bioMerieux, Inc., has recently introduced plastic bottles to replace glass bottles for use in the BacT/ALERT blood culture system. We compared the performance of the plastic to the glass bottles in a large clinical evaluation. Two blood cultures were collected from each patient, one using glass FA (aerobic) and FN (anaerobic) bottles and one using plastic FA and FN bottles. Of the 4,040 sets of...
Due to the rapid industrialization taking place globally, the problems generated are acute shortage of construction material and increasing in productivity of wastes. The production and consumption of plastic and the rate at which solid plastic waste (SPW) are created have increased considerably. Plastics constitute 12.3% of total waste produced most of which is from discarded water bottles. Th...
Polyvinylchloride (PVC) resins are widely used in industry. Asthma due to the thermal degradation products of PVC are well documented. In this first case of occupational asthma due to unheated PVC resin dust the patient was exposed to PVC resin dust during the mixing of chemicals used for making plastic seals for bottle caps.
Bisphenol A (BPA) is used in the production of plastic but has oestrogenic activity. Therefore, BPA substitutes, such as fluorene-9-bisphenol (BHPF), have been introduced for the production of so-called 'BPA-free' plastics. Here we show that BHPF is released from commercial 'BPA-free' plastic bottles into drinking water and has anti-oestrogenic effects in mice. We demonstrate that BHPF has anti...
Due to its chemical inertness and physical properties PET is particularly suitable for food packaging applications, especially for drinking water. More bottled water is consumed than other bottled beverages. This article is a survey and toxicological investigation of chemical compounds, which are able to diffuse from PET bottles to water. The exact detailed chemical composition of plastic mater...
Despite the large and growing literature on microplastics in the ocean, little information exists on microplastics in freshwater systems. This study is the first to evaluate the abundance, distribution, and composition of pelagic microplastic pollution in a large, remote, mountain lake. We quantified pelagic microplastics and shoreline anthropogenic debris in Lake Hovsgol, Mongolia. With an ave...
This paper deals with the status of solid waste pollution in touristic spots of North coastal Andhra Pradesh. Case studies of Eco tourism, cultural tourism and pilgrim tourism are elaborately discussed and the study is based on both primary and secondary data. Data collection includes field collection of solid waste, semi structured interviews and observation of tourists. Results indicate gener...
OBJECTIVE To determine urinary fluoride levels in school children in a non-fluoridated area in Trinidad and Tobago. METHOD Morning urine samples were requested from 750 children aged 5 to 14 years, attending a primary school in the area of St Joseph, north west Trinidad. Urine was collected at home and brought to school in labelled plastic bottles. Urinary fluoride concentration (ppm) was mea...
