The authors conduct an integrated survey of Antimicrobial Resistant Organisms (AMR) in drinking water, wastewater and surface water in three settings in Bangladesh: rural households, rural poultry farms, and urban food markets. Results show that untreated water discharged from rural households, poul...try farms and urban markets are major contributors to surface water pollution and antibiotic resistant bacteria genes, calling for increased surveillance and monitoring.

Guidance has been updated on a number of chemicals: asbestos, bentazone, chromium, iodine, manganese, microcystins, nickel, silver, tetrachloroethene and trichloroethene. Guidance has also been added for chemicals not previously assessed in the Guidelines: anatoxin-a and analogues, cylindrospermopsi...ns and saxitoxins. The new guidance on organotins has replaced the prior guidance focused on dialkyltins. With these updates, the guideline values for tetrachloroethene and trichloroethene have been revised while new guideline values for cylindrospermopsins, manganese, microcystins, and saxitoxins have been established .
Updated information on cyanobacteria has been included, introducing an alert level framework for early-warning and to guide short-term management responses. Guidance has also been updated in the sections on adequacy of water supply, climate change, emergencies, food production and processing, and radiological aspects, particularly on managing radionuclides when exceeding WHO screening values and guidance levels.
