Hazardous enrichment of toxic elements in soils and olives in the urban zone of Lavrio, Greece, a legacy, millennia-old silver/lead mining area and related health risk assessment
(2022)Lavrio is a Greek town with several abandoned Ag/Pb mines. In this study, 19 potentially toxic elements (PTEs) were measured in soil, weeds, and olives. Levels of seven of the studied PTEs in soil were highly elevated: Zn ... -
Hazardous toxic metal(loid)s in top- and deep-soils during the transformation of aquaculture ponds restored to farmland
(2022)The pollution risks due to the soil migration of toxic metal(loid)s (TMs) are a greatly hazard to ecological environment as well as animal and human health. Previous studies have primarily focused on surface contamination ... -
Human health risk via soil ingestion of potentially toxic elements and remediation potential of native plants near an abandoned mine spoil in Ghana
(2021)Integrated studies about potentially toxic elements (PTEs) in sites near gold mining spoils, their contamination and human health risk, as well as remediation potential of native plants are limited. Therefore, our aim was ... -
Implementation of hazard analysis critical control point (HACCP) system to the alcoholic beverages industry
(2001)Alcoholic beverages (fermented or not) have been consumed for more than three thousand years and, generally, they have been considered safe because of their alcohol content. However, in recent years adulteration (i.e., use ... -
