In older homes that have not had their galvanized drain and sewer lines replaced with PVC, finding the sewer cleanout can be challenging. The only point of access to the sewer line is often located on the roof,
she thought little of the semiconductor manufacturing plant across the street. Even after the company’s buildings were demolished and a chain-link fence went up around the campus, she still had no knowledge of the toxic dangers lurking beneath her feet — let alone of the fact that they...
Purple area indicates the known electron pool generated from OM for heterotrophic denitrifiers, while the blue represents the previously concealed electron pool contributed by toxic sulfide and non-toxic sulfur compounds for F-SOHDs. ΔG0(a) and ΔG0(b) denote standard Gibbs free energy change ...
30, the high input of organic matter and seasonal oxygen depletion may result in the intermittent release of toxic H2S from anoxic benthic sediments into the overlying water column, impairing the activity of many microorganisms. This phenomenon, known as sulfidic...
created an environmental catastrophe by opening up a natural underground oil reservoir. The pit released not only oil, but also methane and hydrogen sulfide to the surface. About 350 people had to evacuate to escape the toxic gases. That sinkhole was caused by an underground mine collapse. [Dra...
We know that microplastics are global, increasingly toxic over time, and impacts to wildlife are pervasive, leading to the collective conclusion that plastic in the environment causes harm. We also know that capturing microplastic downstream is extremely difficult and requires upstream intervention. ...
The present invention discloses auxiliary devices to improve drainage operation which are integral with the sewage and rain waters separation system for the achievement of the following purposes: 1.- To avoid emanation of toxic gases, polluting agents such as virus, and microbes which are harmful ...
Microbeads, or tiny plastic particles, have become a huge source of plastic pollution over the years. Microbeads make their way to our oceans through sewer lines. And they are often found in face scrubs, toothpaste, and body washes.
Happy Earth DayThe Good News Here’s the good news: our air is cleaner, our lakes are purer, our forests are healthier, endangered species are recovering, toxic emissions are down, and acid rain has diminished dramatically. And yet, if you’ve looked at a newspaper or watched the evening...
Here we have discussed solutions to microplastics in freshwater ecosystems, which largely form in terrestrial environments from primary or secondary microplastics. We know that microplastics are global, increasingly toxic over time, and impacts to wildlife are pervasive, leading to the collective conclusion...
