Maritime pollution by chemical products occurs at much lower frequency than spills of oil, however the consequences of a chemical spill can be more wide-reaching than those of oil. While detection and characterization of hydrocarbons have been the subject of numerous studies, detection of other chemical products at sea using remote sensing has been little studied and is still an open subject of research...
In this paper we show that hyperspectral imaging systems are able to improve the detection and characterization Hazardous and Noxious Substances (HNS) in the case of marine pollution. We analysed nadir hyperspectral image acquisitions from 0.4 to 12µm corresponding to two different campaigns: (i) HNS release at the surface of a sea water pool; (ii) HNS release in the Mediterranean Sea under real conditions...
The benefits of using organic waste as fertilizer and soil amendment should be assessed together with the environmental impacts due to the possible presence of heavy metals (HMs). This study involved analysing major element and HM contents in raw and size-fractionated organic wastes (17 sewage sludges and composts) from developed and developing countries. The overall HM concentration pattern showed...
