Background. The fea­sibil­ity of the use of ­plants to lim­it the ­spread of pes­ti­cides ­released ­from inap­pro­pri­ate stor­age facil­ities was ana­lyzed ­through the ­case-­study of the selec­tion of ­plant spe­cies ­best suit­ed for tol­er­ance and ­uptake of pes­ti­cides ­from ­water and ­soil ­near the ­resort vil­lage of Niedzwiady, ­where a leak­ing ­tomb con­tain­ing xen­o­bi­o­tics is sit­u­at­ed. The leak­age is pos­ing ­risks of ­heavy con­tam­i­na­tion of under­ground ­water and, con­se­quent­ly, to the super­fi­cial ­water ­used in the ­area for drink­ing and for agri­cul­tu­ral ­uses. The ­extent of the prob­lem, ­which ­affects a ­very ­large num­ber of ­sites ­with dif­fer­ent con­tam­i­na­tion ­issues, ­calls for the devel­op­ment of ­fast, eco­nom­ic, and reli­able meth­ods for tol­er­ant ­plant selec­tion.
Materials and meth­ods. The screen­ing of ­plant spe­cies suit­able for phy­tor­e­me­di­a­tion was ­approached ­through stud­ies at ­four dif­fer­ent lev­els: ­plant tis­sue cul­ture, ­small-­scale experi­ments, in ­situ ­pilot-­scale reme­di­a­tion, and the plan­ning of ­full-­scale pro­ce­dures.
Results. The var­i­ous Populus ­clones and cul­ti­vars ­that ­were test­ed ­have ­shown dif­fer­ent ­degrees of tol­er­ance to the xen­o­bi­o­tic solu­tion ­obtained ­from the orig­i­nal con­tam­i­nat­ed ­site. Some ­clones ­have ­shown con­sis­tent respons­es ­both in ­situ and in con­trolled envi­ron­ment experi­men­tal set­tings. Of the ­plants pre­sent­ing ­high tol­er­ance, the ­most prom­is­ing cul­ti­var was “Dorskamp” (P. can­a­den­sis).
Conclusions. The pre­lim­i­nary ­results ­obtained in ­this ­study sug­gest ­that the devel­op­ment of reli­able meth­ods ­through the use of an ­array of ­plant selec­tion meth­ods is a ­viable ­approach to phy­tor­e­me­di­a­tion.
