Risk assessment of As, Cd, Cr, and Pb via the consumption of seafood in Haikou

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: Aug. 22, 2024

In order to mitigate the risk of excessive heavy metal intake, a study was conducted assess levels arsenic (As), cadmium (Cd), chromium (Cr), and lead (Pb) contamination in 23 edible seafood species obtained from markets Haikou. The findings were analyzed evaluate potential health hazards posed local population through consumption. metals detected via inductively coupled plasma mass spectrometry (ICP-MS) for quantification. non-carcinogenic carcinogenic risks humans assessed target hazard quotient (THQ), combined (CTHQ), cancer (TR). results indicated that rank based on median concentration As > Cd Cr Pb. THQ CTHQ showed nine regarding consumption separately, or four targeted ingestion together. TR assessment InAs all presented coastal residents. content bivalves, algae, several crustacean (Mantis Shrimp, Orchid Crab, Red spot Swimming Crab) fish (Japanese Scad, Pacific Saury), most bivalve (Razor Clams, White Fan Shells, Oysters, Blood Clams) risk. As, Cd, Pb, Haikou Necessitating stricter should be management detection capability monitoring will improved.

Identification of nutritional characteristics of Haliotis discus hannai in different China sea areas and health risks of heavy metal accumulation

Journal of the Science of Food and Agriculture, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 10, 2025

The nutritional compositions of abalones (Haliotis discus hannai) vary with geographical origins and environmental factors. Traceability is an important part food safety, the heavy metals in aquatic environment pose a threat to living organisms. Therefore, we present comparative analysis nutrient metal content from three different sea areas China: Bohai Sea, East China South Sea. This study uniquely addresses correlation between composition accumulation. By employing weighted gene co-expression network analysis, reveal biological implications exposure, specifically focusing on chromium, copper (Cu), manganese, zinc, arsenic (As), cadmium, lead. Betaine, glycine, glycogen appeared comparisons. abalone Sea had highest betaine, contents glycine glycogen. Among measured metals, accumulated viscera were significantly higher than that muscle, except Cu, As showed high target hazard quotient carcinogenic risk. might be indicators for origin traceability abalone. Abalones provide value. Cu accumulation patterns health risks, brought oxidative stress Our findings not only contribute understanding safety quality but also novel approach assessing impact marine sources. © 2025 Society Chemical Industry.

Occurrence, Distribution and Ecological Risk Assessment of Contaminants in Baiyangdian Lake, China

Water, Journal Year: 2022, Volume and Issue: 14(21), P. 3352 - 3352

Published: Oct. 22, 2022

Understanding the ecosystem risk of contaminants in surface water lakes scenic areas is important for environmental management. Here, a comprehensive ecological assessment evaluation method was established to assess 14 quality indicators Baiyangdian Lake spring, summer, and autumn. The results show that indices ammonia nitrogen permanganate exceed Class III standard limit quality. generally state mesotrophication, some are slightly eutrophic; degree eutrophication higher summer autumn than spring. lake at inlet eutrophic polluted, with an inferior Heavy metals almost not detected Lake. heavy metal pollution Nanliuzhuang Caiputai those other areas. quotient petroleum high. Level 4, owing continuous development aquaculture tourism recent years. We should start monitoring, management, strengthening supervision achieve planning goals
