The microbiological quality of forest surface waters in the Greenwater River watershed was examined to investigate the influence of heavy motorized camping in an area with no sanitary facilities. Indicator densities increased during weekend human-use periods when compared to weekdays. Increases in indicator densities were also noted downstream from heavily used camping areas when compared to up...

Ice cream is the major dairy product that dominates interest of large segments of the population. As a result, its production and consumption are rapidly increasing. The microbiological quality of ice cream during retail marketing mainly depends on the contamination during the product handling as well as efficiency and sanitary conditions during frozen storage. Many food poisoning cases associa...

Regulatory Impact Analysis, which is recommended to regulatory departments, aims to improve regulatory quality by providing information about the costs and benefits of regulation as well as solutions to current issues to enhance the decision-making process. This article discusses the importance of Regulatory Impact Analysis in the context of the National Agency for Sanitary Surveillance perform...

n instrument for the automatic quantification of glycerol in grapes has been developed. We verify here that this analyte can be used as a benchmark of a serious disease affecting the grapevines, namely Botrytis cinerea. The core of the instrument is an amperometric biosensor consisting of a disposable screen printed electrode, generating the analytical signal thanks to a bi-enzymatic process in...

This study reports on a headspace gas chromatographic method (HS-GC) for the determination of formaldehyde in sanitary napkin samples. The method is based on the reaction of formaldehyde and sodium borohydride in a concentrated potassium carbonate solution (824 g/L), in which formaldehyde is quantitatively converted to methanol at 105°C in 45 min. The methanol from the conversion is determine...

There are various possibilities for the design of urban stormwater systems, using best management practices. Castro and Baptista (2004) have proposed a set of performance indicators, based social, environmental, sanitary and hydrologic aspects. During the validation process, a critical analysis of the indicators was done. The aim of this paper is to present the results of this analysis which is...
