  • How & Why We Measure Suspended Solids

    In case you weren’t sure, Suspended Solids is simply a density measurement used to describe exactly how much waste sludge and particles are in the water, and is measured in milligrams per litre (mg/l), grams per litre (g/l) or percentage solid (%). 1000mg/l = 1g/l = 0.1%. It is used to calculate the amount of material, or load, in a wastewater or industrial system. Suspended Solids ...

  • Oxidative stress response of the aquatic macrophyte Hydrilla verticillata exposed to TiO2 nanoparticles

    The present study investigated the effects of titanium dioxide nanoparticles (TiO2‐NPs) on the oxidative stress response in Hydrilla verticillata. Macrophytes were exposed to different concentrations of TiO2‐NPs (0 mg/L, 0.01 mg/L, 0.1 mg/L, 1 mg/L, 10 mg/L) for 24 h, based on currently predicted levels of nano‐TiO2 in surface waters. Additionally, TiO2‐NPs with varying crystalline statuses ...

  • Materiality Assessment for Dummies

    When I started to work in the area of sustainability, I had no idea what a materiality assessment was, and what all the acronyms like GRI and SASB meant. It occurred to me I probably wasn’t the only one, and now that materiality assessment is such a hot topic, I thought it would benefit others to review. For this, I turned to our Corporate Sustainability Officer at PE International, ...

  • Bioavailability‐based chronic toxicity measurements of permethrin to Chironomus dilutus

    Compared to acute toxicity, chronic exposures to low levels of contaminants are more environmentally relevant but less data are available. Sediment toxicity of the pyrethoid permethrin to Chironomus dilutus was determined. The whole life cycle toxicity testing was conducted with the endpoints covering survival, growth, emergence and reproduction. Permethrin caused 50% lethality in C. dilutus at ...

  • Silicon nanocrystals as light sources: stable, efficient and fast photoluminescence with suitable passivation

    Silicon optoelectronics is an emerging technological platform, which holds promise for providing better performance, mostly in terms of lower dissipation losses, than the traditional electronics. However, a monolithic integrated light source is still missing since bulk silicon is a very poor light emitter due to its indirect bandgap. The situation dramatically changes when the size of the crystal ...
