Calitatea bacteriologică a apelor îmbuteliate

Abstract

Drinking water may be contaminated by a range of chemical, microbial, and physical hazards that could pose risks to health if they are present at high levels. Examples of chemical hazards include lead, arsenic, and benzene. Microbial hazards include bacteria, viruses, and parasites, such as Vibrio cholerae, hepatitis A virus, and Cryptosporidium parvum, respectively. That is why bottled water is preferred instead of tap water. This study tried to evaluate the bacteriological quality of water in 100 bottles. 27% of the water samples were bacteriologically contaminated with flora developed at 220C and 370C and total coliforms. In one case the presence of Escherichia coli was identified and in one case the presence of Pseudomonas Aeruginosa was identified.
