Water sources classified as "improved" may not necessarily provide safe drinking water for householders. We analyzed data from Nepal Multiple Indicator Cluster Survey 2014 to explore the extent of fecal contamination of household drinking water. Fecal contamination was detected in 81.2% (95% confidence interval [CI]: 77.9-84.2) household drinking water from improved sources and 89.6% (95% CI: 80.4-94.7) in water samples from unimproved sources. In adjusted analysis, there was no difference in odds of fecal contamination of household drinking water between improved and unimproved sources. We observed significantly lower odds of fecal contamination of drinking water in households in higher wealth quintiles, where soap and water were available for handwashing and in households employing water treatment. The extent of contamination of drinking water as observed in this study highlights the huge amount of effort required to ensure the provision of safely managed water in Nepal by 2030 as aimed in sustainable development goals.

Social learning, learning from other individuals, has been demonstrated in many animals, including insects, but its detailed neural mechanisms remain virtually unknown. We showed that crickets (Gryllus bimaculatus) exhibit aversive social learning with a dead conspecific. When a learner cricket was trained to observe a dead cricket on a drinking apparatus, the learner avoided the odor of that apparatus thereafter.

Cadmium (Cd) is a highly toxic metal in human body, and therefore understanding the immunotoxicity of Cd is significant for public health. The aim of this study was to investigate the role of hematopoietic stem cells (HSC) in regulating the immunotoxicity of Cd. After exposure to 10 ppm Cd via drinking water for up to 9 months, C57BL/6 mice had a suppressed adaptive immune system at day 135 but had an enhanced adaptive immune system at day 270 during Cd exposure.

In addition to traditional organophosphate esters (tOPEs), emerging organophosphate esters (eOPEs) have increasingly been detected in the environment, but their risks remain unclear. This study detected 12 tOPEs and 7 eOPEs in surface water, sediment, and suspended particulate matter (SPM) samples from important aquatic habitats and drinking water sources in Yibin (YB), Yichang (YC), Shanghai (SH), and Poyang Lake (PY) within the Yangtze River basin. The total concentration of OPEs (ΣOPEs) in surface water, sediment, and SPM from these four regions were 22.
