In order to ensure the safe production of vegetables in Pb-contaminated farmland under the complex interactions of an extreme geological background area and human activities in Southwest China, 32 types of widely planted vegetable varieties in the southwest region were collected. Correlation analysis, multiple linear regression analysis, and other methods were used to study the accumulation of Pb in soil-vegetables and the key constraints. The threshold of soil Pb ecological security in farmland in southwest China was determined by the method of species sensitivity distribution. The results showed that (Pb) of the soils was 47.59-462.38 mg·kg, which was 1.88 times higher than that of the background value of soil Pb in Yunnan Province (90 mg·kg), and 68.40% of the soil samples exceeded the screening value of the "Soil Environmental Quality Agricultural Land Soil Pollution Risk Management Standard" (GB 15618-2018). The content of Pb in the edible parts of vegetable crops ranged from 0.02 to 0.49 mg·kg, and the exceeding rate reached 20.49%. Pb concentration in the vegetables was in the decreasing sequence of leafy vegetables > roots and stems vegetables > eggplant vegetables > edible bean vegetables > pepper vegetables. Based on soil pH, OM, and CEC, the model of Pb accumulation in vegetables was constructed, in which pH was the first critical factor affecting Pb accumulation in vegetables. The sensitivity index of vegetable Pb species showed that leafy vegetables, eggplant vegetables, and a small number of frame bean vegetables were less sensitive to Pb. The soil Pb classification thresholds of the three types (priority protection, safe use, and strict control) of areas for vegetable safety production was ≤ 100, 100-353, and ≥ 353 mg·kg, respectively.

Epidemiological evidence has shown that the regular ingestion of vegetables and fruits is associated with reduced risk of developing chronic diseases. The introduction of the 3Rs (replacement, reduction, and refinement) principle into animal experiments has led to the use of valid, cost-effective, and efficient alternative and complementary invertebrate animal models which are simpler and lower in the phylogenetic hierarchy.

Microplastics (MPs) pose an emerging threat to vegetable growing soils in Harbin, which have a relatively high abundance (11,065 n/kg) with 17.26 of potential ecological risk of single polymer hazard (EI) and 33.92 of potential ecological risk index (PERI).

Objectives: The aim of this study was to explore the association of fruit, vegetable, and pulses consumption with all-cause, cardiovascular, and cancer mortality.
Study Design: This prospective study included 66,933 individuals from three Spanish health surveys linked to the national death registry up to December 2022.
Methods: Adjusted Poisson regression models were used to analyze the data, categorizing fruit, vegetable and pulses intake according to Spanish dietary recommendations and using splines to examine non-linear relationships.

B vitamins are essential for energy metabolism, nervous health, blood production, and the immune system. Their quantification in nutritional supplements and food is mandatory to manage a correct daily intake and dosage. In this study, a fast and sustainable method for the analysis of 8 B vitamins (VB, VB, VB, nicotinamide, VB, VB, VB, VB) in real samples using a 2D-carbon microfiber fractionation system combined with a triple quadrupole mass spectrometer (2DμCFs-QqQ-MS/MS) is presented.
