Chlorine dioxide has been reported as very
efficiently removing pesticides and other organic compounds
from water matrixes. Due to pesticide toxicity
and potential toxicity of their degradation products, it is
important to monitor these compounds as environmental
pollutants in ground and surface waters. Evaluating
the effects of chlorine dioxide treatment is necessary,
and toxicity studies are used to ascertain the severity of
effects of intermediates due to incomplete degradation
of the parent compounds. In this paper, for the first time,
chlorine dioxide is applied and evaluated for the removal
of chloroacetamide herbicides (pethoxamid and
metazachlor) from waters (deionized water and Sava
River water). The degradation degree of herbicides
was measured by high-performance liquid chromatography,
the main degradation products were identified
using gas chromatography with a triple quadrupole mass
detector, and the degree of mineralization was
monitored by total organic... carbon analysis. Four and
two degradation products were identified after
pethoxamid and metazachlor degradation, respectively.
Total organic carbon analysis showed mineralization
occurred, but it was incomplete. The mineralization
and the characteristics of the degradation products obtained
were tested using Daphnia magna and showed
lower toxicity than the parent herbicides. The advantage
of the applied treatment was a very high degradation
percentage for pethoxamid removal from deionized water
and Sava River water (100% and 97%, respectively),
with higher mineralization efficiency (65%) than
metazachlor. Slightly lower degradation efficiency in
the Sava River water was due to chlorine dioxide oxidizing
the herbicides and dissolved organic matter
simultaneously
