Sugar can be used as a weed killer, particularly broad leaf weeds, rather than grasses or perennials. It is a carbon nutrient that contains no nitrogen. Sugar can limit the growth of plant that do not tolerate low nitrogen environments. This is because microorganisms in soil are forced to source their necessary nitrogen from soil. This leaves little for ...

Maybe a little, but not much. Personal care products that have a strong odor are typically associated with volatile organic compound (VOC) emissions. VOCs are not really greenhouse gases, because they are reactive and very short-lived in the presence of sunlight. However, VOCs do have a small indirect effect on global warming because they increase ...

So far, I thought there won't be any studies on the overall scenario of waste disposals. After searching in depth, I have found studies on illegal waste dumping sites in Polish forests. Hope these will be helpful. Jakiel et al. (2018) assessed the spatiotemporal distribution of wastes in the Ojcow National Park, Poland. Number of dumping sites and volume of ...

I think there is a bit to unpack in your question, starting with the definition of terms. Just starting off with the title question, yes - examples include the 1948 Donora Smog event, and the 2006 Delhi Smog event. The use of the word disaster is usually reserved for catastrophes, not exceedances. There are a couple of problems with just claiming that ...

The assumption is that these contaminants will leach into the ground and reach a source of drinking water. Or they will enter the food chain, by accumulating in plants, eaten by herbivores, eaten by carnivores and/or humans. So the risk is ingestion of material X, with material X being able to affect humans health if its concentration is larger than Y. There ...

If there are any beehives in the area, it's likely the bees will discover this and go to it preferentially over other sources of sugars. That will reduce their utility to the beekeeper by removing their pollinating effects and by filling the combs with artificial honey that is likely an unappetizing color to boot. Finally, it's possible that the ingredients ...

I had an 2 hour meeting with the local park ranger about this and the other exhibits, the ball is getting removed due to a high number of insects (mainly butterflies and moths) getting stuck on it and dying.

The POLLUTID key is used to specify some regular options. Some examples: PM2.5 can only evaluate averages greater than 24 hours (if you try to generate hourly averages it throws an error). NO2 forces the use of options to simulate the conversion of NOx to NO2. SO2 triggers the use of a 4-hour half-life for SO2 decay in urban zones. All pollutants (gases ...
