Toxic heavy metals are harmful pollutants increasingly discharged in the environment by natural and anthropogenic means. Due to its widespread use in industrial processes, chromium presents a significant impact on the surface waters and ecosystem services. Because
The tetracycline family of antibiotics are widely used for human therapy and animal feed. However, tetracycline (TC) is considered a contaminant of emerging concern in the environment due to its presence in wastewater effluents, surface waters and
In Canada, endocrine disruptors are a very topical issue in wastewater effluent quality. We define endocrine disruptors as chemicals that can interfere with the endocrine or hormone systems in wildlife and humans. Results can vary from different

In recent years, engineered nanoparticles (ENPs) have been incorporated into a variety of consumer products such as technology, cosmetics, pharmaceuticals and clothing to name but a few. ENPs can be defined as intentionally created particles sized 1-100
Flocculation using starch-based flocculants: An efficient pretreatment for purification of the textile dyeing secondary wastewater
China is a major textile manufacturer in the world; as a result, large quantities of dyeing effluents are generated every year in the country. Textile dyeing effluents are distinguished by high levels of chrominance, chemical oxygen demand,
An hybrid solid system for the degradation of persistent pollutants was realized by mixing titanium dioxide, silica and an enzyme extracted from soybean hulls. Removal of organic pollutants from urban and industrial wastewaters is one of the
Impact of selected NSAIDs on performances, microbial activity and microbial community in sequencing batch reactors
The non – steroidal anti – inflammatory drugs ( NSAIDs ) are the most commonly used drugs worldwide. Among them, diclofenac ( DCF ), ibuprofen (IBP) and naproxen (NPX) were frequently detected in the environment as the
