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

255 LEACHING FRACTION, FERTIGATION RATE AND PHOSPHORUS LEACHING FROM POTTED GERANIUM [PDF]
HortScience, 1994 Single-pinched `Yours Truly' geranium (Pelargonium × hortorum) were greenhouse grown in 15-cm diameter pots. They received constant liquid fertigation with a modified Hoagland solution #1 at 0.25, 0.5, 1.0, and 1.5 strength. The 1.0 strength Hoagland solution contained 210 mg/L NO3-N and 31 mg/L P. Leaching fractions (LFs) were 0, 0.2 and 0.4.
