Abstract. The aqueous speciation of A1 was studied in acid forest soils in N.W. Spain. Aluminum concentrations were 10-70 pmol L-', with variable proportions of labile, nonlabile, and acid-soluble Al. Almost all the labile A1 was found complexed with F-, A13+ concentrations being low. The importance of organic matter was seen in the formation of Al-organic complexes in the solid soil fraction and the presence of aqueous alumino-organic complexes in superficial horizons (umbric epipedons) rich in organic matter.

The commonhold called "horizontal property" requires coexistence of neighbors within a building but this feature does not exclude the defense of personality rights, such as honor, privacy and data protection; anyway, some limits are derived from the legal regime. This article analyzes issues such as the placement of CCTV cameras, at the time of making a new Spanish Data Protection Act, according to General Data Protection Regulation (GDPR).
