Lake Pampulha, an impoundment that is a major tourist focus within the municipality of Belo Horizonte, Minas Gerais state, Brazil, provides an example of degradation of aquatic environments by disorganised urbanization. We evaluated the current recreational suitability of the lake using state government monitoring data with reference to Brazilian legislation and a water quality index for contact recreation in Brazilian freshwaters, considering E. Our results show that, despite investments in pollution control, the recreational water quality of Lake Pampulha remains very poor. Contact recreation was most limited by persistent cyanobacterial blooms, but also faecal contamination and low visual water clarity.

Dendrons of one to four generations were synthesized from the building block and in a final step coupled to the core molecule. The focal point of the dendrons was protected by a benzyl ester group and deprotected by catalytic hydrogenolysis. The esterifications were performed by conversion of the acid into the corresponding acid chloride and followed by reaction of the acid chloride with the hydroxyl groups in the presence of triethylamine and dimethylaminopyridine.
Molecular self-diffusion studies of first, second, third, and fourth generation dendrimers were performed, in chloroform, using pulsed-field spin echo 1 H NMR spectroscopy. The effective radii of the dendrimers were estimated from the diffusion coefficients by assuming a spherical geometry for all dendrimers. The radii obtained were 7. View Author Information.
