“…Chromated copper arsenate used as a wood preservative [53], could be probable reasons for the high Cr deposition in Site 6. Cr concentration was higher than the background value of 90 mg•kg −1 [47] [48] for all sites except Sites 9 and 10.…”

Freshwaters are not only used locally in many developing countries but they are often over exploited for domestic purposes, agriculture and disposal of industrial wastes which result in an overload of excess nutrients, harmful chemicals and heavy metals. Plant species together with sediments and water samples collected from eleven aquatic water bodies in the vicinity of industrial units in Kolkata were studied for their potential to uptake Pb, Cd and Cr under field conditions. Cd and Cr concentrations in the sediments were higher than background values considered to be toxic.Alternanthera philoxeroides and Eichhornia crassipes were the two invasive species present, with the former being more widely distributed. Among native plants, Ipomoea aquatica was the most abundant. Metal uptake in the plants differed among species, tissues and sites. Pb and Cd accumulation in root tissues for all plants in most sites suggested an exclusion strategy for metal tolerance. Since I. aquatica is widely consumed in many parts of SE Asia, its metal content should be checked before use since it was found to efficiently translocate both Pb and Cd from roots to shoots.The potential of A. philoxeroides as a metal excluder needs to be explored further since it translocates less to its shoots as compared to E. crassipes and I. aquatica.

“…Two examples are chromated copper arsenate (CCA), which is widely used in residential, commercial and industrial building, and pentachlorophenol, which is usually used for treating utility poles and cross arms (Hingston et al 2001;Schultz et al 2007). The environmental hazards associated with the use of both chromium and arsenic salts limit their future application.…”

“…At present, the use of traditional toxic wood preservatives is being questioned and their application is restricted (Hingston et al 2001;Ibach 2005;Townsend et al 2005). As alternatives to these preservatives, wood can be modified by nontoxic chemicals and/or by physical treatments (Hill 2006).…”

Mode of action of brown rot decay resistance in modified wood: a review

Chemically or physically modified wood materials have enhanced resistance to wood decay fungi. In contrast to treatments with traditional wood preservatives, where the resistance is caused mainly by the toxicity of the chemicals added, little is known about the mode of action of nontoxic wood modification methods. This study reviews established theories related to resistance in acetylated, furfurylated, dimethylol dihydroxyethyleneurea-treated, and thermally modified wood. The main conclusion is that only one theory provides a consistent explanation for the initial inhibition of brown rot degradation in modified wood, that is, moisture exclusion via the reduction of cell wall voids. Other proposed mechanisms, such as enzyme nonrecognition, micropore blocking, and reducing the number of free hydroxyl groups, may reduce the degradation rate when cell wall water uptake is no longer impeded.
