Conclusions
Detergents are closely related to the environment. From
an environmental point of view, the impact of detergents on
water resources management, their biodegradability, toxicity
and eutrophication caused by detergents is very significant.
Since a large number of synthetic detergents exhibits insufficient
biodegradability, water courses are becoming polluted
with these substances. Even low concentrations of surfactants
were shown to endanger the organisms in the environment.

In order to minimize their concentrations in the environment,
generally valid rules should be implemented to help protect
our environment.
