Distribution and bioavailability of chromium in contaminated soils by tannery residuesDistribuição e biodisponibilidade de crómio em solos contaminados por resíduos de couro
(2009-01-01)
Samples of soil, water and sediment were collected and analyzed in order to evaluate chromium, contamination due to deposition of tannery residues onto soils under different management regimes. The results showed that soils ...
Effect of electroless nickel interlayer on the fatigue strength of chromium electroplated AISI 4340 steel
(Elsevier B.V., 2007-04-01)
Deposition of wear-resistant hard chromium plating leads to a decrease in the fatigue strength of the base material. Despite the effective protection against wear and corrosion, fatigue life and environmental requirements ...
Assessment of chromium contamination in the Monte Alegre stream: a case study
(Tecpar, 2011)
The aim of this work was to study the contamination by chromium in the sediments of the Monte Alegre stream and in the larvae of Odonata and the possible impact caused by them on the stream macroinvertebrates community. ...

The aim of this work was to study the contamination by chromium in the sediments of the Monte Alegre stream and in the larvae of Odonata and the possible impact caused by them on the stream macroinvertebrates community. ...
Evaluation of the genotoxic potential due to the action of an effluent contaminated with chromium, by the comet assay in CHO-K1 cultures
(2005-12-01)
The comet assay technique has been considered to be more efficient in the biomonitoring of aquatic environments that the micronucleus and sister chromatid exchange techniques. The comet assay has been used to determine ...
The significance and determination by image analysis of microcrack density in hard chromium plating
(2008-04-01)
It is well known that the microcrack density is a fundamental parameter in hard chromium electroplating. The chemical and mechanical properties of this coating are widely dependent on its microcrack density. In this paper ...
