Background: Paracetamol (APAP) is the most famous drug used in the world to relieve of pain and used as an antipyretic. Paracetamol overdose induces liver damage and is a well known hepatotoxic drug. This study was aimed to determine the incidence of acidosis in acetaminophen overdose with the time of NAcetyl Cystiene (NAC) administration and correlation of late acidosis and death in acetaminop...

Biochemical reactions that occur in sewer pipes produce a considerable amount of hydrogen sulfide gas (H2S corrosive and poisonous), methane gas (CH4 explosive and a major climate change contributor), carbon dioxide (CO2 a major climate change contributor), and other volatile substances (collectively known as in-sewer gases). These toxic gases lead to contamination of natural environment, sewer...
