In urban environments, particularly areas under reconstruction, metals, organic pollutants (OP), and microplastics (MP), are released in large amounts due to heavy traffic. Road runoff, a major transport route for pollutants, contributes significantly deteriorated water quality receiving waters. This study was conducted Gothenburg, Sweden, is unique because it simultaneously investigates the oc...

harvesting corn created annually a large amount of organic waste, which could be a suitable initial substrate for vermicomposting due to its high c/n ratio. the present study was aimed for recycling of corn residues and production of good quality vermicompost, after processing by eisenia fetida. the setup of experiments was conducted with 40, 60 and 80% of corn residue, compost, cow dung and pa...

In many urban situations, both the municipal sewage system and industrial wastewater treatment are inadequate. A municipal sewage network may be in place, but coverage is usually incomplete, and the level of treatment provided is inadequate. Even where reasonable treatment facilities exist, poor maintenance and operation often result in failure to meet design effluent levels. In such circumstan...

In this study, we evaluated the possible role of Ligia italica as a bioindicator for the monitoring of heavy metals pollution in the suppralittoral zone of marine rocky coasts. Between 2004 and 2011 specimens of L. italica were collected along the Eastern Sicilian coasts from sites known for their high pollution levels as they are near to an area where in September 2001 a refinery plant dischar...

he 1980s brought changing trends into the waste market with increased reclamation, T recycling and waste minimization efforts. Adapting proven tcchnologies has aided in moving these three forms of waste managcment forward. A t EncycleITexas, Inc. (ETI), the fundamental objcctive of recycling is to convert hazardous waste into products. Founded in 1988, ET1 recycles metalbearing waste streams to...

Heavy-metal sources in urban environments include automobile exhaust, fuel combustion, tires, road asphalt, weathering of building materials, and/or industrial activities. The presence heavy metals stormwaters constitutes a potential risk for water resources and aquatic life. Results from the present study demonstrated effectiveness two different lightweight aggregates (LWAs), Arlita Filtralite...

Contaminated runoff stormwater from urban environments carries several contaminants to water bodies, thereby affecting the health of living beings and ecological systems. Among all contaminants, heavy metals possess high toxicity impact quality. The management through green infrastructures composed by adequate materials can provide an excellent solution, simultaneously ensuring appropriate hydr...

Large tracts of abandoned urban land, resulting from the deindustrialization of metropolitan areas, are generating a renewed interest among city planners and community organizations envisioning the productive use of this land not only to produce fresh food but to effectively manage stormwater and mitigate the impact of urban heat islands. Healthy and productive soils are paramount to meet these...

Sedimentation is a widely used technique in structural best management practices to remove pollutants from stormwater. However, concerns have been expressed about the environmental impacts that may be exerted by the trapped pollutants. This study has concentrated on stormwater ponds and sedimentation tanks and reports on the accumulated metal concentrations (Cd, Cr, Ni, Pb, and Zn) and the asso...
