Crosslinked Poly(Acrylic Acid‐Co‐Acrylamide) Applied to Remove Hg(II) and the Effects of Its Exposure on Girardia tigrina

open access: yesPolymer Engineering &Science, Volume 65, Issue 12, Page 6964-6979, December 2025.
The polymeric adsorption of Hg(II) and the assessment of ecotoxicity. ABSTRACT In this study, an adsorbent was produced by the copolymerization of acrylic acid and acrylamide, followed by cross‐linking. The impact of pH, duration of contact, concentration, presence of interfering ions, and reuse was investigated.

Trophic Transfer of Arsenic from an Aquatic Insect to Terrestrial Insect Predators. [PDF]

open access: yes, 2013
The movement of energy and nutrients from aquatic to terrestrial ecosystems can be substantial, and emergent aquatic insects can serve as biovectors not only for nutrients, but also for contaminants present in the aquatic environment.

Aquatic food security:insights into challenges and solutions from an analysis of interactions between fisheries, aquaculture, food safety, human health, fish and human welfare, economy and environment [PDF]

open access: yes, 2016
Fisheries and aquaculture production, imports, exports and equitability of distribution determine the supply of aquatic food to people. Aquatic food security is achieved when a food supply is sufficient, safe, sustainable, shockproof and sound ...

Introduction and Expression of a Rabbit β-globin Gene in Mouse Fibroblasts [PDF]

open access: yes, 1979
The cloned chromosomal rabbit ß-globin gene has been introduced into mouse fibroblasts by DNA-mediated gene transfer (transformation). In this report, we examine the expression of the rabbit gene in six independent transformants that contain from 1 to 20

Improvements in the methylmercury extraction from human hair by headspace solid-phase microextraction followed by gas-chromatography cold-vapour atomic fluorescence spectrometry [PDF]

open access: yes, 2004
Improvements in the methylmercury extraction from human hair by solid-phase microextraction followed by gas chromatography coupled to cold-vapour atomic fluorescence spectrometry (GC-CVAFS) have been carried out. They consisted in the optimisation of the

Deep sea cold seeps are a sink for mercury and source for methylmercury

open access: yesCommunications Earth & Environment
The effect of seafloor cold seeps on the biogeochemical cycling of mercury (Hg) remains enigmatic. Here we demonstrate substantial enrichments of mercury and methylmercury, along with the presence of microbes capable of metabolizing mercury in sediments ...
