Ozone-driven chemistry is a source of indoor secondary pollutants of potential health concern. This study investigates secondary air pollutants formed from reactions between constituents of household products and ozone. Gas-phase product emissions were introduced along with ozone at constant rates into a 198-L Teflon-lined reaction chamber. Gas-phase concentrations of reactive terpenoids and ox...

Methods of evaluating eye preparations from a human safety standpoint have remained somewhat obscure. Toxicology and predictive irritancy studies in animal models can be readily retrieved from the literature (1-4), but methods for human testing are not as available. The rabbit is the species of choice for the preliminary evaluation of potential ocular irritation from toiletties, cosmetics and h...

BACKGROUND Systematic reviews and a network meta-analysis show home safety education with or without the provision of safety equipment is effective in promoting poison prevention behaviours in households with children. This paper compares the cost-effectiveness of home safety interventions to promote poison prevention practices. METHODS A probabilistic decision-analytic model simulates health...

BACKGROUND Green approach in synthesizing metal nanoparticles has gain new interest from the researchers as metal nanoparticles were widely applied in medical equipment and household products. The use of plants in the synthesis of nanoparticles emerges as a cost effective and eco-friendly approach. A green synthetic route for the production of stable silver nanoparticles (Ag-NPs) by using aqueo...

To study the pattern of acute poisoning in the New Territories East of Hong Kong, 291 adult cases admitted to the Prince of Wales Hospital in 1989 were reviewed. The female-to-male ratio was 2.3 to 1 and the majority of patients (83%) were below the age of 40. The main poisons involved were hypnotics and sedatives (44.3%), household products (14.8%) and analgesics (10%). The poisoning was inten...

Background: In the UK and other developed countries the prevalence of asthma symptoms has increased in recent years. This is likely to be the result of increased exposure to environmental factors. A study was undertaken to investigate the association between maternal use of chemical based products in the prenatal period and patterns of wheeze in early childhood. Methods: In the population based...

Logistics performance management has received more attention by government and organizations in recent years as it becomes the critical success factor of the supply chain. The study of logistics performance management in this paper aims to analyze dimensions and relevant factors of logistics information system (LIS) usage that affects logistics performance management under uncertainty. A survey...

in India like many other countries in the world. While pesticide poisoning is common in India many other poisoning are emerging like alcohol, sedatives, antipsychotics, anti-depression, cardiovascular drugs, analgesic, antimicrobial, herbal and plant products, household materials, homeopathic medicines and illicit drugs. The toxic agents can enter body by injection, inhalation and through skin....

Chloromethylisothiazolinone (MCI) and methylisothiazolinone (MI) have been widely used as preservatives in cosmetics, household products and industrial products since the late 1970s. First cases of contact allergy to the MCI/MI combination were noted in 1980-1982 in Sweden. Then, a significant increase in the frequency of sensitization to these compounds was observed in many European centers. T...

Introduction Children do not react like adults when exposed to environmental chemicals because their organ systems and metabolic capabilities are not fully developed. Children eat, breathe, and drink more, relative to their body mass, than adults. Their exposures to environmental chemicals differ from that of adults due to child-specific behaviors, such as hand-to-mouth and object-to-mouth acti...
