The corrosion and biological behaviour of titanium alloys in the presence of human lymphoid cells and MC3T3-E1 osteoblasts.

Corrosion behaviour of biomedical alloys is generally determined in mineral electrolytes: unbuffered NaCl 0.9% (pH 7.4) or artificial saliva (pH 6.

[Analysis of HCH in a typical waste contaminated site].

Soil samples in contaminated site of a historical HCH plant were collected and the levels and the distribution of HCH were analyzed and studied. The highest level of SigmaHCH was 271.72 mg kg(-1).
