were detected via inductively coupled plasma mass spectrometry (ICP-MS) for quantification.

Plantago asiatica seeds (PS) are commonly used as a medicinal plant. This study investigates the efficacy of PS against heavy metal toxicity in white shrimp (Penaeus vannamei). After feeding PS diet (5 g/kg) or basal diet (control group) for 7 days, shrimps were exposed to sublethal concentrations of heavy metals in seawater (As: 12 mg/L, Pb: 250 mg/L, Hg: 0.
