Background: A study on the migration characteristics of 238U, 210Po, 232Th and 40K within the soil to the wild plants in the Western Ghats were carried out. Materials and Methods: Concentrations of these radionuclides were measured in different depths of soil and from different species by employing gamma ray spectrometer and alpha counter. Results: The activity concentration of these r...

Background: Investigation on the natural radionuclides 238U, 232Th, 40K and natural fallout radionuclide 210Po in the prominent plants species of Western Ghats tropical forest near Kotagiri have been carried out as a part of baseline background radiation studies in the forest environment. Materials and Methods: The prominent plants species of the region Evodia roxburghiana and Eleaoca...

Air pollution is a common environmental problem. Planting trees can minimize the adverse effects of air pollution. Plants absorb and accumulate pollutants through stomata. Biochemical changes in leaves will appear as physiological response plants to that be known by calculating APTI (Air Pollution Tolerance Index) value. This study aimed analyze differences responses five tree species Taman Mar...

This article reports the deliverables of experimental study on production a completely renewable biofuel from Manilkara zapota fruit and seed oil. It was attempted to synthesis ethyl ester oil using bioethanol synthesized decayed fruit. Bioethanol produced through fermentation fruit, waste skin, pulp with Saccharomyces cerevisiae then distilled at 72°C. The yield noted as 10.45% (v/w). 95.09% p...

ABSTRACT: This study was conducted to establish the pattern and spatial associations of Amazon commercial tree groups. In a region extending across 2,000 ha in Tapajós National Forest (FNT), Pará, forest census conducted. The included trees perimeter at breast height (PBH), equal or greater than 158 cm Cartesian coordinates their bearings. Using Ripley’s K function, discerned, with 5 m radius b...
