At nitrogen gas exposures to very high concentrations for short periods of time, the onset of symptoms is very sudden and marked. Convulsions, unconsciousness, and respiratory arrest occur within a short time and death may follow rapidly. Diagnosis of Nitrogen Oxide Gas Exposure The diagnosis is m...
This paper discusses a specific research program started on February 4, 1999 (and with some continuing to date) in AMERICAN laboratories to evaluate the effects of long-term, soaking exposure of commonly supplied sewer pipe linings to very low pH sulfuric acid. Many other researchers have shown ...
reuse and, as a last resort, recycle). The specific issue of endocrine-disrupting chemicals might be mitigated through responsible disposal and processing, alongside advocating for the use of alternative materials and replacing additive chemicals ...
Planting trees and restoring wetlands can increase the capacity of sewer systems because more of the rainwater can be absorbed into the ground and tree roots before reaching the sewers.One of the UN’s Sustainable Development Goals is to ensure that everyone in the world has access to toilet ...
(2017) reported a decrease in soil pH in the presence of HDPE pellets after 6 and 12 weeks of exposure to photo- and thermo-oxidative conditions. Boots et al. (2019) also observed that the pH of the soil was 0.62 units lower than that of the control after exposure to HDPE in soil ...
We found that concentrations of these toxicants vary significantly depending on the type of EC device, the type of EC liquid, and the smoking behaviour of the user. Exposure to these vapours can cause inflammation and oxidative damage to in vitro and in vivo cells. EC aerosol can also ...
mimic gravity sewer conditions and to cultivate sediments, were operated in parallel (Fig. 1). Each reactor had a working volume of 3.2 L including 0.5 L gas volume to ensure an ample amount of oxygen in the gas phase during the reactor opera- ...
Today, human activities also contribute to climate change: fossil-fuel combustion (coal, oil, and gas) increasing the concentration of CO2; deforestation reducing CO2, absorbing capacity of forested areas; industrial activity and biomass burning resulting in emissions of gases such as carbon monoxide ...
Another major health concern is the musculoskeletal disorder such as the osteoarthritis. Exposure to infections in the sewer is also common due to the numerous bacteria residing in the sewers. The common infection is the Leptospirosis which is an occupational disease in people who are in contact wi...
Water samples (2 L) were collected weekly from alternate tanks (4 out of 8 tanks) for each treatment during the exposure period on days 0, 7, 14 and 21. Show abstract Endocrine disrupting activities of surface water associated with a West Virginia oil and gas industry wastewater disposal ...
