In the last few decades, pharmaceuticals, credited with saving millions of lives, have emerged as a new class environmental contaminant. These compounds can both chronic and acute harmful effects on natural flora fauna. The presence pharmaceutical contaminants in ground waters, surface waters (lakes, rivers, streams), sea water, wastewater treatment plants (influents effluents), soils, sludges has been well doccumented. A range methods including oxidation, photolysis, UV-degradation, nanofiltration, reverse osmosis, adsorption used for their remediation from aqueous systems. Many commercially limited by toxic sludge generation, incomplete removal, high capital operating costs, need skilled maintenance personnel. Adsorption technologies are low-cost alternative, easily developing countries where there is dearth advanced technologies, personnel, available capital, appears to be most broadly feasible removal method. integrated (WWTPs). Herein, we reviewed literature (1990–2018) illustrating rising contamination concerns efforts emphasizing adsorption.

Wastewater treatment plants (WWTPs) are considered the main sources of chemicals emerging concern (CECs) in aquatic environments, and can negatively impact ecosystems. In this study, WWTP influent, effluent, sludge, upstream downstream waters from recipient were investigated at 15 locations for a total 164 CECs, including pharmaceuticals, personal care products, industrial chemicals, per- polyfluoroalkyl substances (PFASs), pesticides. addition, zebrafish (Danio rerio) embryo toxicity tests (ZFET) applied to influent recipients. A 119 CECs detected least one sample, mean concentrations ranging 0.11 ng/L (propylparaben) 64,000 (caffeine), wastewater samples 0.44 (ciprofloxacin) 19,000 (metformin) surface water samples. Large variations CEC found between selected WWTPs, which be explained by differences composition process. The sludge-water partitioning coefficient (Kd) showed significant linear correlation octanol/water partition (KOW) (p < 0.001), thus could used predicting their fate aqueous solid phase. ΣCEC WWTPs declined on average 60%, based comparisons effluent concentrations. high resulted in, average, 50% higher compared with upstream.

These results provide theoretical basis optimization existing systems different designs, significantly contribute protecting waters.

Presence of pharmaceutically active compounds (PACs) as emerging contaminants in water is a major concern. Recent reports have confirmed the presence PACs natural and wastewater systems, which caused several problems indicating urgent need for their removal. The current review evaluates role chemically modified biosorbents removal water. Reported include plant animal solid waste, microorganisms bio-composite. Bio-composites exhibited better prospects when compared with other biosorbents. Types chemical treatment reported acid, alkaline, solvent extraction, metal salt impregnation surface grafting, alkaline exhibiting results treatments. biosorption processes mostly obeyed pseudo-second-order model Langmuir isotherm process described mainly by ionic interaction. Desorption regeneration capacity are very important selecting an appropriate biosorbent process. Depending on type biosorbent, cost per million liters was estimated US $10–US $200, presents cheap to known processes. However, there conduct large-scale studies removing

The pollution of the aquatic environment has become a worldwide problem. widespread use pesticides, heavy metals and pharmaceuticals through anthropogenic activities increased emission such contaminants into wastewater. Pharmaceuticals constitute significant class can seriously threaten health non-target organisms. No strict legal regulations on consumption release water bodies have been implemented global scale. Different conventional wastewater treatments are not well-designed to remove emerging from with high efficiency. Therefore, particular attention paid phycoremediation technique, which seems be promising choice as low-cost environment-friendly treatment. This technique uses macro- or micro-algae for removal biotransformation pollutants is constantly being developed cope issue contamination. aims this review are: (i) examine occurrence in water, their toxicity organisms describe inefficient treatments; (ii) present cost-efficient algal-based techniques contamination removal; (iii) characterize types algae cultivation systems; (iv) challenges advantages phycoremediation.

Abstract. Coastal environments, in particular heavily populated semi-enclosed marginal seas and coasts like the Baltic Sea region, are strongly affected by human activities. A multitude of impacts, including climate change, affect different compartments environment, these effects interact with each other. As part Earth Assessment Reports (BEAR), we present an inventory discussion human-induced factors processes affecting environment their interrelations. Some naturally occurring modified activities (i.e. coastal processes, hypoxia, acidification, submarine groundwater discharges, marine ecosystems, non-indigenous species, land use cover), some completely agriculture, aquaculture, fisheries, river regulations, offshore wind farms, shipping, chemical contamination, dumped warfare agents, litter microplastics, tourism, management), they all interrelated to degrees. We a general description analysis state knowledge on Our main insight is that change has overarching, integrating impact other can be interpreted as background effect, which implications for factors. Impacts sphere roughly allocated anthropogenic drivers such food production, energy transport, industry economy. The findings from this available information interactions region largely transferred comparable world.
