Introduction

“Contracting Parties were invited

to inform on … sources and pathways … of pharmaceuticals to the Baltic Sea environment”

impact of medicinal residues on

the marine environment:

4th most serious problem (after

industrial discharges, eutrophication and over-fishing)

Medicine use: agriculture

Pigs & chickens consume most
WSP Environmental produced

Monitoring

Predominantly, but not only project based
Detection & monitoring methods
SEPA monitors:
sludge & outgoing water
from 9 UWWTP since 2004
Some antibiotics and NSAIDs
Estrogenic & androgenic activity in outgoing water

Measures

(My wife’s pers. comm.: Pharma companies like their

molecules to be as stable as possible!)

Impossible to influence label information
Shortage of environmental information for many

substances

National management plans for unused medicines

are necessary, so they don’t end up down the drain!

Measures

Improvements to treatment at

medium to large UWWT are possible & (cost?) effective:

Ozone treatment (test + drift: Linköping)
Carbon filters (test: Osby & Bromölla)
Off mains drainage more difficult to

solve.
