Limestone beds of the Late Cretaceous Abiod formation (Campanian-Maastrichtian system) are fundamentally important for the economic growth of the raw material sector in Tunisia. However, little attention has been paid to the detailed physical and chemical properties of the Abiod limestone. Nine limestone samples collected from the Abiod formation outcropping in the areas of Bizerte, Gafsa and Gabes, Tunisia, as well as their separated clay fractions, were characterized using different techniques, such as XRF, XRD, FTIR and TG/DTA. XRF showed the chemical composition of the limestone in which calcium carbonate was the main constituent, and silica, iron and magnesium were the impurities. XRD also confirmed the presence of small amounts of clay minerals and quartz along with sharp peaks of calcite. FTIR spectra indicated that the limestone was mainly composed of CaCO 3 in the form of calcite, as identified by its main characteristic absorption bands. These data were in agreement with XRD and XRF analysis data. The TG/DTA curves of the limestone samples, showing a close similarity to that of pure calcium carbonate, exhibited an endothermic peak between 600 and 760°C, with the maximum near 750°C. Moreover, FTIR spectra of clay fraction samples indicated high silica content in some samples.Especially the samples SD1 and SD2 collected in the northern area showed higher amounts of silica compared with those of AS1, AS2, CHB, ZNC, SND, MKM and GBS collected from southern districts. However, among the latter seven samples, one could recognize two groups based on the clay mineral investigations: (1) limestone with minor amounts of smectite and mixed layer minerals of smectite/ illite (AS1 and 2, CHB, ZNC, SND and GBS) and (2) limestone with smectite, kaolinite and apatite (SND and MKM). Differences in these mineralogical and chemical characteristics should be considered when limestone from the Abiod formation is utilized as a medium for heavy metal removal from wastewater.

“…Those wastes dumped on land usually alter the landscape, where the wastes are placed as overburden, and can greatly reduce surface water percolation into the ground. Moreover, they can increase the alkalinity of a soil and reduce its fertility, making the soil unsuitable for cultivation (Montero et al 2009).…”

Abstract. Trinitrotoluene (TNT), a commonly used explosive for military and industrial applications, can cause serious environmental pollution. 28-day laboratory pot experiment was carried out applying bioaugmentation using laboratory selected bacterial strains as inoculum, biostimulation with molasses and cabbage leaf extract, and phytoremediation using rye and blue fenugreek to study the effect of these treatments on TNT removal and changes in soil microbial community responsible for contaminant degradation. Chemical analyses revealed significant decreases in TNT concentrations, including reduction of some of the TNT to its amino derivates during the 28-day tests. The combination of bioaugmentation-biostimulation approach coupled with rye cultivation had the most profound effect on TNT degradation. Although plants enhanced the total microbial community abundance, blue fenugreek cultivation did not significantly affect the TNT degradation rate. The results from molecular analyses suggested the survival and elevation of the introduced bacterial strains throughout the experiment. Keywords: TNT, bioaugmentation, biostimulation, phytoremediation, microbial community.

“…De fato, existe extensa literatura [9][10][11][12][13] relacionada à caracterização e uso de resíduos sólidos provenientes da indústria de rochas ornamentais em materiais para a área. No entanto, estes trabalhos, via de regra, utilizam o resíduo de rocha ornamental de um único tanque de decantação, ou seja, sem a separação dos resíduos das diferentes etapas do processo de beneficiamento.…”

RESUMOO Brasil está entre os seis maiores responsáveis pela produção mundial de rochas ornamentais, sendo o centro produtor mais rico em granito. O setor de rochas ornamentais gera durante os processos de corte e beneficiamento enormes quantidades de resíduos sólidos poluentes, de tal modo que as quantidades de tais resíduos são esperadas para aumentar cada vez mais. O estado do Espírito Santo é o maior produtor e exportador nacional de rochas ornamentais e, nos processos de corte e beneficiamento são geradas grandes quantidades de resíduos sólidos que precisam ser reaproveitados, do contrário podem causar danos de difícil remediação ao meio ambiente. Dependendo do tipo de rocha e do tipo de processo de corte e beneficiamento, resíduos com distintas características podem ser gerados. Neste contexto, o presente trabalho objetiva caracterizar quatro resíduos de rochas ornamentais gerados em distintos processos de corte e beneficiamento denominados de resíduos granalha, dimantado, levigação e polimento. As amostras dos resíduos de rochas ornamentais foram caracterizadas em termos de composição química, morfologia, distribuição de tamanho das partículas, massa específica real e análise termogravimétrica (ATG/DTG). Os resultados experimentais indicaram que os resí-duos estudados apresentam diferentes características químicas e físicas. Os resíduos levigado, polimento e granalha são ricos em óxidos fundentes (K 2 O, CaO e Fe 2 O 3 ), enquanto que o resíduo diamantado é rico em SiO 2 . Os resíduos também apresentam distintos comportamentos granulométrico e térmico. Palavras-chave:Resíduo de rocha ornamental, caracterização, reciclagem. ABSTRACTBrazil is among the top six worldwide responsible by the production of ornamental rocks, being the richest production center in granite. The sector of ornamental rocks generates during the cutting and beneficiation processes huge amounts of pollutants solid waste, in such way that the amounts of such solid wastes are expected to increase more and more. The Espírito Santo state is the largest national producer and exporter of ornamental rocks. In cutting and beneficiation processes of ornamental rocks huge amounts of solid wastes that need to be reused are generated, otherwise they cause damage of difficult remediation to the environment. Depending on the type of rock and the type of cutting and beneficiation process, wastes with different characteristics can be generated. In this context, this work aims to characterize four ornamental rocks wastes generated in different cutting and beneficiation processes denominated as shot waste, diamond waste, levigation waste, and polishing waste. The ornamental rock wastes samples were characterized in terms of chemical composition, morphology, particle size distribution, real specific mass, and thermal analysis (TGA/TGD). The experimental results indicated that the studied ornamental rock wastes presented different chemical and physical characteristics. The levigation, polishing, and shot wastes are rich in K 2 O, CaO and Fe 2 O 3 , while t...
