Article Synopsis
  • The Great Barrier Reef's water quality is affected by pollution from farms, especially things like sediment, nutrients, and pesticides.
  • There are also new kinds of pollution called contaminants of emerging concern (CECs) that are coming from farms and cities, which could harm marine life.
  • The study highlights the need for better monitoring of these CECs and suggests collecting more data to understand their impact on the environment.

Background: The speciation of dissolved sulfide in the water immediately surrounding deep-ocean hydrothermal vents is critical to chemoautotrophic organisms that are the primary producers of these ecosystems. The objective of this research was to identify the role of Zn and Fe for controlling the speciation of sulfide in the hydrothermal vent fields at the Eastern Lau Spreading Center (ELSC) in the southern Pacific Ocean. Compared to other well-studied hydrothermal systems in the Pacific, the ELSC is notable for unique ridge characteristics and gradients over short distances along the north-south ridge axis.

Pseudopolarography was used to detect Cd2+ complexes in samples collected at several locations along the Potomac River in June and September, 2004. Irrespective of site and sampling time, no weak inorganic Cd2+ species were present. However, up to two stable Cd(2+)-organic complexes were detected at each site.
