Summary: This study investigated the levels of heavy metals in the surface water and sediment of the eastern Bay of Bengal coast in Bangladesh. It found that the concentrations of heavy metals in the water exceeded acceptable limits, indicating that the water is unsafe for various uses. However, the sediment showed low levels of contamination. Further inventorying of heavy metals is needed for holistic risk assessment and management.

Summary: In this study, a combination of electrokinetic and chemical immobilization was used to remediate Cd and Pb polluted river sediments. The immobilization ratios for Cd and Pb were achieved by adjusting the concentrations of the immobilization reagents and the applied voltage. The enhancement effect of the electric field is mainly due to the increased contact between the immobilization reagents and the heavy metals.

Summary: This study investigated the spatial distribution, chemical fraction, ecological risks, and potential sources of heavy metals in surface sediments and sediment cores in Dingzi Bay, Shandong Peninsula. The results showed that Cd and As posed high environmental risks in both surface sediments and sediment cores, with high concentrations mainly found in the middle and the mouth of the bay. The source identification revealed that shipping and aquaculture were the main sources of most heavy metals, while industrial pollution contributed to the levels of As and Ni. Furthermore, the correlation coefficients indicated that the presence of fine particles, total nitrogen, total organic carbon, total phosphorus, and acid-volatile sulfides significantly increased the bioavailability of most heavy metals in surface sediments.

Summary: Anthropogenic activities release heavy metals into the atmosphere, and Pb and Zn isotopes can be used to determine their sources. The study found that the Pb in sediment cores from a lake in South China is mainly from trans-boundary transportation, with 72.3% coming from previously industrialized countries, indicating a significant legacy of heavy metals in China since 1900. Additionally, Chinese gasoline still contributes to heavy metal pollution, and China's mining and smelting activities have steadily increased their contribution to Pb since 1980.

Summary: A detailed study of a sediment core from Daya Bay in South China has shown three stages of heavy metal deposition over the past century. Prior to the 1980s, heavy metal concentrations were low with limited influence from human activities. From the 1980s to 2000, metal pollution increased, primarily due to anthropogenic activities such as oil and petrochemical industries and fuel combustion. Atmospheric deposition and mariculture also contributed to the increase in certain heavy metals. Since 2000, heavy metal concentrations have declined and stabilized. However, ongoing anthropogenic input of copper and lead poses a moderate pollution risk. The modified pollution index and modified ecological risk consistently indicate a moderate ecological risk from heavy metals in Daya Bay over the past 70 years.

Summary: Ice scours are formed when floating icebergs or sea ice hummocks penetrate unlithified seabed sediments. The traditional classification of ice scours based on water depth does not consider current climatic changes. Using Pb-210 dating, the studied ice scour in the Kara Sea is estimated to have formed around 1810 AD. The rate of sedimentation in the ice scour is approximately 0.33 cm/year.

Summary: The study aimed to analyze the impact of mercury concentration on the fluctuating asymmetry (FA) of the Corocoro grunt Orthopristis ruber in a eutrophicated bay in Southeast Brazil. The results showed no significant influence of THg on FA, but there were significant differences in THg levels between the two areas. The higher THg levels in Vermelha Beach may be due to hydrodynamic factors increasing the bioavailability of THg from sediment.

Summary: The Guandu River, a major water source for over nine million people in Rio de Janeiro, has been heavily polluted for more than two decades, leading to high levels of phosphorus, cyanobacteria, and enteric bacteria. The use of Phoslock has proven ineffective in reducing phosphorus levels, and water extracted from the river has unpleasant odors and tastes. Proposed solutions include constructing sewage treatment plants, implementing strict water quality monitoring, environmental recovery efforts, and establishing protected areas to improve water quality.

Summary: Firearms and ammunition identification plays a crucial role in solving crimes and confirming offenders. Qualitative analysis and standards can be used to investigate cases when suspect weapons and ammunition are found at crime scenes. In cases where only ammunition fragments are discovered, alternative methods such as analyzing the elemental composition of lead alloy and verifying lead isotopic ratios are necessary. This study reviews basic ballistics concepts, conventional ballistic confrontation techniques, chemical analysis of ballistic fragments, and the use of lead isotopic analysis in ballistic identification.

Summary: Sediments collected from the Potiguar Basin in northeastern Brazil were found to be rich in organic matter and metals, with metal concentrations increasing with depth. The distribution of iron (Fe), chromium (Cr) and copper (Cu) suggests some changes along the sediment transport, with Fe and Cr being less affected by accumulation in deeper sediments.
