Leaching Rate of Polychlorinated Biphenyls (PCBs) from Marine Paint Chips. [PDF]

open access: yesArch Environ Contam Toxicol, 2021
AbstractPolychlorinated biphenyls (PCBs) were added to certain marine vessel bottom paints as a plasticizer to improve the adhesion and durability of the paint. The most common PCB formulation used to amend such paints was Aroclor 1254. Fugitive Aroclor-containing paint chips generated from vessel maintenance and repair operations represent a potential

Rotating maize reduces the risk and rate of nitrate leaching

open access: goldEnvironmental Research Letters, 2021
There is a strong link between nitrate (NO _3 -N) leaching from fertilized annual crops and the rate of nitrogen (N) fertilizer input. However, this leaching-fertilizer relationship is poorly understood and the degree to which soil type, weather, and ...

Polluted soil leaching: unsaturated conditions and flow rate effects

open access: diamondEURASIAN JOURNAL OF SOIL SCIENCE (EJSS), 2017
In this study, soil samples are extracted from a polluted site at different depths. Soils texture and pollutant presence are different with depth. Preliminary analyzes showed pollution by heavy metals. To simulate soil leaching operation in static condition, a series of leaching tests are conducted in laboratory column under conditions of upflow ...
