Article Synopsis
  • Many marine animals, particularly Cnidarians like jellyfish, can be dangerous to humans and often cause painful burns, especially in tropical waters.
  • Contact with their toxins may lead to acute kidney damage, with varying effects depending on the specific species of Cnidaria involved.
  • Currently, there's one specific antitoxin for Cnidarian-induced burns, but research is ongoing to develop a universal treatment that could neutralize toxins from various Cnidarian species.

Distribution characteristics of Hg and As in the water-SPM system in the Xiaoqing river estuary and coastal.

Mar Environ Res

December 2024

Frontiers Science Center for Deep Ocean Multispheres and Earth System, And Key Laboratory of Marine Chemistry Theory and Technology, Ministry of Education, Ocean University of China, Qingdao, 266100, China; College of Chemistry and Chemical Engineering, Ocean University of China, Qingdao, 266100, China. Electronic address:

Water and suspended particulate matter (SPM) were collected from Xiaoqing Estuary and its adjacent waters in August 2022 to study the spatial distribution and risk assessment of Hg and As. The content of Hg in SPM samples ranged from 4.7152 to 446.

Objective: Aim: To analyze modern threats of the use of chemical warfare agents on the line of contact during the full-scale invasion into Ukraine.

Patients And Methods: Materials and Methods: The study was carried out with the use of theoretical methods (information retrieval, analytical, descriptive, generalization, system analysis and information synthesis) and the construction of trends with the identification of the coefficient of determination.

Results: Results: Most of damage cases of the military men of the Armed Forces of Ukraine were caused by the enemy's use of such groups of chemical warfare agents with an irritating effect as lacrimators and sternites, more specifically K-51 grenades with chloropicrin (PS) and 2-chlorobenzalmalononitrile (CS), RGR grenade with 2-chlorobenzalmalononitrile (CS) and RG-Vo (862-3-23) grenades with chloroacetophenone (CN).

Background: Animal venom systems are considered as valuable model for investigating the molecular mechanisms underlying phenotypic evolution. Stonefish are the most venomous and dangerous fish because of severe human envenomation and occasionally fatalities, whereas the genomic background of their venom has not been fully explored compared with that in other venomous animals.

Results: In this study, we followed modern venomic pipelines to decode the Synanceia verrucosa venom components.

Historical trend of ecological risk caused by copper sediment in Quintero Bay, Chile, associated with a copper smelter and refinery.

Mar Pollut Bull

December 2024

Laboratorio de Ecotoxicología y Monitoreo Ambiental, Departamento de Ciencias Ambientales, Facultad de Recursos Naturales, Universidad Católica de Temuco, Casilla 15-D. Rudecindo Ortega, 02950. Temuco, Chile.

The Ventanas copper smelter began its activities in Quintero Bay in 1960, and it is estimated that it has released around 152 tons of copper per year into the waters of the bay since then. The increasing copper concentrations in the sediments exceed international standards and pose a potential danger for marine fauna. The object of this work carries out a present and historical ecological risk assessment of copper concentrations in the marine sediment of Quintero Bay.
