Medical waste has increased
greatly in the past 10 years, partly because hospitals use more disposable items, such as
syringes, cutlery, food trays, bedpans, and even linen. The public especially fears
medical waste, such as syringes washing up on beaches, but the likeliness of acquiring
AIDS or hepatitis in this way is very small. The real danger, which has received far less
notice, stems from the 6,000 substandard medical-waste incinerators at US hospitals.
Usually concentrated in populous urban areas, they spew tons of toxic emissions, including
dioxin, heavy metals, and acid gases, into the air, averaging 10 to 100 times more per
gram waste burned than emissions from well-controlled municipal waste incinerators.
Hospital incinerators also leave large quantities of toxic ash that can contaminate
surface water and ground water when dumped in landfills.
Switzerland and Germany offer a better
model for handling medical waste, sending it to regional incineration facilities with
advanced air-pollution control technologies. Both countries require complete manifests of
transported wastes to insure that all medical refuse goes through the system. Small
generators of medical waste such as labs, nursing and funeral homes, and medical and
veterinary clinics, could also send their refuse to regional treatment sites.

Implications
Environmental issues are complex problems that span international boundaries. The solution
to these problems will only come from interdisciplinary collaboration and inter-national
discussion. Universities must continue to work toward trans-disciplinary collaboration,
and not all are taking the lead in their communities. Politicians must learn to keep
science separate from pork barreling, and must rely on experts for informed decisions on
funding and sponsorship of policies.
