ANALISIS KANDUNGAN MERKURI (Hg) PADA LIMBAH HASIL PENGOLAHAN EMAS DI GUNUNG NONA DESA WAPSALIT PULAU BURU

The research had been done to analyze the mercury (Hg) content on tailing the result of gold processing at Nona Mountain Wapsalit Village Buru Island. The dry sample was prepared by putting it into the oven at 400C temperatures in two days and then the wet destruction done to the sample. The Tailing was analyzed by using SSA – Cold Steam to get to know about the mercury (Hg) content. The result showed that the average mercury (Hg) content at the location I was 721,43 ppm and at the location II was 344,88 ppm. Thus, the results showed that tailing concentration at the location I had average mercury (Hg) content higher than at the location I

Integrating computational methods to predict mutagenicity of aromatic azo compounds

Azo dyes have several industrial uses. However, these azo dyes and their degradation products showed mutagenicity, inducing damage in environmental and human systems. Computational methods are proposed as cheap and rapid alternatives to predict the toxicity of azo dyes. A benchmark dataset of Ames data for 354 azo dyes was employed to develop three classification strategies using knowledge-based methods and docking simulations. Results were compared and integrated with three models from the literature, developing a series of consensus strategies. The good results confirm the usefulness of in silico methods as a support for experimental methods to predict the mutagenicity of azo compounds
