متن کاملThe clastogenic potential of triazine herbicide combinations found in potable water supplies.
Pesticide contamination of drinking water supplies has increased over the past decade. A major concern is how exposure to combinations of low levels of pesticides, especially herbicides, could affect public health. Flow cytometric analysis was performed to determine the clastogenic potential of herbicide interaction on Chinese hamster ovary (CHO) cells. The cells were exposed to atrazine, simaz...

متن کاملDisinfection of Burkholderia pseudomallei in potable water.
The effect of chlorine, monochloramine and UV disinfection on the water-borne pathogen Burkholderia pseudomallei was assessed. Persistence of B. pseudomallei was verified by MPN involving a one-step recovery procedure. Chlorine proved the most effective disinfectant with a 99.99% reduction of a 10(6) CFU/mL pure bacterial culture followed by 99.9% reduction by monochloramine and 99% reduction b...
متن کاملModelling and control of potable water chlorination.
The Umgeni Water Wiggins water treatment plant feeds the southern areas of Durban in South Africa and has a maximum treatment capacity of about 350 Ml/d. Two interconnected reservoirs at this facility hold treated water before it enters the distribution network. Because of the variable demand, the reservoir levels and residence times undergo considerable variation. This has a strong influence o...
