The impact of fertilizers on the uptake of manganese in Cherry Belle radish plants: implications for human health.

Miracle-Gro Singles, Miracle-Gro Shake and Feed, and Vigoro fertilizers are associated with net loss/enhancement of Mn, up to an order of magnitude when referenced to controls in soil, radish vegetables, and radish leaves; Mn enhancements are a factor of 4 to 65 below the daily required intake for humans (2-5.5 mg/day). Manganese levels were measured by atomic absorption spectrometry (AAS).

Reactions of three halogenated organophosphorus flame retardants with reduced sulfur species.

Tris(haloalkyl)phosphates (THAPs) are among the most widely used flame retardants in the U.S. They have been identified as one of the most frequently detected contaminants in U.

Reaction of tris(2-chloroethyl)phosphate with reduced sulfur species.

Tris(2-chloroethyl)phosphates (TCEP) is a widely used flame retardant in the US. It has recently been identified as one of the most frequently detected contaminants in US streams. This contaminant is of toxicological concern in sensitive coastal ecosystems such as estuaries and salt marshes.
