Exfoliated transition metal dichalcogenides (TMDs) such as WS2 and MoS2 have shown exciting potential for energy storage, catalysis and optoelectronics. So far, solution based methods for scalable production of few-layer TMDs usually involve the use of organic solvents or dangerous chemicals. Here, we report an eco-friendly method for facile synthesis of few-layer WS2 and MoS2 nanosheets using ...

The development of chemical means of detoxification of pesticide wastes and spills is an increasingly important endeavor for the pesticide industry. The objective of this paper is to review some of the chemical degradation methods for pesticide decontamination that exist today. I n presenting each method, less emphasis has been put on technical detail of the method and more emphasis has been pu...

The humidifier disinfectant disaster (HDD) was not a simple poisoning accident by biocides, but a singular disaster in history created by chemicals in household products. This disaster was a result of the failure of a system for the management of chemical and product safety. Since the management authority for chemical usage safety is different from those for chemical safety in products, many bl...

Synthetic nitro musks are fragrant chemicals found in household and personal care products. The use of these products leads to direct exposures via dermal absorption, as well as inhalation of contaminated dust and volatilized fragrances. Evidence also suggests that humans are exposed to low doses of these chemicals through oral absorption of contaminated liquids and foods. As these compounds ar...

The first standards for chemical protective clothing (CPC) emerged mid to late 1980's and have evolved since as most standards are revisited every 5 yr. Over the past years, we have also seen a strengthening of the chemical and worker protection legislation around the globe (various forms of REACH) but also protection of workers. The most prevalent standards originate under the auspices of the ...

We recently established a novel disease entity presented as progressive respiratory failure associated with the inhalation of humidifier disinfectants. In April 2011, we encountered a series of peripartum patients with complaints of respiratory distress of unknown etiology, which was an uncommon phenomenon. Accordingly, we created a multidisciplinary team comprising intensivists, radiologists, ...

The aim of this work was to design a solar water treatment plant for household purpose. Water purification is the process of eradicating detrimental chemicals, biological poisons, suspended solids and gases from contaminated water. In this work we have reported an investigation of compact filter which is cost effective for developing countries and ease of maintenance. We have arranged a solar w...

The Smiths are busy raising two preschool children and managing multiple responsibilities at home and at work. They juggle household chores and child care on evenings and weekends. Like most Canadians, they strive to provide a safe home environment for their children. Laundry products are stored on a high shelf with other household chemicals. One evening, while preparing to do the laundry, Mr S...

OBJECTIVE: The goal was to examine comprehensively the patterns and trends of household cleaning product-related injuries among children treated in US emergency departments. METHODS: Through use of the National Electronic Injury Surveillance System database, cases of unintentional, nonfatal, household cleaning product-related injuries were selected by using product codes for drain cleaners, amm...
