Abstract <p>The residual concentration of the organochlorine pesticide lindane in model samples of tomatoes, cucumbers, and onions is studied by gas chromatography. A pesticide solution was added to soil, after which these plants were grown twice in the contaminated soil. Two sample preparation methods were used in the analysis: according to GOST 30349 and a similar procedure using liquid nitrogen at the homogenization stage. It was found that the use of liquid nitrogen in the sample preparation increased the recovery of the analytes by up to two times. For tomato and cucumber samples, it was found that both during primary and secondary plant cultivation, the residual amount of organochlorine pesticide increased with increasing pesticide concentration in spraying. However, this is not typical for onion samples. In the last case, the residual amounts of lindane decreased with increasing concentration of the initial analyte. Such behavior is typical for root crop samples, which do not include onion. The residual concentration of lindane in different parts of tomato and cucumber plants varied: tomato accumulated the pesticide to a greater extent in the fruit, and cucumber, in the tops. In re-cultivation in contaminated soil, the residual amount of lindane did not exceed 12% of the initial one. As a result, it was found that the most suitable plant for growing on lindane-contaminated soils is cucumber, because 80–90% of lindane is accumulated in inedible cucumber roots, and the fruits contain the smallest amount of the pollutant among all vegetables. Tomato is unsuitable for growing on contaminated soils, because the fruits accumulate significant amounts of lindane.</p>
