Sewage Sludges

Soil is a powerful and active absorber of many substances, assumes the pressure of industrial and municipal emissions and waste, and performs the important role of a buffer and a detoxicant. It accumulates heavy metals, pesticides, hydrocarbons and other chemical polluting substances and due to the soil absorbing complex (SAC) strongly captures and protects natural waters and the atmosphere from harm. Applying sewage sludges in our research will enable us to strengthen the capacity of SAC and to reduce the toxicity of heavy metals when they enter a reservoir via a drain from anthropogenically polluted territory.

Background: Phytonutrients in peach fruits have health promoting antioxidants against various chronic diseases. However, there is no extensive data to show the nutritional values of Local peach cultivars after post-harvest treatments. Objective: Mainly this study was objective to determine the effect of calcium carbide on nutritional value and quality of fruits of Pakistani peach cultivars. Methods: The peach fruits were collected from three different peach orchids of KPK and the fruits were divided into 4 groups while 5th group was collected from local fruit shop. Each experimental group was treated with different concentration of calcium carbide whereas control group was not treated. The peel and pulp samples were oven dried and ground to fine powder separately. The elemental compositions were determined using Particle Induced X-ray emission and Pelletron Tandem Accelerator. Result: Sixteen elements were identified in peach fruits and the elements were Al, P, S, Cl, K, Ca, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, and Se. In peel, concentration of some elements increased or decreased after treatment with CaC2 while in pulp the conc. of nearly all detected elements was increased in treated samples. We found significantly high amount of heavy metals traces including As, Se, Co, Si, and P in peach fruits treated with CaC2. Interestingly, the presence of trichomes in peach skin prevents the transfer of these heavy metals deep into the pulp which was also verified by the elemental profiling of nectarines. Conclusion: Conclusively, the artificial ripening with CaC2 changed the nutritional value of peach fruits that has higher health risks if consume with the peel. According to our best knowledge, this is the first report that highlights the effects of CaC2 which deteriorate the nutritional value of peach fruits in Pakistan.

Sessile Organisms

Coastal areas are known to receive significant anthropogenic inputs, mainly deriving from metropolitan areas, industries, and activities related to tourism. Among these inputs, some trace elements are listed as priority pollutants in the European Water Framework Directive, due to their ability to bioaccumulate in organisms. Many studies have been conducted on heavy metals (HMs) accumulation and on their possible effects on different edible marine species. While the most studied sessile organisms are bivalves, in the current review, we focus our attention on other sessile taxa (sponges, cnidarians, bryozoans, polychaetes, cirripeds, and tunicates), proposed as bioindicators in coastal shallow waters. Although their potential as bioindicator tools has been repeatedly highlighted in the literature, these organisms are still poorly investigated and considered for monitoring. In this context, we analyze the available literature about this topic, in order to summarize the current knowledge and identify possible applications of these organisms in a bioremediation scenario.

A mouse hepatocyte cell line selected for growth in 80 microM CdSO4 (Cdr80 cells) was used to test the role of metallothioneins in heavy metal detoxification. The cadmium-resistant (Cdr80) cells have double minute chromosomes carrying amplified copies of the metallothionein-I gene and accumulate ca. 20-fold more metallothionein-I mRNA than unselected cadmium-sensitive (Cds) cells after optimal Cd stimulation. As a consequence, the amount of Cd which inhibits DNA synthesis by 50% is ca. 7.5-fold higher in Cdr80 cells than in Cds cells. Cds and Cdr80 cells were compared in terms of their resistance to other heavy metals. The results indicate that although Zn, Cu, Hg, Ag, Co, Ni, and Bi induce metallothionein-I mRNA accumulation in both Cdr80 and Cds cells, the Cdr80 cells show increased resistance to only a subset of these metals (Zn, Cu, Hg, and Bi). This suggests that not all metals which induce metallothionein mRNA are detoxified by metallothionein and argues against autoregulation of metallothionein genes. Metallothionein-I mRNA is also induced by iodoacetate, suggesting that the regulatory molecule has sensitive sulfhydryl groups.
