The quantitative and predictive evaluation of heavy metal (HM) pollution threats remains limited in bay ecosystems. In the present study, multiple models were used to evaluate the characteristics, accumulation, and risk assessments of HMs in typical bays in northern China. The results revealed the following: (1) HMs were accumulated in the sediment of the selected bays, and their presence had a moderate ecological risk owing to the high concentrations of Cd and Hg. (2) Quantitative evaluation revealed that HM concentrations in these bays were within the safety threshold; however, the simulated health risks indicated that bivalve HM exposure could not be considered negligible with the probability of high accumulation. (3) HMs showed accumulation heterogeneity in the sediment and bivalves due to the geochemical and physical indexes of the bay ecosystems. Geochemical properties, including sedimentary organic matter (SOM), grain size, and sediment texture, affected Cd and Hg accumulation in the sediment and the bioaccumulation of As in bivalves, whereas physical properties, including temperature and salinity, influenced the bioaccumulation of Cd and Cu through bivalves. Overall, these results provide novel insights into HM pollution in terms of accumulation heterogeneity and support valuable implications to ensure the accurate control of HM pollution in bay ecosystems.

The most common lifestyle change during the Covid-19 pandemic is an increase in people's purchasing power. The strategy that sellers need to pay attention to is product placement. Product placement in stores on a small or large scale is one of the strategies that can affect consumer purchasing decisions. One supermarket in Surabaya experienced an increase in transactions during the pandemic, but there are some products whose sales are not as high as other products due to product placement that is not by the type or function so that when customers want to buy products they have to look for them first, this is not uncommon. customers do not shop or buy products which result in lower transactions and lower supermarket profits. So this research was conducted to provide recommendations for product placement in a layout that suits consumers' wishes, grouping products based on consumer buying habits, and reduce search time. This research was conducted using the Market Basket Analysis (MBA) method. From the results, there are 19 rules which indicate that some products will be purchased if placed close to other products with a 100% confidence level.

“…Rice locally produced in Australia has a relatively lower Ni content than those produced in Southeast Asian countries [ 34 ]. In East Asia, China has generally higher Ni content in food than in the neighboring Japan [ 17 , 35 ]. Overall, the type of food significantly influences the Ni content owing to the different transfer patterns in the ecosystem and characteristics of organisms [ 36 ].…”

Nickel (Ni) is a silver-white metal with high antioxidative properties, often existing in a bivalent form in the environment. Despite being the fifth most abundant metal on Earth, anthropogenic activities, including industrial processes, have elevated Ni levels in environmental media. This study investigated Ni contamination in various food groups in Zhejiang Province, China, mainly focusing on Ni levels in beans, vegetables, aquatic foods, meat products, cereal products, and fruits. A total of 2628 samples were collected and analyzed. Beans exhibited the highest Ni content in all samples. The overall detection rate of Ni was 86.5%, with variation among food categories. For plant-origin foods, legumes had the highest Ni concentration while for animal-origin foods, shellfish showed the highest median Ni concentration. The results indicate generally acceptable Ni exposure levels among Zhejiang residents, except for children aged 0–6. Beans were identified as the primary contributor to high Ni exposure risk. The paper suggests monitoring Ni contamination in food, especially for vulnerable populations, and provides insights into exposure risks in different age groups.
