Electronic waste (e-waste) generation is one of the major emerging problems of the modern era and requires consideration at the global, national and local levels. Moradabad, Uttar Pradesh, is one of the biggest hubs of e-waste recycling in India, where almost 50% of printed circuit boards (PCBs) waste of the country is being handled with the engagement of more than 50,000 people.
Black ash of PCBs is overtly dumped after carrying out recycling processes in the vicinity. The dumping is affecting the aquatic and terrestrial ecosystems of the vicinity due to this black powder ash. Analysis of ewaste black ash sample was carried out for metal content using ICP-OES. A significant amount of lead, copper, barium, tin, aluminium, silica, etc. was found in the e-waste black powder, which indicates the potential utilization of e-waste black powder in many applications. Hence there is an immediate need of an environment-friendly technology for e-waste recycling and to safeguard the environment.

India does not have a clear stand on the release and consumption of genetically modified crops (food). The only approved crop is Bt-cotton, which has put India on the global map as a cotton exporting country. Even so, Bt-brinjal is under moratorium and GM mustard is prevented from undergoing commercial trial. All these decisions are not based on sound scientific principles. Activism against has successfully prevented exploitation of a powerful technology that can contribute to India’s food and nutrition security. This article attempts to give a balanced perspective of genetic modification technology as one of the serious options to be considered on case to case basis. Ambivalence will seriously affect India’s food security in the future.Keywords

Chemistry is omnipresent in nuclear energy programmes all over the world. From the isolation and fabrication of fuel to the development of non-fuel materials and important nuclear processes, chemistry has played a crucial role. This article outlines the remarkable contribution that chemistry has made to the development of India’s nuclear science programme. After a general introduction that deals with the inception and diversification of chemistry in the Department of Atomic Energy and some initial milestone achievements, a few notable contributions at BARC and IGCAR have been discussed in detail. These include the contribution of chemistry towards the front-end and back-end of the nuclear fuel cycle, nuclear safety, radiation chemistry and chemical innovations catering to the needs of society. Each sub-section also includes possible future developments in the fields necessary for a sustainable nuclear energy programme.Full Text
