Marine species (n=36) available in a supermarket of Cluj-Napoca city, Romania were collected and analyzed for the levels of heavy metals (Cr, Cu, Zn, Cd, Pb, Hg) and As, polychlorinated biphenyls (PCBs), and organochlorine pesticides (OCPs), such as dichlorodiphenyltrichloroethane (DDT) and analogous, hexachlorocyclohexanes (HCHs) and hexachlorobenzene (HCB). The collection included samples from twelve fish groups (sardine, tuna, herring, pangasius, marbled rockcod, hake, shrimp, pink shrimp, lo...

AbstractNon-pesticide persistent organic pollutants (POPs) under the Stockholm Convention include polychlorinated biphenyls (PCBs),polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDDs/PCDFs), polybrominated diphenyl ethers(PBDEs), polybromobiphenyls (PBBs) and perfluorooctane sulfonate (PFOS), which are industrial chemicals and/orunintentional byproducts that remain in the environment, bioaccumulate in human and animal tissue through the food chain, andhave adverse effects ...

AbstractWater recycling and reuse, answering the needs of creating cleaner water resources, need to be closely related with water resourcemanagement and technologies. Current municipal wastewater treatment plants are capable to control conventional pollutants(carbonaceous compounds, particulate matter, nutrients). Priority organic compounds, like polyaromatic hydrocarbons,polychlorinated biphenyls, endocrine disrupting chemicals, personal care products, pesticides etc., may escape the treatment ...

This paper deals with the relevant environmental issues concerning marine sediments contamination, for which there is the need for further development of sustainable remediation technologies. Among the in-situ remediation options, the reactive capping turns out to be an interesting approach. On the other hand, when the sediments must be dredged, the stabilization and solidification (S/S) treatments can represent an efficient and sustainable solution for the recovery of the materials, in the spir...

Printed circuit boards are the most important component of any electrical and electronic device. The average metal content in waste printed circuit boards is ~30-35% whereas the rest of the material is a non-metal fraction (NMF). Metals in the waste printed circuit boards are recycled for their value whereas the NMF is mostly sent to landfills or incinerators for disposal. The circuit board laminates contain flame retardant chemicals that pose potential hazards to the environment and to public h...
