Dr. Hussein A.Jannah's research was selected among the best 100  achievements in Britain after more than seven years of work. 
  The research discussed some chemical substances (washing powders) based on their use after being released into the sewer system through the sewage treatment project and then  to The river and then its access to the drinking water treatment project and thus its access to the consumer, which means exposure to concentrations of those substances, which have an impact on the health of the consumer.
