the adsorption properties and mechanics of selected endocrine disrupting compounds; 17 β-estradiol, 17 α – ethinylestradiol and bisphenol a on locally available black tea leaves waste and granular activated carbon were investigated. the results obtained indicated that the kinetics of adsorption were ph, adsorbent dose, contact time and temperature dependent with equilibrium being reached at 20 ...

in this study, the effects of different types of hand plucking were studied on green leaf yield and black tea quality. bud and a leaf, bud and two leaves, bud and three leaves and bud and four leaves were the types of hand plucking. plucking was down on chine’s hybrid tea and clone 100 in fuman tea research station. shoots were plucked in flashing period regularly during three years. green leaf...

Dengue mosquitoes are evolving into a broader global public health menace, with relentless outbreaks and the rise in number of Zika virus disease cases as reminders of the continued hazard associated with Aedes vectors. The use of chemical insecticides-the principal strategy against mosquito vectors-has been greatly impeded due to the development of insecticide resistance and the shrinking spec...

Background: The presence of lead in natural waters has become an important issue around the world. Lead has been identified as a highly toxic metal that can cause severe environmental and public health problems and its decontamination is of utmost importance. The aim of this work was to evaluate the adsorption of lead (Pb(II)) on waste tea leaves as a cheap purification method. Methods: In thi...

In this study, the possibility of using tea production waste as a new casing material in mushroom (Agaricus bisporus) cultivation was investigated. Some physical and chemical characteristics of tea waste, fermented tea waste and a mixture of tea waste with peat were compared with that of peat casing, as were their effects on yield. The highest yield was obtained from peat casing. Using tea prod...

Plant growth promoting ability of Bacillus megaterium (TRS-4), isolated from rhizosphere of tea bushes, was tested on 5 varieties of teaTV-18, TV-23, TV-25, TV-26 and T-17/1/154 in the experimental field and in potted condition. An increase in height, emergence of new leaves, branches and increase in leaf numbers as well as increase in leaf dry mass was observed following application of the bac...
