One of the crucial problems for wooden garden furniture is fading with effect UV rays. The color changes as a result weathering have affected usage furniture. In this study, waterborne acrylic coatings containing bark extracts were evaluated an environment-friendly wood surface preservative to improve service life in outdoor conditions. For purpose, produced using from 10 tree species applied o...

The easy leaching of boron from wood preservation formulations has limited the use of this highly active fungicide. The recently discovered adduct with flavonoids allows boron to be retained for longer periods of time within wood and consequently to extend its life. Two different leaching treatments were compared, and the fungal and termite decay were examined. The biological tests showed extre...

the entomopathogenic fungus metarhizium anisopliae (metschnikoff) sorokin, causal agent of green muscardine of insects, is an important fungus in biological control of pests. no reports exist on the impact of this fungus on microcerotermes diversus silvestri (iso.: termitidae) in the world. the present research evaluated efficacy of strain demi001, from saravan, iran, against m. diversus. the t...

Arsenic-contaminated drinking water presents a serious health hazard in certain geographic locations around the world. Chromated copper arsenate, a pesticide and preservative that was used to pressure treat residential lumber in the United States beginning in the 1940s and was banned by the Environmental Protection Agency in 2003, poses a potential source of arsenic exposure and toxicity. In th...

Selection of the best method for preserving structural timbers in the marine environmentrequires an assessment of the relative toxicity of preservation methods. Creosote has beenidentified as toxic to herring embryos in a laboratory experiment where the LC50 for hatchingsuccess was reported to be 50 ppb (Vines et al 2000). In the current study, Pacific herringembryos were expose...

The use of scanning electron microscopy in conjuction with energy dispersion analysis of X rays is presented as a technique in a novel application to in situ studies of cellular elemental composition. The method has been applied, in the example of its use reported here, to examining the effects of copper-chromearsenic wood preservative on growth and element uptake of selected bacteria in agar c...

Pentachlorophenol (CASRN 87-86-5) is a wide spectrum biocide that has been used extensively, primarily as a fungicidal wood preservative, in the United States and elsewhere since the mid1930s. In 1987 the U.S. EPA restricted the use of pentachlorophenol to non-residential use, primarily to the treatment and preservation of utility poles and cross arms, railroad ties, wharf pilings, and laminate...

Sodium Tetraborate, also known as Borax, is a chemical compound which derivative of metal boron gas (B), used an antifungal compound, wood preservative, and antiseptic in cosmetics. The use Borax preservative food has been banned by the government. purpose this study was to help remove levels borax found meatball bulbs. Sampling determined Balongbendo District, Sidoarjo Regency. Analysis conten...

The purpose of this investigation was to assess the potential of Scots pine (Pinus sylvestris L.) bark and knot extractives to function as preservative chemicals. Scots pine was chosen to due to its importance in Finland; bark and knots were chosen due to their high extractives content and lack of industrial applications. The bark and knots of Scots pine were extracted with acetone and the extr...
