Influence of dipping time on cracking during bending of hot dip galvanized coatings with Sn and Ti contents
Published 2013-04-01“…Hot-dip galvanizing is a classical process aimed to generate coatings on iron-based surfaces, used unchanged since 200 years: some chemical elements are added in the bath with different aims (e.g., Pb is really important for its fluidizing properties, sometimes replaced by Sn) but sometimes these elements are dangerous for human health (e.g. … Pb!). …”

Physicochemical, Major Anions and Heavy Metals in Surface Water and Groundwater at Pb – Zn Mining areas of Ebonyi State, Nigeria
Published 2018-08-01“…The variations for the heavy metals suggest that mining operation is responsible for the distribution and redistribution of chemical elements. The result of the Correlation analysis and principal component analysis ( R- Mode and Q-mode) applied to the data analysis show that Zn, Pb, Cd, Cu, and Cr heavy metals originated from similar sources but may have been influenced by mining operation, while Ni, and As are attributed to a geogenic source. …”

How to assess water quality change in temperate headwater catchments of western Europe under climate change: examples and perspectives
Published 2022-10-01“…From these examples, we highlight four challenges for research on the relationships between climate and water quality: (i) developing functional typologies of chemical elements, (ii) performing multi-temporal and multi-spatial analysis by aggregating data into water-cycle periods, (iii) decoupling effects of climate conditions and human activities by testing hypotheses using parsimonious models, and (iv) incorporating water quality and aquatic ecosystem health into integrated models. …”

Impact of the Application of Domestic Wastewater by Subsurface Drip Irrigation on the Soil Solution in Sugarcane Cultivation
Published 2019-01-01“…The agricultural use of domestic sewage is a viable alternative for recycling nutrients; however, there is concern regarding the impact of its use due to the concentration of chemical elements present in this type of effluent. The use of principal component analysis determines the existence or lack of anomalous samples and the relations between measured variables and their relative contribution among samples that help in monitoring the impact of the use of effluents on soil chemical components. …”
