Out of Plumb: When Water Treatment Causes Lead Contamination

Out of Plumb: When Water Treatment Causes Lead Contamination

Unsealed tubewells lead to increased fecal contamination of drinking water.

Bangladesh is underlain by shallow aquifers in which millions of drinking water wells are emplaced without annular seals. Fecal contamination has been widely detected in private tubewells. To evaluate the impact of well construction on microbial water quality 35 private tubewells (11 with intact cement platforms, 19 without) and 17 monitoring wells (11 with the annulus sealed with cement, six u...

Microbial Contamination of Staff’s Hand while Going out of Hospital

Abstract Background and Objective: Cross-transmission of microorganisms by the hands of health care workers is considered as a main transmission route of nosocomial infections. The aim of this study was to investigate the microbial contamination of health-care worker’s hands while going out of hospital. Material and Methods: Wearing the sterile glove with liquid culture, we obtained 100 Sam...

Increased water contamination and grow-out Pekin duck mortality when raised with water troughs compared to pin-metered water lines using a United States management system

Controversy has developed as to whether or not pin-metered water lines or water troughs are more appropriate for Pekin ducks. We hypothesized that water troughs would show improved duck body conditions and environmental quality compared to pin-metered water lines. To test this hypothesis, we housed ducks in 2 barns, one with water lines and one with water troughs. Water troughs were constructed...

Cadmium contamination of drinking water and its treatment using biological chelators

Background: Cadmium (Cd) is an extremely toxic metal and environmental exposure to Cd has been particularly problematic in the world. Oral exposure to Cd may result in adverse effects on a number of tissues, the immune system, and the cardiovascular system. Compounds containing Cd are also carcinogenic. The presence of Cd in drinking water resources in the southeastern region of Rafsanjan plain...
