Cumulative effect of foliar application of copper oxychloride on Pb content in black tea
Copper oxychloride was found as one of the sources of lead contamination in tea as this fungicide is being widely used in tea fields to control the blister blight disease. In India, there is no specification for this heavy metal in copper oxychloride formulations. Commercial brands of copper oxychloride were collected from market and analyzed for lead (Pb) an element of environmental concern. Results were compared with limits prescribed by Food and Agricultural Organization (FAO) of United Nations with a view that these results could be used for fixing limits of heavy metal impurities in national level for the copper oxychloride formulations. Field trials were initiated using the lead contaminated copper oxychloride and in combination with hexaconazole. The study indicates lead contaminated copper oxychloride is one of the sources for lead contamination in black tea. The accumulation of lead content in tea was positively correlated with the application of contaminated copper oxychloride formulations.
期刊介绍：
The Journal of Tea Science was established in August 1964, approved by the Publicity Department, CCCPC. Its title was inscribed by Zhu De, the chairman of CCCPC. It was discontinued during the Cultural Revolution in 1966, and it was reissued in August 1984, approved by the State Scientific and Technological Commission.Academicians Chen Zongmao and Liu Zhonghuaof the Chinese Academy of Engineering served as the directors of the editorial board. The Journal of Tea Science is managed by the China Association for Science and Technology,sponsored by the China Tea Science Society and the Tea Research Institute of the Chinese Academy of Agricultural Sciences, and edited and published by the editorial office of the Journal of Tea Science. It is the only one of Chinese core journals in the field of tea science that is included in the core library of the Chinese Science Citation Database.Its Domestic Unified Serial Number is CN 33-1115/S, its International Standard Serial Number is ISSN 1000-369X and its International publication name code is CODEN-CHKEF4. At present, the Journal of Tea Science is a bimonthly publication, published in the middle of the month, with a book size of 16.
