Waterborne pathogens and related diseases are a major public health concern worldwide, not only by the morbidity and mortality that they cause, but by the high cost that represents their prevention and treatment. These diseases are directly related to environmental deterioration and pollution. Despite the continued efforts to maintain water safety, waterborne outbreaks are still reported global...

The nature and magnitude of endemic waterborne disease are not well characterized in the United States. Epidemiologic studies of various designs can provide an estimate of the waterborne attributable risk along with other types of information. Community drinking water systems frequently improve their operations and may change drinking water treatment and their major source of water. In the Unit...

In this paper, a wood coating based on waterborne polyurethane (WPU)/nano-cellulose crystalline (CNC)/Magnesium hydroxide (MH) was prepared. Efficient dispersion of MH in WPU presence 5 wt% CNCs observed by biological microscope leading to material with improved esthetic, thermal and fire-retardant properties mechanical performance. By thermogravimetric analysis (TG/DTG) comparison WPU, the max...

Emulsion polymerization of (meth)acrylic bio-based monomers is a promising method to obtain waterborne coatings with reduced carbon footprint. However, the high hydrophobicity some can hinder straightforward incorporation such in dispersions. In this work, we explore copolymerization isobornyl methacrylate (IBOMA) 2-octyl acrylate (2-OA) produce latexes >70 % bio-content suitable for coating ap...

Fungal physical, chemical and aesthetical deterioration can occur by microbial biofilms adhere to the surface, leading alterations on paints integrity. The sol–gel method affords various merits added with biocides be used control paint films biodeterioration. aim of present research was obtain an efficient antifungal protection waterborne using a coating silver nanoparticles synthesized green m...

The surface modified hydrophilic zinc sulfide nano powder was prepared by hydrothermal method, and the corresponding sulfide/polyurethane organic-inorganic composite transparent coating via in-situ polymerization. structure of ZnS Nanoparticles were characterized Infrared Spectroscopy, X-Ray Diffraction, Laser Particle Size Analyzer Scanning Electron Microscopy. optical properties measured Ultr...

The selection of the wood surface pre-treatment process prior to finishing for an optimal wood-coating relationship can be challenging, but has a great significance properties coated products. present study compares beech ( Fagus sylvatica L.) after mechanical (MT), physical (PT) and chemical (CT) treatment shows relationships pre-treated with original (O) diluted (D, 10% water addition) waterb...

Objectives. Rainfall and runoff have been implicated in site-specific waterborne disease outbreaks. Because upward trends in heavy precipitation in the United States are projected to increase with climate change, this study sought to quantify the relationship between precipitation and disease outbreaks. Methods. The US Environmental Protection Agency waterborne disease database, totaling 548 re...

Observational studies have assessed endemic waterborne risks in a number of countries. Time-series analyses associated increased water turbidity with increased gastroenteritis risks in several public water systems. Several cohort studies reported an increased risk of gastroenteritis in populations using certain public or individual water systems. Although several case-control studies found incr...
