Global mercury concentrations in biota: their use as a basis for a global biomonitoring framework

Abstract An important provision of the Minamata Convention on Mercury is to monitor and evaluate effectiveness adopted measures its implementation. Here, we describe for first time currently available biotic mercury (Hg) data a global scale improve understanding efforts reduce impact Hg pollution people environment. Data from peer-reviewed literature were compiled in Global Biotic Synthesis (GBMS) database (>550,000 points). These provide foundation establishing biomonitoring framework needed track concentrations biota globally. We exposure taxa identified by Convention: fish, sea turtles, birds, marine mammals. Based GBMS database, are presented at relevant geographic scales continents oceanic basins. identify some effective regional templates monitoring methylmercury (MeHg) availability environment, but overall illustrate that there general lack initiatives around world, especially Africa, Australia, Indo-Pacific, Middle East, South Atlantic Pacific Oceans. Temporal trend generally limited. Ecologically sensitive sites (where have above average MeHg tissue concentrations) been throughout world. Efforts model quantify ecosystem sensitivity locally, regionally, globally could help establish efficient programs. present network includes three-step continental approach integrate existing prioritize filling gaps linked with key sources. standardized builds an evidence-based evaluation assess Convention’s progress

Using Crocodylians for monitoring mercury in the tropics

Ecotoxicology, Journal Year: 2023, Volume and Issue: 32(8), P. 977 - 993

Abstract Mercury contamination is a widespread phenomenon that impacts ecosystems worldwide. Artisanal Small Scale Gold Mining (ASGM) activities are responsible for more than third of atmospheric Hg emission. Due to toxicity and its broad elevated prevalence in the environment resulting from ASGM tropics, biomonitoring essential better understand availability methylmercury (MeHg) form environment. The Minamata Convention was ratified with objective “ protect human health anthropogenic emissions releases mercury compounds ”. Biomagnification MeHg occurs through trophic food web, where it biomagnifies bioaccumulates top predators. To monitor environmental contamination, studies have evaluated use living organisms; however, reptiles among least documented vertebrates regarding exposure. In this review we evaluate crocodylians tropical ecosystems. We found out 28 crocodiles species, only 10 been contamination. remaining challenges when using taxon inconsistencies applied methodology (e.g., wet versus dry weight, tissues used, quantification method). However, due their life history traits, particularly relevant monitoring regions occur. conclusion given ecological socio-economic importance, at great risk excellent bioindicators
