Emission estimation and congener-specific characterization of polybrominated diphenyl ethers from various stationary and mobile sources

Here we show that combustion sources, including waste incinerators, metallurgical processes, power-heating systems and so on, are also important emitters of polybrominated diphenyl ethers (PBDEs) to the atmosphere. Geometric mean PBDE concentrations in the stack flue gases of the combustion sources ranged from 8.07 to 469 ng/Nm3. The sinter plants (24.7 mg/h), electric arc furnaces [...]

When is a soil remediated? Comparison of biopiled and windrowed soils contaminated with bunker-fuel in a full-scale trial

A six month field scale study was carried out to compare windrow turning and biopile techniques for the remediation of soil contaminated with bunker C fuel oil. End-point clean-up targets were defined by human risk assessment and ecotoxicological hazard assessment approaches. Replicate windrows and biopiles were amended with either nutrients and inocula, nutrients alone or [...]

Payments for ecosystem services: From local to global

Payment for Ecosystem Services (PES) is becoming increasingly popular as a way to manage ecosystems using economic incentives. The environmental economics approach to PES tries to force ecosystem services into the market model, with an emphasis on efficiency. The ecological economics approach, in contrast, seeks to adapt economic institutions to the physical characteristics of ecosystem [...]

The natural environment is valuable but not infinitely valuable

This article discusses the appeal to infinite value in environmental decision making. We argue that invoking infinite values as a means of faithfully representing the worth of certain parts of the natural environment is a mistake. Infinite values have a number of theoretical and practical problems associated with them. For example, we show that invoking [...]

Status and distribution of mangrove forests of the world using earth observation satellite data

“Our assessment shows, for the first time, the exact extent and distribution of mangrove forests of the world at 30 meters spatial resolution, the highest resolution ever,” said Dr Chandra Giri from USGS. “This reveals that 75% of the remaining forest is found in just 15 countries, out of which only ~6.9% is protected under [...]

Characterizing the diversity of coral reef habitats and fish communities found in a UNESCO World Heritage Site: The strategy developed for Lagoons of New Caledonia

Since 1972, the UNESCO “World Heritage Convention” offers an international canvas for conservation and management that targets areas of high cultural and environmental significance. To support the designation of areas within the 36.000 km2 of New Caledonia coral reefs and lagoons as a World Heritage Site, the natural value and diversity of the proposed zones [...]

Using very high resolution remote sensing for the management of coral reef fisheries: Review and perspectives

Coral reef fisheries are critical for food security and as a source of income in developing and developed countries, but they are collapsing in many areas. Following the emergence and routine availability of commercial very high spatial resolution (0.6–10 m) multispectral satellite images, we reviewed the use of these new high-quality remote sensing data and [...]
