Phytomanagement of a Lead-Polluted Shooting Range Using an Aromatic Plant Species and Its Effects on the Rhizosphere Bacterial Diversity and Essential Oil Production.

This field study aimed to assess the baseline conditions of a long-term shooting range in Argentina polluted with 428 mg kg lead (Pb) to evaluate the establishment and development of plants and address the efficacy of the phytomanagement strategy through: (i) element accumulation in plant tissues; (ii) rhizosphere bacterial diversity changes by Illumina Miseq™, and (iii) floral water and essential oil yield, composition, and element concentration by GC-MS and ICP. After one life cycle growing in the polluted sites, in the roots of plants, Pb concentration was between 195 and 304 mg kg Pb. Only a limited fraction of the Pb was translocated to the aerial parts.

Synthesis and bioactivity of new phosphorylated R,R'-substituted sulfoximines.

R,R'-disubstituted sulfoximines were phosphorylated with O,O-diethylchloro phosphate and phosphorothionate to obtain new organophosphorus compounds. After purification they were characterized by GC-MS and (1)H-NMR. The toxicity of the synthesized O,O-diethyl N-(R,R'-disubstituted sulfoximine) phosphoro-amidothionates was assayed on Musca domestica.
