Sorting states of environmental DNA: Effects of isolation method and water matrix on the recovery of membrane‐bound, dissolved, and adsorbed states of eDNA

open access: yesEnvironmental DNA, 2023
Environmental DNA (eDNA) once shed can exist in numerous states with varying behaviors including degradation rates and transport potential. In this study, we consider three states of eDNA: (1) a membrane‐bound state referring to DNA enveloped in a ...

Multivariate space-time modelling of multiple air pollutants and their health effects accounting for exposure uncertainty [PDF]

open access: yes, 2018
The long-term health effects of air pollution are often estimated using a spatio-temporal ecological areal unit study, but this design leads to the following statistical challenges: (1) how to estimate spatially representative pollution concentrations ...

Exploring Key Soil Parameters Relevant to Arsenic and Cadmium Accumulation in Rice Grain in Southern China

open access: yesSoil Systems, 2022
Paddy soils in some areas of southern China are contaminated by arsenic (As) and cadmium (Cd), threatening human health via the consumption of As- and/or Cd-tainted rice. To date, a quantitative understanding of how soil characteristics control As and Cd

Climatic modulation of recent trends in ocean acidification in the California Current System

open access: yesEnvironmental Research Letters, 2016
We reconstruct the evolution of ocean acidification in the California Current System (CalCS) from 1979 through 2012 using hindcast simulations with an eddy-resolving ocean biogeochemical model forced with observation-based variations of wind and fluxes ...

Preparation and adsorption properties of magnetic chitosan/sludge biochar composites for removal of Cu2+ ions

open access: yesScientific Reports, 2023
The magnetic chitosan/sludge biochar composite adsorbent was prepared using chitosan, Fe3O4, and sludge biochar as raw materials. The composite adsorbent was able to achieve rapid solid–liquid separation under an applied magnetic field.

Effects of eutrophication on sedimentary organic carbon cycling in five temperate lakes [PDF]

open access: yesBiogeosciences, 2019
Even though human-induced eutrophication has severely impacted temperate lake ecosystems over the last centuries, the effects on total organic carbon (TOC) burial and mineralization are not well understood.
