AI Article Synopsis
- Haiti ranks lowest in the Western Hemisphere for access to improved water and sanitation, currently facing a significant cholera outbreak.
- An assessment in the Artibonite Department in 2012 revealed that only 42.3% of households use safe drinking water sources and many tested positive for harmful bacteria.
- The findings highlight the urgent need for investment in water and sanitation infrastructure, along with promoting household water treatment solutions to ensure safer water access.
Article Abstract
Haiti has the lowest improved water and sanitation coverage in the Western Hemisphere and is suffering from the largest cholera epidemic on record. In May of 2012, an assessment was conducted in rural areas of the Artibonite Department to describe the type and quality of water sources and determine knowledge, access, and use of household water treatment products to inform future programs. It was conducted after emergency response was scaled back but before longer-term water, sanitation, and hygiene activities were initiated. The household survey and source water quality analysis documented low access to safe water, with only 42.3% of households using an improved drinking water source. One-half (50.9%) of the improved water sources tested positive for Escherichia coli. Of households with water to test, 12.7% had positive chlorine residual. The assessment reinforces the identified need for major investments in safe water and sanitation infrastructure and the importance of household water treatment to improve access to safe water in the near term.

The rational design of molecules with the desired functionality presents a significant challenge in chemistry. Moreover, it is worth noting that making chemicals safe and sustainable is crucial to bringing them to the market. To address this, we propose a novel deep learning framework developed explicitly for inverse design of molecules with both functionality and biocompatibility.

Perfluorohexanoic acid (PFHxA) and perfluorobutanoic acid (PFBA) are widely used substitutes to perfluorooctanoic acid (PFOA). Whether these substitutes are less toxic than PFOA remains unclear owing to differences in the experimental methods, test organisms, and other experimental conditions in previous studies. The present study selected 0.

Silver, as the oldest antibacterial material, has been almost replaced by other alternatives for its insufficient activity or potential side-effects on the ecosystem due to the over-release of Ag ions (Ag). Herein, a facile and general strategy is developed to on-substrate fabricate silver coordination polymer nanowire arrays (Ag CPN) by simply immersing Ag-containing substrates into cationic surfactant solution at room temperature. Such a Ag CPN not only provides high-surface-area nano-biointerfaces for destroying microorganisms via physicomechanical interactions but also acts as a safe Ag reservoir, steadily releasing Ag at a relatively high but safe level (∼40 ppb, but lower than the safe level of 100 ppb).
