Degradação do pesticida Padron® por processos fotoquímicos utilizando luz artificial e solar [PDF]

Química Nova, 2007
Destruction of Padron® (dye and picloram) was evaluated using a photoreactor and a solar reactor. Photolysis was observed using only a germicide lamp (GL). Black light (BL) and H2O2 (172 mmol L -1) promoted a conversion of 49% and 6% of dye and picloram, respectively.

Environmental Performance Drivers: A Political Cost Approach

Business Strategy and the Environment, EarlyView.
ABSTRACT We contribute to the business strategy and the environment literature by examining the effect of political cost pressures on corporate environmental performance in the context of United Kingdom‐listed firms. Drawing on a sample of non‐financial firms from the FTSE All‐Share Index over a period of 10 years (2013–2022), we construct novel ...

Integrated and closed‐loop biorefinery strategies for efficient waste valorization and biofuel production

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Advancements in biofuel production technologies are essential for reducing global dependence on fossil fuels and addressing their overexploitation. Many valuable components of biomass, such as cellulose, hemicellulose, and lignin, remain underused in traditional biorefineries, which typically rely on a single feedstock to produce a primary ...

Electrified rhythms: How hydropower infrastructure transforms hydrosocial relations of riverine communities in the Lower Sogamoso River, Colombia

People and Nature, EarlyView.
Abstract Hydropower dams regulate water flows for millions of downstream inhabitants worldwide, altering water availability. Under a changing climate, flow control is often framed technically and politically as being essential for reducing drought and flood risks. However, it can also disrupt ecological flows, impact livelihoods and erode environmental
