    Area of Science:

    • Environmental Chemistry
    • Analytical Chemistry

    Background:

    • Organic matter in water bodies can originate from various sources.
    • Pesticides pose a risk to aquatic ecosystems and human health.

    Purpose of the Study:

    • To develop a method for separating organic matter from water samples.
    • To identify and quantify specific contaminants, such as the pesticide endrin.

    Main Methods:

    • Carbon adsorption was employed for organic matter separation.
    • Column chromatography, Thin-Layer Chromatography (TLC), Infrared (IR), and Ultraviolet (UV) spectroscopy were used for analysis.

    Main Results:

    • The carbon chloroform extract (CCE) was fractionated into solubility groups.
    • The aromatic fraction was further analyzed.
    • Endrin was detected in river water (0.7 ppb) and tap water (1.5 ppb).

    Conclusions:

    • The carbon adsorption method is effective for isolating organic compounds from water.
    • The presence of endrin in both river and tap water highlights potential contamination issues.
