- Abstract
Parsley is known in Lebanese diet for its nutraceutical properties and health benefits. However, the rising heavy metal contamination in irrigation water and agricultural soil affects crop production and safety. This study aims to assess parsley consumption in Lebanese population using a web-based food frequency survey, to measure cadmium accumulation and its effect on the physiology of parsley. Parsley was grown in soil for 9 weeks and exposed to different CdCl2 concentrations (0, 0.5, 2, 20, and 200 ppm). After harvesting, chlorophyll, sugar, and amino acid contents in parsley leaves were evaluated, and cadmium content was measured in soil, root, and shoot using inductively coupled plasma mass spectrometry. Estimated average daily consumption of parsley was 19.175 g/day. Cadmium content in parsley increased with increased cadmium soil concentration with higher increase in roots (47.648 ± 1.6 mg/kg) than shoots (1.522 ± 0.01 mg/kg) in the soil treated with 200 mg/kg of CdCl2. The study revealed that cadmium causes significant decrease in total fresh and shoot fresh weights and in chlorophylls a, b, and total chlorophyll. Cadmium-treated plants showed a significant increase in total sugar and amino acid contents suggesting the induction of a potential stress on the plant. Values of the bioconcentration factor and the translocation factor in parsley indicate the plant's capacity to accumulate cadmium. The target hazard quotient had a value < 1 suggesting plant cadmium remediation through phytostabilization, concentrating the metal in roots. Potentially, parsley remains safe for consumption with low risk to human health when grown in cadmium-polluted soils.
