Review of mercury pollution research in Southeast Asian marine environments.

Mercury (Hg) is a global pollutant of widespread concern, and modern Hg levels have been much elevated compared to pre-industrial levels. The majority of environmental Hg assessment has occurred in the developed world within the temperate region, but recent years we have witnessed increases in research activities in polar, subtropical, and tropical biomes. East Asia is currently the biggest emitter of anthropogenic Hg, while intense research is ongoing in China, Korea, and Japan, relatively little has been done in the neighboring regions.

SURGICAL OUTCOMES AND INTRAOPERATIVE PARAMETERS OF THREE-DIMENSIONAL VISUALIZATION SYSTEM VERSUS CONVENTIONAL MICROSCOPES FOR MACULAR SURGERY IN HIGHLY MYOPIC EYES: A Prospective Randomized Clinical Trial.

Purpose: To investigate the surgical outcomes and intraoperative parameters of 3D visualization system for macular diseases in highly myopic eyes.

Methods: In this single-center, prospective, randomized, comparative interventional study, 40 highly myopic eyes (axial length > 26 mm) were randomly assigned to either a 3D visualization system or a conventional microscope group. Surgical outcomes and intraoperative parameters, including the number of indocyanine green injections, surgical time, and epiretinal membrane/internal limiting membrane peeling time, were compared.

Combined effects of polyamide microplastic and sulfamethoxazole in modulating the growth and transcriptome profile of hydroponically grown rice (Oryza sativa L.).

The use of reclaimed water from wastewater treatment plants for irrigation has a risk of introducing micropollutants such as microplastics (MPs) and antimicrobials (AMs) into the agroecosystem. This study was conducted to investigate the effects of single and combined treatment of 0.1 % polyamide (PA ∼15 μm), and varying sulfamethoxazole (SMX) levels 0, 10, 50, and 150 mg/L on rice seedlings (Oryza sativa L.

Impact of geochemistry and microbes on the methylmercury production in mangrove sediments.

Unraveling the geochemical and microbial controls on methylmercury (MeHg) dynamics in mangrove sediments is important, as MeHg can potentially pose risks to marine biota and people that rely on these ecosystems. While the important role of sulfate-reducing bacteria in MeHg formation has been examined in this ecologically important habitat, the contribution of non-Hg methylating communities on MeHg production remains particularly unclear. Here, we collected sediment samples from 13 mangrove forests in south China and examined the geochemical parameters and microbial communities related to the Hg methylation.
