Abandoned mine sites continue to present serious environmental hazards because the heavy metals associated with extractive waste are continuously released into the environment, where they threaten human life and the environment. Remediating and securing extractive waste are complex, lengthy and costly processes. Thus, in most European countries, a site is considered for intervention when it poses a risk to human health and the surrounding environment. As a consequence, risk analysis presents a viable decisional approach towards the management of extractive waste...

It is a matter of serious concern that the number of case reports pointing at a possible association between the clinical toxicity and the use of Ayurveda formulations is increasing significantly over the years in scientific medical literature. Though most of these cases are connected with the presence of heavy metals such as lead, mercury and arsenic in these formulations, there are also reports suggesting toxicity due to the presence of toxic chemicals of herbal origin. In the year 2008, the Government of India took an initiative of establishing the National Pharmacovigilance Programme for Ayurveda, Siddha and Unani drugs in a structured way...
