Figure 1 Atmospheric layers environment. We learned that scientists now estimate 3-5% of the ozone layer, which protects us from exposure to ultraviolet rays, has been destroyed by chlorofluorocarbons (CFCs), increasing our risk of cataracts and skin cancer.' (See Figure 1.) But what about the volatile anesthetic agents, hydrochlorofluorocarbons (HCFCs), which closely resemble the CFCs? Are the...

Only five studies have been found in the literature which provide any indication of the effectiveness of incineration for rendering infectious hospital waste innocuous. Although there is an indication from these studies for release of bacteria in stack gas, none of the studies identified the bacteria or determined the source of bacteria. The purpose of the present study was to investigate the p...

Transmissible spongiform encephalopathies (TSEs, prion diseases) are a class of fatal neurodegenerative diseases affecting a variety of mammalian species including humans. A misfolded form of the prion protein (PrP(TSE)) is the major, if not sole, component of the infectious agent RecentTSE outbreaks in domesticated and wild animal populations have created the need for safe and effective dispos...

Placenta is a transitory organ which simultaneously separate and connect mother and fetus. It has the major importance in the nutrition of fetus, scavenger waste products from fetus, secretion of hormones and immunological factors, allowing fetus to grow in a sea of maternal immunologic environment and regulating mother metabolism. Also, placenta protects fetus to some infectious agents. It has...

E-waste or electronic waste is a major waste stream resulting from the boom in consumer electronics in the past decades. With the rapid pace of technology innovation and obsolescence that leads to shortened product lifespans, the growing demand for electronics and its resulting waste poses a significant challenge in every stage of its life-cycle from the utilization of raw materials, production...

To the Editor: Health care waste (HCW) is hazardous because of its composition and ability to transmit infectious diseases including HIV/AIDS and hepatitis B and C.1 HCW management comprises seven key stages: segregation, collection, storage, handling, transportation, treatment and disposal. It is important that hospitals segregate HCW into designated categories, with storage in appropriate con...

Patients who self-quarantine were carried out to break the chain from spread of COVID-19 virus, but a new problem arose: solid medical B3 waste originating these patients. If this is not managed properly, it can potentially transmit and be contaminated by infectious substances. Management patients was minimal because most people did know about it, there lack infrastructure government. Therefore...
