Electrode material impact on microbial fuel cell and electro-Fenton systems for enhanced slaughterhouse wastewater treatment: A comparative study of graphite and titanium.

The treatment of slaughterhouse wastewater is a complex task demanding careful consideration due to its challenging nature. Therefore, exploring more sustainable treatment methods for this particular type of wastewater is of utmost significance. This research focused on the impact of electrode materials, specifically graphite and titanium, on the efficiency of microbial fuel cells (MFCs) and electro-Fenton systems in treating slaughterhouse wastewater.

The effect of work environment on the biochemical profile of workers operating at the Ust-Kamenogorsk Titanium and Magnesium Plant.

This study explored biochemical parameters of blood in workers operating in the main workshops at the Ust-Kamenogorsk Titanium and Magnesium Plant: magnesium (Mg) workshop (furnace operator, chlorinator operator, and electrolyzer operator), titanium tetrachloride workshop (mill operator and titanium (Ti) production operator), and Ti sponge workshop (reduction furnace operator, knockout operator, and crushing machine operator). The control group consisted of 112 male workers, whose duties were not related to similar occupational hazards (plumbers, electricians, janitors cleaning the administrative building, security guards, and carpenters). The activity of gamma-glutamyl transferase, aspartate aminotransferase, alanine aminotransferase, creatine phosphokinase, lactate dehydrogenase, cholinesterase, alkaline phosphate, and α-amylase and the concentration of serum calcium, Mg, phosphorus, and chloride ion were measured.
