Mitigating with macrophytes: submersed plants reduce the toxicity of pesticide-contaminated water to zooplankton.

In ecotoxicology, appreciation is growing for the influence that ecological interactions have on the toxicity of contaminants, such as insecticides, to sensitive species. Most previous studies, however, have focused on factors that exacerbate insecticide effects on species, while factors that may mitigate these effects have been relatively ignored. In aquatic habitats, a small number of studies...

Exploiting Microbes and Plants to Clean up Pesticide Contaminated Environments

This journal is © The Royal Society of Chemistry 2002 Background Microbes and plants are among the most important biological agents that remove and degrade waste materials to enable their recycling in the environment. Whilst these agents are adapted to tackle most naturally occurring substances, many modern synthetic chemicals present a challenge to their remediating capabilities. The fact that...

Optimum water depth ranges of dominant submersed macrophytes in a natural freshwater lake

Macrophytes show a zonal distribution along the lake littoral zone because of their specific preferred water depths while the optimum growth water depths of dominant submersed macrophytes in natural lakes are not well known. We studied the seasonal biomass and frequency patterns of dominant and companion submersed macrophytes along the water depth gradient in Lake Erhai in 2013. The results sho...

Removal of Diazinon Pesticide Using Amino-silane Modified Magnetite Nanoparticles from Contaminated Water

   A magnetically recoverable adsorbent has been prepared by silica-coated magnetic nanoparticles through an amine functionality (ASMNPs). The ASMNPs were characterized by XRD, TEM, SEM, and FT-IR spectroscopy. It was used as an efficient and economical adsorbent for removing O, O-Diethyl O-[4-methyl-6-(propan-2-yl) pyrimidin-2-yl] phosphorothioate (diazinon) from...
