Researchers have long been using impact studies to study the effects of climate change on cocoa growth. These studies mimic conditions predicted at the end of the century1 such as higher levels of drought and higher levels of atmospheric CO2. Studies have shown that increased levels of CO2 may help offset the negative effects of reduced water availability on the ...

There are many types of air quality monitors available, but which one is the best choice for measuring gaseous air pollutant concentrations? There are two classes of such air quality monitors: sampling monitors and in-situ monitors (“in-situ” = “in the original position”). Sampling monitors utilises a manifold through which the air to be analysed is pumped. A small air ...

In this work, a natural zeolite, modified and loaded with iron (NZ-A-Fe) as a heterogeneous catalyst, was characterized for its suitability as a permeable reactive barrier (PRB) material for treatment of aromatic hydrocarbons in groundwater. Adsorption and oxidation processes were analyzed. Batch adsorption tests for benzene, toluene and xylene (BTX) aqueous concentrated solutions were ...

All new OTT sensors provide a bus-capable interface, either SDI-12 or the RS 485 based OTT SDI . The special Master Modul of the OTT netDL enables the connection of several sensors to every bus (SDI-12 or OTT SDI). Connect for example an OTT Pluvio² and a Lufft WS510 sensor to one OTT netDL and you get a compact, efficient weather station. Just talk to your personal contact at OTT Hydromet ...

At the moment, nearly all model-based scenarios that limit global warming to 2 °C or less use negative CO2 emission technologies (NETs), particularly bio-energy with carbon capture and storage (BECCS). Still, investments in these technologies continue to be relatively small, and concerns are being raised regarding the large-scale application of such technologies. If no explicit policy ...

The large global warming potential of nitrous oxide (N2O) is currently of general concern for the water industry, especially in view of a new regulatory framework concerning the carbon footprint of water resource recovery facilities (WRRFs). N2O can be generated through different biological pathways and from different treatment steps of a WRRF. The use of generic emission factors (EF) ...
