| Abstract |
|
This study was conducted to investigate the pharmaceutical pollution in the upper Han River which is used
as drinking water for the Metropolitan area and on evaluate the its influences to the human health and ecosystem.
The target materials were 13 species of animal antibiotics as tetracycline, sulfonamide, quinolone antibiotics
and etc. that are considerable in their productivity, drainage to the environment and simplicity for
analysis. And the purposed regions were the upper Han River area, and the South and North Han river area.
And Samples were collected and analyzed at low, medium and high-water seasons. As results, florfenicol
(100%), sulfadimethoxine (88%) and enrofloxacin were the most abundant at medium-water season. At the
high-water season, some sulfuric antibiotics and florfenicol were existed as low concentrations but there were
no increases in concentration or frequency. Concentration variance during a year is not obvious because seasonal
Han river's flow change is not big, though some sulfuric antibiotics increased during dry period. The
most abundant material was tetracycline (2,096 ng/L), and the next was oxytetracyclin (1,236 ng/L), and chlortetracyclin
(793 ng/L) was the third. And for sulfuric antibiotics, concentration of sulfamethoxazole was the
highest as 67 ng/L (avg.), and trimethoprim was also high as 202.3 ng/L (avg). |
