Sand and dust storms increasingly threaten global environmental and public health. To date, 150 countries are directly affected, with more than 100 classified as non-dust source regions. With climate change, these storms are expected to become more frequent and severe.

Dioxins and analogous derivatives pose significant concerns due to their impact on human health through both acute and prolonged exposures. They have the potential to resist natural degradation processes; therefore, they tend to accumulate in water, sediments, fish, meat, and human adipose tissue. As a result, concerns to both environmental and human health arise among the scientific community and environmental health organizers.

This study reports the concentration of heavy metals in the tissues of stranded sea snakes that died as a result of exposure to an oil spill on the eastern coast of Sharjah, UAE. Given the limited occurrence of stranded sea snakes observed along Sharjah's eastern coast outside this spill incident, we are using strandings collected from the nearby Arabian Gulf coast of Sharjah to compare the levels of heavy metals in sea snakes affected by the oil spill against their non-oiled counterparts. The sample comprised 14 Arabian Gulf Coral Reef Sea Snakes ), 6 Yellow-bellied Sea Snakes (), and 4 Yellow Sea Snakes ().

The service behavior of ductile metallic materials, when they have previously undergone technological plastic deformation, depends on the deformation conditions. These are represented, among others, by the deformation rate, the process temperature, the applied pressures, and the introduced stresses, as well as other process variables. The investigation of the mechanical properties obtained after plastic deformation is an important means that contains two characteristics: on the one hand, to determine to what extent the parameters of the technological manufacturing process influence the main characteristics of the final component; and, on the other hand, on the basis of these characteristics, to analyze whether the component subjected to plastic deformation will be able to function reliably and safely.

Article Synopsis
  • The study evaluates the levels of organochlorine pesticides (OCPs) and polycyclic aromatic hydrocarbons (PAHs) in tissues of stranded sea snakes in Sharjah, UAE, analyzing samples from 13 individuals of three species.
  • Muscle, liver, and fat tissues were processed using micro-QuEChERs and analyzed with gas chromatography-mass spectrometry (GC/MS), revealing that OCPs were present in higher concentrations while PAHs were detected more frequently.
  • The findings indicate significant bioaccumulation of OCPs and PAHs in sea snake tissues, with variations in OCP types detected based on tissue type and higher concentrations of OCPs compared to previous studies in marine reptiles.
