BACKGROUND The New Zealand city of Rotorua sits on a geothermal field. However, little is known about the possible health impacts of the geothermal emissions. This was an ecological study that examined cancer incidence and morbidity data for Rotorua. METHODS Cancer registry and hospital discharge (morbidity) data were obtained for the decade 1981-1990. Standardized incidence ratios (SIR) were...

INTRODUCTION Arterial hypertension is the main independent risk factor for cardiovascular (CV) disease and death. It affects development and course of cerebrovascular insult (CVI) and chronic kidney disease (CKD). Balneotherapy with sulphide baths was administered to patients having stage I hypertension (BP values 140-159/90-99), with no arrhythmia or pronounced coronary disease. Baths also had...

We demonstrate that copper-zinc-tin-sulphide nanoplatelets can be directly grown onto a molybdenum-coated substrate using spray pyrolysis starting from a mixture of metal thiocarbamates precursors. The structure and phase purity of the nanoplatelets is discussed in detail.

Monthly samples of six fish farms from January 2010 to December 2010 in the northern Iran, Haraz River, were used to determine relationship between chemical parameters of main water, inlet and outlet and their effects on fish growth and production. Results revealed that concentration of nutrients in outlet was more than that of inlet of farms and statistical analysis showed that there were sig...

Graphene, a monolayer of graphite, has appeared as one of the most fascinating materials of today’s Material Science research. The properties of graphene (GR) with high electronic conductivity, extraordinary strength and interesting chemical characteristics make it suitable for many different applications. All these tremendous properties of GR are relevant at the nanoscale, hence, in a view to ...

The study aimed to determine the efficiency of a wastewater treatment plant and quality effluent discharged by into receiving water body (Okochiri River) in Eleme, Rivers State. lasted for four months. Wastewater samples were collected at various stages unit tested major parameter such as Biological Oxygen Demand (BOD), oil/grease, phenol, Dissolved (DO), Total Suspended Solids (TSS), sulphide....

Cobalt sulphide nanoparticles solely confined within the nanopores of a water-stable Zr-based MOF are synthesized by two-step approach.

Abstract Acid sulphate soil and sulphide-bearing sediments cause various challenges in construction projects land use planning, as well harmful environmental effects. Fine-grained sulphide were mainly formed coastal areas during the Litorina Sea water phase at approximately 7000 BP capital region of Finland, but not all these contain clay. In this study, material property variables related to d...
