The College of Education for Pure Sciences, Department of Chemistry, reviewed a doctoral dissertation on "Estimation of Some Water Pollutants Using a Laboratory-Designed Autonomous Microfluidic Microfluidic System." The dissertation, submitted by researcher Rana Tariq Shibli, described a system consisting of a microfluidic channel with micro-sized dimensions. Microcontrollers were used to regulate its operation and flow velocity. The system was tested for its ability to efficiently measure the concentrations of certain pollutants, such as nitrates, nitrites, and phosphates, in selected water samples along the Shatt al-Arab River in Basra Governorate. The study concluded that the laboratory-designed system is economical due to its low consumption of samples and reagents, and environmentally friendly.

The dissertation aimed to study the design of an autonomous microfluidic microfluidic system for estimating the concentrations of nitrate, nitrite, and phosphate ions, and to apply this system to environmental water samples. The results were then compared with traditional methods to evaluate the system's efficiency. The thesis concluded: “Designing a microfluidic system for the estimation of certain pollutants is environmentally friendly because it produces small amounts of waste and consumes small amounts of reagents and samples, and represents a viable alternative compared to traditional methods used in environmental monitoring, highlighting the efficiency and reliability of the proposed approach
