Polycyclic aromatic hydrocarbons (PAHs) and heavy metals contribute to pollutants in aquaculture facilities and thus need to be further investigated. Besides, there is little information regarding PAHs and heavy metals in the tissues of cultured fish, and the risks associated to consumption. In this review, emphasis has been made on the detection of PAHs and heavy metals in cultured fish specie...

This paper attempts to determine whether conditions amenable to successful selective interventions to capture cross-industry externalities are likely to be fulfilled in practice. Three criteria are proposed for good candidates for industrial promotion: that they have strong interindustry links to the rest of the economy, that they lead the rest of the economy in a causal sense, and that they be...

in petrochemical industry, the production of polyvinyl chloride (pvc) is accompanied by formation of heavy end wastes which consist of a mixture of di and multichloro compounds as kind of materials which are generated in ethylene dichloride (edc) purifcation. a high quantity of chloro compounds found in the heavy end waste allows it to be polymerized with alkaline polysulfdes to form polysulfde...

Heavy metal wastewater poses a threat to human life and causes significant environmental problems. Bioremediation provides a sustainable waste management technique that uses organisms to remove heavy metals from contaminated water through a variety of different processes. Biosorption involves the use of biomass, such as plant extracts and microorganisms (bacteria, fungi, algae, yeast), and repr...
