Coastal sediment samples contained mParaben, OP, 4-MBC, BP-3, BP-1, BPA, OMC, and E1 (< 0.2–11 ng g⁻¹ d.w.), and mParaben, OP, and BP-3 were found to bioaccumulate (3.8–21.3 ng g⁻¹ d.w.) in green lipped mussels. Tucumã seed-activated carbons showed to be cost effective and highly efficient adsorbents for efficient removal of 2-nitrophenol from aqueous solutions. Therefore antibiotics that are polluting the aquatic environment have gained significant research interest for its removal. Adsorption processes were heterogeneous and controlled by physisorption. Not only the protonated amine groups but also the Cr center of the adsorbents exerted electrostatic attraction with the deprotonated carboxyl groups of contaminants, as elucidated by X-ray photoelectron spectroscopy (XPS). Three plant biomasses (miscanthus, ryegrass and wheat) have been considered for the preparation of five different sorbents evaluated for their potential to sorb cadmium and lead and four emergent organic compounds (diclofenac, sulfamethoxazole, 17α-ethynylestradiol and triclosan) from artificially contaminated water. FA removal was pH, temperature and flow velocity dependent. Mixed solutions of these ECs were treated in different water bodies to test PG as a tertiary treatment option. Activated carbon from the shell of the cashew of Para (SCP) was produced by chemical activation with ZnCl using the ratio of SCP: ZnCl2 1.0:1.5 at 700 °C. A majority of ECs does not have standard regulations and could lead to lethal effects on human and aquatic life even at small concentrations. These effluents contaminated with these organic compounds require special treatment, because the presence of these chemicals in water reduce the light penetration, impairing the photosynthesis of aqueous flora; also the presence of these compounds in water cause an improper visual and organoleptic impact for its use; also these chemicals increase the chemical oxygen demand of the aquatic environment, decreasing remarkably the life of aquatic beings. Environmentally friendly and low-cost catalysts are important for the rapid mineralization of organic contaminants in powerful advanced oxidation processes (AOPs).
